Select first row in each group using group by in sqlite
The following works for me with your sample table data:
SELECT MaxOfStatecountpercent, statepoolnumber, STATECODEFROM geoviewGROUP BY statepoolnumberHAVING MIN(ROWID)ORDER BY ROWIDThis assumes that, based on your desired input, you want the 'first' state of each statepoolnumber group to be the first record (rather than 'first' by alphabetical order).
