比较MySQL表php中设置的两个值

Question

I have a mysql table that has 2 columns, claim_status and show (both VARCHAR(500)) I tested with int didn't work.

I want to query only the items that have claim_status='0' and show='1'

right now nothing is returned here is my PHP code:

$query  = "SELECT COUNT(*) as num FROM $tableName WHERE claim_status='0' AND show='1'";
$query1 = "SELECT * FROM $tableName WHERE claim_status='0' AND show='1'";

** it fails on this line ** $query = "SELECT COUNT(*) as num FROM $tableName WHERE claim_status=0 AND show=1";

Answer 1

 $query = SELECT * FROM tablename WHERE claim_status='0' AND show='1'; 
    $result =  mysql_query($query);
if (!$result) {
    die('Invalid query: ' . mysql_error());
}
