coldfusion - SQL... Get Value from Field based on Max value of Another Field -


having complete sql mental lapse today , can't figure out. coldfusion , ms access

i'm looking query of query in coldfusion.

original query:

<cfquery name="myquery" datasource="xxx"> select name, id, tblloc.directions, tblloc.locationorder mytable  .....              order tblloc.locationorder </cfquery>

i want create query query retrieve directions locationorder max.

thus, if myquery returned:

name       id        directions      locationorder aa         10         aaaaaa            1 bb         11         bbbbbb            2  qoq return:  directions bbbbbb

but every iteration of seemingly simple sql i've tried fails. must half-asleep or something.

<cfquery name="latestdirections" dbtype="query"> select directions myquery locationorder=(select max(locationorder) myquery) </cfquery>  <cfquery name="latestdirections" dbtype="query"> select directions, max(locationorder) maxlocationorder get_sel_locations </cfquery>

nope... neither it.

...the second, "column get_sel_locations.directions invalid in select list clause because not contained in aggregate function , there no group clause"

the error pretty clear. missing group clause. when using aggregates max() have group results non-aggregated columns. in case: directions

select directions, max(locationorder) maxlocationorder get_sel_locations group directions

update if want maximum everything, yisroel's query want.

update mentioned in comments, qoq not database queries. support functions/syntax listed in documentation http://livedocs.adobe.com/coldfusion/8/using_recordsets_3.html
