get-next-row

Arguments: &key db ignore

The db, which defaults to the value of *mysql* must be a mysql object such as returned by connect. This function returns a list of items in the next row. It returns nil if there are no rows left.

If ignore is specified true (it defaults to nil), then t is returned rather than a list of items if there is an unread row. If you have gotten all you wanted out of a query but haven't reached the end of the result set (i.e get-next-row hasn't returned nil yet) then you still must continue to call get-next-row until get-next-row returns nil (this keeps your client code in sync with the MySQL server). If you are just calling get-next-row until it returns nil then passing the argument :ignore t will tell get-next-row to not bother decoding the items in this row, which will save you some time and reduce consing.
