How Can I Debug and View Django's SQL Queries?

Troubleshooting Django SQL query issues

Debugging database interactions in Django can be challenging. Fortunately, there are ways to see the raw SQL queries that Django is executing.

Access SQL query

To access the executing SQL query, you can leverage Django’s connection object:

<code>from django.db import connection
print(connection.queries)</code>

This will display a list of executed queries. Note that due to Django's parameterization, these queries may not be valid SQL.

Another way is to access the query attribute of the queryset:

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

Reset query

If you need to reset the query list, for example to track the number of queries executed during a specific time period, you can use the reset_queries helper function:

<code>from django.db import reset_queries
from django.db import connection

reset_queries()
# 在此处运行您的查询
print(connection.queries)
# 将返回一个空列表</code>

By leveraging these techniques, you can understand the SQL queries executed by Django and troubleshoot issues that may arise in database interactions.
