Maybe you don't quite understand what exactly has changed. The standard SQL syntax is as follows: ``` ALTER TABLE <table_name> ALTER COLUMN <col_name> <action> <action> ::= SET DATA TYPE <new_type> | SET NOT NULL | SET DEFAULT <default value>; ``` For example, it doesn't allow you to change the type and add NOT NULL constraint at the same time: `ALTER COLUMN SET DATA TYPE INT NOT NULL` - will not work. You have to drop NOT NULL contraint separately and that makes sense. Our previous syntax allows you to change the data type and add a NOT NULL constraint, but it does not allow you to change the type and remove NOT NULL, for example. -- This is an automated message from the Apache Git Service.
