Inspectdb errors and support schemas for MSSQL

[Amanjeev Sethi]

Please correct me if I missed this in the wrapper or the original library. I understand that this is a wrapper to django-mssql but I was wondering if this is a better starting place to ask this. We have a rather large database with at least three different schemas. It seems to me that while running inspectdb, schemas are not supported. I think it will be helpful to use Schemas as they are an integral part of the MSSQL databases.

Moreover, running inspectdb on my database returns errors for the first table itself even if the table is given all permissions for anyone. I tried running myschem.PROD_DONE as well but that also gave the same error.

Edit: More information -

Running SELECT * FROM myschem.PROD_DONE where 1=0 directly in the SQL serer studio does not give any error but while inspectdb runs, this line https://bitbucket.org/Manfre/django-mssql/src/8ac825580d01c653256d21931e87caf3aa3513fb/sqlserver_ado/introspection.py?at=stable/1.6#cl-109 fails.

I've opened a ticket https://bitbucket.org/Manfre/django-mssql/issue/67/schema-support-for-inspectdb-and-other.

Can you provide full command with parameters? e.g. python manage.py inspectdb

[Amanjeev Sethi]

Mostly this -

python manage.py inspectdb --database=mydbname

[Suman Nepal]

Did they provide any fix for this issue? I am having the same problem
