OFFSET 命令附近的语法不正确

为什么这不起作用并给我一个“偏移命令附近的语法不正确”错误

SELECT o.orderdate, o.orderid, o.empid, o.custid FROM Sales.Orders o
ORDER BY o.orderdate, o.orderid
OFFSET 50 ROWS
FETCH NEXT 25 ROWS ONLY;

我正在使用 SQL Server Express 2014

检查数据库兼容性级别。OFFSET是在SQL Server 2012中添加的，因此如果您的数据库处于2008兼容模式，则该关键字不可用。

查看或更改数据库的兼容级别 https://msdn.microsoft.com/en-us/library/bb933794.aspx

在 T-SQL 中你可以这样检查：

 USE AdventureWorks2012;  
 GO  

 SELECT compatibility_level  
 FROM sys.databases WHERE name = 'AdventureWorks2012';  
 GO

以下是兼容性级别列表，取自sp_dbcmptlevel 被弃用后如何检查 SQL Server 数据库兼容性？ https://stackoverflow.com/questions/1501596/how-to-check-sql-server-database-compatibility-after-sp-dbcmptlevel-is-deprecate:

 65 - SQL Server 6.5
 70 - SQL Server 7.0
 80 - SQL Server 2000
 90 - SQL Server 2005
100 - SQL Server 2008/R2
110 - SQL Server 2012
120 - SQL Server 2014
130 - SQL Server 2016
140 - SQL Server 2017

此外，Azure SQL数据仓库和并行数据仓库不支持OFFSET条款，从文档中可以看出ORDER BY https://learn.microsoft.com/en-us/sql/t-sql/queries/select-order-by-clause-transact-sql?view=sql-server-2017 clause:
