我已经做了一个你可以使用的小片段:

from django.conf import settings
from django.db import connection


def sql_echo(method, *args, **kwargs):
    settings.DEBUG = True
    result = method(*args, **kwargs)
    for query in connection.queries:
        print(query)
    return result


# HOW TO USE EXAMPLE:
# 
# result = sql_echo(my_method, 'whatever', show=True)

它以参数函数(包含sql查询)来检查和args, kwargs需要调用该函数。结果它返回函数返回的内容，并在控制台中打印SQL查询。

在django中，如果你有这样的查询:

MyModel.objects.all()

do:

MyModel.objects.all().query.sql_with_params()

or:

str(MyModel.objects.all().query)

来获取SQL字符串

from django.db import reset_queries, connection
class ShowSQL(object):
    def __enter__(self):
        reset_queries()
        return self

    def __exit__(self, *args):
        for sql in connection.queries:
            print('Time: %s\nSQL: %s' % (sql['time'], sql['sql']))

然后你可以使用:

with ShowSQL() as t:
    some queries <select>|<annotate>|<update> or other 

它打印

时间:% s SQL: % s

对于Django 2.2:

当我使用。/manage.py shell时，大多数答案对我没有多大帮助。最后我找到了答案。希望这能对别人有所帮助。

查询所有查询信息。

from django.db import connection
connection.queries

查看单个查询的查询:

q=Query.objects.all()
q.query.__str__()

q。query只是为我显示对象。 使用__str__()(字符串表示)显示完整的查询。

你可以使用连接。在Django中运行原始SQL查询，如下所示:

# "store/views.py"

from django.db import transaction
from .models import Person
from django.db import connection
from django.http import HttpResponse

@transaction.atomic
def test(request):
    Person.objects.create(name="John") # INSERT
    
    qs = Person.objects.select_for_update().get(name="John") # SELECT FOR UPDATE
    qs.name = "Tom"
    qs.save() # UPDATE
    qs.delete() # DELETE
                 
    for query in connection.queries: # Here
        print(query)

    return HttpResponse("Test")

然后，原始查询打印在控制台，如下所示:

{'sql': 'INSERT INTO "store_person" ("name") VALUES (\'John\') RETURNING "store_person"."id"', 'time': '0.000'}
{'sql': 'SELECT "store_person"."id", "store_person"."name" FROM "store_person" WHERE "store_person"."name" = \'John\' LIMIT 21 FOR UPDATE', 'time': '0.000'}      
{'sql': 'UPDATE "store_person" SET "name" = \'Tom\' WHERE "store_person"."id" = 179', 'time': '0.000'}
{'sql': 'DELETE FROM "store_person" WHERE "store_person"."id" IN (179)', 'time': '0.000'}
[24/Dec/2022 06:29:32] "GET /store/test/ HTTP/1.1" 200 9

然后，把reset_queries()放在Person.objects.select_for_update()之后，如果你想只得到UPDATE和DELETE查询，而没有INSERT和SELECT FOR UPDATE查询，如下所示:

# "store/views.py"

from django.db import transaction
from .models import Person
from django.db import reset_queries
from django.db import connection
from django.http import HttpResponse

@transaction.atomic
def test(request):
    Person.objects.create(name="John") # INSERT
    
    qs = Person.objects.select_for_update().get(name="John") # SELECT FOR UPDATE
    reset_queries() # Here
    qs.name = "Tom"
    qs.save() # UPDATE
    qs.delete() # DELETE
                 
    for query in connection.queries: # Here
        print(query)

    return HttpResponse("Test")

然后，只打印UPDATE和DELETE查询，不打印INSERT和SELECT FOR UPDATE查询，如下所示:

{'sql': 'UPDATE "store_person" SET "name" = \'Tom\' WHERE "store_person"."id" = 190', 'time': '0.000'}
{'sql': 'DELETE FROM "store_person" WHERE "store_person"."id" IN (190)', 'time': '0.000'}
[24/Dec/2022 07:00:01] "GET /store/test/ HTTP/1.1" 200 9

我已经做了一个你可以使用的小片段:

from django.conf import settings
from django.db import connection


def sql_echo(method, *args, **kwargs):
    settings.DEBUG = True
    result = method(*args, **kwargs)
    for query in connection.queries:
        print(query)
    return result


# HOW TO USE EXAMPLE:
# 
# result = sql_echo(my_method, 'whatever', show=True)
