SQLServer中求两个字符串的交集

使用javascript的数组来计算，代码如下：
<div class="codetitle"><a style="CURSOR: pointer" data="14573" class="copybut" id="copybut14573" onclick="doCopy('code14573')"> 代码如下:<div class="codebody" id="code14573">
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,geafd,ged' )
/ 输出
abc,
/
