How to merge two tables?

[wanda46]

I have two tables with exactly same structure (same fields: id, title, content). I want to merge/combine them. I used the following SQL:

CREATE TABLE total (id INT AUTO_INCREMENT PRIMARY KEY, title varchar (200) NULL,
content text NULL,
)

TYPE=MERGE UNION=(table1,table2) INSERT_METHOD=LAST;

But it did not work! Seems that it stucks at INSERT_METHOD=LAST

I am wondering since the two tables may have duplicate id, so it may not work. So what is the easiest way to merge two tables?

Thanks for your help!
