我试图根据日期寻找亚洲开发银行的记录。 但是,搜查是以每月和年份为依据的。 i.emm/yyyyyy and dd is to be Wild-card.

我的问候是:

Select ucid, uc_name, From (UC_Table1)
where UC_Date like To_Date( 11/*/2011 , mm/dd/yyyy )

this gives me the following error: ORA-01858: a non-numeric character was found where a numeric was expected, So obviously it doesn t like * or % or _ or ? as wild-cards for dd.

问题回答

Wildcards do not work like that within a function. The To_Date() function parses out the * before the LIKE has a chance to see it. Consider:

SELECT ucid, uc_name
FROM UC_Table1
WHERE UC_Date >= To_Date( 11/01/2011 ,  mm/dd/yyyy )
   AND UC_Date < To_Date( 12/01/2011 ,  mm/dd/yyyy )
