Evgeny Stanilovsky commented on IGNITE-15926:
---------------------------------------------

I suppose it resolved erroneously, correct exception not thrown. Plz reopen it?
I can call more that once tableManager.dropTable("TBL_NAME") and no exception thrown, also a can call it with not existing table, and no exception will be raised.

> ANSI standard requires two methods for dropping table for the two DDL:
> _DROP TABLE [ IF EXISTS ] syntax_
> for the purpose, Table manager should provide two methods with similar semantic.
> {code}
> TableManager#dropTable(String) throws TableNotExists
> TableManager#dropTableIfExists(String)
> {code}
> Also we need to support [1] ALTER TABLE [ IF EXISTS ] [ADD|DROP|ALTER] COLUMN
