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
