Question

我有一个存储过程，它通过xml输入在我的2008 SQL服务器表中插入新记录：

CREATE PROCEDURE ins_AddBinsToBox
@BoxId          BIGINT,
@BinIds         XML
AS
BEGIN

INSERT INTO WebServiceBoxDetails 
(
  BinId,
  BoxId 
)
SELECT 
  ParamValues.ID.value('.','VARCHAR(20)'),
  @BoxId  
FROM 
  @binIds.nodes('/Bins/id') AS ParamValues(ID)

这非常适合插入新行，我很困惑的是更新（通过UPDATE语句）这个表与新的xml输入？

表：

Id(PK)    BoxNumber  BinId
(bigint)  (bigint)   (int)
_______________________
1           12         334
2           12         445
3           12         776
4           16         223
5           16         669

要使用的命令：

EXEC upd_Box @binIds='<Bins><id>7848</id><id>76554</id><id>71875</id></Bins>', @BoxId=12

Answer 1

您可以再次使用NODES方法。

UPDATE WebServiceBoxDetails
SET BinID = ParamValues.ID.value('@BinID','VARCHAR(20)')
FROM
 @bindIDs.nodes('/Bins/id') AS ParamValues(ID)
 JOIN WebServiceBoxDetails w ON w.ID = ParamValues.ID.value('@id','VARCHAR(20)')
 WHERE w.BoxNumber = @BoxID

Answer 2

试试这个

DECLARE @binIds AS XML = '<Bins><id>7848</id><id>76554</id><id>71875</id></Bins>'
DECLARE @id INT
DECLARE @newid INT
DECLARE @count INT = 1
DECLARE @BinIdTable TABLE(RowNumber INT, BinId INT) 

INSERT @BinIdTable(RowNumber, BinId)
SELECT ROW_NUMBER() OVER(ORDER BY ID), ParamValues.ID.value('.','INT')
FROM
 @binIds.nodes('/Bins/id') AS ParamValues(ID)


DECLARE MyCursor CURSOR FOR
 SELECT id FROM WebServiceBoxDetails WHERE BoxNumber = 12 ORDER BY id

 OPEN MyCursor

 FETCH NEXT FROM MyCursor
 INTO @id

 WHILE @@FETCH_STATUS = 0
 BEGIN

    SELECT @newid =  B.BinId
    FROM @BinIdTable B
        WHERE RowNumber = @count

    UPDATE WebServiceBoxDetails
        SET BinId = @newid
        WHERE Id = @id

    SET @count = @count + 1
    FETCH NEXT FROM MyCursor 
    INTO @id
 END
 CLOSE MyCursor
 DEALLOCATE MyCursor

让我知道它是怎么回事。

Answer 3

抱歉延误。以下是第二部分的答案（这应该适用于更新和插入）

DECLARE @binIds AS XML = '<Bins><id>44</id><id>55</id><id>66</id><id>77</id></Bins>'
DECLARE @id INT
DECLARE @newid INT
DECLARE @count INT = 1
DECLARE @BinIdTable TABLE(RowNumber INT, BinId INT) 
DECLARE @BoxNumber INT = 12
DECLARE @RowCount INT = 0

INSERT @BinIdTable(RowNumber, BinId)
SELECT ROW_NUMBER() OVER(ORDER BY ID), ParamValues.ID.value('.','INT')
FROM
 @binIds.nodes('/Bins/id') AS ParamValues(ID)

SELECT @RowCount = COUNT(*) FROM @BinIdTable

DECLARE MyCursor CURSOR FOR
 SELECT id FROM WebServiceBoxDetails WHERE BoxNumber = @BoxNumber ORDER BY id

 OPEN MyCursor

 FETCH NEXT FROM MyCursor
 INTO @id

 WHILE @@FETCH_STATUS = 0
 BEGIN

    SELECT @newid =  B.BinId
    FROM @BinIdTable B
        WHERE RowNumber = @count

    UPDATE WebServiceBoxDetails
        SET BinId = @newid
        WHERE Id = @id

    SET @count = @count + 1
    FETCH NEXT FROM MyCursor 
    INTO @id
 END
 CLOSE MyCursor
 DEALLOCATE MyCursor

 IF @RowCount >= @count
 BEGIN

    INSERT INTO WebServiceBoxDetails
    SELECT @BoxNumber, BinId 
        FROM @BinIdTable
        WHERE RowNumber >= @count

 END
