Official support for PostgreSQL, MySQL, SQLite, and SQL Server#2
Conversation
Closes real per-dialect parsing gaps so the four major engines are covered without introducing a dialect concept in the public API — the parser stays permissive and recognizes each syntax by shape: - SQL Server named parameters (@id, @p1) typed alongside $n and ?. - MySQL backtick-quoted identifiers (`` `col` ``) — a prior limitation note claiming this was impossible was wrong; TS allows escaping a backtick inside a template literal type. - SQL Server TOP N [PERCENT] clause, including TOP (n). - SQL Server OUTPUT clause (the RETURNING equivalent) for INSERT/UPDATE/ DELETE, with inserted./deleted. pseudo-table columns resolved correctly. - README: driver recipe for mssql, a database-support feature matrix, and updated limitations. New per-dialect regression suites under tests/. Also bumps the package version to 0.1.3.

How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.
