How to view corresponding SQL query of the Django ORM’s queryset?

Is there a way I can print the query the Django ORM is generating?
Say I execute the following statement: Model.objects.filter(name='test')
How do I get to see the generated SQL query?


Answer 1:

Each QuerySet object has a query attribute that you can log or print to stdout for debugging purposes.

qs = Model.objects.filter(name='test')
print qs.query


I’ve also used custom template tags (as outlined in this snippet) to inject the queries in the scope of a single request as HTML comments.

Answer 2:

You also can use python logging to log all queries generated by Django. Just add this to your settings file.

    'disable_existing_loggers': False,
    'version': 1,
    'handlers': {
        'console': {
            # logging handler that outputs log messages to terminal
            'class': 'logging.StreamHandler',
            'level': 'DEBUG', # message level to be written to console
    'loggers': {
        '': {
            # this sets root level logger to log debug and higher level
            # logs to console. All other loggers inherit settings from
            # root level logger.
            'handlers': ['console'],
            'level': 'DEBUG',
            'propagate': False, # this tells logger to send logging message
                                # to its parent (will send if set to True)
        'django.db': {
            # django also has database level logging

Another method in case application is generating html output – django debug toolbar can be used.

Answer 3:

You can paste this code on your interpreter which will display all the SQL queries:

# To get all sql queries sent by Django from py shell
import logging
l = logging.getLogger('django.db.backends')

Answer 4:

As long as DEBUG is on:

from django.db import connection

For an individual query, you can do:


Answer 5:

Maybe you should take a look at django-debug-toolbar application, it will log all queries for you, display profiling information for them and much more.

Answer 6:

A robust solution would be to have your database server log to a file and then

tail -f /path/to/the/log/file.log

Answer 7:

You can use a Django debug_toolbar to view the SQL query.
Step by step guide for debug_toolbar usage :

Install the Debug_toolbar

pip install django-debug-toolbar

Edit file & add debug_toolbar to Installed apps, this should be added below to ‘django.contrib.staticfiles’. Also add debug_toolbar to Middleware.>

INSTALLED_APPS= [ 'debug_toolbar'] 

MIDDLEWARE = ['debug_toolbar.middleware.DebugToolbarMiddleware']

create a new list named INTERNAL_IPS in file> create new list at the end of file & add below list:


This will allow the debug to run only on internal developement server

Edit file of #Project & add below code:

if settings.DEBUG:
    import debug_toolbar
    urlpatterns = [
    url(r'^__debug__/', include(debug_toolbar.urls))       
    ] + urlpatterns

apply migrate & run server again

You will see an add-on on your web page at & if you click on SQL Query check box, you can actually see the run time of query as well.

Answer 8:

If you are using database routing, you probably have more than one database connection.
Code like this lets you see connections in a session.
You can reset the stats the same way as with a single connection: reset_queries()

from django.db import connections,connection,reset_queries
reset_queries()  # resets data collection, call whenever it makes sense

def query_all():
    for c in connections.all():
        print(f"Queries per connection: Database: {c.settings_dict['NAME']} {c.queries}")

# and if you just want to count the number of queries
def query_count_all()->int:
    return sum(len(c.queries) for c in connections.all() )
