How to debug a SQL Server Trigger statement is covered in this SQL Server tutorial. To assist you in better understanding the topic, we will debate and conclude several situations. The whole list of topics we’ll cover is given below.

How to debug an SQL Server Trigger

Here we will learn and understand how to debug an SQL Server Trigger by using the STORE PROCEDURE on the database’s table by the query, which will be explained with the help of an illustrated example.

In the IT industry, a developer loves the debugging process because they are useful when programs fail in a calculation otherwise it will return an error. Now, think about the TRIGGERS that perform complex operations silently.

How to stop Trigger in SQL Server

Here we will learn and understand how to stop triggers in SQL Server by the query and also by steps. And which will be explained with the help of an illustrated example.

Sometimes we need to temporarily disable the trigger for data recovery or troubleshooting purposes. The DISABLE TRIGGER statement must be used in this situation:

DISABLE TRIGGER [SCHEMA_NAME].[YOUR_TRIGGER_NAME]
ON [ OBJECT_NAME | DATABASE | ALL SERVER];

The syntax explanation:

• The trigger name that the schema name corresponds to must be specified first, followed by the name of the trigger that we want to disable using the DISABLE TRIGGER statement.
• Second, if the trigger is connected to a DML trigger, state the name of the table or view to which it was attached. If the trigger is a DDL database scoped trigger, we will use the DATABASE, and if it is a DDL server scoped trigger, we will use the SERVER.

Here’s an example of the DISABLE TRIGGER statement to disable a trigger in the SQL Server by the following query:

EXAMPLE:

DISABLE TRIGGER dbo.IFELSE_CONDITION
ON CANADA_STATES;

As we see in the above query, we have used the DISABLE TRIGGER statement to disable a trigger called IFELSE_CONDITION from the CANADA_STATES table.

Here are also some steps to be followed if we want to disable the trigger by mouse:

• First, use the CURRENT_DATABASE and minimize the DATABASE folder for it.
• Then, minimize the TABLES folder.
• Then go into the current table folder i.e; [CANADA_STATES] folder where the trigger is created.
• Click the TRIGGERS folder and minimize the folder.
• Click the TRIGGER_NAME as IFELSE_CONDITION trigger then click the DISABLE button.
• A dialogue box will open and then press the OK button.

We hope that you have understood the subtopic “How to stop trigger in SQL Server” by using the SQL Server DISABLE TRIGGER statement of the table by the query. For a better understanding, we have used an example and explained it in depth.

How to Trigger a Trigger in SQL Server

In this SQL Server subtopic section, we will learn and understand how to trigger a trigger in SQL Server, which will be explained with the help of points.

Here are some steps to be followed to trigger a trigger in SQL Server:

• First, navigate the TRIGGERS sub-folder from the TABLE folder.
• Second, select the trigger from the TRIGGERS folder that we want to DISABLE or ENABLE button for a trigger.
• Click on the ENABLE/ DISABLE to enable or disable the trigger by using the SQL Server Management Studio (SSMS).
• Disabling specific SQL Server triggers on a table using the T-SQL and enabling specific SQL Server triggers on a table using the T-SQL.

If we want to disable or enable a trigger from the SQL Server then follow the following query:

EXAMPLE:

ENABLE TRIGGER IFELSE_STATEMENT 
ON CANADA_STATES;

DISABLE TRIGGER IFELSE_STATEMENT
ON CANADA_STATES;

In the first query, we have used the ENABLE TRIGGER on the CANADA_STATES table to enable a trigger called IFELSE_STATEMENT. But if we want to disable the same trigger which is enabled then we have to use the DISABLE TRIGGER statement in exchange for the ENABLE TRIGGER statement from the CANADA_STATES table.

We hope that you have understood the subtopic “how to trigger a trigger in SQL Server” by using the ENABLE TRIGGER and DISABLE TRIGGER statement on the table by the query. For a better explanation, we have used an example and explained it in depth.

How to get Trigger in SQL Server

In this SQL Server section, we will learn and understand how to get triggered in SQL Server by following some steps in SQL Server Management Studio.

Here are some steps to be followed to get trigger in SQL Server:

• Simply connect to DATABASE ENGINE in the Object Explorer and expand its instantiation.
• First, expand the database that we want, develop tables, and then expand the table that contains the trigger for which we want to view the definition.
• Then expand the TRIGGER, right-click on the trigger we want and click the MODIFY button. The definition of the SQL Server TRIGGER will show on the query window.

We hope that you have understood how to get Trigger in SQL Server by following some steps given above. We have explained it in depth, for better understanding.
