Hi all,
I want to use transaction with my while loop program.
Because with per loop, I want to Update A Table and Insert B Table.

While @start <= @number
BEGIN
Update TableA SET fieldA1 = @valueA1, fieldA2 = @valueA2

Insert into TableB (fieldB1, fieldB2) values (@valueB1, @valueB2)
SET @start = @start + 1
END

How can I apply transaction with While loop?
Because if any error occur with once loop, I want to rollback previous Update and Insert statement.

Thank you very much.

BEGIN TRY
BEGIN TRANSACTION
While @start <= @number
BEGIN
Update TableA SET fieldA1 = @valueA1, fieldA2 = @valueA2

Insert into TableB (fieldB1, fieldB2) values (@valueB1, @valueB2)
END

COMMIT

END TRY

BEGIN CATCH

IF @@TRANCOUNT<>0
BEGIN
ROLLBACK
SELECT ERROR_MESSAGE()

END
END CATCH

PBUH
