Čištění telefonních čísel na serveru SQL Server
Vytvořte funkci serveru SQL Server, abyste zkontrolovali a vyčistili řetězec telefonního čísla na mezinárodní nebo britské úrovni
Kontext
Jednou z nejčastějších výzev, které na klientské infrastruktuře čelíme, jsou špatně formátovaná telefonní čísla. Mají tendenci se dostat do špatného stavu, když byly spuštěny pomocí aplikace Excel nebo různých jiných scénářů, které mění výstup.
Tato funkce je zaměřena na britská čísla s určitým rozsahem délek mezinárodních čísel. Mohlo by to být přizpůsobeno pro jakoukoli jinou oblast docela snadno úpravou prvních 6 položek případu v posledním příkazu případu a tři položky případu ve druhém posledním případu.
Toto se používá již řadu let a pomocí následujících kroků se zachránilo bezpočet telefonních čísel;
- Zálohujte číslo do dočasné proměnné
- Nahraďte počáteční znaménko dvojitou nulou
- Odeberte všechny zbývající textové znaky z řetězce
- Nahraďte britská telefonní čísla číslem 0
- Zkontrolujte délku každého typu čísla.
- Vraťte nové číslo nebo staré číslo, pokud jej nebylo možné ověřit.
