SQL語句中將字符串轉換爲時間格式

字符串  datetext="2005-10-10"

SQL Server/MYSQL中：
cast('2005-10-10' as datetime)
如：select * from cds where zno = "+list+" and ChnNo = "+list2+" and RecDate= cast(' "+datetext+" ' as datetime) order by rdt

ORACLE中：
to_date('2005-10-10')
如：select * from cds where zno = "+list+" and ChnNo = "+list2+" and RecDate= to_date(' "+datetext+" ','yyyy-mm-dd') order by rdt

ACCESS中：
select * from cds where zno = "+list+" and ChnNo = "+list2+" and RecDate= #"+datetext+"# order by rdt
