Select 同时区分和排序

Question

如何在 select 语句上使用 Distinct 以及 SQL Server

上的序列

我尝试了这个子查询，但运气不好，我得到了

的错误

NEXT VALUE FOR function is not allowed in check constraints, default objects, computed columns, views, user-defined functions, user-defined aggregates, user-defined table types, sub-queries, common table expressions, derived tables or return statements.

 Select Distinct (Select
                  Next Value for dbo.P_PM_TBlIF240_SEQ , 'PH70', LEFT(ToolID, LEN(ToolID) - 2) as TOOLID, UsedLife, GETDATE(), CURRENT_TIMESTAMP, 'PH70-TA' 
            From
                    Machine_ToolItem_Relationship ) from Machine_ToolItem_Relationship

谁能帮我解决这个问题？

解决谢谢@Nick.McDermaid我的最终查询是这样的。

Select
    Next Value for dbo.P_PM_TBlIF240_SEQ , 'PH70', LEFT(ToolID, LEN(a.ToolID) - 2) as TOOLID, a.UsedLife, GETDATE(), CURRENT_TIMESTAMP, 'PH70-TA' 
    from (Select
    Distinct  LEFT(ToolID, LEN(ToolID) - 2) as TOOLID, UsedLife 
    from Machine_ToolItem_Relationship) as a
