Subject: Re: [SQL] Help with multistage query

 

I have a perl script that issues a series of SQL statements to perform some queries.  The script works, but I believe there must be a more elegant way to do this.

 

The simplified queries look like this:

 

SELECT id FROM t1 WHERE condition1;   ;returns about 2k records which are stored in @idarray

 

foreach $id (@idarray) {

   SELECT x FROM t2 WHERE id=$id;   ; each select returns about 100 records which are saved in a perl variable

}

how about

select t1.id from t1, t2 where t1.id = t2.id and t2.id = x
