Right, Why would WHERE 1 return only 1 record? That makes no sense
and, no offense, it sounds like you really don't know where you're
talking about.

WHERE 1 is just a useless statement, but in his case makes it easier
to concatenate multiple "AND ..." statements.

As to the original problem, I guess that there might be something
wrong with your code later on that parses the result? Did you try to
use echo mysqli_num_rows($result1), just after the query to see how
many rows it returned?
