**SOLVED** GROUP BY in the order they are defined in WHERE?

[zq29]

Say I have the following query:
[!--sql--][div class=\'sqltop\']SQL[/div][div class=\'sqlmain\'][!--sql1--][span style=\'color:blue;font-weight:bold\']SELECT[/span] * [color=green]FROM[/color] [color=orange]`table`[/color] [color=green]WHERE[/color] `field`[color=orange]=[/color][color=red]"c"[/color] [color=blue]OR[/color] `field`[color=orange]=[/color][color=red]"d"[/color] [color=blue]OR[/color] `field`[color=orange]=[/color][color=red]"a"[/color] GROUP BY `field` [!--sql2--][/div][!--sql3--]
This returns a result set ordered a, c, d. Is is possible to have the result set ordered by how they were defined in the WHERE part: c, d, a? I tried searching the MySQL manual, but as always, I just can't find what I'm looking for in that excuse for a manual...

Any help is greatly appreciated.

It's not exactly a "documented" use of the FIELD() function, but it should work (UNTESTED):

[code]SELECT * FROM `table` WHERE `field`="c" OR `field`="d" OR `field`="a" GROUP BY `field` ORDER BY FIELD(`field`,'c','d','a')[/code]

Hope that helps.
