How do I remove the "JSON_" key in front of responses that were formatted with "FOR JSON PATH"

I’m executing a stored procedure which contains a select statement that uses for json path, root('error') and returns info if an error was raised.

I get this: {JSON_F52E2B61-18A1-11d1-B105-00805F49916B: '{"error":[{"ErrorNumber":50…" Instead of this: '{"error":[{"ErrorNumber":50…"

Is there a driver option to remove that exterior “JSON_” wrapper?

JSON_F52E2B61-18A1-11d1-B105-00805F49916B is the column name that SQL Server uses to send back JSON data, and as you noticed, the data is sent back as a regular string.

If you want to actually use this data in your application, you need to pass the string to JSON.parse as part of your query result handling. Automatic handling for this won’t be added to tedious, because we can’t know what the user’s intentions are, and serializing JSON is a rather expensive operation.

Please let us know if you have any further questions. 🙇‍♂️

Hi @NamedArray,Thank you for all the details. Just run a query using Sql Server Management Studio with a ‘for Json’ key word : “select colname from table for json path” . In my result set, it also has a ‘JSON_’ prefix. Could this be a common behavior for this key word, and not caused by tedious? This is screen shot for my output :

I also found a page from Microsoft doc that related to this: https://docs.microsoft.com/en-us/sql/relational-databases/json/format-query-results-as-json-with-for-json-sql-server?view=sql-server-ver15 . The examples in this page also includes the ‘JSON_’ prefix.
