Research direction

Reproduce select * from /*!i*/nformation_schema.tables; in the SQL lexer/parser and inspect how inline comments are handled. Compare the result with MySQL and MariaDB behavior; done means the malformed query is rejected, ideally with a regression test for this input.

Description

bug
Describe the bug

The query:
select * from /*!i*/nformation_schema.tables;

Executes as if it were:
select * from information_schema.tables;

This is improper.

Expected behavior

MySQL and MariaDB return an error message, this is probably the most expected result. Perhaps a syntax error should be generated from the parser.
