Richfaces Datatable - Sort specific column on load

Is it possible to sort a datatable by a specific column when it first loads? Or does it need to be done using the DAO? When I put on ORDER 开发者_开发问答BY in my SQL in my DAO, no data at all is returned in the datatable

Solved it used sortOrder="DESCENDING" or sortOrder="ASCENDING" on the column you wish to have sorted when datatable first loads

Just need to add this to options:

"aaSorting": [[ 5, "desc" ]]
