Insert record and return the primary key

Question

Okay, I need to insert a record into a MSSQL database and return the primary key of that record. Im using the following code which is obviously wrong as I'm getting either 'NULL' or 'com.microsoft.jdbc.base.BaseResultSet@1d520c4' returned depending on the ways I've tried. The primary key is an int value called clientID which is incremented by one each time a new record is added.
// set the prepared statement
            String sql="INSERT INTO Client(username, country, clientIP, browser, os) VALUES(?,?,?,?,?)";
            PreparedStatement pstmt = conn.prepareStatement(sql);
            pstmt.setString(1, inUserName);
            pstmt.setString(2, inCountry);
            pstmt.setString(3, inClientIP);
            pstmt.setString(4, inBrowser);
            pstmt.setString(5, inOS);
            // Insert the row
            pstmt.executeUpdate();
            Statement stmt = conn.createStatement();
            ResultSet rs = stmt.executeQuery("SELECT SCOPE_IDENTITY()");
            System.out.println("Result "+rs);The primary key value is needed so that it can be used as a foregin key in another table. Am I going about this the correct way? Any help, pointers or code fixing would be appreciated.....

Answer 1

Yes. I tried this way but I only ever get the answer
of 0 when i print our the result! Not really sure
whats happening.That's because you don't print a ResultSet like that. In order to get the key out, you have to do this:
int key = 0;
while (rs.next())
    key = rs.getInt(1);What were you thinking with your code?
You might want to do this in a transaction. If the INSERT fails, you'll want to roll back.
The "select @@identity" is correct for M$ Access, SQL Server, and Sybase. I believe it's also correct for MySQL, but I'm not 100% certain of that.
