Description

The parser currently shows warnings for CHECK constraints, which are supported in MariaDB 10.2.1+

ALTER TABLE t_a ADD CONSTRAINT CHECK(col = 42);

CREATE TABLE t_b (
    col INT CHECK(col = 37)
);

CREATE TABLE t_c (
    col INT,
    CHECK(col != 0xDEAD)
)

Research direction

Use the three SQL examples in the issue as reproduction cases and trace where CHECK constraints are parsed or reported as warnings. The work is done when ALTER TABLE and both CREATE TABLE forms are accepted without warnings for the supported MariaDB syntax.
