Description

SQL string looks something like "... WHERE [DividendId] IN @Ids ORDER BY [SecId];"

This caused error DAP206 Incorrect syntax near @Ids, but the code executes as expected without having the brackets around the IN parameter,

Should this be an Error or a Warning - if the code still works, it feels like a Warning, and the correction an advisory.

Research direction

Start by locating the DAP206 diagnostic implementation and any tests covering the missing brackets around an IN parameter. Reproduce the shown SQL case and compare the diagnostic behavior with the fact that execution succeeds. Done means the issue's requested Error-versus-Warning behavior is resolved and covered by a regression test.
