For maximum interoperability, the gateway client should assume only SQL-92-standard pattern matching (the percent (%) and underscore (_) wildcard characters).
The permission information about execute access to a specific stored procedure for the current user is not necessarily checked; therefore, access is not guaranteed. Note that only three-part naming is used. This means that only local stored procedures, not remote stored procedures (which require four-part naming), are returned when they are executed against SQL Server. If the server attribute ACCESSIBLE_SPROC is Y in the result set for sp_server_info, only stored procedures that can be executed by the current user are returned.
sp_stored_procedures is equivalent to SQLProcedures in ODBC. The results returned are ordered by PROCEDURE_QUALIFIER, PROCEDURE_OWNER, and PROCEDURE_NAME.
