For example, the `SqlAlterCatalog` code block in `parserImpls.ftl` will be fleshed out with Java code. The last part of that code block actually calls the `SqlAlterCatalog` Java constructor referenced here. So the `setProps` and `resetProps` are passed in from the parsed SQL command. -- This is an automated message from the Apache Git Service.
