The Update Operation

Execute the update() method.

Using a while loop together with next(), move to the row that you want to update.

Assign updating value(s) to the fields of the table OTD

Update the row by calling updateRow().

package prjJDBC_JCDjcdALL;

public class jcdUpdate
{

    public com.stc.codegen.logger.Logger logger;

    public com.stc.codegen.alerter.Alerter alerter;

    public com.stc.codegen.util.CollaborationContext collabContext;

    public com.stc.codegen.util.TypeConverter typeConverter;

    public void receive( com.stc.connector.appconn.file.FileTextMessage input,

    {
        FileClient_1.setText( "Update the Rate and Last_update
 fields using Prepared Statement.. " );
        FileClient_1.write();
        otdJDBC_1.getUpdate_Ps().setEmp_no( typeConverter.stringToShort(
 input.getText(), "#", false, 0 ) );
        otdJDBC_1.getUpdate_Ps().executeUpdate();
        FileClient_1.setText( "Done Update." );
