How can you log the actual SQL statement executed by a PreparedStatement?

Logging the Actual SQL Statement Executed by a PreparedStatement

Many Java developers encounter a challenge when using PreparedStatements: logging the actual SQL statement that is executed, instead of the template with placeholders. This problem arises because PreparedStatements separate the SQL statement from the actual values.

While it is important to log the SQL statement for debugging purposes, simply logging the template with placeholders does not provide sufficient information. To address this issue, we may consider the following alternative solutions:

Alternative Solutions:

• Output Statement with Placeholders and Data: Log the SQL code along with the list of data that was used to fill in the placeholders. This provides a clear understanding of the actual statement executed.
• Manual SQL Query Construction: Build the SQL query manually by concatenating the template with the actual values. While this method requires additional effort, it ensures that the logged SQL statement accurately reflects the executed query.

Conclusion:

Unfortunately, there is no direct way to obtain the actual SQL statement from a PreparedStatement. By employing one of the suggested alternative solutions, developers can provide valuable debugging information by logging the actual SQL query that was executed.
