I am getting an error:

PAYROLL TEST.EMPLOYEE is mutating, trigger/function may not see it ORA-0651: at "PAYROLL TEST.TRIG_BIUD_EMP_TIME",line 6

Anyone have suggests how to correct this error?

The trigger is:

CREATE OR REPLACE TRIGGER "PAYROLL TEST"."TRIG_BIUD_EMPLOYEE" 
AFTER INSERT OR 
DELETE OR 
UPDATE OF "ID" 
ON "PAYROLL TEST"."EMPLOYEE" 
FOR EACH ROW 
DECLARE RecordCount NUMBER;

/* CASCADE UPDATES TO Pay Rate History */

SET pay_rate.employeeID = :new.id 
WHERE pay_rate.employeeID = :old.id; 

/* CASCADE UPDATES TO Employee Future Activities */ 
UPDATE emp_future 
SET emp_future.employeeID = :new.id 
WHERE emp_future.employeeID = :old.id; 

/* CASCADE UPDATES TO Employee History Info */

END IF;

IF RecordCount > 0 
THEN

END IF;
