cesar-loadsmart opened a new issue, #23251: URL: https://github.com/apache/superset/issues/23251
I've followed this [doc](https://superset.apache.org/docs/databases/sql-server/) to connect Superset with a Microsoft SQL Server Database, but using the recommended connection string `mssql+pymssql://<Username>:<Password>@<Host>:<Port-default:1433>/<Database Name>/?Encrypt=yes` did not work: <img width="846" alt="image" src="https://user-images.githubusercontent.com/89807801/222209478-0cd5302b-669c-45f3-9a33-602605a39de8.png";> Logs are also unclear: ``` SupersetErrorsException Traceback (most recent call last): File "/app/superset/databases/commands/test_connection.py", line 120, in run raise DBAPIError(None, None, None) sqlalchemy.exc.DBAPIError: (builtins.NoneType) None (Background on this error at: http://sqlalche.me/e/13/dbapi) The above exception was the direct cause of the following exception: Traceback (most recent call last): File "/usr/local/lib/python3.8/site-packages/flask/app.py", line 1499, in full_dispatch_request rv = self.dispatch_request() File "/usr/local/lib/python3.8/site-packages/flask/app.py", line 1485, in dispatch_request return self.ensure_sync(self.view_functions[rule.endpoint])(**req.view_args) File "/usr/local/lib/python3.8/site-packages/flask_appbuilder/security/decorators.py", line 89, in wraps return f(self, *args, **kwargs) File "/app/superset/views/base_api.py", line 113, in wraps raise ex File "/app/superset/views/base_api.py", line 110, in wraps duration, response = time_function(f, self, *args, **kwargs) File "/app/superset/utils/core.py", line 1507, in time_function response = func(*args, **kwargs) File "/app/superset/utils/log.py", line 245, in wrapper value = f(*args, **kwargs) File "/app/superset/views/base_api.py", line 83, in wraps return f(self, *args, **kwargs) File "/app/superset/databases/api.py", line 709, in test_connection TestConnectionDatabaseCommand(g.user, item).run() File "/app/superset/databases/commands/test_connection.py", line 145, in run raise DatabaseTestConnectionFailedError(errors) from ex superset.databases.commands.exceptions.DatabaseTestConnectionFailedError: [SupersetError(message='(builtins.NoneType) None\n(Background on this error at: http://sqlalche.me/e/13/dbapi)', error_type=<SupersetErrorType.GENERIC_DB_ENGINE_ERROR: 'GENERIC_DB_ENGINE_ERROR'>, level=<ErrorLevel.ERROR: 'error'>, extra={'engine_name': 'Azure Synapse', 'issue_codes': [{'code': 1002, 'message': 'Issue 1002 - The database returned an unexpected error.'}]})] 2023-03-01 13:09:04,232:WARNING:superset.views.base:SupersetErrorsException Traceback (most recent call last): File "/app/superset/databases/commands/test_connection.py", line 120, in run raise DBAPIError(None, None, None) sqlalchemy.exc.DBAPIError: (builtins.NoneType) None (Background on this error at: http://sqlalche.me/e/13/dbapi) The above exception was the direct cause of the following exception: Traceback (most recent call last): File "/usr/local/lib/python3.8/site-packages/flask/app.py", line 1499, in full_dispatch_request rv = self.dispatch_request() File "/usr/local/lib/python3.8/site-packages/flask/app.py", line 1485, in dispatch_request return self.ensure_sync(self.view_functions[rule.endpoint])(**req.view_args) File "/usr/local/lib/python3.8/site-packages/flask_appbuilder/security/decorators.py", line 89, in wraps return f(self, *args, **kwargs) File "/app/superset/views/base_api.py", line 113, in wraps raise ex File "/app/superset/views/base_api.py", line 110, in wraps duration, response = time_function(f, self, *args, **kwargs) File "/app/superset/utils/core.py", line 1507, in time_function response = func(*args, **kwargs) File "/app/superset/utils/log.py", line 245, in wrapper value = f(*args, **kwargs) File "/app/superset/views/base_api.py", line 83, in wraps return f(self, *args, **kwargs) File "/app/superset/databases/api.py", line 709, in test_connection TestConnectionDatabaseCommand(g.user, item).run() File "/app/superset/databases/commands/test_connection.py", line 145, in run raise DatabaseTestConnectionFailedError(errors) from ex superset.databases.commands.exceptions.DatabaseTestConnectionFailedError: [SupersetError(message='(builtins.NoneType) None\n(Background on this error at: http://sqlalche.me/e/13/dbapi)', error_type=<SupersetErrorType.GENERIC_DB_ENGINE_ERROR: 'GENERIC_DB_ENGINE_ERROR'>, level=<ErrorLevel.ERROR: 'error'>, extra={'engine_name': 'Azure Synapse', 'issue_codes': [{'code': 1002, 'message': 'Issue 1002 - The database returned an unexpected error.'}]})] ``` So, I tested some different connections string, the following two worked: `mssql+pymssql://<user>:<password>@<host>/?charset=utf8` `mssql+pymssql://<user>:<password>@<host>:<port>` However, when checking the Database schema on SQL Lab, it only shows the system tables:  It's not a permissions problem, because it works on Dbeaver! Queries also work, by specifying the complete path such as: `select * from db_name.dbo.table_name;` **The only problem is the fact that it is only displaying system tables and views.** #### How to reproduce the bug 1. Go to Databases tab 2. Create a new database connection using pymssql 3. By using the default connection string, you should receive an error message. 4. See error 5. Try using my suggested connection string, it may work, but you will only see system tables at the SQL Lab. ### Expected results Show all tables inside the database ### Actual results Only shows system tables, such as:  ### Environment - browser type and version: Chrome Version 110.0.5481.100 (Official Build) (x86_64), but the same happens for all browsers - superset version: `2.0.0` - lib version: `pymssql==2.2.7` - python version: `3.8` - node.js version: `node 16` - any feature flags active: ALERT_REPORTS, DASHBOARD_NATIVE_FILTERS, ENABLE_TEMPLATE_PROCESSING - My Superset is running via Kubernetes ### Checklist Make sure to follow these steps before submitting your issue - thank you! - [X] I have checked the superset logs for python stacktraces and included it here as text if there are any. - [ ] I have reproduced the issue with at least the latest released version of superset. - [X] I have checked the issue tracker for the same issue and I haven't found one similar. ### Additional context This is not a database we own, so some tests would require getting in contact with the external provider, something We wouldn't like to do at this moment. -- This is an automated message from the Apache Git Service.
