How to View SQL Queries Executed by Django?

Troubleshooting Django's SQL Queries

This question investigates methods for viewing the SQL queries executed by Django during query operations.

Solution:

According to the Django documentation FAQs, Django provides two options for inspecting SQL queries:

• django.db.connection.queries: This attribute contains a list of all SQL queries executed by Django. It can be accessed as follows:

<code class="python">from django.db import connection
print(connection.queries)</code>

• Queryset.query: Each queryset object has a query attribute that holds the query to be executed. Here's an example:

<code class="python">print(MyModel.objects.filter(name="my name").query)</code>

Note: The query output displayed by these methods is not valid SQL syntax. Django never interpolates query parameters but instead sends the query and parameters separately to the database adapter for execution, ensuring data integrity. Therefore, do not execute the query output directly in a database.

To reset the query list, for instance, to monitor the number of queries executed within a specific time frame, use reset_queries from django.db:

<code class="python">from django.db import reset_queries
from django.db import connection

reset_queries()
# Execute your query here
print(connection.queries)  # Returns an empty list</code>
