Mam długi skrypt i lubię być w stanie uruchomić cały plik, gdy muszę i nie martwię się o to, czy części już zostały uruchomione. Ale poniższy skrypt daje mi problemy. Z jakiegoś powodu wychodzi poza instrukcję IF, nawet jeśli kolumny „EntityID” i „EntityType” nie istnieją, w którym to przypadku nie powinny przechodzić przez instrukcję IF. Czy ktoś może mi powiedzieć, co jest nie tak?

IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'Notes' AND COLUMN_NAME IN ('EntityId', 'EntityType'))
BEGIN
    BEGIN TRANSACTION
        --Delete notes where EntityType and EntityID are both NULL
        DELETE FROM [dbo].[Notes]
        WHERE [EntityId] = NULL 
        AND [EntityType] = NULL
        --Delete notes where the corresponding contact or account has been deleted.
        OR [ID] IN (9788, 10684, 10393, 10718, 10719)

        --Populate new columns with all existing data
        UPDATE [dbo].[Notes]
        SET [AccountId] = [EntityId]
        WHERE [EntityType] = 1

        UPDATE [dbo].[Notes]
        SET [ContactId] = [EntityId]
        WHERE [EntityType] = 2

        --Delete EntityId and EntityType columns from the Notes table
        ALTER TABLE [dbo].[Notes]
        DROP COLUMN [EntityId], [EntityType]
    COMMIT
END
GO
