Previously, the importer rejected these scripts because it couldn’t handle custom statement delimiters.

The updated parser identifies the complete procedure as a single statement before passing it to the native MySQL connection.

I tested the parser with Swift, including a stored procedure containing multiple SQL statements. The parser test passed. However, I haven’t compiled the complete macOS application or tested importing against a live MySQL server.
