SQL dotaz pro dynamické přidání fiskálního měsíce pomocí pivotu

K tomu budete muset použít dynamický SQL. hrubé kód bude podobný tomuto:

Můj návrh místo použití dočasné tabulky @FiscalMonth je vytvořit tabulku, která je pro to trvalá. Při použití dynamického sql bude mnohem jednodušší dotazovat se na perm tabulku než na dočasnou tabulku. Dočasná tabulka může být mimo rozsah dynamického dotazu.
