Pull request overview

This PR extends the SQL module’s SqlQuery activity to support pluggable query-result output formats beyond DataSet, enabling workflows to receive transformed result shapes (e.g., “RecordSet”) via registered result handlers.

Changes:

• Adds result-type handler abstractions (provider + factory + handler interface) and registers default DataSet / RecordSet handlers.
• Updates SqlQuery to select a result handler by a new ResultsType input and emit handled results.
• Introduces a new Elsa.Sql.Tests test project with unit tests for the DataSet and RecordSet handlers.

Reviewed changes

Copilot reviewed 16 out of 18 changed files in this pull request and generated 13 comments.

Closes #153

[KnibbsyMan]

Hi @veraw, This is a great idea!

If you're able to:

• Accept the license/cla.
• Review these comments and decide if they should be applied / removed.
• Update the SQL README.md with this new feature.

I'll happily merge this PR.

[veraw]

@KnibbsyMan Sorry for the delay.... Since I needed to get approval for the license/cla based on my involvement with my company.. which I have... but upon further thought on the issue (feature)... I have added the following issue as a more general /opt-in approach (see: elsa-workflows/elsa-core#7770) that if approved, would allow across-activity conversion support, rather than just specific to the SQL extension module. (I have a partially worked on approach, not finished, but as mentioned in the issue, would require enhancements to elsa-core, elsa-studio aswell as an opt in extension module)

Which I would see more beneficial, once implemented, than this PR. (Suggestion would be to not approve this PR, in favour of the more general approach)
