  • 0

I have the following code:

$SQL = "UPDATE jobs
        SET read = '1'
        WHERE id = '$job_id'";

$STH = $DBH->prepare($SQL);
$STH->execute();

read is a field in the table with a data type of BIT. The current data inside this field is 0 (false), and I’m trying to change it to 1 (true). However, I am getting this error:

Message: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘read = ‘1’ WHERE id = ’25” at line 2

I can’t see any syntax errors, so what is the problem?
