How Can I Verify the Final SQL Query Executed in a Parametrized Query with PDO in PHP?

Checking Final SQL Parametrized Query in PHP with PDO

When using PHP with PDO to access a MySQL database with parametrized queries, there may arise a need to verify the final SQL query that will be executed. However, it is important to note that:

Short Answer

As stated by Ben James, the full SQL query does not exist on the PHP side. This is because the query with tokens and the parameters are sent separately to the database. The full query is only generated on the database side.

Workaround

As a workaround, you can log all SQL queries to observe the actual queries being executed on the server. In MySQL, this can be achieved by modifying the my.cnf (or my.ini) file and adding the following line:

log=[REPLACE_BY_PATH]/[REPLACE_BY_FILE_NAME]

However, it is crucial to refrain from using this method in a production environment.
