總覺(jué)得ACCESS-VBA中少了這么一個(gè)函數(shù),剛才既時(shí)寫(xiě)了一個(gè)請(qǐng)大家提出意見(jiàn):
'--------------------------------------------------------------------------------------------------------------
'名稱(chēng): 域更新函數(shù)
'功能: 同Dlookup等域函數(shù)
'參數(shù):
' 同Dlookup等域函數(shù),但Expr參數(shù)有點(diǎn)像Switch,以便更新多少字段.
' cn參數(shù)可以用來(lái)?行事??理
'用法:
' 1.先決條件:假如有表[BMB],且含有字段luoma,Int,ddate,check,mony
' 2.debug.Print DSet("luoma,aa,Int,3455,ddate,2009-9-9,check,-1,mony,5000 ","BMB","id=0")
'返回: True表示成功,False表示未成功或沒(méi)有更新
'日期: 2007-07-26
