Constructor Detail

LoggingWrapper

public LoggingWrapper(ConnectionProvider conprovider)

This constructor is for your convenience. All SQL-Statements are logged to System.out. What this constructor does inside is the following:

 this(conprovider,
      new LogListener() {
          public void log(String sqlstmt) {
              System.out.println(sqlstmt);
          }
      });
 

---

LoggingWrapper

public LoggingWrapper(ConnectionProvider conprovider,
                      LogListener loglistener)

Every SQL-Statement will be handed over to the LogListener. Assuming you want to integrate your own Logging-Service you could do the following:

 LogListener loglistener = new LogListener() {
     public void log(String sqlstmt) {
         MyLogger.log(sqlstmt);
     }
 };
 ConnectionProvider conprovider = new DataSourceAdapter(myDataSource);
 ConnectionProvider loggingconprovider = new LoggingWrapper(conprovider, loglistener);
 SQL sql = new SQLExecuter(loggingconprovider);
 // ...
