Sql SSMS连接未附加

我正在尝试做一个简单的连接，但它不起作用。下面是我的代码和测试数据。它没有将它们连接在一起，而是将它们添加到底部。任何帮助都将不胜感激。我尝试在一个连接和选择中完成所有操作，但无法使其工作，所以我尝试将其分解

    CREATE TABLE #inkoff
    ( 
            InvoiceDate varchar(50)
        ,   JobNumber varchar(50)
        ,   EstNum varchar(50)
        ,   Estimate varchar(50)
        ,   Actual varchar(50)
    )
    --This is an insert into select, but for testing purposes:
    INSERT INTO #inkoff (InvoiceDate, JobNumber, EstNum)
                        VALUES (20170101, '0001', 'E0001')
    INSERT INTO #inkoff (InvoiceDate, JobNumber, EstNum)
                        VALUES (20170201, '0002', 'E0002')
    INSERT INTO #inkoff (InvoiceDate, JobNumber, EstNum)
                        VALUES (20170301, '0003', 'E0003')
    INSERT INTO #inkoff (InvoiceDate, JobNumber, EstNum)
                        VALUES (20170401, '0004', 'E0004')
    --SELECT * FROM #inkoff
------------------------------------------------------------------------------------------------------------------------------------------------------------        
CREATE TABLE #inkest
    ( 
            EstNum varchar(50)
        ,   Estimate varchar(50)
    )
    --This is another insert into select but it is SELECT Distinct (EstimateNumber), Sum (Cost) as Estimate
    INSERT INTO #inkest (EstNum, Estimate)
        VALUES ('E0001', '100.25')
    INSERT INTO #inkest (EstNum, Estimate)
        VALUES ('E0002', '55.25')
    INSERT INTO #inkest (EstNum, Estimate)
        VALUES ('E0003', '75.26')
    INSERT INTO #inkest (EstNum, Estimate)
        VALUES ('E0004', '75.26')
    INSERT INTO #inkest (EstNum, Estimate)
        VALUES ('E0005', '100.01')                  
 --SELECT * FROM #inkest

 --Instead of appending them to the first four rows, it adds 5 rows to the bottom and doesn't join them up. 
 INSERT INTO #inkoff (Estimate) 
        SELECT A.Estimate FROM #inkest A 
        LEFT JOIN #inkoff  B    
        ON A.EstNum = B.EstNum 

SELECT * FROM #inkoff
SELECT * FROM #inkest

我怀疑您想要做的是

更新

，而不是插入，与此类似：

    update b
    set b.estimate = a.estimate
    from #inkest a left join #inkoff b on a.EstNum=b.EstNum

您应该查看

UPDATE

您是否检查了

INSERT

功能的文档？它会将新记录插入表中。谢谢。成功了。我不知道为什么我要加入。再次感谢。
