oracle中translate用法 oracle如何判断数字字串中是否含有英文字母?
oracle如何判断数字字串中是否含有英文字母?
简单的:一条语句搞定,SqlPlus里面selectdecode(length(replace(translate("字符串的值","0123456789.",""),"","")),0,"isnumber","isnotanumber")fromdual麻烦点的:写function在oracle数据库中,createorreplacefunctionf_str_or_num(strvarchar2)returnvarchar2is2v_numnumber3v_returnvarchar2(60)4begin5v_num:=to_number(str)6v_return:=str||"isanumberstring!"7returnv_return8exceptionwhenothersthen9v_return:=str||"isnotanumberstring!"10returnv_return11endf_str_or_num然后调用selectf_str_or_num("字符串的值)fromdual
Oraclesql函数replace和translate的区别?
函数用法都不一样,translate是逐个字符替换的--包含ABC则替换为123SELECT REPLACE("AbCaBc","ABC","123") FROM dual--将A替换成1,B替换成2,C替换成3SELECT TRANSLATE("AbCaBc","ABC","123") FROM dual
oracle中调用存储过程时显示该存储过程处于无效状态是怎么回事?
1.你可以选择在过程里面加入record,定义一个类型type1,然后把你的数据插入这个类里面,通过for循环 调用type1(i)里面的数据2.你可以参考我的这个做法:select listagg(a,",") within group(order by a) from (select """"""||a||""""""a from (select regexp_substr("1,2,3,4,5","[^,]",1,level) a from dual connect by level <=length(translate("1,2,3,4,5",","||"1,2,3,4,5",",")) 1))。你把变量替换成你的需求数字列。
