The sql query generating for these look like
'SELECT db_functions_author.id, db_functions_author.name, db_functions_author.alias, db_functions_author.goes_by, db_functions_author.age, (db_functions_author.alias) :> UNSIGNED BIGINT AS cast_int FROM db_functions_author'
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' UNSIGNED BIGINT AS cast_int FROM db_functions_author'
