Yes, thank you. >>> Peter Horsbøll Møller <[EMAIL PROTECTED]> 01/15/04 10:01AM >>> I think you are looking for TOP10, TOP20 or TOP100 function. This feature is not supported directly in MapInfo, but you can get there if you do like this:
Start by doing your normal group query (note the special Order By section) Select Columns: Province, Type, Sub_Type, Count(*) "COUNT" >From Tables: National_Health_Facility_List_ Group By Columns: Province, Type, Sub_Type Order By Columns: COUNT Desc into Table Named: Count_Test Now we do a query were we only take the first 20 records from the previous result: Select Columns: * >From Tables: Count_Test Where: ROWID <= 20 Group By Columns: Order By Columns: COUNT Desc into Table Named: Count_Test_TOP20 But this is not the correct way, so you might see strange things...
