Обсуждение: Display SQL from Java Prepared Statement

Is there a way I can have the JDBC driver dump out to a log file all of the SQL statements executed?  I am using prepared statements.

Note:  I think the development team is doing a great job.

Thanks,

Just call the toString() method of the prepared statement object. That will print the prepared statements SQL. It
includesnot just the SQL command but also some additional text before the SQL command. 
I'm using it also to write statements to the log.

Kind regards,

J,
I thought I had tried that before.  Good grief that was way to obvious.

I cannot even begin to thank you enough.  Thanks for the response.

But its not working for me ..

I have written like this :

/
 PreparedStatement pStatement = null;
 ....

 pStatement = connection.prepareStatement(" update tblMember set address =
?");
 pStatement.setObject(i++, "Jl. Setya Budi");
 System.out.println("query : " + pStatement.toString());

/

And the result :

/query : org.apache.tomcat.dbcp.dbcp.DelegatingPreparedStatement@1c1de1c/

I need log query from pStatement, Does anyone can help me ?

regard,

mimi

You are using a connection pool that wraps the statement object.
You'll need to unwrap it, or modify the connection pool's
implementation so that toString() delegates to the underlying
statement.
