Maybe you can see this documentation:Reporting across scaled-out cloud databases (preview).

Elastic query also introduces a stored procedure that provides direct access to the shards. The stored procedure is called sp_execute _remote and can be used to execute remote stored procedures or T-SQL code on the remote databases. It takes the following parameters:

1. Data source name (nvarchar): The name of the external data source of type RDBMS.
2. Query (nvarchar): The T-SQL query to be executed on each shard.
3. Parameter declaration (nvarchar) - optional: String with data type definitions for the 4. parameters used in the Query parameter (like sp_executesql).
4. Parameter value list - optional: Comma-separated list of parameter values (like sp_executesql).

The sp_execute_remote uses the external data source provided in the invocation parameters to execute the given T-SQL statement on the remote databases. It uses the credential of the external data source to connect to the shardmap manager database and the remote databases.

Example:

 EXEC sp_execute_remote
        N'MyExtSrc',
        N'select count(w_id) as foo from warehouse'

It means that you can call the Functions and Stored Procedures of One database In another database, just need to modify the SQL statement.

Hope this helps.
