Question

I have to perform a SELECT operation in the DB. Since I want to narrow down the search results, I was wondering if I should use nested SELECTs or use a JOIN operation?

I want to perform a dual search on the table. I unsuccessfully tried this:

$receive_listings = mysql_query('SELECT * 
                                   from show_detail 
                                  WHERE ch_id="0140.zee.in" IN ('SELECT * 
                                                                   FROM show_detail 
                                                                  WHERE `date_column` BETWEEN `2010-08-17` AND `2010-08-18`')'
                                ) or die("ERROR: $receive_by_show_id.".mysql_error());

throws an error:

Parse error: syntax error, unexpected T_VARIABLE in /Applications/XAMPP/xamppfiles/htdocs/play/browse-channels-shows.php on line 17

I was wondering if a JOIN operation would do the trick more efficiently?

Answer 1

Since others have already solved your parse error, you’re going to end up with a second error because your query isn’t correct.

I’m assuming you’re trying to get items between your two dates and match your ch_id:

SELECT * from show_detail WHERE ch_id="0140.zee.in" AND (`date_column` BETWEEN `2010-08-17` AND `2010-08-18`')
