How to use only 1 parameter to switch different database connections rather than 2?
Hello everyone,
Based on many related helpful posts changing connections by using 2 parameters (just like this one ) but I faced to this task when I have theses Azure SQL databases with different URL and db-name:
| Name | Stage | Server URL |
| dev | Development | dev.database.windows.net |
| uat | Test | uat.database.windows.net |
| prod | Production | prod.database.windows.net |
How to use only 1 parameter to changing datasource which corresponds to each stage of the development lifecycle?
Many thanks to you guys
When you connect to Azure SQL databases, Power Query uses Sql.Database function. It requires server and database as two separate parameters. So it seems not possible to use only one parameter to switch the data source.
Sql.Database(server as text, database as text, optional options as nullable record) as table
If you use Odbc.DataSource, it may be possible to use only one parameter as it only requires connectionString. I haven't tested this yet. However ODBC connector only supports Import mode and the query performance is not as well as the SQL Server database connector.

If you found this post helpful, please give Kudos CThis is not the solution for my problem, I mean yes we can use parameter but in my problem we have separate different servers, different tables and I want to switch between them by only 1 parameter (that is the Stage parameter which ties pair server and table for each stage as I described in the table above). This is the idea and I don't know how to do it?
Thanks
