從TableB匹配更新TableA

Question

我有兩個表，兩個表的第一列都匹配，我需要使用TableB中的所有數據UPDATE TableA，僅在TableA.Column1和TableB.Column1匹配的情況下。 我非常難以解決如何使它工作的問題……TableA具有大約80多個列，而TableB具有大約100多個列。 我正在Microsoft Access中嘗試此操作。

表A

+---------+---------+---------+---------+---------+---------+
| Column1 | Column2 | Column3 | Column4 | ....... | ColumnX |
+---------+---------+---------+---------+---------+---------+
|    1    |  DataA  |         |  DataA  | ....... |         |
+---------+---------+---------+---------+---------+---------+
|    2    |  DataA  |         |  DataA  | ....... |         |
+---------+---------+---------+---------+---------+---------+
|    3    |  DataA  |         |  DataA  | ....... |         |
+---------+---------+---------+---------+---------+---------+
|    4    |  DataA  |         |  DataA  | ....... |         |
+---------+---------+---------+---------+---------+---------+
| ....... | ....... | ....... | ....... | ....... | ....... |
+---------+---------+---------+---------+---------+---------+
|    X    |  DataA  |         |  DataA  | ....... |         |
+---------+---------+---------+---------+---------+---------+

表B

+---------+---------+---------+---------+---------+---------+
| Column1 | Column2 | Column3 | Column4 | ....... | ColumnX |
+---------+---------+---------+---------+---------+---------+
|    1    |         |  DataB  |         | ....... |  DataB  |
+---------+---------+---------+---------+---------+---------+
|    2    |         |  DataB  |         | ....... |  DataB  |
+---------+---------+---------+---------+---------+---------+
|    3    |         |  DataB  |         | ....... |  DataB  |
+---------+---------+---------+---------+---------+---------+
|    4    |         |  DataB  |         | ....... |  DataB  |
+---------+---------+---------+---------+---------+---------+
| ....... | ....... | ....... | ....... | ....... | ....... |
+---------+---------+---------+---------+---------+---------+
|    X    |         |  DataB  |         | ....... |  DataB  |
+---------+---------+---------+---------+---------+---------+

表A的最終結果

+---------+---------+---------+---------+---------+---------+
| Column1 | Column2 | Column3 | Column4 | ....... | ColumnX |
+---------+---------+---------+---------+---------+---------+
|    1    |  DataA  |  DataB  |  DataA  | ....... |  DataB  |
+---------+---------+---------+---------+---------+---------+
|    2    |  DataA  |  DataB  |  DataA  | ....... |  DataB  |
+---------+---------+---------+---------+---------+---------+
|    3    |  DataA  |  DataB  |  DataA  | ....... |  DataB  |
+---------+---------+---------+---------+---------+---------+
|    4    |  DataA  |  DataB  |  DataA  | ....... |  DataB  |
+---------+---------+---------+---------+---------+---------+
| ....... | ....... | ....... | ....... | ....... | ....... |
+---------+---------+---------+---------+---------+---------+
|    X    |  DataA  |  DataB  |  DataA  | ....... |  DataB  |
+---------+---------+---------+---------+---------+---------+

到目前為止我嘗試過的...

我很快就放棄了的UNION ...似乎這只是給我一個查詢，在這里我需要使用TableB中的所有數據實際UPDATE TableA

並且...

UPDATE TableA ([Column1],[Column2],[Column3],[Column4], ....... [ColumnX])
SELECT [Column1],[Column2],[Column3],[Column4], ....... [ColumnX]
  FROM TableB
 WHERE (TableA.Column1 = TableB.Column2)

試過這個...

運行時錯誤'3144'：UPDATE語句中的語法錯誤

SQL = "   UPDATE tbleVendorData AS A " & _
      "     JOIN tbleOLD AS B " & _
      "       ON A.[Column1] = B.[Column1] " & _
      "      SET A.[Column14] = CONCAT(A.[Column14], B.[Column5])"

Answer 1

以下查詢可能有效：

UPDATE TableA 
INNER JOIN TableB 
 ON(TableA.Column1 = TableB.Column2)
SET 
    TableA.Column3 = TableB.column3,
    ...
    TableA.Columnx = TableB.columnx
Where TableA.Column1 = TableB.column1;

希望能幫助到你！

Answer 2

玩一下：

UPDATE TableA AS A JOIN TableB AS B ON A.Column1 = B.Column1 SET A.Column1 = CONCAT(A.Column1,B.Column1) ...

或在MSSQL中

UPDATE A SET A.[Column14] = A.[Column14] + B.[Column5] FROM tbleVendorData AS A JOIN tbleOLD AS B ON A.[Column1] = B.[Column1]

如果某個給定字段的值在一個表中沒有，而第二個表中的相應字段中沒有，則可以嘗試使用CONCAT（A.Column1，B.Column1）。 它並不聰明，但是比使用IF容易。

Answer 3

不幸的是，這些建議都不起作用。但是，在進行了深入挖掘之后，以下內容對我有用！

UPDATE TableA, TableB
   SET TableA.Column15= [TableB].[Column3]
 WHERE (([TableA].[Column1]=[TableB].[Column1]));
