Help with Join Query
Hi gang. I have searched and searched and cannot figure out what/why this query is wrong.

Code:
$query = "(SELECT * FROM table1 WHERE keywords LIKE '%".$term."%') UNION ALL (SELECT * FROM table2 WHERE keywords LIKE '%".$term."%')";


Table 1 and Table 2 are not relational. They are essentially two data storage tables. I want to search both to see if either match the related keyword (term). But my query fails. If I run each query by itself, it works fine.

What do you mean 'fails'? Are you getting an error, or just unexpected result sets?

I keep getting my 'die' results.

I'm guessing you're not selecting the same number of columns from each of your selects. Use this to get MySQL's error message; it'll give you a more specific idea of the problem.

PHP Code:
 $result = mysql_query($query) or die("Could not execute Union search: " . mysql_error());

Great! You are correct. Ok I was doing a select *, so alternatively if I manually selected an equal number of columns, it should work.


Awesome, off to try it!
