hi guys

i'm trying to implement MDEV-4579, could anyone help me with parser + warning generation?

MDEV-4579 title: SQL PARSER - Add Ignore to SET SQL command

example:

SET @@some_global_variable_that_dont_exists=1

this cause an error

SET @@some_global_variable_that_dont_exists=1,@@some_variable_that_exists_and_should_be_changed=3

this cause an error and don't change the second variable

could we implement:

SET IGNORE @@some_global_variable_that_dont_exists=1,@@some_variable_that_exists_and_should_be_changed=3

this cause an warning (first variable don't exists) and change the second variable

thanks
