if I Add new column at employee table which contains default value like
create table employee(empid [varchar](10),empname [varchar](50),salary [decimal](18, 2),status [varchar] (100)(default ''))
create table employeeHistory(EffectDate [datetime],empid [varchar](10),empname [varchar](50),salary [decimal](18, 2),status [varchar] (100)(default ''))
create trigger UpdateEmployee on employee
after update AS
begin
declare @empid as [varchar](10)
declare @empname as [varchar](50)
declare @salary as [decimal](18, 2)
declare @status as [varchar](100)
select @empid =d.empid from deleted d
select @empname =d.empname from deleted d
select @salary =d.salary from deleted d
if update(status)
select @status=i.statusfrom deleted i
else
begin
select @status=i.status from deleted i
update [employee]
set status='' where empid=@empid
end
Insert into employeeHistory([EffectDate],[empid],[empname],[salary],[status])
SELECT getdate(), empid, empname, salary,status
FROM deleted
end
Example: emp001 xxxx 10000.00 paid
emp002 yyyy 12000.00 paid
emp003 zzzz 10000.00 paid
emp004 aaaa 15000.00 paid
emp005 bbbb 12000.00 paid
emp006 cccc 12000.00 paid
emp007 pppp 10000.00 paid
update employee set salary =11000.00 where salary =10000.00
after update first updated row set its default value but rest rows don't set it in employee table. Please give me a solution at your earliest.
