Update table via xml input - sql

Question

I have a stored proc that inserts new records in my 2008 SQL server table via xml input:
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)
This works great for inserting new rows, the thing i'm confused about is updating (via UPDATE statement) this same table with new xml input?
Table:
Id(PK) BoxNumber BinId
(bigint) (bigint) (int)
_______________________
1 12 334
2 12 445
3 12 776
4 16 223
5 16 669
Command to be used:
EXEC upd_Box #binIds='<Bins><id>7848</id><id>76554</id><id>71875</id></Bins>', #BoxId=12

Answer 1

Sorry for the delay. Here is the answer for your second part(this should work for both update and insert)
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
Let me know how it goes.

Answer 2

You can use the NODES method again.
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 3

Try this
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
Let me know how it goes.
