karldesign Posted July 5, 2007 Share Posted July 5, 2007 Just a quick (and probably obvious) question... In the past, I have used a standard query to first compare a userId from a login session with the userId of a database sample. From this, I could redirect if it isn't the user or keep the user on the page if it is them. Having thought about it, there must be a quicker and more efficient way of doing this and wandered if there was an 'IF' statement that would do the same. (ie: UPDATE table WHERE row = get AND (IF row = session)). Quote Link to comment Share on other sites More sharing options...
Wildbug Posted July 5, 2007 Share Posted July 5, 2007 Could you clarify a bit more? Quote Link to comment Share on other sites More sharing options...
akitchin Posted July 5, 2007 Share Posted July 5, 2007 the MySQL manual: http://dev.mysql.com/doc/refman/4.1/en/control-flow-functions.html#function_if as wildbug says, it's not totally clear what you want to do. MySQL can't take care of header redirection for you. Quote Link to comment Share on other sites More sharing options...
Illusion Posted July 5, 2007 Share Posted July 5, 2007 UPDATE table set id=id+1 WHERE row = get AND IF(row = session,TRUE,FALSE); I don't know it works or not as per my knowledge it does not make any difference in performence prospective, it is always better if u use UPDATE table set id=id+1 WHERE row IN ('get','session').
