Getting resultset from insert statement

Question

i have the below code, where I'm inserting records to a table. When I try to get resultset, it returns null. How to get the latest added row into a resultset?

String sql1 = "INSERT INTO [xxxx].[dbo].[xxxxxx](WORKFLOW_SEQ_NBR," +
                      " WORKFLOW_LOG_TYPE_CODE, WORKFLOW_STATUS_CODE, DISP_CODE, DISP_USER, DISP_COMMENT, DISP_TITLE, DISP_TS)" +
                      "VALUES(?,?,?,?,?,?,?,?)";
        PreparedStatement pst = connect.prepareStatement(sql1);
        pst.setString(1, ...);
        pst.setString(2, ...);
        ...
        ...
        ...
        pst.executeUpdate();

        ResultSet rstest = pst.executeQuery();
//          ResultSet rstest = pst.getResultSet();

EDIT: Resolved

added following method to go to the last added row

st.execute("Select * from [xxxx].[dbo].[xxxxxxxxx]");
        ResultSet rstest = st.getResultSet();
        rstest.afterLast();
        GETLASTINSERTED:
        while(rstest.previous()){
            System.out.println(rstest.getObject(1));
            break GETLASTINSERTED;//to read only the last row
        }

When using a SQL statement such as INSERT, UPDATE or DELETE with a PreparedStatement, you must use executeUpdate, which will return the number of affeted rows. In this case there is simply no ResultSet produced by the sql operation and thus calling executeQuery will throw a SQLException.

If you actually need a ResultSet you must make another statement with a SELECT SQL operation.

See the javadoc for PreparedStatement#executeQuery and PreparedStatement#executeUpdate
