In the image below we see where we create our example table named tbl Trigger Test with a primary key column named pk ID, a date column named Order Approval Date Time and a varchar column named Order Status.We populate the table with three test records with the Order Approval Date Time set to NULL and the Order Status set to "Pending".If specified, the trigger fires whenever occurs in the current database.ALL SERVER Applies to: SQL Server 2008 through SQL Server 2017.select * from employee24; EMP_ID ---------- E_NAME ---------------------------------------------------------------------------- SAL ---------- 1001 mike 12000 1002 jake 13000 EMP_ID ---------- E_NAME ---------------------------------------------------------------------------- SAL ---------- 1003 made 14000 [email protected]; Trigger created Update employee24 set sal=sal 1000 where emp_id=1002; 1 ROW Updated -------- -------- -------- | emp_id | ename | salary | -------- -------- -------- | 1002 | jake | 14000 | -------- -------- -------- In the above example, the trigger is created for employee24 table, and in the employee24 table, update operation is performed on the salary of an employee by setting sal=sal 100 where emp_id=1002. Salary=15000; END IF; END; / Trigger created sql UPDATE Employee01 SET Salary=500; Query OK, 5 rows affected (0.04 sec) Rows matched: 7 Changed: 5 Warnings: 0 sql select * from employee01; -------- ---------- ----------- ------------------- -------- ------- | emp_id | emp_name | city | designation | salary | perks | -------- ---------- ----------- ------------------- -------- ------- | 1 | david | delhi | manager | 10000 | 855 | | 2 | shaha | mumbai | assistant manager | 10000 | 853 | | 3 | sha | puna | scales manager | 10000 | 850 | | 4 | jack | bangalore | designer | 10000 | 854 | | 5 | james | mangalore | web designer | 10000 | 1124 | | 6 | mike | chennai | develpoer | 10500 | 840 | -------- ---------- ----------- ------------------- -------- ------- 6 rows in set (0.00 sec)CREATE TRIGGER student_insert AFTER insert ON student_table FOR EACH ROW BEGIN INSERT into student_log1(user_id,description) VALUES (user(), CONCAT('INSER T student records',new.stu_id,' ',new.stu_name,' ',new.stu_class)); END$$ Query OK, 0 rows affected (0.15 sec) sql select * from student_log1; ---------------- --------------------------------- | user_id | description | ---------------- --------------------------------- | [email protected] | INSERT student records1 mike 10 | | [email protected] | INSERT student records2 mad 20 | | [email protected] | INSERT student records3 mack 30 | ---------------- --------------------------------- 3 rows in set (0.00 sec)In the above example, after insert trigger will fire the condition after inserting a record inside the table or on the table i.e, after creating student_insert table it will fire on the student_log1 table and all the values will be displayed in the student_log1 table which was inserted in the student_table.

And, it has updated only one row based on the emp_id. CREATE TRIGGER stu_update AFTER UPDATE ON stu_table FOR EACH ROW BEGIN INSERT into stu_log(user_id, description) VALUES (user(), CONCAT('Update Student Record (',old.stu_id,' ',old.stu_name,' ',old.stu_class, ') to (',new.stu_id,' ',new.stu_name,' ',new.stu_class,')')); END; / sql select * from student_table02; -------- ---------- ----------- | stu_id | stu_name | stu_class | -------- ---------- ----------- | 1 | david | 9 | | 2 | shah | 9 | | 3 | mike | 9 | | 4 | james | 9 | -------- ---------- ----------- 4 rows in set (0.00 sec) sql select * from student_table02; -------- ---------- ----------- | stu_id | stu_name | stu_class | -------- ---------- ----------- | 1 | david | 10 | | 2 | shah | 10 | | 3 | mike | 10 | | 4 | james | 10 | -------- ---------- ----------- 4 rows in set (0.00 sec) sqlselect * from stu_log02; ---------------- -------------------------------------------------------- | user_id | description | ---------------- -------------------------------------------------------- | [email protected] | Update Student Record (1 david 9) to (1 david 10) | | [email protected] | Update Student Record (2 shah 9) to (2 shah 10) | | [email protected] | Update Student Record (3 mike 9) to (3 mike 10) | | [email protected] | Update Student Record (4 james 9) to (4 james 10) | ---------------- -------------------------------------------------------- In the above example, after update trigger will fire the condition after performing the update operation on a record inside the table or on the table.After selecting all records in the table, notice how the Order Approval Date Time for the second row does not equal the Order Approval Date Time for the first row.Again, this is our desired behavior and all appears well.These events primarily correspond to Transact-SQL CREATE, ALTER, and DROP statements, and certain system stored procedures that perform DDL-like operations.Logon triggers fire in response to the LOGON event that is raised when a user's session is being established. A trigger is a special type of stored procedure that automatically executes when an event occurs in the database server.
