Oracle Database Discussions

I have installed the Express 10g version today and played around with it for a while.

If I go to the SQL commands GUI and enter one insert like this:

INSERT INTO pageit (PagID, PagParent, PagName, PagActive) VALUES (19, 17, 'Mango tree', 1)

then it works nicely:

But if I do this:

INSERT INTO pageit (PagID, PagParent, PagName, PagActive) VALUES (20, 17, 'Grape trees', 1);
INSERT INTO pageit (PagID, PagParent, PagName, PagActive) VALUES (21, 16, 'Animals', 1);

Then it says:

ORA-00911: invalid character

Looks like semicolon is not allowed,
but if I remove the semicolon then it says;
ORA-00905: missing keyword

Is there a way to use multiple insert statements in one go in this GUI at all?

If not, could someone please recommend how I do this.

I have exported thousands of insert lines from MySql and I would like to get them into my newly created Oracle table without having to type one line at the time in this gui.

Any suggestions?

Then if there is a nice WEB GUI like phpmyadmin for Oracle then I would like to know about that to? (Preferably free)
