Thread: pg_result

hi list.

this is my script:

$query7="select provinceid from province where province like '$tablename1';";
$result7=pg_exec($conn,$query7);
if(!$result7){
    .
    .
    .}
else    {
    .
    .
    .
    }

my problem is when the value of the variable $tablename1 is not on the table
province, it doesn't go to the if statements. what am i doing wrong?

thanks!

You need to test for the number of rows returned.  The $result7 is
simply true because the statement worked (it was syntactically correct)
even though no rows are returned.

if ( $result7 && pg_NumRows($result7) > 0 ) {
  ... process some rows ...
}
else {
  ... this might be an error ...
}

Hi,
    PLease look at the query.The syntax is

"SELECT attribute_name[,attr2,..] FROM tables WHERE attribute =[LIKE,IN,..] ETC..

It looks in ur query that province is an attribute as well as a query.
