Question

Please I have a field in my data base with a type text, but that could contains some integer value.

When I select data from this field I should distinct if is an integer or text (Just to handle mysql operation like < or >) So I’ve tried :

$clause = "";
if(is_int($_GET['f']))
   $clause = " AND myValue < ".$_GET['f']."  ";
else
   $clause = " AND myValue = '".$_GET['f']."'  ";

$ds->query("SELECT * FROM myTable WHERE id = 1 ".$clause);

please note the quote in case it wasn’t an integer.

But this doesn’t work and it’s normal I think because the field has a type text.

Please have you any solution for this problem. Thanks in advance !

Answer 1

A text type column always treats its values as text (a string), so regardless of what value is stored, you need to enclose it in '. MySQL can compare a number as a string.

Also, is_int is not suitable for checking $_GET values, as they are considered strings. Use is_numeric instead.

But notice the comments to your question, a redesign is more suitable if you need to store integers and/or strings separately in your database.
