if kismispurchase.availableqty contains NULL value also then write in below way

isnull(kismispurchase.availableqty,0) <> 0 or also isnull(kismispurchase.availableqty,0) != 0

Good point about the NULL value, but that second statement is wrong ... != is not valid. You might want to remove it

I stand corrected about the "!=" ... that will teach me to use a more modern version of SQL Server. My apologies

hello....

your NOT Equal Condition Is Correct...you Can Use both Symblos

(!=,<>)

May be your Column "kismispurchase.availableqty" Contains null value than your query not return correct data so you can use ISNULL like this

$q1=("SELECT kismispurchase.km_id, kismispurchase.kpm_id,kismispurchase.lot_no as lot_no, kismispurchasemaster.Sdate as sdate FROM kismispurchase inner join kismispurchasemaster on kismispurchasemaster.kpm_id=kismispurchase.kpm_id and where isnull(kismispurchase.availableqty,0)!=0");

OR
$q1=("SELECT kismispurchase.km_id, kismispurchase.kpm_id,kismispurchase.lot_no as lot_no, kismispurchasemaster.Sdate as sdate FROM kismispurchase inner join kismispurchasemaster on kismispurchasemaster.kpm_id=kismispurchase.kpm_id and where isnull(kismispurchase.availableqty,0)<>0");
