There is no SQL language command to assign a name to a cursor. You can use the JDBC setCursorName method to assign a name to a ResultSet that allows positioned updates and deletes. You assign a name to a ResultSet with the setCursorName method of the Statement interface. You assign the name to a cursor before executing the Statement that will generate it.
Statement s3 = conn.createStatement(); // name the statement so we can reference the result set // it generates s3.setCursorName("UPDATABLESTATEMENT"); // we will be able to use the following statement later // to access the current row of the cursor // a result set needs to be obtained prior to using the // WHERE CURRENT syntax ResultSet rs = s3.executeQuery("select * from FlightBookings FOR UPDATE of number_seats"); PreparedStatement ps2 = conn.prepareStatement( "UPDATE FlightBookings SET number_seats = ? " + "WHERE CURRENT OF UPDATABLESTATEMENT");
Typically, you do not assign a name to the cursor, but let the system generate one for you automatically. You can determine the system-generated cursor name of a ResultSet generated by a SELECT statement using the ResultSet class's getCursorName method.
PreparedStatement ps2 = conn.prepareStatement( "UPDATE employee SET bonus = ? WHERE CURRENT OF "+ Updatable.getCursorName());
