What kind of input is required for the Open SQL connection action?

The Open SQL connection action in Power Automate requires a connection string as input. A connection string encapsulates the necessary information for establishing a connection to a database. This includes details such as the database server's location, the database name, authentication credentials, and any additional parameters needed for the connection.

Using a connection string is essential because it provides all the context the application requires to successfully interact with the specific database environment. Without this, the action would be unable to identify where to connect or how to authenticate.

While SQL statements, lists of tables, or SQL connection variables may be relevant in the context of database interactions, they are not the necessary inputs for initiating a connection. SQL statements would be used for querying or modifying data once a connection is established, tables provide structural information about the database, and connection variables typically hold connection details after a connection has been initialized, rather than being used to create the connection itself.
