DECLARE @a char (10), B @ BIGINT, BIGINT @ C, D @ char (10), E @ VARCHAR (10), @ DATE DATE, salary1 int @, @ salary2 int, int salary3 @, @ SA int
the begin
SET @ B = 3,000,000,001
SET @ @ C = B + (the SELECT COUNT (*) the FROM payroll record table)
SET A = @ Cast (AS @c char (10))
SET @e = (the CONVERT (VARCHAR (10), GETDATE (), 120))
SET DATE = @ Cast (@e AS VARCHAR (30))
SET @ D = (SELECT inserted The job number from)
SET @ SA = (SELECT employee salary from floor scale
where @ d = job number)
SET @ salary1 = (SELECT absenteeism days from inserted The) * 100
SET @ salary2 = (SELECT overtime number from days inserted The) * 50
SET @ salary3 = (@ SA) + @ salary2- @ salary1
INSERT payroll records into the table
