Unique constraint not created in JPA

Question

I have created the following entity bean, and specified two columns as being unique. Now my problem is that the table is created without the unique constraint, and no errors

Answer 1

If you want the unique constraint, you should do it by sql:

ALTER TABLE cm_blockList ADD CONSTRAINT cm_blockList_unq UNIQUE (terminal);
