This project contains a sample database that demostrates an issue with the way Roundhouse parses MySQL scripts that contain stored procedures. If that stored procedure ends with a trailing "DELIMITER" statement, the execution of that procedure will fail.
This is interesting because there's a lot of MySQL documentation that does exactly this!
The thinking here, I bet, is that they assume that you are typing their example into an interactive terminal. If you're writing a standalone script that will be executed in its own session then that trailing "DELIMITER" isn't necessary.
To demonstrate the issue, copy the "connection-settings-sample.ps1" file to "connection-settings.ps1" and then edit that file to connect to your MySQL server. With that set, run the "migrate.ps1" PowerShell script.
To see Roundhouse run without issue, comment out the last line of the "/sproc/select_best_person.sql" file.
