[SOLVED] Select question

[djtozz]

Hi,

 

First I would like to say that php is pretty new for me..

so please don't shoot me if this should be a stupid question!

 

But I'm a little surpized due to following..

 

I have a search script (very large mysql db) which is working pretty fast for searching!

I'm using following querry:

	$q="SELECT `url`,`caption`, `type`,`fsize`, MATCH (caption) AGAINST ('$kwd2') as score,`source`, `lastcheck`, `dateadded`, `desc`, `media`, `filename`, `sname`, `rating`, `stream`, `id`  FROM `v2links` WHERE  MATCH (caption) AGAINST ('$kwd2')$stype $fxtype $fxmedia $fsort LIMIT $start,$search_count";

sample: http://www.filemirrors.info

 

Now I would like to display the 30 latest records using following querry:

	$q="SELECT `url`,`caption`, `type`, `id`,`fsize`,`source`, `lastcheck`, `dateadded`, `desc`, `media`, `filename`, `sname`, `rating`, `stream`, `id`   FROM `v2links` Where  checked=1 $stype $fxtype $fxmedia $fsort LIMIT 30";

sample: http://www.filemirrors.info/latest.html

 

Now it seems to take much more time (3x) to display the last 30 records then when using the searchbox and enter a keyword...

 

I thought a simple select should be going faster then match against a keyword?

Is there an explenation for this or am I missing something?

 

Thanks,

INDEXES

 

Also what is contained in the following variables?

$stype $fxtype $fxmedia $fsort

Thanks for your feedback, I'm not sure what you mean with indexes..

 

Those variables have following value

 

$stype=" AND `fsize`<>''";

$fxmedia="AND media='avi'";

$fsort="ORDER by `lastcheck` ASC";

 

$fxtype is empty.

Add indexes to the following fields:

checked, fsize, media

 

Make sure you are using the most efficient data types for your fields.
