> On an existing table table, executing "ALTER TABLE ADD IF NOT EXISTS
> thisColAlreadyExists varchar, thisColDoesNotExist varchar", then
> nothing will be changed in the table because thisColAlreadyExists
> already exists.
> Omitting the already-existing column from the statement, all new columns
> do get created.
> The general expectation would be that when you use ADD IF NOT EXISTS, all
> non-existent columns will be added, and all existing columns in the
> statement will just be ignored. There is already an integration test
> (AlterTableIT#testAddVarCols) that actually demonstrates the current
> behavior, although this is probably not correct.
> As pointed out in the related mailing list thread [1], ALTER TABLE DROP COLUMN likely
suffers from the same issue.
