Oracle NoSQL数据库中的BETWEEN和dates运算符，怎么办？

Question

我想使用 BETWEEN 操作在 nosql 数据库中进行查询？我想做这样的事情：

SELECT * FROM table 
WHERE column_timestamp BETWEEN '2021-01-01'
AND '2021-12-31'

如何在 NoSQL 数据库中执行此查询？支持 BETWEEN 吗？

Answer 1

在你的情况下，因为你的列似乎是时间戳，你需要将时间戳值转换为 TIMESTAMP 类型。然后您只需使用 <= 和 >= 运算符。

在查询仅提供时间的日期 w/o 时要小心。这是一个使用 <, <=, >=, >.

的测试用例


I've inserted 3 rows :

    2021-12-01T00:00:00Z
    2021-12-31T00:00:00Z
    2021-12-31T23:59:59Z

SELECT * FROM TEST
where date > CAST("2021-12-01" as timestamp) and date < CAST("2021-12-31" as timestamp)

no rows selected

SELECT * FROM TEST
where date >= CAST("2021-12-01" as timestamp) and  date <= CAST("2021-12-31" as timestamp)

2 rows : 2021-12-01T00:00:00Z and 2021-12-31T00:00:00Z

SELECT * FROM TEST
where date >= CAST("2021-12-01T00:00:00" as timestamp)and  date <= CAST("2021-12-31T23:59:59" as timestamp)

3 rows : 2021-12-01T00:00:00Z , 2021-12-31T00:00:00Z and 2021-12-31T23:59:59Z

SELECT * FROM TEST
where date >= CAST("2021-12-01" as timestamp) and  date < CAST("2022-01-01" as timestamp) 

3 rows : 2021-12-01T00:00:00Z , 2021-12-31T00:00:00Z and 2021-12-31T23:59:59Z
