I hope you won't mind helping me here: (I have searched the Postgres mailing lists but no-one seems to have had this problem) None of the documentation seems to address this:
Is this legal?
$sSql = "select glatype, gla.glacode, gladescrip, gladepr, gll.*
from gll,gla
where gll.glacode = gla.glacode
and gla.glatype = '".strtoupper($glrowresult)."'
and gll.fisyear = $year
order by gll.glacode";
$result1 = pg_exec($conn, $sSql);
for($i=0;$i<pg_numrows($result1);$i++)
{
$glresult = pg_fetch_array($result1,$i);
if($glresult["glatype"]=="FA")
{
$sSql="select * from gll
where gll.glacode = '".strtoupper($glresult["gladepr"])."'
and gll.fisyear = $year";
from gll,gla
where gll.glacode = gla.glacode
and gla.glatype = '".strtoupper($glrowresult)."'
and gll.fisyear = $year
order by gll.glacode";
$result1 = pg_exec($conn, $sSql);
for($i=0;$i<pg_numrows($result1);$i++)
{
$glresult = pg_fetch_array($result1,$i);
if($glresult["glatype"]=="FA")
{
$sSql="select * from gll
where gll.glacode = '".strtoupper($glresult["gladepr"])."'
and gll.fisyear = $year";
The second select does not work - it gives no error message either. I wonder if it does not like selecting a seond time from gll while in the loop after the first select. The idea is that some gl accounts need to refer to other ones for a calculation to be done during this report I am trying to do.
Thanks
