 Description   

When running in sql_mode=ORACLE, MariaDB should understand predefined exception names.

BEGIN
 
  ...
 
EXCEPTION
 
  WHEN TOO_MANY_ROWS THEN ...
 
  WHEN NO_DATA_FOUND THEN ...
 
  WHEN OTHERS THEN NULL;
 
END;

Under terms of this task we'll implement the most important predefined exceptions:

  • TOO_MANY_ROWS
  • NO_DATA_FOUND
  • DUP_VAL_ON_INDEX

Other predefined exception names will be implemented by MDEV-10586.
