Some of multiple statements in a DDL file/string are ignored

[devxor]

Describe the bug
Having DDL in a file with multiple statements like in the example below will ignore the COMMENT line, so in the parsed result there will be no information about comment.

To Reproduce

CREATE OR REPLACE TABLE mytable (
    field_1 NUMBER(38, 0) NOT NULL,
    field_2 VARCHAR(250)
);

COMMENT ON COLUMN field_1 IS 'some comment';

Expected behavior
All the statements from DDL file/string parsed correctly and included in the result.
