Re: Help - select syntax if else
You don't even need the check field you can just directly check the contents of the image field. Although I'm not sure if you are trying to set a filter or display something different. If you want to display a conditional on a field then you need to specify that field directly. select *,if(image,1,0) as ImagePresent from foo1 where ... If you don't want to spell out all of the fields, that's the easiest syntax. You'll can all your fields plus an extra column named ImagePresent that will be the same as your check column. You could just as easily have it show the image number instead of a 1 or 0. select *,if(image,image,no image) as ImageNumber from foo1 where ...

Re: Help - select syntax if else
* Svens Klave Can anybody help me with select query I can try. how to do this: I have table foo1 with two fields image check | image | check | | 6782 | 0 | | 2732 | 1 | | 6734 | 1 | so I want to make query select * from foo1 where [so is it possible to make some if check=1 then image is image but if check=0 then into image goes other content for example noimage] I mean I need to check if there is 0 or 1 and so if check is 1 then show original number from image field but if there is 0 then it SELECT check,IF(check,image,'noimage') AS image FROM foo1; changes original content to noimage eh... a select statement can not change the database. The above SELECT will change the output of the image column according to your specification, but it will not change the database. You would need to use UPDATE for that: UPDATE foo1 SET image = 'noimage' WHERE check = 0; -- Roger - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?
