根据非主键列更新INTO而不是INSERT INTO

Question

现在我知道没有UPDATE INTO这样的命令，但是有可能做类似的事情，而不是基于非主键列的INSERT INTO吗？

例如，我想检查给定人员是否已存在具有今天日期的记录。如果该值已经存在，则使用新数字更新记录，如果它不存在（比如说明天运行该脚本），则将其插入表中。

以下是我正在使用的代码;

if OBJECT_ID('dbo.Temp') IS NULL 
    create table [dbo].[Temp] (
        UserID int,
        FullName varchar(300),
        DocsInBatch int,
        NumReviewed int,
        Outstanding int,
        Relevant int,
        HighlyRelevant int,
        Irrelevant int,
        OutOfScope int,
        Question int,
        TechnicalQuestion int,
        LastUpdate date

        PRIMARY KEY (UserID)
    )
insert INTO [dbo].[Temp]
SELECT a.UserID,
        a.FullName, 
        a.DocsInBatch, 
        a.NumReviewed, 
        (a.DocsInBatch - a.NumReviewed) AS "Outstanding",
        a.Relevant,
        a.[Highly Relevant],
        a.[Irrelevant],
        a.[Out-Of-Scope],
        a.[Question],
        a.[Technical Question],
        GetDate()
        FROM
    (
            SELECT au.UserID as [UserID],
                    au.FullName, 
                    count(1) AS "DocsInBatch", 
                    count([Document1LR_Relevancy].[CoArtID]) AS "NumReviewed",
                    sum(case when [Document1LR_Relevancy].[1LR_Relevancy] = 'Relevant' then 1 else 0 end) as 'Relevant',
                    sum(case when [Document1LR_Relevancy].[1LR_Relevancy] = 'Highly Relevant' then 1 else 0 end) as 'Highly Relevant',
                    sum(case when [Document1LR_Relevancy].[1LR_Relevancy] = 'Irrelevant' then 1 else 0 end) as 'Irrelevant',
                    sum(case when [Document1LR_Relevancy].[1LR_Relevancy] = 'Out-Of-Scope' then 1 else 0 end) as 'Out-Of-Scope',
                    sum(case when [Document1LR_Relevancy].[1LR_Relevancy] = 'Question' then 1 else 0 end) as 'Question',
                    sum(case when [Document1LR_Relevancy].[1LR_Relevancy] = 'Technical Question' then 1 else 0 end) as 'Technical Question'
                from [EDDS1024194].[EDDSDBO].[Document] doc
            LEFT JOIN (
                        SELECT XXX.ArtifactID, co.Name AS [1LR_Relevancy], Co.ArtifactID [CoArtID]
                        FROM [EDDSDBO].[Document] AS XXX WITH (NOLOCK)
                            INNER JOIN [EDDSDBO].[ZCodeArtifact_1001288] AS ca WITH (NOLOCK)
                                ON XXX.[ArtifactID] = ca.[AssociatedArtifactID]
                            INNER JOIN [EDDSDBO].[Code] AS co WITH (NOLOCK)
                                ON ca.[CodeArtifactID] = co.[ArtifactID]
                        ) AS [Document1LR_Relevancy]
                ON doc.[ArtifactID] = [Document1LR_Relevancy].[ArtifactID]
            INNER JOIN [EDDS1024194].[EDDSDBO].[DocumentBatch] db on
                db.DocumentArtifactID = doc.ArtifactID
            INNER JOIN [EDDS1024194].[EDDSDBO].[Batch] bat on
                bat.ArtifactID = db.BatchArtifactID
            INNER JOIN [EDDS1024194].[EDDSDBO].[AuditUser] au on
                au.UserID = bat.AssignedTo
            GROUP BY au.FullName, au.UserID

)a
ORDER BY a.FullName

此代码有效。它每次运行时都会在表中插入新记录，但我不确定如何进行上述操作。
