Commit 79993565 authored by unknown's avatar unknown

Fixed some basic error handling for SP functions in mysql_execute_command().


include/mysqld_error.h:
  Added error codes for SPs

  Changed return value of mysql_execute_command() from void to int; need to be able
  to detect if executions of substatements in SPs failed.

sql/sp_head.cc:
  Moved net.no_send_ok fiddling to sql_parse.cc.
  Check if mysql_execute_command() failed.
sql/sql_parse.cc:
  Changed return value of mysql_execute_command() from void to int; need to be able
  to detect if executions of substatements in SPs failed. Fixed all returns
  accordingly.
  Added error checks for SQLCOM_CREATE_PROCEDURE, CALL, ALTER_PROCEDURE, and
  DROP_PROCEDURE.
