Thanks，but the article talked too little to help. Actually, it only told me that by using this code we would accumulate all records of which v_date was less than or equal to current row. But the question is, what will happen by the code below? (the field v_date is a string value with the format 'yyyy-MM-dd') Thanks!

It's for SQL Server, but the semantics should be similar. https://www.sqlpassion.at/archive/2015/01/22/sql-server-windowing-functions-rows-vs-range/ Alan.

I found it difficult to get an answer about this for hive. Hope there would be a more detailed help article about OVER clause at the Confluence. Thanks!
