This way is more efficient that doing the 'select count(*)' as
it's done from the same select query, and it also means that yo

Dear Dan,
I don't know if I understood what you really want. Therefore I will try to help, ok.
I use Postgres as Database.
You can find out how many rows have in a table after you run a SQL like this.
#!/usr/bin/perl
use Pg;
$db= Pg::connectdb(dbname=database);
# This

-- my table ---
row # : id , myid2 , myid3

row 3 : 3 , item 5 , item 6
row 4 : 4 , item 7 , item 8

#!/usr/bin/perl
use Pg;
$db= Pg::connectdb(dbname=database);
open (FILE, /var/log/file.log);
$result = $db-exec(SELECT * FROM table;);
for($i=0;$i$result-ntuples;$i++) {
$id =
