I am working on a React web app that will enable the user to store new data rows and edit/udpate old data rows. The reference data, for the React form, is stored in ADLS Gen1 parquet format and the app will write data to a different ADLS location in parquet format.
The question is: How can I setup the Django backend with these two different data source? I want to read some reference data from ADLS Gen1 and write and edit into another ADLS in parquet format.
You can use different databases in django settings like this below :
DATABASES = {
'DB1': {
'ENGINE': 'mssql',
'NAME': 'DB_NAME',
'USER': 'sa',
'PASSWORD': 'PASSWORD',
'HOST': 'HOST',
'PORT': '',
'OPTIONS': {
'driver': 'ODBC Driver 11 for SQL Server',
},
},
'DB2': {
'ENGINE': 'mssql',
'NAME': 'DB_NAME',
'USER': 'sa',
'PASSWORD': 'PASSWORD',
'HOST': 'HOST',
'PORT': '',
'OPTIONS': {
'driver': 'ODBC Driver 11 for SQL Server',
},
},
}
Then on your ORM you can use tbl.objects.using('DB1').all()

After reading the documentation, I've encountered a problem, I'm getting the error unable to connect to the database. I'm trying to connect to a local SQL Server database, using NestJS. I enabled a user sa and set its password. I also enabled TCP/IP connection and confirmed the port from SQL Server. I'm wondering what am I missing or doing wrong?
#Module({
imports: [
ConfigModule.forRoot({
envFilePath:'.env',
isGlobal: true
}),
TypeOrmModule.forRoot({
type: 'mssql',
host: 'localhost',
port: 1433,
username: 'root',
password: 'root',
database: 'test',
autoLoadEntities: true,
synchronize: true,
}),
],
controllers: [AppController, EstadoProyController],
providers: [AppService],
})
export class AppModule {}

1- sql server running
2- check your port or host
OK, I'm slowly going crazy. I want to connect Django 3 to MSSQLv15 Server. Connection works if I use Trustedconnection=yes (using win credentials), it also works on Ubuntu if I'm using FreeTDS v7.4 but it won't work in Windows if I manually insert service account or personal credentials and use sql login. Is it some kind of dependency issue? I have tried various library version combos, but to no avail.
Error message is:
conn = Database.connect(connstr,
django.db.utils.InterfaceError: ('28000', "[28000] [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Login failed for user 'DOMAIN\\user'. (18456) (SQLDriverConnect); [28000] [Microsoft][ODBC Driver 17 for SQL Server]Invalid connection string attribute (0)")

ODBC Driver 17 for SQL Server doesn't seem to support authenticating domain users via username and password, where FreeTDS does (see https://stackoverflow.com/a/37702329/9461432). On a non-Windows machine, Microsoft directs you to use Kerberos.
Authenticating via username & password works fine if you're connecting to a user that uses SQL Server authentication (ie. non-domain).
I'm trying to connect to SQL Server studio v17.2
This is the code that works fine in my local computer
DATABASES = {
'default': {
# 'ENGINE': 'django.db.backends.sqlite3',
# 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
'ENGINE': 'sql_server.pyodbc',
'NAME': 'database',
'HOST': '10...',
'USER': 'user',
'PASSWORD': 'password',
#'DRIVER':'ODBC Driver 17 for SQL Server'
'OPTIONS': {
'driver': 'ODBC Driver 17 for SQL Server',}
}
}
This is the error I am getting:
windows django data source name not found and no default driver specified
As the title says. Im getting this error
django.db.utils.InterfaceError: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')
Heres my code
DATABASES = {
'default': {
'ENGINE': 'sql_server.pyodbc',
'NAME': 'dbname',
'USER': 'user',
'PASSWORD': 'password',
'HOST': 'HOST',
'PORT': '',
'OPTIONS': {
'driver': 'ODBC Driver 13 for SQL Server',
},
}
}
DATABASE_CONNECTION_POOLING = False
Check first if you have that driver installed:
import pyodbc
print(pyodbc.drivers())

I need help with setting up my project. I used django-pyodbc-azure and I have this in my settings.DATABASES:
DATABASES = {
'default': { 'ENGINE': 'sql_server.pyodbc','NAME': 'DBNAME','USER': 'USER',
'PASSWORD': 'PASSWORD',
'HOST': '10.xx.xx.xx,1433',
'OPTIONS': {
'driver': 'SQL Server Native Client 10.0',
},
},
}
Sorry I don't know how to format the code above.
I don' know the problem is, but it returns an error:
ProgrammingError: ('42S02', "[42S02] [Microsoft][SQL Server Native Client 10.0][
SQL Server]Invalid object name 'django_session'. (208) (SQLExecDirectW); [42000]
[Microsoft][SQL Server Native Client 10.0][SQL Server]Statement(s) could not be
prepared. (8180)")
How do I fix this?
Try this:
DATABASES = {
'default': {
'ENGINE': 'sql_server.pyodbc',
'NAME': 'mydb',
'USER': 'user#myserver',
'PASSWORD': 'password',
'HOST': 'myserver.database.windows.net',
'PORT': '',
'OPTIONS': {
'driver': 'ODBC Driver 13 for SQL Server',
},
},
}
