<!-- Answer --> Superset sends your SQL statements to StarRocks as-is and relies on the StarRocks SQLAlchemy driver and the database itself to support statements like `SHOW TABLES`, `SHOW DATABASES`, `SHOW CREATE TABLE`, `REFRESH EXTERNAL TABLE`, and `DROP TABLE ... FORCE`—there’s no extra filtering or blocking in Superset’s code for these statements[^1][^2][^3]. If these statements fail in SQL Lab but SELECT works, it’s likely due to either the StarRocks driver not supporting them via SQLAlchemy, or the Superset SQL parser (sqlglot) not recognizing the syntax and rejecting the query before execution[^4][^5]. To narrow it down, try running the same statements directly using a SQLAlchemy session or the StarRocks client. If they work there but not in Superset, check for any error messages in Superset’s logs when you run these statements—those details will help pinpoint if the issue is with SQL parsing or the driver. If you see a parsing error, it’s likely sqlglot not handling the statement; if you see a driver/database error, it’s likely a limitation of the StarRocks SQLAlchemy dialect.
