Unlimented selection conditions

Recommended Posts

Okay, I\'m writing a script that I was to have an infinite amount of selection conditions.

 

Think something like

 


foreach($condition as $_){

$con .= "$_ AND";

}



// enter code to get rid of that last AND...



$result = mysql_query("select * from `table` where $con");

 

However, will something go wrong is there are too many conditions? I mean, I\'m not talking thousands, but like 50? 100?

 

I know there will be performance issues but that\'s not a big deal, so long as were just talking 5-10 seconds, maybe a tad more but definitely well under 30, which seems to be timeout level.

 

Anyone know a better alternative? I was thinking about doing a big loop of mysql_result checks but would that even be faster? (I know there are a ton of optimizations in mySQL). Plus the way I have now is soooo easy. I mean, I turned a collage level problem into a comp sci 1 extra credit problem with my idea, just kinda looking for a better implementation of basically the same idea. especially a way to break that one huge query into many smaller queries.

 

Thanks a bunch if you can help. I\'m not that good on mySQL yet when it comes to the higher level queries. (doc\'s seem way to reference like to really read through).
