@AndriySvyryd did the changes as we discussed, take a look. (Note that this doesn't include creating our own ParameterDirection, I'll do that in a separate PR) |

@AndriySvyryd @ajcvickers one last design thought on this... This PR makes in/out parameters means "always both send and receive", as discussed. If, in the future, we implement optional sproc parameters with sentinel values, it would be a breaking change to change the meaning of in/out to "write only if the user set the property, read only if they didn't" (which is our regular SQL behavior). In other words, in order to allow the user to sometimes provide a value and sometimes not (in different commands) - today, without optional params/sentinels - we're making it so that their value is always sent and read back (in the same command).
I'm a bit concerned that we're painting ourselves into a corner; ideally, the write-and-read within the same command would be triggered by a separate opt-in, since it's probably really rare. Not merging this PR would mean users currently must choose either input or output, but not both, which doesn't seem too bad. If/when we have optional/sentinel parameters, they'd be able to do input/output without reading back values when they provide them.
But we've already discussed this too much... If you're guys this we should do this, I'm OK with it.
Closes #28704
