I have a problem selecting guid data from a table using a simple resultset
Here is the code
java.sql.PreparedStatement ps = conn.prepareStatement("SELECT FORUM_ID, USER_ID FROM forum_users where id="
+ "?");
ps.setString(1, key);
rs = ps.executeQuery();
while (rs.next())
{
string forumId = rs.getString(1);
}
FORUM_ID - GUID
Can I select Guid on a simple resultset?
What java type corresponds to a GUID type?
Please a little help

Yes you can select a GUID on the sql side of things very easily. Your sql looks like it should be fine. As for the datatype of a GUID in java, I am not a java guy but I would bet it would take about 5 seconds on google to find it.

Hi. Thnx for your reply.
I've solved the problem replacing the uniqueidentifier with int and making the column "identity Column".
I've google-ed the problem, but it seams like java don't have a corresponding type of uniqueidentifier (Guid).
The only way to handle this problem is to use SQLServerResultSet or to use an alternative solution, like replacing uniqueidentifier with int 😉
