SQLServer中求两个字符串的交集

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,
*/
