Dette er en af de få gange, at en markør faktisk er ideel i SQL Server. Her er en måde. Når du ser PRINT-erklæringen og er tilfreds, kan du kommentere den ud og fjerne de to linjer under den. Jeg tilføjede noget logik for at tilføje filnavnet og en behandlet dato, som normalt er nødvendig, men din tabeldefinition ville have brug for disse kolonner. Det burde få ideen igennem.
