sql server2008 企业版是支持cdc的,但是代码提示版本过低
尝试自己用源码编译后可以通过

@JackTianZhao Hi, sql server 2008 cann't pass all unit tests and version is too old. I don't suggest you to do this , maybe cause production accident.
hope ur great team can support this version!
希望能尽快支持,现在依然有不少老版本的在跑,这会让flink-cdc更宽容!!
hope flink can support this version!
Closing this issue because it was created before version 2.3.0 (2022-11-10). Please try the latest version of Flink CDC to see if the issue has been resolved. If the issue is still valid, kindly report it on Apache Jira under project Flink with component tag Flink CDC. Thank you!
