UPRAVIT
Dobře, máte problém ve vašich aktualizovaných dotazech. Oba případy příkazu If by měly vrátit stejný datový typ výsledku, takže když se pokoušíte přetypovat hodnoty data zpět na numerické, váš skutečný případ vrátí varchar pole datového typu, které je TOTAL a pole else vrátí numeric zadejte pole, takže to způsobí chybu.
Chcete-li to vyřešit, musíte odstranit prohlášení o případu, pak by to fungovalo správně podle vašich potřeb.

Nyní se tedy musíte smířit s hodnotami null ve sloupcích data. Doufám, že to odpoví na vaše pochybnosti.
Doufám, že to pomůže......
