mysql - 从 SQL Server 表中的分区检索数据

Question

我是 SQL Server 分区 的新手。我尝试了一些教程，最后我得到了 this基于它创建了一个分区，但问题是我无法像 MYSQL 查询中那样检索基于分区的数据

SELECT * FROM TABLE_NAME  PARTITION(partitionId)

并且还在 SQL Server 中尝试了这个查询

SELECT $PARTITION.partition_function (partition_function_id)

EDIT:

The picture shows the data in table I have created partition based on Date, I like to retrieve data based on partition name, which is if partition name is 20170203 I am excepting results on that date.

Answer 1

select * from TABLE_NAME
where $partition.fpartfunction(date) = 1

这将返回分区 1 中的所有数据。

如果你想从日期开始检索它，你可以按照下面的方式进行，

CREATE PARTITION FUNCTION PF_Date(date) AS RANGE LEFT FOR VALUES('2017-01-01','2018-01-01');

--first partition
SELECT *
FROM schema.table_name
WHERE key_column <= '2017-01-01';

--second partition
SELECT *
FROM schema.table_name
WHERE key_column > '2017-01-01' AND key_column <= '2018-01-01';

--last partition
SELECT *
FROM schema.table_name
WHERE key_column > '2018-01-01';
