PortalDB database connection is dialect

Hi @kamya7! I'm Dosu and I’m helping the superset team.

The "dialect" error you're seeing when trying to connect your "PortalDB" database typically means the required database driver is not installed in your Superset environment.

Superset uses SQLAlchemy under the hood, and each database type needs a specific Python driver package installed. Without it, Superset can't recognize the dialect in your connection URI.

To fix this:

1. Identify your database type — What type of database is "PortalDB"? (PostgreSQL, MySQL, SQL Server, Oracle, etc.)

2. Install the appropriate driver. For example [1]:

   pip install psycopg2        # PostgreSQL
   pip install mysqlclient     # MySQL
   pip install pymssql          # SQL Server
   pip install cx-Oracle        # Oracle

3. Use the correct SQLAlchemy URI format when adding the connection:

   dialect+driver://username:password@host:port/database
   

   For example: postgresql+psycopg2://user:pass@host:5432/PortalDB

4. If using Docker, add the driver to docker/requirements-local.txt [1]:

   echo "psycopg2-binary" >> ./docker/requirements-local.txt

After installing the driver, restart Superset and try the connection again.

Could you share what type of database "PortalDB" is and what SQLAlchemy URI you're using? That would help me give you the exact driver and URI format you need.

It is a PostgreSQL database. @dosu

Since it's a PostgreSQL database, here's what you need:

1. Install the PostgreSQL driver (if not already installed):

pip install psycopg2

Or if you're using Docker, add to docker/requirements-local.txt:

psycopg2-binary

2. Use this SQLAlchemy URI format when adding the database connection in Superset:

postgresql+psycopg2://username:password@host:5432/PortalDB

Replace username, password, host, and 5432 (if your port differs) with your actual database credentials.

3. Restart Superset after installing the driver.

If you're still seeing the dialect error after this, could you share the exact SQLAlchemy URI you're entering (with the password redacted) and the full error message? That will help pinpoint the issue.

psycopg2 is already installed @dosu

Hi! Were you able to try the steps I suggested earlier? To recap for your PostgreSQL "PortalDB" connection:

1. Install the driver: pip install psycopg2 (or psycopg2-binary for Docker)
2. Use this URI format: postgresql+psycopg2://username:password@host:5432/PortalDB
3. Restart Superset

If you're still running into issues, please share:

• The exact SQLAlchemy URI you're entering (with the password redacted)
• The full error message
• Whether you're running Superset via Docker or a local pip install

Happy to help further once I have more details!
