How Can I See the SQL Queries Generated by Django's QuerySet?

Delving into SQL Queries with Django QuerySet

Getting a glimpse into the SQL queries generated by Django can be invaluable for troubleshooting and optimizing your database interactions. The QuerySet object, a crucial component of Django's ORM, provides a way to access the underlying SQL statement.

Revealing the SQL Behind the QuerySet

To retrieve the SQL that Django will execute on the database, simply invoke the query attribute:

queryset = MyModel.objects.all()
print(queryset.query)

This will print a string representation of the SQL query that Django has constructed. The output looks something like:

SELECT "myapp_mymodel"."id", ... FROM "myapp_mymodel"

Example:

Consider the following QuerySet:

queryset = MyModel.objects.filter(name="John").order_by("age")

Using the query attribute, you can reveal the corresponding SQL statement:

SELECT "myapp_mymodel"."id", ... FROM "myapp_mymodel"
WHERE "myapp_mymodel"."name" = 'John'
ORDER BY "myapp_mymodel"."age"

This can help you validate the query's logic, ensuring that it accurately captures your intended database operations.
