I have an sql table that consist of three key constraints
Policy_Nbr, Trans_CodeOrig, Trans_Eff_Date. Now I need to create a stored procedure that will handle
violations on the table. What I mean here is that the old values(three key constraints) when I do an update on the table should
be included in the stored procedure. I must add them in. Here is the stored procedure I am working on.
Now I am need to include three parameters.
ExecOnTransOverride.upd(dr.Item(1), dr.Item(2), dr.Item(3), dr.Item(4), dr.Item(5), dr.Item(6), dr.Item(8), dr.Item(7), DateTime.Now, dr.Item(7), dr.Item(9),
oldPolicyNumber, oldTransCode, oldTransEffDate)
************ ********** ************

CREATE PROCEDURE dbo.prc_TransOverride_upd
(
@Policy_Nbr varchar(7),
@Trans_CodeOrig varchar(6),
@Trans_Eff_Date datetime,
- Three parameters added here
---------------------------------------------------
@Policy_Nbr_Old varchar(7),
@Trans_CodeOrig_Old varchar(6),
@Trans_Eff_Date_Old datetime,
---------------------------------------------------
@Override_Code varchar(2),
@NR_CodeOvr varchar(1),
@Trans_CodeOvr varchar(6),
@CreatedDate datetime,
@CreatedUID nvarchar(48),
@ModifiedDate datetime,
@ModifiedUID nvarchar(48),
@Plan_Year int
)

BEGIN
DECLARE @Err Int

UPDATE [TransOverride]
Set
[Policy_Nbr] = @Policy_Nbr,
[Trans_CodeOrig] = @Trans_CodeOrig,
[Trans_Eff_Date] = @Trans_Eff_Date,
[Override_Code] = @Override_Code,
[NR_CodeOvr] = @NR_CodeOvr,
[Trans_CodeOvr] = @Trans_CodeOvr,
[CreatedDate] = @CreatedDate,
[CreatedUID] = @CreatedUID,
[ModifiedDate] = @ModifiedDate,
[ModifiedUID] = @ModifiedUID,
[Plan_Year] = @Plan_Year
WHERE
[Policy_Nbr] = @Policy_Nbr AND
[Trans_CodeOrig] = @Trans_CodeOrig AND
[Trans_Eff_Date] = @Trans_Eff_Date
--------------- Now I must add these three parameters in my where clause so the update does not violate
--------------- the key constraints on the table. See below table for reference.
Set @Err = @@Error

RETURN @Err

passing the parameters.

Any help guys would be a thumbs up!
