I want to save with Stored Procedure. Please check my script first
`USE [Payroll]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER Procedure [dbo].[ResignSave]
(
#ResignCode varchar(50),
#Nip Varchar(50),
#Keterangan Varchar(50),
#ResignDate Varchar(50),
#CreatedBy varchar(50),

#msg varchar(25) = NULL
)
AS
BEGIN
Begin Try
set #ResignCode = (select case
when right(max(ResignCode),7) is null then 'RC0000001'
else ('RC' + RIGHT('0000000' + cast(right(max(ResignCode),7) + 1 as nvarchar),7))
end ResignCode from Resign)
INSERT INTO Resign(ResignCode,Nip, Keterangan, ResignDate, CreatedBy,CreatedDate)
VALUES(#ResignCode,#Nip,#Keterangan, #ResignDate,#CreatedBy,GETDATE())
end try
Begin Catch
Select ERROR_NUMBER() as ErrorNumber, ERROR_MESSAGE() as ErrorMessage
End Catch
End

My Stored Procedure working fine. My question is, is there anyway to checking the input if it's exists in my table then set it to my #msg.

Answer 1

You might be looking for below code.
ALTER Procedure [dbo].[ResignSave]
(
#ResignCode varchar(50),
#Nip Varchar(50),
#Keterangan Varchar(50),
#ResignDate Varchar(50),
#CreatedBy varchar(50),
#CreatedDate date,
#msg varchar(25) = NULL
)
AS
BEGIN
Begin Try
if exists (select * from Resign where ResignCode = #ResignCode and Nip = #Nip and ResignDate = #ResignDate) then
BEGIN
set #msg = 'Record already exists'
select #msg AS ProcResult
END
set #ResignCode = (select case
when right(max(ResignCode),7) is null then 'RC0000001'
else ('RC' + RIGHT('0000000' + cast(right(max(ResignCode),7) + 1 as nvarchar),7))
end ResignCode from Resign)
INSERT INTO Resign(ResignCode,Nip, Keterangan, ResignDate, CreatedBy,CreatedDate)
VALUES(#ResignCode,#Nip,#Keterangan, #ResignDate,#CreatedBy,GETDATE())
SELECT 'Insert Successful' AS ProcResult
end try
Begin Catch
Select 'Insert Failed:' + cast(ERROR_NUMBER() as varchar) + ERROR_MESSAGE() AS ProcResult
End Catch
End
If this is what you are looking for, you don't need the #msg parameter. juts execute the procedure and get the returned result set
