zq29 Posted March 20, 2006 Share Posted March 20, 2006 I have a field set as a varchar datatype, but on occasion I would need to treat it as if it were a float field in a php script, sometimes it may have a price in there that I wish to order from ascending to descending, and ofcourse, it doesn't work as expected when its a varchar field.I have tried something like this, with no luck, can this even be done?[!--sql--][div class=\'sqltop\']SQL[/div][div class=\'sqlmain\'][!--sql1--][span style=\'color:blue;font-weight:bold\']SELECT[/span] `price`[color=green]AS[/color] FLOAT() [color=green]FROM[/color] [color=orange]`table`[/color] [color=green]ORDER BY[/color] `price` [color=green]ASC[/color] [!--sql2--][/div][!--sql3--] Link to comment https://forums.phpfreaks.com/topic/5335-select-a-field-as-a-different-datatype/ Share on other sites More sharing options...
wickning1 Posted March 20, 2006 Share Posted March 20, 2006 [code]SELECT CAST(`price`AS DECIMAL) AS myprice FROM table ORDER BY myprice ASC[/code]This will NOT use any index you may have on `price`, so it will have to sort it every time you make the query. The best way to handle this is to change the column in mysql to a DECIMAL or FLOAT type.
