n some tables in OMOP CDM PostgreSQL ddl.txt, two timestamps appear simultaneously, such as both visit_start_datetime and visit_end_datetime are timestamp. But only one timestamp can be used in each table in SQL Server. Can this be modified?
Thank you very much! Are there any difference else between the two version?
The SQL dialects are different in details (datatypes, keywords, function names), so if you’re using SQL Server, you’d probably want to use the scripts from the corresponding directory in the repo.
Thanks a lot!
