SELECT node text values from xml document in TSQL OPENXML - sql-server

Question

I have a xml document I want to use to update values in a stored procedure. I can process the XML using OPENXML, but I'm confused about extracting the values I want. Each row in the xml is a product record and I want to create a variable for each property. Cell0 is the ID, Cell2 description etc
DECLARE #idoc int
DECLARE #doc varchar(1000)
SET #doc ='
<products>
<rows>
<row>
<cell>1</cell>
<cell>BALSAMO DERMOSCENT</cell>
<cell>1.00</cell>
<cell>0.00</cell>
<cell>18.00</cell>
<cell>18.00</cell>
<cell>8.00</cell>
<cell>427</cell>
<cell>No</cell>
</row>
<row>
<cell>2</cell>
<cell>BAYTRIL 150 MG 1 CPDO</cell>
<cell>1.00</cell>
<cell>0.00</cell>
<cell>3.50</cell>
<cell>3.50</cell>
<cell>8.00</cell>
<cell>57</cell>
<cell>No</cell>
</row>
</rows>
</products>'
--Create an internal representation of the XML document.
EXEC sp_xml_preparedocument #idoc OUTPUT, #doc
-- Execute a SELECT statement that uses the OPENXML rowset provider.
SELECT *
FROM OPENXML (#idoc, '/products/rows/row/cell',1)
with (Col1 varchar(29) 'text()')
Running the above query returns 1 record for each CELL in the xml. I want to be able to return 1 record per row with different columns for each cell, something like:-
Prod Description Qty
---------- -------------------- --------
1 BALSAMO DERMOSCENT 1.00
2 BAYTRIL 150 MG 1 CPDO 1.00
I'm using MSSQL 2008

Answer 1

I've come up with the following which does the job for me
DECLARE #idoc int
DECLARE #doc varchar(1000)
SET #doc ='
<products>
<rows>
<row>
<cell>1</cell>
<cell>BALSAMO DERMOSCENT</cell>
<cell>1.00</cell>
<cell>0.00</cell>
<cell>18.00</cell>
<cell>18.00</cell>
<cell>8.00</cell>
<cell>427</cell>
<cell>No</cell>
</row>
<row>
<cell>2</cell>
<cell>BAYTRIL 150 MG 1 CPDO</cell>
<cell>1.00</cell>
<cell>0.00</cell>
<cell>3.50</cell>
<cell>3.50</cell>
<cell>8.00</cell>
<cell>57</cell>
<cell>No</cell>
</row>
</rows>
</products>'
--Create an internal representation of the XML document.
EXEC sp_xml_preparedocument #idoc OUTPUT, #doc
-- Execute a SELECT statement that uses the OPENXML rowset provider.
SELECT *
FROM OPENXML (#idoc, '/products/rows/row',1)
with (pLineNo int 'cell[1]/text()',
pDesc varchar(50) 'cell[2]/text()',
pQty float 'cell[3]/text()',
pCost float 'cell[4]/text()',
pPvp float 'cell[5]/text()',
pTotal float 'cell[6]/text()',
pIva float 'cell[7]/text()',
pId int 'cell[8]/text()',
pnoFact varchar(5) 'cell[9]/text()')

Why use openxml on sql server 2008?
This is a better option (I used varchar(max) as the datatype, but enter whatever is applicable). Note you have to declare the variable as xml, not varchar.
SELECT
Row.Item.value('data(cell[1])', 'varchar(max)') As Prod,
Row.Item.value('data(cell[2])', 'varchar(max)') As Description,
Row.Item.value('data(cell[3])', 'varchar(max)') As Qty
FROM
#doc.nodes('//row') AS Row(Item)
Note: If you're doing this is a stored procedure you may have to include the following before the select statement:
SET ARITHABORT ON -- required for .nodes
If you must use openxml, at least clean it up when you're done:
exec sp_xml_removedocument #idoc
