Compatibility warning: PEP-249 specifies that any modified parameters must be returned. This is currently impossible as they are only available by storing them in a server variable and then retrieved by a query. Since stored procedures return zero or more result sets, there is no reliable way to get at OUT or INOUT parameters via callproc. The server variables are named @_procname_n, where procname is the parameter above and n is the position of the parameter (from zero). Once all result sets generated by the procedure have been fetched, you can issue a SELECT @_procname_0, ... query using .execute() to get any OUT or INOUT values. Compatibility warning: The act of calling a stored procedure itself creates an empty result set. This appears after any result sets generated by the procedure. This is non-standard behavior with respect to the DB-API. Be sure to use nextset() to advance through all result sets; otherwise you may get disconnected. s SET @_%s_%d=%ss CALL %s(%s)t ,s @_%s_%d( R' t enumerateR< R@ RA RB RC RD RH R# R[ t ranget lent typeR R RN R+ ( R t procnameR9 R0 t indext argR` t i( ( s5 /usr/lib64/python2.7/site-packages/MySQLdb/cursors.pyt callproc s$ 3 c C s3 | j � } | | _ | j | � | j � | j S( N( R' t _last_executedRO R.
