Can we execution sql script through java ?

Question

Hi All,
Can we execute sql script ("name.sql") through java programe.
I am not talking about reading sql script one by one and excute.
I just want to send this sql script to oracle console.
Or any body can give other alternative I have to lot of db operation in less time.

Kumar,
not sure whether this is any help, but you can try and use the code below.
I've knocked it together in about an hour so it's far from production ready (particularly, assumes one-line comments starting with '#' and nothing else - queries are assumed multi-line, but terminated by ';' the following would cause trouble:
SELECT * FROM table; SELECT *
FROM another_table;
and, of course, you can't get to the ResultSet.
But, hey, it's a start!
Best,
Marco.
