MariaDB Create Temporary Table From Select

Here we will learn and understand how to use the MariaDB INSERT INTO SELECT statement for creating a temporary table of the existing table by the query. And which will be explained with the help of an illustrated example.

In MariaDB, a temporary table is a particular type of table which is allowed to store a temporary result set and which can also be reused several times in a single session. And a TEMPORARY table becomes very difficult to handle when we use the SELECT statement with the JOIN clause to query data for the result set.

In these cases, we can use the temporary table for the immediate result and use another query to process it. Here are specialized features of the temporary table as shown following:

• To create a temporary table, it is used by CREATE TEMPORARY TABLE statement. Note that the TEMPORARY keyword is added between the CREATE and TABLE keywords.
• MariaDB removes the temporary table automatically when the session ends or the connection is terminated. We can of course use the DROP TABLE statement explicitly when the table is of no use.
• In the same session, we can’t create two temporary tables with the same name. A temporary table is accessible and available to the client who has made it. The different client creates a different temporary table with the same name without error because only the client who created a temporary table can use it.

Let’s see the syntax of how to create a temporary table from the SELECT statement in the following query:

SYNTAX:

CREATE TEMPORARY TABLE TEMPORARY_NAME(
COLUMN_NAME DATATYPE_DEFINE,
COLUMN_NAME_1 DATATYPE_DEFINE_2,
..... ,
COLUMN_NAME_N DATATYPE_DEFINITION);

INSERT INTO TEMPORARY_TABLE(COLUMN_NAME, COLUMN_NAME_2, ...... ,COLUMN_NAME_N)
SELECT EXPRESSION_1, EXPRESSION_2, EXPRESSION_N
FROM EXISTING_TABLE
WHERE [CONDITIONS];

EXAMPLE:

CREATE TABLE US_STATES(
STATE_ID INT AUTO_INCREMENT PRIMARY KEY,
STATE_NAME VARCHAR(50),
STATE_SHORTFORM VARCHAR(50),
STATE_POPULATION ENUM('HIGH','MEDIUM','LOW'));

INSERT INTO US_STATES(STATE_ID,STATE_NAME,STATE_SHORTFORM,STATE_POPULATION)
SELECT * FROM STATES_OF_USA
WHERE STATE_ID>0;

In the aforementioned query, we have created a temporary table called US_STATES on the existing table as STATES_OF_USA. It carries column_name as STATE_ID, STATE_NAME, STATE_SHORTFORM and STATE_POPULATION.

In the second query, we have used the INSERT INTO SELECT statement to forward the records of all columns from the STATES_OF_USA table into the US_STATES table based on the WHERE condition. In the WHERE condition, the STATE_ID column is used with the GREATER THAN operator to find a value greater than 0 from the STATES_OF_USA table.

This means that all records will be existed based on the SELECT statement for the US_STATES table. And it can be used based on the client’s work.

We hope that you have understood the subtopic “MariaDB Create Temporary Table From Select” by using the INSERT INTO SELECT statement on the table by the query. For a better explanation, we have used an example and explained it in depth.

MariaDB Create Temporary Table From Select Example

Here we will learn and understand how to use MariaDB CREATE TEMPORARY TABLE and INSERT INTO SELECT statements to create a temporary table for the existing table by the following query:

EXAMPLE:

CREATE TEMPORARY TABLE CUSTOMER(
ID INT,
FIRST_NAME VARCHAR(50),
LAST_NAME VARCHAR(50),
EMAIL VARCHAR(50),
PRICE INT);

INSERT INTO CUSTOMER(ID,FIRST_NAME,LAST_NAME,EMAIL,PRICE)
SELECT * FROM CUSTOMER_LIST
WHERE ID>1;

As we see in the above query, we have created a temporary table called CUSTOMER on the existing table as CUSTOMER_LIST. In the temporary tables, it carries the ID, FIRST_NAME, LAST_NAME, EMAIL and PRICE columns in the CUSTOMER table with datatype VARCHAR and INT datatype.

And to insert all records of all the columns from the existing table to a temporary table, we have used the INSERT INTO SELECT statement with the WHERE condition. In the WHERE condition, the ID column is used with the GREATER THAN operator to find a value greater than 1 from the CUSTOMER_LIST table and get exist into the CUSTOMER table.

If the WHERE condition turns out to be TRUE then the SELECT statement will retrieve all records from the CUSTOMER table. But if the SELECT statement gets executed and can’t put all records into the CUSTOMER table then it will happen because of the WHERE condition.

We hope that you have understood the subtopic “MariaDB Create Temporary Table From Select Example” by using the MariaDB CREATE TEMPORARY TABLE and INSERT INTO SELECT statements for creating a temporary table on the existing table by the query. We have used an example and explained it in depth, for better understanding.

MariaDB Create Temporary Table From Select By Id

Here we will learn and understand how to create a temporary table from the SELECT statement to select the ID column from the table by the query, which will be explained with the help of an illustrated syntax.

EXAMPLE:

CREATE TEMPORARY TABLE USASTATES(
STATE_ID INT PRIMARY KEY);

INSERT INTO USASTATES(STATE_ID)
SELECT STATE_ID FROM STATES_OF_USA;

SELECT * FROM USASTATES;

As we see in the above query, we have created a temporary table called USASTATES on the existing table as STATES_OF_USA. In the temporary table, it carries the STATE_ID column in the USASTATES table with the datatype as INT and PRIMARY KEY constraint.

To insert the records of the existing table into the temporary table, we have used the INSERT INTO SELECT statement which is shown in the above query. Once the INSERT INTO SELECT statement execution has been done, we can use the SELECT statement to retrieve all records from the USASTATES temporary table.

We hope that you have understood how to create a temporary table from the SELECT statement to retrieve the ID column from the existing table into the temporary table by the query. For a better explanation, we have used a sample example and explained it in depth.

EXAMPLE:

CREATE TEMPORARY TABLE USASTATES(
STATE_NAME VARCHAR(50));

INSERT INTO USASTATES(STATE_NAME)
SELECT STATE_NAME FROM STATES_OF_USA;

SELECT * FROM USASTATES;

In the aforementioned query, we have created a temporary table called USASTATES on the existing table as STATES_OF_USA. It carried out the STATE_NAME column with the datatype as VARCHAR(50).

Then we used the INSERT INTO SELECT statement to transfer the records of the STATE_NAME column in the USASTATES temporary table. If we want to check new records have been transferred to the USASTATES temporary table then use the SELECT statement.

MariaDB Create Temporary Table From Select Count

In this MariaDB subtopic tutorial, we will learn and understand how to create a temporary table from the SELECT statement with the COUNT clause on the table by the query, which will be explained with the help of a sample example.

EXAMPLE:

CREATE TEMPORARY TABLE USA_MIT_UNIVERSITY
SELECT COUNT(*) AS TEMP_COUNT FROM MIT_STUDENTS;

SELECT * FROM USA_MIT_UNIVERSITY;

In the first query, we used the CREATE TEMPORARY TABLE statement to create a temporary table called USA_MIT_UNIVERSITY table. On which, we used the SELECT statement with the COUNT function from the MIT_STUDENTS table.

In the COUNT function, it will count the total number of rows from the MIT_STUDENTS table and transfer the result set to the temporary table as the USA_MIT_UNIVERSITY table. And to shorter the function_name, we have used the ALIAS clause with the AS keyword and given the name as the TEMP_COUNT column for the output result set.

If we want to check all new records are there in the USA_MIT_UNIVERSITY table then we will use the SELECT statement to retrieve the records from the above query.

We hope that you have understood the subtopic “MariaDB Create Temporary Table From Select Count” by using the MariaDB CREATE TEMPORARY TABLE statement on the table by the query. For a better description, we have used a sample and described it in profundity.

MariaDB Create Temporary Table From Select Distinct

Here we will learn and understand how to create a temporary table from the SELECT statement with the DISTINCT clause on the table by the query, which will be explained with the help of a sample example.

In MariaDB, the DISTINCT clause is used to remove the duplicate values from the result set by using the SELECT statement.

EXAMPLE:

CREATE TEMPORARY TABLE COMPANY_PERSONALDETAIL
SELECT DISTINCT PERSON_NAME,MALE_FEMALE,IP_ADDRESS FROM PERSONAL_DETAIL;

SELECT * FROM COMPANY_PERSONALDETAIL;

In the aforementioned query, a temporary table is created called COMPANY_PERSONALDETAIL by using the CREATE TEMPORARY TABLE statement. Then we used the SELECT statement to retrieve all records of the MALE_FEMALE and IP_ADDRESS columns from the PERSONAL_DETAIL table. In the DISTINCT clause, it will remove the duplicate person name from the PERSON_NAME column in the PERSONAL_DETAIL table.

This means that once the SELECT statement execution works successfully and retrieves all records from the PERSONAL_DETAIL table then only it will transfer all records to the COMPANY_PERSONALDETAIL temporary table.

If we want to check and retrieve all records from the COMPANY_PERSONALDETAIL table then we will use the SELECT statement in the above query for the result set.

We hope that you have understood the subtopic “MariaDB Create Temporary Table From Select Distinct” by using the MariaDB CREATE TEMPORARY TABLE and SELECT statements on the table by the query. For a better understanding, we have used an example and explained it in depth.

MariaDB Create Temporary Table From Select Having

We will learn and understand how to use the CREATE TEMPORARY TABLE from the SELECT statement with the HAVING clause on the table which will create a temporary table by the query, which will be explained with the help of a sample example.

To limit the groups of returned rows to only those whose condition is TRUE, the MariaDB HAVING clause is combined with the GROUP BY clause. And the COUNT function is used to return the total count of an expression or column_name by the query.

EXAMPLE:

CREATE TEMPORARY TABLE USA_HARVARD
SELECT STUDENT_ID,COUNT(*) 'NUMBER OF STUDENTS' FROM HARVARD_UNIVERSITY
WHERE STUDENT_ID>=1
GROUP BY STUDENT_ID
HAVING COUNT(*)>=1;

SELECT * FROM USA_HARVARD;

As we see in the above query, we have created a temporary table called USA_HARVARD on the HARVARD_UNIVERSITY table by using the CREATE TEMPORARY TABLE statement. Then we used the SELECT statement to retrieve all records from the STUDENT_ID column from the HARVARD_UNIVERSITY table with the WHERE condition.

In the COUNT function, it will return the total count of an expression or column_name by the query. In the WHERE condition, the STUDENT_ID column is used with the GREATER THAN or EQUAL TO operator to find a value greater than or equal to 1 from the HARVARD_UNIVERSITY table.

Then we used the GROUP BY clause to group the records of the STUDENT_ID column and by using the HAVING clause with the COUNT function to find a value greater than or equal to 1 from the HARVARD_UNIVERSITY table.

If the WHERE condition turns out to be TRUE then the SELECT statement will retrieve all records from the HARVARD_UNIVERSITY table. But if the SELECT statement gets executed successfully and retrieves an empty record set from the HARVARD_UNIVERSITY table only when the WHERE condition gets a FALSE value.

The whole process of the first query is that with the help of the SELECT statement, it will retrieve and transfer all new records into the USA_HARVARD temporary table. But if we want to check if new records have been transferred or not the USA_HARVARD temporary table then we will use the SELECT statement to retrieve all records from the result set.

We hope that you have understood the subtopic “MariaDB Create Temporary Table From Select Having” by using the MariaDB CREATE TEMPORARY TABLE and SELECT statements on the table by the query. For a better experience, we have used an example and clarified it in deepness.

SELECT * FROM SKULLCANDY_USA
WHERE NOT EXISTS 
(SELECT * FROM SKULLCANDY
WHERE skullcandy.ID = skullcandy_usa.SKULLCANDY_ID);

SELECT * FROM USA_EARPHONE_COMPANY;

In the preceding query, we have created a temporary table called USA_EARPHONE_COMPANY temporary table from the existing table as SKULLCANDY_USA and SKULLCANDY tables. Then we used the SELECT statement to retrieve all records from the SKULLCANDY_USA table with the WHERE NOT EXISTS condition.

In the WHERE NOT EXISTS condition, the SELECT statement will retrieve all records from the SKULLCANDY table with the WHERE condition. In the WHERE condition, the ID column of the SKULLCANDY table and the SKULLCANDY_ID column of the SKULLCANDY_USA table are used with the EQUAL TO operator to find match each column of both tables with one another.

And with the WHERE NOT EXISTS clause, it will try to meet if the subquery will return one row from the table by the query. If we want to check all new records from the existing table have been transferred to the USA_EARPHONE_COMPANY temporary table then we will use the SELECT statement to receive it for the output result set.

EMPLOYEE_LIFE.LAST_NAME, EMPLOYEE_LIFE.FULL_NAME
FROM EMPLOYEE_DATA
INNER JOIN EMPLOYEE_LIFE
ON EMPLOYEE_LIFE.EMP_ID= EMPLOYEE_DATA.EMP_ID
WHERE EMPLOYEE_LIFE.EMP_ID>=5;

SELECT * FROM EMPLOYEE;

In the aforementioned query, a temporary table is created called EMPLOYEE_DETAILS on both tables EMPLOYEE_DATA and EMPLOYEE_LIFE tables by using the CREATE TEMPORARY TABLE statement.

Then we used the SELECT statement to retrieve all records from the EMP_FIRST_NAME, EMP_LAST_NAME, FIRST_NAME, LAST_NAME and FULL_NAME columns from both tables i.e; EMPLOYEE_LIFE and EMPLOYEE_DATA tables.

On the INNER JOIN clause, the EMPLOYEE_LIFE table is joined to the EMPLOYEE_DATA table based on the ON condition. In the ON condition, the common column as EMP_ID column is used with the EQUAL TO operator which makes the inner join on both tables i.e; EMPLOYEE_LIFE and EMPLOYEE_DATA tables.

In the WHERE condition, the EMP_ID column is used with the GREATER THAN or EQUAL TO operator to find a value greater than or equal to 5 from the EMPLOYEE_LIFE table. If the WHERE condition turns out to be TRUE then the SELECT statement will retrieve all records from the EMPLOYEE_LIFE table otherwise vice-versa.

This means that once the JOIN clause works and makes a connection between both tables i.e; EMPLOYEE_LIFE and EMPLOYEE_DATA tables. The SELECT statement will obtain all entries from the EMPLOYEE DETAILS temporary table for the temporary session in the MariaDB Server if we want to inspect the temporary table that is made on the JOIN clause of the table.

MariaDB Create Temporary Table From Select Where Clause

Here we will learn how to create a temporary table from the SELECT statement with the WHERE clause on the table by the query, which will be explained with the help of a sample example.

In MariaDB, the WHERE condition is used to sift the results set in the SELECT statement. It is also used with the DELETE, UPDATE or INSERT statement.

EXAMPLE:

CREATE TEMPORARY TABLE ANTHEM_COMPANY(
PATIENT_ID INT , 
PATIENT_FIRSTNAME VARCHAR(50), 
PATIENT_LASTNAME VARCHAR(50),
EMAIL VARCHAR(50),
GENDER VARCHAR(50), 
PATIENT_ENTRYDATE DATE);

INSERT INTO ANTHEM_COMPANY(PATIENT_ID,PATIENT_FIRSTNAME,PATIENT_LASTNAME,EMAIL,GENDER,PATIENT_ENTRYDATE)
SELECT PATIENT_ID,PATIENT_FIRSTNAME,PATIENT_LASTNAME,EMAIL,GENDER,PATIENT_ENTRYDATE FROM USA_ANTHEM_COMPANY
WHERE PATIENT_ID>=10;

SELECT * FROM ANTHEM_COMPANY;

In the preceding query, we have used the CREATE TEMPORARY TABLE statement to create a temporary table called ANTHEM_COMPANY from the existing table i.e; USA_ANTHEM_COMPANY table. In the temporary table, it carries all the column names which are the same and with the datatype as INT, VARCHAR and DATE.

To insert new records into the temporary table from the existing table, we have used the INSERT INTO SELECT statement on the ANTHEM_COMPANY table with the WHERE condition. In the WHERE condition, the PATIENT_ID column is used with the GREATER THAN or EQUAL TO operator to find a value greater than or equal to 10 from the USA_ATHEM_COMPANY table.

If the WHERE condition turns out to be TRUE then the SELECT statement will retrieve all records from the USA_ANTHEM_COMPANY table and transfer them into the ANTHEM_COMPANY table.

But if the SELECT statement executes successfully and retrieves empty an record set from the USA_ANTHEM_COMPANY table then only the new record will be able to transfer to the ANTHEM_COMPANY temporary table because the WHERE condition gets a FALSE value.

If we want to check new records have been entered into the ANTHEM_COMPANY temporary table then we will use the SELECT statement.

We hope that you have understood the subtopic “MariaDB Create Temporary Table From Select Where Clause” by using the MariaDB CREATE TEMPORARY TABLE and INSERT INTO SELECT statement on the table by the query. For a better understanding, we have used an example and explained it in deepness.

SELECT * FROM FAZZRO_COMPANY;

In the preceding query, we have created a temporary table called FAZZRO_COMPANY from the existing table as the USA_FAZZRO_COMPANY table by using the CREATE TEMPORARY TABLE statement. Then we used the SELECT statement to retrieve all records from the JOINING_DATE and EXPIRING_DATE columns from the USA_FAZZRO_COMPANY table.

In the DISTINCT clause, it will remove the duplicate values from the FULL_NAME column from the USA_FAZZRO_COMPANY table with the WHERE condition. In the WHERE condition, the ID column is used with the IS NULL condition to find a NULL value from the JOHNS_HOPKINS_HOSPITAL table.

In the end, we have used the LIMIT clause as LIMIT 5 to retrieve the first 5 records from the USA_FAZZRO_COMPANY table. This means that once the SELECT statement is executed successfully then it will transfer all records from the FAZZRO_COMPANY temporary table.

If we want to retrieve all records from the FAZZRO_COMPANY table then we will use the SELECT statement to receive all records from the FAZZRO_COMPANY temporary table for the output result set.

We hope that you have understood the subtopic “MariaDB Create Temporary Table From Select Without Duplicates” by using the MariaDB CREATE TEMPORARY TABLE statement and the SELECT statement to create a temporary table from the existing table by the query. For a better acquaintance, we have used a sample example and defined it in deepness.

MariaDB Create Temporary Table From Select Year

In this MariaDB subtopic tutorial, we will learn and understand how to create a temporary table from the SELECT statement with the YEAR function which will help to create a temporary table from the existing table by the query, which will be explained with the help of a demonstrated example.

EXAMPLE:

CREATE TEMPORARY TABLE USA_HOPKINS_HOSPITAL
SELECT PATIENT_FIRSTNAME,PATIENT_LASTNAME, YEAR(PATIENT_ADMITDATE) AS YEAR_VALUE
FROM JOHNS_HOPKINS_HOSPITAL
WHERE PATIENT_ID>=8;

SELECT * FROM USA_HOPKINS_HOSPITAL;

In the aforementioned query, we have used the CREATE TEMPORARY TABLE statement to create a temporary table called USA_HOPKINS_HOSPITAL on the existing table as JOHNS_HOPKINS_HOSPITAL table.

Then we used the SELECT statement to retrieve all records of the PATIENT_FIRSTNAME and PATIENT_LASTNAME columns from the JOHNS_HOPKINS_HOSPITAL table with the WHERE condition.

In the YEAR function, it will extract the year portion value from the PATIENT_ADMITDATE columns on the JOHNS_HOPKINS_HOSPITAL table.

In the WHERE condition, the PATIENT_ID column is used with the GREATER THAN or EQUAL TO operator to find a value greater than or equal to 8 from the JOHNS_HOPKINS_HOSPITAL table. If the SELECT statement retrieves all records from the JOHNS_HOPKINS_HOSPITAL table only when the WHERE condition gets a TRUE value otherwise vice-versa.

This means that the SELECT statement execution of the existing table as the JOHNS_HOPKINS_HOSPITAL table will retrieve all records and transfer them to the USA_HOPKINS_HOSPITAL table.

If we want to check and retrieve all records from the USA_HOPKINS_HOSPITAL table then we will use the SELECT statement for the output result set.

We hope that you have understood the subtopic “MariaDB Create Temporary Table From Select Year” by using the MariaDB CREATE TEMPORARY TABLE statement on the table by the query. We have used an illustrated example and defined it in deepness, for a better explanation.

MariaDB Create Temporary Table From Select Yesterday

By utilizing the MariaDB CREATE TEMPORARY TABLE and SELECT statement to build a temporary table from the existing table by the query, which we’ll present with the help of an illustrated example, we will learn and comprehend the subtopic “MariaDB Create Temporary Table From Select Yesterday.”

EXAMPLE:

CREATE TEMPORARY TABLE JH_HOSPITAL
SELECT PATIENT_FIRSTNAME,PATIENT_LASTNAME, PATIENT_EMAIL,
DATE_ADD(PATIENT_DISCHARGEDATE, INTERVAL -1 DAY) AS YESTERDAY_VALUE
FROM JOHNS_HOPKINS_HOSPITAL
WHERE PATIENT_ID>15;

SELECT * FROM JH_HOSPITAL;

As we see in the overhead query, we have created a temporary table is created called JH_HOSPITAL from the existing table as the JOHNS_HOPKINS_HOSPITAL table by using the CREATE TEMPORARY TABLE statement.

Then we used the SELECT statement to retrieve all records from the PATIENT_FIRSTNAME, PATIENT_LASTNAME, and PATIENT_EMAIL columns from the JOHNS_HOPKINS_HOSPITAL table. In the DATE_ADD function, it will subtract 1 day from the PATIENT_DISCHARGEDATE columns from the JOHNS_HOPKINS_HOPSITAL table.

And to shorter the function_name, we have used the ALIAS clause with the AS keyword and given the name as YESTERDAY_VALUE column for the output result set. In the WHERE condition, the PATIENT_ID column is used with the GREATER THAN operator to find a value greater than 15 from the JOHNS_HOPKINS_HOSPITAL table.

If the WHERE condition turns out to be TRUE then the SELECT statement will retrieve all records from the JOHNS_HOPKINS_HOSPITAL table otherwise vice-versa.

The main purpose of the SELECT statement on the existing table as JOHNS_HOPKINS_HOSPITAL table will transfer the new records into the temporary table as JH_HOSPITAL temporary table. If we want to receive all records from the JH_HOSPITAL temporary table then we will use the SELECT statement.

We hope that you have understood the subtopic “MariaDB Create Temporary Table From Select Yesterday” by using the MariaDB CREATE TEMPORARY TABLE statement to create a temporary table from the existing table by the query.
