SQL Server Trigger to Increment Id

Here we will learn and understand how to use the SQL Server TRIGGER to increment the ID of the table’s column by the query, which is explained with the help of an illustrated example.

EXAMPLE:

USE SQLSERVERGUIDES;

CREATE TRIGGER AFTER_INCREMENT
ON CANADA_STATES
AFTER INSERT 
AS
UPDATE CANADA_STATES
SET STATE_ID=STATE_ID +10;

INSERT INTO CANADA_STATES
VALUES(68,'Jennifer Lawerence','Manitoba',22103);

SELECT * FROM CANADA_STATES
WHERE STATE_ID>=70;

In the aforementioned query, a trigger is created called AFTER_INCREMENT on the CANADA_STATES table by using the CREATE TRIGGER statement. Then we have used the AFTER trigger on the INSERT statement which means that once the AFTER trigger is fired then the DML STATEMENT will be triggered. Then the SQL STATEMENT which is used inside the CREATE TRIGGER statement will be executed.

The INSERT INTO statement will insert a new record into the CANADA_STATES table.

In the AS clause, the UPDATE statement has been used to update and add 10 values in the STATE_ID column in the CANADA_STATES table. It will add 10 values for each row in the STATE_ID column.

If we want to check it, the SELECT statement has been used to retrieve all records from the CANADA_STATES table with the WHERE condition. In the WHERE condition, the STATE_ID column is used with the GREATER THAN or EQUAL TO operator to find a value greater than or equal to 70 from the CANADA_STATES table.

If the WHERE condition turns out to be TRUE then the SELECT statement will retrieve all records from the CANADA_STATES table. But if the SELECT statement gets executed then it will retrieve the empty record set from the CANADA_STATES table only when the WHERE condition turns out to be FALSE.

SQL Server Trigger to Increment Id by 2

We will learn and understand how to use the SQL Server TRIGGER to increment ID by 2 of the column in the table by the query, which will be explained with the help of an illustrated example.

EXAMPLE:

USE SQLSERVERGUIDES;

CREATE TRIGGER AFTER_INSERT
ON USA_STATES
AFTER INSERT 
AS
UPDATE USA_STATES
SET STATE_ID=STATE_ID +2;

INSERT INTO USA_STATES
VALUES(32,'Alabama',22103,'Robin Anthony','Male');

SELECT * FROM USA_STATES
WHERE STATE_ID>=20
ORDER BY STATE_ID ASC;

As we see in the above query, a trigger is created called AFTER_INSERT on the USA_STATES table by using the CREATE TRIGGER statement. Then we have used the AFTER trigger on the INSERT statement which means that once the AFTER trigger is fired then the INSERT statement will be triggered and in reflection, the SQL STATEMENT will be executed to show the result set.

In the INSERT statement, it will insert a new record into the USA_STATES table once the AFTER trigger is fired.

In the AS clause, the UPDATE statement is used to update and set a numeric_value for all records of the STATE_ID column by adding the 2 in the USA_STATES table. This means that all records of the STATE_ID column will be updated and added by 2 from the USA_STATES table.

If we want to check all records of the USA_STATES table have been updated. Then we used the SELECT statement to retrieve all records from the USA_STATES table with the WHERE condition. In the WHERE condition, the STATE_ID column is used with the GREATER THAN or EQUAL TO operator to find a value greater than or equal to 20 in the USA_STATES table.

And we have also used the ORDER BY clause to arrange the STATE_ID column in ascending order by using the ORDER BY expression ASC.

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

SQL Server Trigger to Increment Id After Insert

Here we will learn and understand how to use SQL Server AFTER trigger with the INSERT statement to increment ID column of the table by the query, which will be explained with the help of an illustrated example.

EXAMPLE:

USE SQLSERVERGUIDES;

CREATE TRIGGER AFTER_INSERT
ON CANADA_STATES
AFTER INSERT
AS
BEGIN
UPDATE CANADA_STATES
SET STATE_ID=STATE_ID+1
END;

INSERT INTO CANADA_STATES
VALUES(79,'Vin Disesl','British Columbia',51208);

SELECT * FROM CANADA_STATES
WHERE STATE_ID>=75;

As we see in the above query, we have created a trigger called AFTER_INSERT on the CANADA_STATES table by using the CREATE TRIGGER statement. Then we used the AFTER trigger on the INSERT statement which means that once the AFTER trigger is fired then the DML STATEMENT will be triggered. This means that the SQL STATEMENT will be executed for the result set.

In the INSERT INTO statement, it will insert a new record into the CANADA_STATES table once the AFTER trigger is fired. In the BEGIN statement, the UPDATE statement is used to update and set a new value by 1 for all records of the STATE_ID column in the CANADA_STATES table. To end the trigger, we have used the END statement.

To check the new value of the STATE_ID column has been updated or not in the CANADA_STATES table. In the SELECT statement, it will retrieve all records from the CANADA_STATES table with the WHERE condition.

In the WHERE condition, the STATE_ID column is used with the GREATER THAN or EQUAL TO operator to find a value greater than or equal to 75 from the CANADA_STATES table.

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

SQL Server Trigger to Increment ID And Value

Here we will learn and understand how to use the SQL Server TRIGGER to increment ID and value of the table by the query. And which will be explained with the help of an illustrated example.

EXAMPLE:

USE SQLSERVERGUIDES;

CREATE TRIGGER AFTER_INCREMENTID
ON USA_STATES
AFTER INSERT 
AS 
BEGIN
UPDATE USA_STATES
SET STATE_ID=STATE_ID+1,
STATE_NAME='Florida'
WHERE STATE_ID=31
END;

INSERT INTO USA_STATES
VALUES(34,'Delaware',54120,'Chris Evans','Male');

SELECT * FROM USA_STATES
WHERE STATE_ID >=28
ORDER BY STATE_ID ASC; 

In the aforementioned query, we have created a trigger called AFTER_INCREMENTID on the USA_STATES table by using the CREATE TRIGGER statement. Then the AFTER trigger is fired and the INSERT statement will be triggered. After the SQL STATEMENT which is used inside the CREATE TRIGGER statement will be executed.

In the INSERT INTO statement, it will insert a new record into the USA_STATES table once the AFTER trigger is fired.

In the BEGIN statement, the UPDATE statement is used to update and set a new value of the STATE_ID column by adding 1 for all records in the CANADA_STATES table. And also updated the string_name of the STATE_NAME column as Florida with the WHERE condition. In the WHERE condition, the STATE_ID column is used with the EQUAL TO operator to find a value equal to 31 from the CANADA_STATES table.

If the WHERE condition turns out to be TRUE then the UPDATE statement will update the new value of the STATE_ID and STATE_NAME columns in the CANADA_STATES table. But if the UPDATE statement is executed successfully only when the WHERE condition turns out to be TRUE.

If we want to check the trigger is executed on the INSERT and UPDATE statement. Then we have to use the SELECT statement for the result set. The execution of the SELECT statement says:

  • The SELECT statement retrieves all records from the USA_STATES table with the WHERE condition. In the WHERE condition, the STATE_ID column is used with the GREATER THAN or EQUAL TO operator to find a value greater than or equal to 28 from the USA_STATES table. And also arranged the STATE_ID column in ascending order by using the ORDER BY expression ASC.
  • If the SELECT statement retrieves all records from the USA_STATES table only when the WHERE condition turns out to be TRUE.
  • But if the SELECT statement gets executed successfully and retrieves an empty record set from the USA_STATES table only when the WHERE condition turns out to be a FALSE value.

SQL Server Trigger to Increment ID And Decimal

In this SQL Server section, we will learn and understand how to use SQL Server TRIGGER to increment ID on the table by the query, which will be explained with the help of an illustrated example.

EXAMPLE:

USE SQLSERVERGUIDES;

CREATE TRIGGER AFTER_ROUND
ON USA_STATES
AFTER INSERT 
AS 
BEGIN
UPDATE USA_STATES
SET STATE_ID=STATE_ID+1,
STATE_ZIPCODE=ROUND(54120,2)
WHERE STATE_ID=32
END;

INSERT INTO USA_STATES
VALUES(33,'Delaware',12050,'Anthony Sins','Male');

SELECT * FROM USA_STATES
WHERE STATE_ID>=28
;

As we see in the above query, a trigger is created called AFTER_ROUND on the USA_STATES table by using the CREATE TRIGGER statement. Then we have used the AFTER trigger on the INSERT statement which means that once the AFTER trigger is fired then the INSERT statement will be triggered and make an effect on the USA_STATES table.

Then the SQL STATEMENT which is used inside the CREATE TRIGGER statement will be executed and show the result set for the output. In the INSERT INTO statement, it will insert new records from the USA_STATES table after the trigger is fired.

In the UPDATE statement, it will update and set a new value of the STATE_ID column by adding 1 in all records of the USA_STATES table. And we also updated the USA_ZIPCODE column by using the ROUND function. The ROUND function will round off decimal by an integer as per the number in the USA_ZIPCODE column in the USA_STATES table.

If the WHERE condition turns out to be TRUE then the UPDATE statement will update and set a new value for both columns in the USA_STATES table otherwise vice-versa.

If we want to check the trigger execution of the USA_STATES table then we will use the SELECT statement execution. Here the execution of the USA_STATES table says:

  • The SELECT statement retrieves all records from the USA_STATES table which is used with the WHERE condition. In the WHERE condition, the STATE_ID column is used with the GREATER THAN or EQUAL TO operator to find a value greater than or equal to 28 from the USA_STATES table.
  • If the WHERE condition turns out to be TRUE then the SELECT statement retrieves all records from the USA_STATES table otherwise vice-versa.

SQL Server Trigger to Increment ID And Last Value

We will learn and comprehend how to use SQL Server TRIGGER in this SQL Server section so that the query can increment the table’s ID and Last Value and that will be clarified with the aid of an example.

EXAMPLE:

USE SQLSERVERGUIDES;

CREATE TRIGGER AFTER_LASTID
ON CANADA_STATES
AFTER INSERT 
AS 
BEGIN
UPDATE CANADA_STATES
SET STATE_ID=STATE_ID +1
WHERE STATE_ID =(SELECT MAX(STATE_ID) FROM CANADA_STATES)
END;

INSERT INTO CANADA_STATES
VALUES(85,'David William','British Columbia',630);

SELECT * FROM CANADA_STATES
WHERE STATE_ID = (SELECT MAX(STATE_ID) 
FROM CANADA_STATES)

Using the CREATE TRIGGER command, we have built a trigger on the CANADA_STATES table called AFTER_LASTID in the aforementioned query. When the AFTER trigger fires, the DML STATEMENT will then be activated and executed on the CANADA_STATES table because the AFTER trigger was used on the INSERT statement. Once the event has occurred, the SQL STATEMENT used in the CREATE TRIGGER statement will be performed.

The trigger was fired, and the INSERT INTO statement was used to add a new record to the CANADA_STATES table.

In the BEGIN statement, the UPDATE statement is used to update and set a new numeric value of the STATE_ID column by adding 1 to all records of the CANADA_STATES table. In the WHERE condition, the STATE_ID column is used with the EQUAL TO operator.

With the EQUAL TO operator, the SELECT statement is used to retrieve the max value of the STATE_ID column in the CANADA_STATES table by using the MAX function. To close the trigger execution, we have to end by using the END statement.

The UPDATE statement will be run and no value will be modified based on the CANADA_STATES table’s WHERE condition, if the WHERE condition proves to be FALSE. But if the WHERE condition receives a TRUE answer, the UPDATE statement updates all records of the STATE_ID column by adding 1, which is dependent on the WHERE condition.

If we want to check the UPDATE and INSERT statement has been executed by using the AFTER trigger on the CANADA_STATES table. Here the execution of the SELECT statement says:

  • The SELECT statement retrieves all records from the CANADA_STATES table with the WHERE condition. In the WHERE condition, the STATE_ID column is used with the EQUAL TO operator to find a value with the subquery.
  • In the subquery, the SELECT statement is used with the MAX function to find a max value of the STATE_ID column in the CANADA_STATES table.
    • If the WHERE condition turns out to be TRUE then the SELECT statement will retrieve all records from the CANADA_STATES table.
    • But if the SELECT statement gets executed and retrieves an empty record set from the CANADA_STATES table only when the WHERE condition gets a FALSE value.

SQL Server Trigger to Increment ID And Last Name

In this SQL Server subtopic tutorial, we will learn and understand how to use SQL Server TRIGGER to increment ID and Last Name Columns from the table by the query. And which will be explained with the help of an illustrated example.

EXAMPLE:

USE SQLSERVERGUIDES;

CREATE TRIGGER TRIGGER_INCREMENT
ON CANADA_STATES
AFTER INSERT
AS
BEGIN
UPDATE CANADA_STATES
SET STATE_ID=STATE_ID+0,
FULL_NAME='Dwayne Johnson'
WHERE STATE_ID=75
END;

INSERT INTO CANADA_STATES
VALUES(81,'Kevin Heart','Yukon',87119);

SELECT * FROM CANADA_STATES
WHERE STATE_ID>=75;

In the aforementioned query, a trigger is created called TRIGGER_INCREMENT on the CANADA_STATES table by using CREATE TRIGGER statement. Then we used the AFTER trigger on the INSERT statement which means that once the AFTER trigger is fired then the INSERT statement will be executed and make an effect on the CANADA_STATES table.

But in return, the SQL STATEMENT which is used inside the CREATE TRIGGER statement will be executed.

The INSERT statement will insert a new record into the CANADA_STATES table once the AFTER trigger is fired and events will be triggered for the SQL STATEMENT.

In the BEGIN statement, the UPDATE statement is used to update and set a new value of the STATE_ID column by 0. And we have updated the FULL_NAME column as Dwayne Johnson with the WHERE condition. In the WHERE condition, the STATE_ID column is used with the EQUAL TO operator to find a value equal to 75 from the CANADA_STATES table.

If the WHERE condition turns out to be TRUE then the UPDATE statement will update the new value of both columns in the CANADA_STATES table otherwise vice-versa.

If we want to check the INSERT and UPDATE statement has been executed successfully and has made an effect on the CANADA_STATES table. Here the execution of the SELECT statement says:

  • The SELECT statement is used to retrieve all records from the CANADA_STATES table with the WHERE condition. In the WHERE condition, the STATE_ID column is used with the GREATER THAN or EQUAL TO operator to find a value greater than or equal to 75 from the CANADA_STATES table.
    • If the WHERE condition turns out to be TRUE then the SELECT statement will retrieve all records from the CANADA_STATES table.
    • But if the SELECT statement gets executed successfully and retrieves an empty record set from the CANADA_STATES table only when the WHERE condition turns out to be a FALSE value.
