How to Monitor Precise MySQLdb Queries During Execution

Debugging database queries can be crucial for optimizing performance and troubleshooting issues. To aid in this process, understanding the exact query executed by MySQLdb after parameter insertion is essential.

Does MySQLdb Offer a Query Printing Mechanism?

The documentation suggests a Cursor.info() method to retrieve information about the executed query. However, user reports indicate its absence in version 1.2.2.

Introducing the Cursor._last_executed Attribute

As an alternative to the unavailable Cursor.info(), an attribute named cursor._last_executed on the cursor object provides a solution. This attribute stores the most recently executed query string, even in cases where an exception occurs.

Benefits of Using Cursor._last_executed

Compared to other methods like profiling or MySQL query logging, this attribute offers several advantages:

• Ease of use: Easily accessible through the cursor object, reducing the need for additional code or log file correlation.
• No performance impact: Unlike profiling or query logging, this attribute does not introduce any performance overhead, making it suitable for production environments.
