The catalog stored procedures sp_columns, sp_datatype_info, sp_special_columns, and sp_sproc_columns use the catalog stored procedure tables spt_datatype_info, spt_datatype_info_ext, and spt_server_info in the sybsystemprocs database to convert internal system values such as status bits into human-readable format.
The catalog stored procedures sp_column_privileges and sp_table_privileges create and then drop temporary tables.
