Hey all,

Some strange behaviour when using the preview connection.

Within the procedure I'm invoking an external rest endpoint using the sys.sp_invoke_external_rest_endpoint, which returns a JSON string, within SQL I then parse that into a table and return the result. The only way I can get it to work is to modify the proc:

Alter Procedure dbo.myHeadache 
 @url nvarchar(max)
 @query nvarchar(max)
AS
Begin

Select 
 'hello' as fieldName
 -- add other required fields

-- Replace the select statement with the sys.sp_invoke_external_rest_endpoint
-- After importing into PowerApps

End

After the first load in PowerApps I can then implement the external rest call by reverting the procedure. I've also tried:

modifying the procedure to use a flag to switch the return results from the sudo table to the parsed json table
calling the procedure from another procedure

I hope this saves someone some pain.
