Question

i have a question how to use an alias from a select query:

$timecheck = $db->query("SELECT DOE <= NOW() AS trigger FROM table WHERE a='$a'");
                if ($trigger != 0){
                    do  something
            }

is this the right way to use an alias? i need the alias trigger to check for a validation of a timestamp period. if that period is 0 or less means ‘trigger’ will output 1. in case of that another query should be performed.

so i hope my question is clear enough. i would really appreciate if there is someone who could help. thanks alot.

Answer 1

I think “trigger” may be a reserved word. Try:

$timecheck = $db->query("SELECT (DOE <= NOW()) AS trggr FROM table WHERE a='$a' ");
$trggr = //getting the value
if ($trggr != 0){
    // something
}
