format(query, sizeof(query), "SELECT * FROM `racerotation` WHERE race =  %s ", race);

Strings need apostrophes around the specifier like this '%s' but you must escape any input by the players. Use mysql_format and '%e' specifier.

In the callbacks you use cache functions, check if there are rows before using these functions. No data will result in error for invalid row indexes.
