Format Trigger:-Format trigger is noting but displaying the output dynamically based on condition.

By using this we can hide or display the data based on condition.

It returns Boolean

For that we are going to create report based on ‘EMP’ that, if ‘SAL’ is less than 1500 then that employeessalary need not to display else to display the employees with their salary which will shown step by stepprocess.

Now we are executing the report

Before that one’s we will the employees whose salary is less than 1500.

For that

SELECT * FROM emp;

From the above output we can say that employees with empno 7654, 7844, 7900,7744,7746,7747whose salary is less than or equal to 1500.

According to our report the employees whose salary is less than or equal to 1500 those employees salaryneed not to display.

Lets check.

Execute the Report

We get the output shown below
