Possible to get Max value by index column ?

Hi,

Any ways I can get the max value through index column,
like SQL: Select Max(column1) from tableName where indexColumn ='value1'
Thanks

You could fetch all the rows that match the indexColumn='value1' then sort
them on the client side.  However, that's probably not what you want...
