How to run stored procedure query between 2 table & insert data base on reference column? - sql

Question

I've created a simple stored procedure to update my Sample_TAG_NUMBERTEST table but I need it to get an ItemCode from another table PartItem by using both SOLine & SONbr to do the query but I don't know how to write it.
2nd thing I need to do is when my StatusCode column is N001 then my DESC column will automatically insert NEW ORDER data value, for PR002 my DESC column will become Progress.
How can I do that? Thanks in advance.
ALTER PROCEDURE [dbo].[SampleTagNumberUpdate]
#sONbr nvarchar(50) = NULL,
#SOLine nvarchar(50) = NULL,
#SerialNbr nvarchar(50) = NULL,
#StatusCode nvarchar(50) = NULL,
#PackType nvarchar(50) = NULL,
#PalletID nvarchar(50) = NULL,
#PackingListNo nvarchar(50) = NULL,
#ItemCode nvarchar(50) = NULL,
#CrDateTime nvarchar(50) = NULL,
#CrUserID nvarchar(50) = NULL,
#return nvarchar(50) = NULL OUTPUT
AS
BEGIN
SET NOCOUNT ON;
IF EXISTS(SELECT sONbr , SOLine
FROM [SampleSystem].[dbo].[Sample_TAG_NUMBERTEST]
WHERE sONbr = #sONbr AND SOLine = #SOLine)
BEGIN
UPDATE [SampleSystem].[dbo].[Sample_TAG_NUMBERTEST]
SET SerialNbr = #SerialNbr
,StatusCode = #StatusCode
,PackType = #PackType
,PalletID = #PalletID
,PackingListNo = #PackingListNo
,ItemCode = #ItemCode
,LastUpdDateTime = GETDATE()
,LastUpdUserID = #CrUserID
WHERE sONbr = #sONbr AND SOLine = #SOLine
IF ##ERROR <> 0
Set #Return = 'UPDATE FAILED'
ELSE
Set #Return = 'UPDATE SUCCESSFULLY'
END
ELSE
BEGIN
INSERT INTO [SampleSystem].[dbo].[Sample_TAG_NUMBERTEST](SONbr, SOLine, SerialNbr
,StatusCode
,PackType
,PalletID
,PackingListNo
,ItemCode
,CrDateTime
,CrUserID)
VALUES(#sONbr, #SOLine, #SerialNbr, #StatusCode, #PackType
,#PalletID
,#PackingListNo
,#ItemCode
,GETDATE()
,#CrUserID)
IF ##ERROR <> 0
Set #Return = 'INSERT DATA FAILED'
ELSE
Set #Return = 'INSERT DATA SUCCESSFULLY'
END
END

Answer 1

I believe I have provided an example for both questions below:
UPDATE T
SET ItemCode = (SELECT PI.ItemCode FROM PartItem AS PI WHERE PI.SO = #SO AND PI.SO_LINE = #SO_LINE),
DESC = CASE #StatusCode WHEN 'N001' THEN 'NEW ORDER'
ELSE CASE #StatusCode WHEN 'PR002' THEN 'PROGRESS' ELSE '' END
END,
<other columns here...>
FROM SAMPLE_TAG_NUMBERTEST AS T
