Question

I normally do a join like this:

$query = "SELECT table1.ColA, table2.ColC ".
     "FROM table1, table2".
        "WHERE table1.uid = table2.uid";

But in this case the WHERE portion is already used to specify a record using a PHP variable. How do I JOIN table 2 in this case?

SELECT SQL_CALC_FOUND_ROWS ColA, ColB FROM Table1 WHERE value = $value

Answer 1

Please try this

$query = "SELECT table1.ColA, table2.ColC FROM table1, 
            table2 WHERE table1.uid = table2.uid and table1.value=$value";

OR

$query = "SELECT table1.ColA, table2.ColC FROM table1 INNER JOIN table2 
               ON (table1.uid = table2.uid) WHERE table1.value=$value";
