MariaDB Check Empty String

Here we will understand and learn how to use the MariaDB WHERE condition for checking the empty string of a table in a query. And it will be easy to explain it with the help of syntax and an example.

When executing the SELECT statement in MariaDB, the WHERE condition has been used to sort records in the results. It’s also used with commands like INSERT, DELETE, and UPDATE. The following syntax of the MariaDB WHERE condition for checking empty string by the following query:

SYNTAX:

SELECT expression FROM TABLE_NAME
WHERE COLUMN_NAME=' ';

First, let’s have a look at the MIT_STUDENTS table by the following query:

SELECT * FROM MIT_STUDENTS;

In this preceding query, we have used the SELECT statement to retrieve all records from the MIT_STUDENTS table.

Here is an illustrated example of the MariaDB WHERE condition for checking an empty string by the following query:

EXAMPLE:

SELECT * FROM MIT_STUDENTS
WHERE FIRST_NAME= ' ';

in this above query, we have used the SELECT statement to retrieve all records from the MIT_STUDENTS table with the help of the WHERE condition. In the WHERE condition, we have to select empty string records from the FIRST_NAME column.

If the WHERE condition gets executed, it will retrieve all records from the MIT_STUDENTSble by using the SELECT statement.

Suppose there is no empty string in the FIRST_NAME column then also the query will be executed. And there will be no output column.

In this section, we have understood how to find empty strings from the table by using just the WHERE condition in the query.

MariaDB Check Empty String But Not Null

In this section, we will learn and understand how to use the MariaDB WHERE condition for checking empty strings and also use the IS NOT NULL condition in a query. It is explained with the help of an illustrated example.

In MariaDB, the IS NOT NULL condition is used to check records that carried NULL in the column_name or expression from using the SELECT statement.

EXAMPLE:

SELECT * FROM MIT_STUDENTS 
WHERE FIRST_NAME=' ' 
AND PHYSICS IS NOT NULL;

In this query, we have used the SELECT statement to retrieve all records from the MIT_STUDENTS table by using the WHERE condition. In the WHERE condition, the FIRST_NAME column will select records that carry empty strings.

And the PHYSICS column doesn’t carry the NULL value as a number in the MIT_STUDENTS table.

So if the WHERE condition gets TRUE, then it will retrieve all records from the MIT_STUDENTS table by using the SELECT statement.

In this section, we have understood how to use the WHERE condition with the IS NOT NULL condition which helped to find the empty string from the MIT_STUDENTS table.

MariaDB Check Empty String But Not Empty

In this sub-topic, we will learn and understand how to use the MariaDB WHERE condition for checking empty strings with the NOT EQUAL operator in the query. It is explained with the help of an illustrated example.

In MariaDB, the NOT EQUAL operator is used to testify to nonequality in the query.

EXAMPLE:

SELECT * FROM MIT_STUDENTS 
WHERE FIRST_NAME != ' '
LIMIT 10;

• In this query, we have used the MariaDB SELECT statement to retrieve all records from the MIT_STUDENTS table with the WHERE condition.
• In the WHERE condition, we select records from the FIRST_NAME column which doesn’t carry an empty string.
• If the WHERE condition gets TRUE then it will retrieve all records from the MIT_STUDENTS table by the SELECT statement.
• At the end of the query, we have used the LIMIT clause as LIMIT 10 to retrieve all records from the MIT_STUDENTS table by using the SELECT statement.

In this sub-topic, we have understood the use of the NOT EQUAL operator in the WHERE condition for checking the empty string in the MIT_STUDENTS table.

MariaDB Check Empty String Count

We will learn and understand how to use the MariaDB WHERE condition with the COUNT function to check empty strings in the query. It is explained with the help of an illustrated example.

In MariaDB, the COUNT function is used to count the total number of rows of an expression or column_name in the query. Let’s see an example of the MariaDB COUNT function with the WHERE condition for checking empty strings by the following query:

EXAMPLE:

SELECT COUNT(*) FROM MIT_STUDENTS 
WHERE FIRST_NAME=' ';

In the MariaDB SELECT query, we have used the COUNT function on all the columns of the MIT_STUDENTS table by using the WHERE condition. In the COUNT function, it will count all records from the MIT_STUDENTS table.

In the WHERE condition, the FIRST_NAME column will carry all records whose names carry empty strings in the MIT_STUDENTS table.

If the WHERE condition is satisfied, it will retrieve all records from the MIT_STUDENTS te using the SELECT statement.

We have understood the MariaDB COUNT function with the WHERE condition for checking the empty string in the MIT_STUDENTS table. It may help us to understand how to check empty strings in the MIT_STUDENTS table.

MariaDB Check Empty String Contains Substring

We will learn and understand how to use the MariaDB SUBSTRING function with the BETWEEN condition which will be used to check empty strings in a query. And it is explained with the help of an illustrated example.

In MariaDB, the SUBSTRING function is used to extract a substring from the expression or column_name in the query. Let’s see the syntax of the MariaDB SUBSTRING function with the WHERE condition to check empty strings by the following query:

SYNTAX:

SELECT EXPRESSION,SUBSTRING(EXPRESSION,START_POSTITION, [FOR LENGTH]) FROM TABLE_NAME
WHERE COLUMN_NAME=' ';

The syntax explanation:

• START_POSITION: The position from which it will extract. The first position of the string will always 1.
• LENGTH: It is optional and the number of the characters to be extracted. If the parameters are removed then it will give the whole string.

Here is an illustrated example of the MariaDB SUBSTRING function with the WHERE condition to find an empty string by the following query:

EXAMPLE:

SELECT SUBSTRING(FIRST_NAME,2) FROM MIT_STUDENTS
WHERE FIRST_NAME=' ';

As we see in the above query, we have used the SUBSTRING function on the FIRST_NAME column of the MIT_STUDENTS table based on the WHERE condition. In the SUBSTRING function, it will subtract from 2 in the FIRST_NAME column of the MIT_STUDENTS table.

In the WHERE condition, the FIRST_NAME will select records that carry empty strings in the MIT_STUDENTS table.

If the WHERE condition is satisfied, it will retrieve all records from the MIT_STUDENTS te by using the SELECT statement.

Note that the SUBSTRING function can’t provide substring from the FIRST_NAME column because of the WHERE condition. In the WHERE condition, the FIRST_NAME column was needed to find the empty string from the MIT_STUDENTS table.

This section helps us to understand how to check empty strings in the MIT_STUDENTS table by using the SUBSTRING function with the WHERE condition.

MariaDB Check Empty String Coalesce

In this section, we will understand and learn how to use the MariaDB COALESCE function to check an empty string in the query. And it will be easy to explain it with the help of an illustrated example.

In MariaDB, the COALESCE function is used to return NON-NULL expression from the expressions or column_names in the query. Let’s see the syntax of the MariaDB COALESCE function to find an empty string by the following query:

SYNTAX:

SELECT COALESCE(expression_1,expression_n,expression_n) FROM TABLE_NAME;

The syntax explanation:

• expression_1, expression_2,expression_n: It is used to test NON-NULL values in the expression or column_name of the table.

Here is a sample example of the MariaDB COALESCE function to find an empty string in the table by the following query:

EXAMPLE:

SELECT COALESCE(PHYSICS,'Empty String') AS EMPTY_FIRSTNAME, 
PHYSICS, MATHS
FROM MIT_STUDENTS;

In this query, we have used the COALESCE function on the PHYSICS column from the MIT_STUDETNS table. We have also selected the records of the PHYSICS and MATHS columns from the MIT_STUDENTS table by using the SELECT statement.

In the COALESCE function, it replaced the NULL value with the EMPTY STRING value for every record of the PHYSICS column in the MIT_STUDENTS table.

In this sub-topic, we have used the COALESCE function is used to find empty strings in the query. We hope that the example made it easy to understand the concept of checking the empty strings of the MIT_STUDENTS table.

MariaDB Check Empty String Date

Here we will understand and learn how to use the MariaDB DATE function with the WHERE condition for checking empty strings in the table by the query. And it is explained with the help of an illustrated example.

In MariaDB, the DATE function is used to extract a date from the date value or DateTime expression or column_name in the query. Let’s use an example of the MariaDB DATE function with the WHERE condition by the following query:

EXAMPLE:

SELECT DATE(JOINING_DATE),FULL_NAME FROM FAZZRO_COMPANY
WHERE FULL_NAME=' ';

In this preceding query, we have used the DATE function on the JOINING_DATE column in the FAZZRO_COMPANY table. We have also selected all records of the FULL_NAME column by using the SELECT statement.

In the WHERE condition, the FULL_NAME column will catch records that carry empty strings in the FAZZRO_COMPANY table. If the WHERE condition is TRUE, it will retrieve all records from the FAZZRO_COMPANY table using the SELECT statement.

In this tutorial, we have understood how to use the MariaDB DATE function with the WHERE condition to find an empty string in the table. For the explanation part, we have used an example.

MariaDB Check Empty String Exists

In this section, we will learn and understand how to use the MariaDB EXISTS condition on a subquery. We also use the WHERE condition in a subquery and which is explained with the help of an illustrated example.

When the MariaDB EXISTS condition is used with a subquery, it is said to be “met” if the inner select statement returns at least one record. Under a SELECT, INSERT, UPDATE, or DELETE statement, it can be utilized. Let’s an example of the MariaDB EXISTS statement with the WHERE condition by the following query:

EXAMPLE:

SELECT FULL_NAME FROM FAZZRO_COMPANY
WHERE EXISTS
(SELECT * FROM FAZZRO_COMPANY
WHERE FULL_NAME= '  ');

In the OUTER SELECT statement, we select all records of the FULL_NAME column from the FAZZRO_COMPANY table by using the WHERE condition. Whereas in the EXISTS statement, we select all records from the FAZZRO_COMPANY table based on the WHERE condition.

In the WHERE condition, the FULL_NAME column will select an empty string from the FAZZRO_COMPANY table. If the WHERE condition gets TRUE, it will retrieve all records from the FAZZRO_COMPANY table using the SELECT statement.

If the WHERE EXISTS statement condition gets TRUE then it will retrieve all records from the FAZZRO_COMPANY table.

In this section, we hope that you have understood how to use the MariaDB EXISTS statement with the WHERE condition for checking empty strings in a query. We have used a sample example to explain it properly.

MariaDB Check Empty String Greater Than

In this sub-topic, we will understand and learn how to use the MariaDB WHERE condition with the GREATER THAN operator in the query. And it is explained with the help of an illustrated example.

In MariaDB, the GREATER THAN operator is used after the WHERE condition which will retrieve records after selecting from the SELECT statement. It is also used in the UPDATE, DELETE and INSERT statements. The main use of the GREATER THAN operator is used to find greater value from numbers in the WHERE condition.

Here is an example of the MariaDB WHERE condition with the GREATER THAN operator to find an empty string in a table by the following query:

EXAMPLE:

SELECT * FROM fazzro_company 
WHERE FULL_NAME= '  '  
AND ID>10;

In this query, we have used the SELECT statement to retrieve all records from the FAZZRO_COMPANY table by using the WHERE condition. In the WHERE condition, the FULL_NAME column will select an empty string from the FAZZRO_COMPANY table.

And in the ID column, it will select values greater than 10 from the FAZZRO_COMPANY table. If the WHERE condition gets fulfilled, it will retrieve all records from the FAZZRO_COMPANY te by using the SELECT statement.

In this tutorial, we have understood how to use the MariaDB WHERE condition with the GREATER THAN operator to find an empty string in a table. For better understanding, we have used an example.

MariaDB Check Empty String Group By

In this section, we will understand and learn how to use the MariaDB BETWEEN condition with the GROUP BY clause for checking empty strings in the table from the query. It is explained with the help of an illustrated example.

The group by clause in MariaDB divides a result’s rows into categories. The aggregate functions count(), min(), max(), sum(), and avg() are frequently used with the group by function to obtain attributes of groups. For example, the number of elements (count), the total of values (sum), the maximum element (max), the minimum element (min), and the average of elements (avg).

Here is a sample example of the MariaDB BETWEEN condition with the GROUP BY clause in a query by the following example:

EXAMPLE:

SELECT FULL_NAME,JOINING_DATE FROM FAZZRO_COMPANY
WHERE FULL_NAME= ' ' 
GROUP BY JOINING_DATE;

In this preceding query, we have used the SELECT statement to select records of the FULL_NAME and JOINING_DATE columns from the FAZZRO_COMPANY table based on the WHERE condition. In the WHERE condition, the FULL_NAME column will select an empty string from the FAZZRO_COMPANY table.

And grouped them by the JOINING_DATE column by using the GROUP BY clause. If the WHERE condition gets executed, it will retrieve all records from the FAZZRO_COMPANY te by using the SELECT statement.

In this section, we have used the MariaDB BETWEEN condition with the GROUP BY clause which was used to check empty strings in a table by the query. And it is easy to explain with the help of an illustrated example.

MariaDB Check Empty String In

In this section, we will learn and understand how to use the MariaDB WHERE condition with the IN condition for checking empty strings in the table. And it is explained with the help of an illustrated example.

In a SELECT, INSERT, UPDATE, or DELETE query, the MariaDB IN condition is being used to help avoid the requirement for several OR conditions. Let’s see an example of the MariaDB BETWEEN condition with the IN condition for checking an empty string in a table by the following query:

EXAMPLE:

SELECT FULL_NAME,JOINING_DATE 
FROM FAZZRO_COMPANY 
WHERE FULL_NAME IN(' ' ,' ');

As we see in the above query, we have used the SELECT statement to select the FULL_NAME and JOINING_DATE columns from the FAZZRO_COMPANY table used with the WHERE condition.

In the WHERE condition, the FULL_NAME column will return all records from the FAZZRO_COMPANY table which carries an empty string in that column of the table. If the WHERE condition gets TRUE, it will retrieve all records from the FAZZRO_COMPANY le using the SELECT statement.

In this section, we have understood to check an empty string in the table by using the WHERE condition with the IN condition in the query.

MariaDB Check Empty String JSON

We will learn and understand how to use the MariaDB BETWEEN conditions on the JSON value in the query. It is explained with the help of an illustrated example.

MariaDB’s JSON data type is a replacement for LONGTEXT, which was designed to work with MySQL’s JSON data type. Because it violates the SQL standard, MariaDB supports the JSON data format as a LONGTEXT instead, and MariaDB’s benchmarks show that efficiency is at least comparable.

Here is a sample example of the MariaDB WHERE condition with the JSON data type by the following query:

EXAMPLE:

SELECT * FROM json_demo
WHERE USER_NAME='';

In this preceding query, we used the SELECT statement to retrieve all records from the JSON_DEMO table and used the WHERE condition. In the WHERE condition, we have used the USER_NAME column with the equal operator to find an empty string in the JSON data type.

If the WHERE condition gets TRUE, it will retrieve all records from the JSON_DEMO le by using the SELECT statement.

In this section, we hope that you have understood how to use the WHERE condition on the JSON data type to find an empty string in the JSON_DEMO table from the query.

MariaDB Check Empty String Max

In this section, we will understand and learn how to use the MariaDB MAX function with the BETWEEN condition to find an empty string in the query. It is explained with the help of an illustrated example.

In MariaDB, the MAX function is used to find the max value from the expression or column_name in the query. Let’s see an example of the MariaDB MAX function with the BETWEEN condition to find an empty string by the following query:

EXAMPLE:

SELECT *,MAX(ID) FROM FAZZRO_COMPANY
WHERE FULL_NAME='  ';

In this query, we have used the SELECT statement to retrieve all records from FAZZRO_COMPANY. And we have also used the MAX function on the ID column to find the highest value of id in the FAZZRO_COMPANY table.

In the WHERE condition, the FULL_NAME column is used with the EQUAL operator to find an empty string in the FAZZRO_COMPANY table. If the WHERE condition gets executed, it will retrieve all records from the FAZZRO_COMPANY te by using the SELECT statement.

In this sub-topic, we have understood how to use the MariaDB MAX function with the BETWEEN condition to find the empty string in the FAZZRO_COMPANY table by the query.

MariaDB Check Empty String Min

In this section, we will understand and learn how to use the MariaDB MIN function with the BETWEEN condition to find an empty string in the query. It is explained with the help of an illustrated example.

In MariaDB, the MIN function is used to find the min value from the expression or column_name in the query. Let’s see an example of the MariaDB MIN function with the BETWEEN condition to find an empty string by the following query:

EXAMPLE:

SELECT *, MIN(ID) FROM FAZZRO_COMPANY
WHERE FULL_NAME='  ';

In this query, we have used the SELECT statement to retrieve all records from FAZZRO_COMPANY. And we have also used the MIN function on the ID column to find the lowest value of id in the FAZZRO_COMPANY table.

In the WHERE condition, the FULL_NAME column is used with the EQUAL operator to find an empty string in the FAZZRO_COMPANY table. If the WHERE condition gets TRUE,t, it will retrieve all records from the FAZZRO_COMPANY table using the SELECT statement.

In this sub-topic, we have understood how to use the MariaDB MIN function with the BETWEEN condition to find the empty string in the FAZZRO_COMPANY table by the query.

MariaDB Check Empty String Order By

In this section, we have understood and learned how to use the MariaDB WHERE condition with the ORDER BY clause to find an empty string in the query. And we have used an example to explain it in detail.

The ORDER BY clause in MariaDB is used to sort the records in the result set in ascending or descending order. Let’s look at a query that uses the MariaDB WHERE condition and the ORDER BY clause to identify an empty string:

EXAMPLE:

SELECT * FROM FAZZRO_COMPANY
WHERE FULL_NAME='  '
ORDER BY ID DESC;

In this preceding query, we have selected all records from the FAZZRO_COMPANY table by using the SELECT statement. The FULL_NAME column found an empty string in the FAZZRO_COMPANY table by using the EQUAL operator in the WHERE condition.

And we have arranged the ID column in descending order by using the ORDER BY clause.If the WHERE condition is TRUE, the SELECT statement will fetch all records from the FAZZRO_COMPANY table.

We expect that the MariaDB BETWEEN condition is combined with the ORDER BY clause in this section to detect an empty string in the query.

MariaDB Check Empty String Partition

We’ll learn how to utilize the MariaDB PARTITION BY clause with the WHERE condition to find an empty text in a query in this section. It’s also demonstrated by an example.

To separate table rows into groups, the MariaDB PARTITION BY clause is utilized. It’s useful for doing calculations on single rows of a group using rows from the same group.

• It is always used in conjunction with the OVER() clause.
• Window refers to the partition created by the partition clause.
• This clause only applies to Windows functions. RANK(), LEAD(), LAG(), and so on.
• If this clause in the OVER() clause is omitted, the entire table is treated as a single partition.

Here’s an example of how to use the PARTITION BY clause in conjunction with the BETWEEN condition to discover an empty text in a query:

EXAMPLE:

SELECT FULL_NAME, MAX(ID) OVER (PARTITION BY FULL_name) 
 AS MAX_BY_NAME FROM FAZZRO_COMPANY
 WHERE FULL_NAME=' ';

We used the SELECT statement in the previous query to select all records in the FAZZRO_COMPANY table using the FULL_NAME field. In the MAX function, we utilized the max function on the ID column and the OVER clause to partition the FAZZRO_COMPANY database by the FULL_NAME column.

The FULL_NAME column was used in the WHERE condition to find an empty string in the FAZZRO_COMPANY table using the EQUAL operator. The SELECT query will select all entries from the FAZZRO_COMPANY table if the WHERE condition evaluates to true. 

In this sub-topic, we learned how to utilize the MariaDB PARTITION BY clause and the BETWEEN condition to find an empty string in the FAZZRO_COMPANY table. To further explain it, we utilized the example above.

MariaDB Check Empty String Substring

In this lesson, we’ll learn how to utilize the SUBSTRING function in conjunction with the WHERE condition to identify empty strings in a table. It’s also described with the help of an illustration.

The SUBSTRING function in MariaDB is used to extract a substring from a string in a column or expression returned by a query. Let’s look at a query that uses the MariaDB SUBSTRING function and the WHERE condition to locate empty strings:

EXAMPLE:

SELECT ID,JOINING_DATE,SUBSTRING(FULL_NAME) AS SUBSTRING_NAME FROM FAZZRO_COMPANY
WHERE FULL_NAME='  ';

The SELECT statement was used to select all records from the FAZZRO_COMPANY database from the ID and JOINING_DATE columns, as seen in the preceding query. In the FAZZRO_COMPANY table, we also utilized the SUBSTRING function on the FULL_NAME column to locate empty strings.

We used the ALIAS clause with the AS keyword to shorten the name of the function_name and designated the output column SUBSTRING_NAME. The FULL_NAME column was used with the EQUAL operator in the WHERE condition to locate empty strings in the FAZZRO_COMPANY table.

If the WHERE condition is TRUE, the SELECT statement will fetch all records from the FAZZRO_COMPANY table.

We learned how to utilize the SUBSTRING function with the WHERE condition to identify empty strings in a query in this part. We hope that the concept of finding an empty string in the FAZZRO_COMPANY table is clear.

MariaDB Check Empty String To 0

Here we will understand and learn how to check empty strings by the INSERT INTO statement in MariaDB. And we will explain it with the help of an illustrated example.

EXAMPLE:

INSERT INTO FAZZRO_COMPANY (ID,FULL_NAME, JOINING_DATE, EXPIRING_DATE)
VALUES (12,' ', '2021-02-18','2022-04-08');

By default, MariaDB tries to convert incorrect column values to the correct type. The empty string ” is of the string type, which is neither an integer nor a NULL value. We recommend that you do the following steps:

• First, we have to change the query into the following query:
  • INSERT INTO FAZZRO_COMPANY (FULL_NAME) VALUES (' ');

• Then we must enable STRICT MODE in the MariaDB software’s MySQL .cnf file, which will prevent as many unintentional types and value conversions as feasible. We’ll get more error messages if we try to get something MySQL doesn’t expect, which will help you find problems faster.
• Into the .cnf file, we will write a statement as given below:
  • Then save the .cnf file, and it will be easy to discover issues with the table’s NULL or INTEGER values.

sql_mode=NO_ENGINE_SUBSTITUTION

We expect that by combining the INSERT INTO command with the STRICT MODE of the .cnf file, we can achieve our goal. We hope that satisfied you and that the concept of testing an empty string into the FAZZRO_COMPANY table was clear.

MariaDB Check Empty String Update

We’ll learn how to utilize the UPDATE command in MariaDB to check for empty strings in a table. And we will also describe it with the help of an example.

In MariaDB, the UPDATE statement is used to update the existing record of the table. Here is a sample example of the UPDATE statement to check an empty string by the following query:

EXAMPLE:

update FAZZRO_COMPANY SET FULL_NAME='  ' 
WHERE LENGTH(FULL_NAME)=0;

SELECT * FROM FAZZRO_COMPANY;

• With the WHERE condition, we used the UPDATE statement to set the FULL_NAME column to empty string in the above query.
• We utilized the LENGTH function on the FULL_NAME column in the WHERE condition and kept the value 0 from the FAZZRO_COMPANY table.
• The UPDATE statement will set the record of the FULL_NAME column to an empty string if the WHERE condition is TRUE.
• We’ll use the SELECT query to get all records from the FAZZRO_COMPANY table if we wish to check that updated component of the FULL_NAME column.

So, we think that utilizing the UPDATE statement, the concept of checking for empty strings in the FAZZRO_COMPANY table is clear. We presented an example and discussed everything in-depth to help you understand.

MariaDB Check Empty String Year

We will learn how to utilize the MariaDB YEAR function with the WHERE condition to discover empty strings in the table by query in this MariaDB tutorial. To better explain it, we shall give an illustrative example.

In MariaDB, the YEAR function is used to extract the year values from the date or DateTime column from the table. The following query uses the MariaDB YEAR function in conjunction with the WHERE condition to identify empty strings in the table:

EXAMPLE:

SELECT YEAR(JOINING_DATE) AS YEAR_VALUE,FULL_NAME FROM FAZZRO_COMPANY
WHERE FULL_NAME= ' ';

In this preceding query, we have used the YEAR function on the JOINING_DATE column from the FAZZRO_COMPANY table. We have also selected all records of the FULL_NAME column from the FAZZRO_COMPANY table by using the SELECT statement.

We grabbed the year value from the JOINING_DATE column using the YEAR function. To make the function_name shorter, we utilized the ALIAS clause with the AS keyword to make the output column’s name YEAR_VALUE.

The FULL_NAME is used with the EQUAL operator in the WHERE condition to find empty strings in the FAZZRO_COMPANY table.

If the WHERE condition is TRUE, the SELECT statement will fetch all records from the FAZZRO_COMPANY table.

We’re expecting that the YEAR function will be used in conjunction with the WHERE condition to locate empty strings in the FAZZRO_COMPANY table. We used an example and explained it in-depth to help you understand.
