如何获得将在DB2中执行PreparedStatement的完整查询？

Question

I'm working on a dynamic web project and using the PreparedStatement to execute the SQL queries against the DB2 database.

String myQuery = "select id from user where name = ?";
PreparedStatement stmt  = connection.prepareStatement(myQuery);
stmt.setString(1, test);
ResultSet resultSet  = statement.executeQuery();

How can I receive the full SQL query that is about to be executed on the DB2 server in the console?

If you are familiar with Debugging options in Eclipse. You may try the following:

1. Set a Breakpoint at ResultSet resultSet = statement.executeQuery();

2. Right click your application, say Debug As select Java Application (or Whatever applicable in your case ie may be SpringBoot App etc.

3. Perform step that gets you to code mentioned in the Question.

4. If you check Variables tab in Debug Perspective of Eclipse, you will find variables like myQuery , stmt (according to your code)

5. Whatever you see as value of stmt would be the full SQL query you need.

Also, if you don't want to keep looking at this variable always you may try Java Logging and Print your Full SQL query in Logs.
