使用javascript的数组来计算，代码如下：
复制代码 代码如下:
use tempdb go if (object_id ('fn_getArray' ) is not null ) drop function dbo . fn_getArray go create function fn_getArray (@ inStr1 varchar (8000 ), @ inStr2 varchar (8000 )) returns varchar (8000 ) as begin declare @ str varchar (8000 ) set @ str = ' var a = [''' + replace (@ inStr1 , ',' , ''',''' )+ ''']; var b = [''' + replace (@ inStr2 , ',' , ''',''' )+ ''']; var c="" for (var i=0;i<a.length;i++) { for (var j=0;j<b.length;j++) { if(a[i]==b[j]&&c.indexOf(a[i])<0) c+=a[i]+"," } } ' declare @ object int declare @ r varchar (800 ) exec sp_OACreate 'MSScriptControl.ScriptControl' , @ object output exec sp_OASetProperty @ object , 'Language' , 'javascript' exec sp_OAMethod @ object , 'eval' , @ r out , @ str return @ r end go select dbo . fn_getArray ('abc,dced,f23e,gew432' , '23c,abc,f23e,geafd,ged' ) /* 输出 abc,f23e, */
