When passing a DATABASE.TABLE (string) to GetInsertSQL() in the $rs var, GetInsertSQL causes the following:
mysqli error: [1103: Incorrect table name 'DATABASE.TABLE'] in EXECUTE("SHOW COLUMNS FROM `DATABASE.TABLE`")
It appears GetInsertSQL is not passing the DATABASE.TABLE value and then wrapping each chunk, but rather wrapping backticks around the full string.
Bug appears in both v5.10 and v5.11.
Also driver is mysqli
