Syntax to read xml inside of a stored procedure - sql

I am passing into #xCriteria a XML parameter that looks like:
<?xml version="1.0" encoding="utf-8"?>
<searchParameters xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<includeInactive enabled="True" />
</searchParameters>
I know the xpath is: //includeInactive/#enabled
And have tried:
--determine if we include inactive users
DECLARE #isInactive AS bit
-- SELECT #isInactive = #xCriteria.value('(/includeInactive/#enabled', 'bit')
-- SET #isInactive = #xCriteria.query('/includeInactive/#enabled')
-- SELECT #isInactive.value('(/includeInactive/enabled)[1]', 'bit')
-- SELECT #isInactive = #xCriteria.query('/includeInactive/#enabled')
PRINT '#isInactive'
PRINT #isInactive
How can I fetch the boolean value?


You try like this:
DECLARE #isInactive AS BIT;
SELECT
#isInactive = CASE #param.value('(/searchParameters/includeInactive)[1]/#enabled', 'bit')
WHEN 1 THEN 0 ELSE 1
END
SELECT #isInactive;
You basically need to select the first ((....)[1]) <includeInactive> node inside the root node, and then get the #enabled attribute off that node.
And you need to clunky CASE expression, since your XML stores the value of enabled, while the variable you want to get is the exact opposite - #isInactive.

How to pass index value from a node in XML DML with SQL

Starting with XML DML in SQL Server, pretty fine at the moment, but I am facing this challenge. I need to iterate through some defined nodes in XML data stored in SQL Server.
Already check this as reference, it gives a clue but still I did not figure it out how to send a SQL variable as an index in XML DML Reference.
Suppose the following XML data:
<materials>
<est_mat>
<pos>20</pos>
<item>BOX</item>
<qty>0.004</qty>
</est_mat>
<est_mat>
<pos>30</pos>
<item>xxx-xxx-xxx01</item>
<qty>1</qty>
</est_mat>
<est_mat>
<pos>40</pos>
<item>xxx-xxx-xxx02</item>
<qty>1</qty>
</est_mat>
</materials>
So what I am looking is to iterate through all number of <est_mat> nodes and replace <pos> attribute starting from 10, then next node will be 20 and so on.
So far I have this :
--starting of code
declare #cnt int = 10
declare #totalchildren varchar(300)
declare #pos int = 1
--returns the number of nodes
SET #totalchildren = (SELECT (XMLData.value('count(/materials/est_mat)', 'int'))
FROM TABLE_XMLFiles
WHERE myref = 173)
WHILE #cnt < #totalchildren
BEGIN
--PRINT #cnt
UPDATE TABLE_XMLFiles
SET XMLData.modify('replace value of (/materials/est_mat/pos[sql:variable("#pos")])[[1]] with sql:variable("#cnt")')
WHERE myref = 173
SET #cnt = #cnt + 1
SET #pos = #pos + 10
END
--end of code
Error:
XQuery [BinControl_XMLFiles.XMLData.modify()]: The target of 'replace value of' must be a non-metadata attribute or an element with simple typed content, found 'element(pos,xdt:untyped) ?'
Question is: how I can send a SQL variable as an index position like this:
SET XMLData.modify('replace value of (/materials/est_mat/pos/text())[sql:variable("#pos")]
with sql:variable("#cnt")')
as the value which I am replacing it works by sending it this way with sql:variable("#cnt") - already tried it and works but I am still not figuring it out how to send a variable through the index context.
Thanks in advance for your attention.

Why not just ignore the exsting <pos>-element and re-build the XML?
DECLARE #xml XML=
N'<materials>
<est_mat>
<pos>20</pos>
<item>BOX</item>
<qty>0.004</qty>
</est_mat>
<est_mat>
<pos>30</pos>
<item>xxx-xxx-xxx01</item>
<qty>1</qty>
</est_mat>
<est_mat>
<pos>40</pos>
<item>xxx-xxx-xxx02</item>
<qty>1</qty>
</est_mat>
</materials>';
SELECT ROW_NUMBER() OVER(ORDER BY (SELECT NULL)) * 10 AS pos
,em.value(N'item[1]',N'nvarchar(max)') AS item
,em.value(N'qty[1]',N'decimal(16,4)') AS qty
FROM #xml.nodes(N'/materials/est_mat') AS A(em)
FOR XML PATH('est_mat'),ROOT('materials')
UPDATE Your follow-up question
(Please avoid chameleon questions!)
Your structure might be queried in two combined steps. One query picks out all existing nodes, which are not called <materials> and then adds the query I stated above as a sub-element.
Hint The appropriate date format within XML is ISO8601. Your value 02092017 is culture depending and therefore something you should avoid. Better 2017-02-09 or 2017-02-09T00:00:00 (If it's not the 2nd of September :-) )
DECLARE #xml XML=
N'<order>
<orderbook>
<date> 02092017 </date>
</orderbook>
<materials>
<est_mat>
<pos>20</pos>
<item>BOX</item>
<qty>0.004</qty>
</est_mat>
<est_mat>
<pos>30</pos>
<item>xxx-xxx-xxx01</item>
<qty>1</qty>
</est_mat>
<est_mat>
<pos>40</pos>
<item>xxx-xxx-xxx02</item>
<qty>1</qty>
</est_mat>
</materials>
</order>';
SELECT #xml.query(N'/order/*[local-name()!="materials"]') AS [*]
,(
SELECT ROW_NUMBER() OVER(ORDER BY (SELECT NULL)) * 10 AS pos
,em.value(N'item[1]',N'nvarchar(max)') AS item
,em.value(N'qty[1]',N'decimal(16,4)') AS qty
FROM #xml.nodes(N'order/materials/est_mat') AS A(em)
FOR XML PATH('est_mat'),ROOT('materials'),TYPE
)
FOR XML PATH(N'order');
Attention: The XML's inner order of nodes might be changed...

Passing irregular xml file to the stored procedure

I have a sample xml as follows. I am trying to get all or specific data and then insert into the my sql table which has the same columns representing the values coming from xml. I looked through some solutions but the xml files are not formatted like I have in here. Can you help me?

You can use an XML type and XML methods if you remove or modify the declaration. The SQL Server XML type only supports UCS-2 encoding and doesn't recognize "standalone". The example below uses string manipulation to tweak the declaration. You'll need to change the data types according to your actual column types and should specify an explicit column list on the INSERT statement. I omitted that in this example only because I didn't want to assume your actual table columns matched the element names in the XML.
DECLARE #xml xml;
DECLARE #xmlString nvarchar(MAX) = N'<?xml version="1.0" encoding="UTF-8" standalone="true"?>

First of all you need to get your value into a declare variable of type XML or into an XML-typed data table column. As your XML contains namespaces you have to declare them in a WITH XMLNAMESPACES first. You might use wildcard syntax (*:), but its better to be as specific as possible.
The .nodes() call navigates to the Level of <VehicleStatus>. All elements below are simply 1:1 and easy to read...
You can try it like this:
DECLARE #xml XML=
N'<VehicleStatusResponse xmlns:ns2=
"http://fms-standard.com/rfms/v1.0.0/xsd/common/position" xmlns="http://fms-standard.com/rfms/v1.0.0/xsd/status">

Retrieve all XML elements with the same prefix in SQL Server

I have an XML file in a format similar to:
<XML>
<Field1>100</Field1>
<Field2>200</Field2>
<Field3>300</Field3>
<Test>400</Test>
</XML>
I need to write a query that will get all of the element values that start with Field. So given the XML above the result should be
FieldVal
--------
100
200
300
I've tried the following but it does not work:
Select
xc.value('text()', 'int')
From
#XMLData.nodes('/XML/[starts-with(name(), ''Field'')]') As xt(xc)
NOTE: I am well aware that this task could be easily done if I reformatted my XML but unfortunately I have no control over the format of the XML.

One way is
declare #XMLData xml ='<XML>
<Field1>100</Field1>
<Field2>200</Field2>
<Field3>300</Field3>
<Test>400</Test>
</XML>'
Select
xc.value('.', 'int')
From #XMLData.nodes('/XML/*') As xt(xc)
WHERE xc.value('local-name(.)', 'varchar(50)') LIKE 'Field%'

Prefix name with special character and check contains instead.
declare #x xml ='<XML>
<Field1>100</Field1>
<Field2>200</Field2>
<Field3>300</Field3>
<Test>400</Test>
</XML>';
select t.n.value('.','varchar(100)')
from #x.nodes ('XML/*[contains(concat("$",local-name()),"$Field")]') t(n);

I think it's this what you are looking for:
DECLARE #xml XML=
'<XML>
<Field1>100</Field1>
<Field2>200</Field2>
<Field3>300</Field3>
<Test>400</Test>
</XML>';
SELECT Fld.value('.','int') AS FieldOnly
FROM #xml.nodes('/XML/*[substring(local-name(.),1,5)="Field"]') AS A(Fld)
Just because of the discussion in comments:
DECLARE #fldName VARCHAR(100)='Field';
SELECT Fld.value('.','int') AS FieldOnly
FROM #xml.nodes('/XML/*[substring(local-name(.),1,string-length(sql:variable("#fldName")))=sql:variable("#fldName")]') AS A(Fld)
Change the first line to "Test" (case sensitive!), and you'd get just the one row with 400...

Exporting a xml document from sql 2008

All
I have very little experience of xml, so please be gentle.
The situation is we use an application called dataswitch to take xml and process it into our ERP system via business objects.
The output I am trying to recreate is as follows from a sample xml document.
**<?xml version="1.0" encoding="Windows-1252" ?>
- <IssueDetails Language="05" CssStyle="" DecFormat="1" DateFormat="01" Role="01" Version="6.0.000">**
- <Item>
<Job>00000121</Job>
<NonStocked>N</NonStocked>
<Warehouse>RM</Warehouse>
<StockCode>BBMB100</StockCode>
<Line>00</Line>
<QuantityToIssue>1.000</QuantityToIssue>
</Item>
</IssueDetails>
So far I have worked on the For xml Path method to build my query and used the sp from Phil Factor to write the output
So far I have been successful creating an xml document which opens in the browser (many tries required!)
This is the output I have managed to create, please note the top lines are different
**<IssueDetails xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">**
- <Item>
<Job>00044816</Job>
<NonStocked>N</NonStocked>
<Warehouse>C2</Warehouse>
<StockCode>FG00707</StockCode>
<Line>00</Line>
<QuantityToIssue>400.000000000</QuantityToIssue>
</Item>
- <Item>
<Job>00044816</Job>
<NonStocked>N</NonStocked>
<Warehouse>C2</Warehouse>
<StockCode>FG00707</StockCode>
<Line>00</Line>
<QuantityToIssue>10.000000000</QuantityToIssue>
</Item>
</IssueDetails>
So my question is how do I get the top line in my output to be the same as the sample output?
My procedure is listed below
Declare
#XML_1 varchar (max),
#myXML varchar(max),
#myFile varchar (30),
#Path varchar (100)
set #XML_1=''
set #myFile ='MaterialIssuesTest.xml'
set #Path='D:\Temp\'
--Query database for materials
Set #XML_1 =#XML_1 + ( SELECT WJM.[Job]
,Case when WJM.[Warehouse]='**' then 'Y' else 'N' end as NonStocked
,WJM.[Warehouse]
,rtrim(LP.StockCode) as StockCode
,WJM.[Line]
,[UnitQtyReqd]*LP.LQtyComplete as QuantityToIssue
FROM [SysproCompanyR].[dbo].[WipJobAllMat] WJM
inner join CHC_Production.LabPostsAtMileOps LP On WJM.Job=LP.Job
Where WJM.Job in ('00044816')and (WJM.OperationOffset > LP.PrevOp
and WJM.OperationOffset<LP.LOperation)
FOR XML Path ('Item'),ROOT ('IssueDetails'), ELEMENTS XSINIL
)
set #myXML = LTRIM(rtrim(#XML_1))
--Debug print xml
Print #myXML
--Output xml to document
execute dbo.spWriteStringToFile #myXML, #Path, #myFile
GO

To get you first line, which is a child element of the main body you need to do a sub query like what I have done below. To get the attributes you need to name them with the # symbol, again in my example (formatting changes to aid me setting it out!):
SET #XML_1 =#XML_1 +
(
SELECT WJM.[Job],
(
SELECT '' AS '#Language',
'' AS '#CssStyle',
'' AS '#DecFormat',
'' AS '#DateFormat',
'' AS '#Role',
'' AS '#Version'
FROM YOURTABLENAME YTN
WHERE YTN.[SOMEFIELD] = WJM.[SOMEFIELD]
FOR XML PATH(''), TYPE
) AS 'IssueDetails'
,Case when WJM.[Warehouse]='**' then 'Y' else 'N' end as NonStocked
,WJM.[Warehouse]
,rtrim(LP.StockCode) as StockCode
,WJM.[Line]
,[UnitQtyReqd]*LP.LQtyComplete as QuantityToIssue
FROM [SysproCompanyR].[dbo].[WipJobAllMat] WJM
INNER JOIN CHC_Production.LabPostsAtMileOps LP ON WJM.Job = LP.Job
WHERE WJM.Job IN ('00044816') AND (WJM.OperationOffset > LP.PrevOp
AND WJM.OperationOffset<LP.LOperation)
FOR XML Path ('Item'), ROOT ('IssueDetails'), ELEMENTS XSINIL
)
I don't know where the data is coming from, so you will have to fill in the table name and the WHERE clause to join it to the data that you already have. That is assuming the data is a child of the data that you have already provided.
Bare in mind the syntax might not be quite correct as I am doing this from memory and there are several different variations to get this result.

Loop on XML in SQL Server

I have to query an XML to extract the data and put it into columns. This works perfectly. However, I want to include a loop because the structure in the XML is as follows:
<BlockOrderMessage>
<FlightOrder>
<Flight>
<FlightNr>5</FlightNr>
<AircraftType>A255</AircraftType>
</Flight>
<PositionOrders>
<PositionOrder Unit="Unit 5">
<UnitName>UnitName5</UnitName>
<CardColor>Blue</CardColor>
</PositionOrder>
<PositionOrder Unit='Unit 6">
<UnitName>UnitName6</UnitName>
<CardColor>Red</CardColor>
</PositionOrder>
</PositionOrders>
</FlightOrder>
</BlockOrderMessage>
There's always only one , but there can be more ... Now, I can generate the column (when knowing the amount of ) using following code:
DECLARE #Data XML
SET #Data =
'<?xml version="1.0" encoding="UTF-8"?>
<BlockOrderMessage xmlns="http://www...."
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.... file:/C:/Users/.....xsd">
<FlightOrder>
<Flight>
<FlightNr>FlightNr0</FlightNr>
<AircraftType>AircraftType0</AircraftType>
<PositionOrders>
<PositionOrder Unit="Unit 5">
<UnitName>UnitName5</UnitName>
<CardColor>Blue</CardColor>
</PositionOrder>
<PositionOrder Unit="Unit 6">
<UnitName>UnitName6</UnitName>
<CardColor>Red</CardColor>
</PositionOrder>
</PositionOrders>
</FlightOrder>
</BlockOrderMessage>'
;WITH XMLNAMESPACES (DEFAULT 'http://www....')
SELECT #Data.value('(/BlockOrderMessage/FlightOrder/Flight/FlightNr)[1]','VARCHAR(20)') AS 'FlightNr',
#Data.value('(/BlockOrderMessage/FlightOrder/Flight/AircraftType)[1]','VARCHAR(20)') AS 'AircraftType',
#Data.value('(/BlockOrderMessage/FlightOrder/PositionOrders/PositionOrder/#Unit)[1]','VARCHAR(30)') AS 'PosOrder1_Unit ',
#Data.value('(/BlockOrderMessage/FlightOrder/PositionOrders/PositionOrder/UnitName)[1]','VARCHAR(30)') AS 'PosOrder1_UnitName',
#Data.value('(/BlockOrderMessage/FlightOrder/PositionOrders/PositionOrder/CardColor)[1]','VARCHAR(30)') AS 'PosOrder1_CardColor',
#Data.value('(/BlockOrderMessage/FlightOrder/PositionOrders/PositionOrder[2]/#Unit)[1]','VARCHAR(30)') AS 'PosOrder2_Unit',
#Data.value('(/BlockOrderMessage/FlightOrder/PositionOrders/PositionOrder[2]/UnitName)[1]','VARCHAR(30)') AS 'PosOrder2_UnitName',
#Data.value('(/BlockOrderMessage/FlightOrder/PositionOrders/PositionOrder[2]/CardColor)[1]','VARCHAR(30)') AS 'PosOrder2_CardColor'
But I want to insert a loop for the PositionOrder bit, I tried the following code (only the last part, since the rest stays the same):
;WITH XMLNAMESPACES (DEFAULT 'http://www....')
SELECT #Data.value('(/BlockOrderMessage/FlightOrder/Flight/FlightNr)[1]','VARCHAR(20)') AS 'FlightNr',
#Data.value('(/BlockOrderMessage/FlightOrder/Flight/AircraftType)[1]','VARCHAR(20)') AS 'AircraftType'
DECLARE #counter INT
SET #counter = 1
WHILE (#Data.value('(/BlockOrderMessage/FlightOrder/PositionOrders/PositionOrder/#Unit)[1]') IS NOT NULL)
BEGIN
;WITH XMLNAMESPACES (DEFAULT 'http://www....')
SELECT #Data.value('(/BlockOrderMessage/FlightOrder/PositionOrders/PositionOrder/#Unit)[1]','VARCHAR(30)') AS 'PosOrder_#counter_Unit ',
#Data.value('(/BlockOrderMessage/FlightOrder/PositionOrders/PositionOrder/UnitName)[1]','VARCHAR(30)') AS 'PosOrder_#counter_UnitName',
#Data.value('(/BlockOrderMessage/FlightOrder/PositionOrders/PositionOrder/CardColor)[1]','VARCHAR(30)') AS 'PosOrder_#counter_CardColor'
SET #counter = #counter +1
END
GO
Now, I have the following problems with this loop and the result of my query:
The results of the query for the PositionOrder are all NULL, this wasn't the case when I did it without loops.
I get two tables as query result, but I want them in one table. I tried to do it so I only use one SELECT statement, but I can't get the code right.
I want the name of the column to show the counter number: So if we are in the second loop, we want the name of the column to be PosOrder_2_..., now it shows PosOrder_#counter_...
Does anybody know what I am doing wrong or how I should fix this problem?
Thanks in advance!

Are you looking for something like this?
DECLARE #Flights XML = '<BlockOrderMessage>
<FlightOrder>
<Flight>
<FlightNr>5</FlightNr>
<AircraftType>A255</AircraftType>
</Flight>
<PositionOrders>
<PositionOrder Unit="Unit 5">
<UnitName>UnitName5</UnitName>
<CardColor>Blue</CardColor>
</PositionOrder>
<PositionOrder Unit="Unit 6">
<UnitName>UnitName6</UnitName>
<CardColor>Red</CardColor>
</PositionOrder>
</PositionOrders>
</FlightOrder>
</BlockOrderMessage>'
SELECT
FlightNr = FltOrder.value('(Flight/FlightNr)[1]', 'int'),
AircraftType = FltOrder.value('(Flight/AircraftType)[1]', 'varchaR(100)'),
PosOrderUnit = PosOrder.value('#Unit', 'varchar(50)'),
PosOrderUnitName = PosOrder.value('(UnitName)[1]', 'varchar(50)'),
PosOrderCardColor = PosOrder.value('(CardColor)[1]', 'varchar(50)')
FROM
#Flights.nodes('/BlockOrderMessage/FlightOrder') AS XTbl(FltOrder)
CROSS APPLY
FltOrder.nodes('PositionOrders/PositionOrder') AS XTbl2(PosOrder)
This would produce an output something like this:
Basically, it grabs the "base" data from the <BlockOrderMessage> / <FlightOrder> node and displays those in columns 1 & 2, and then it cross applies all subnodes <PositionOrders> / <PositionOrder> inside that <FlightOrder> node and extracts the remaining information from those subnodes (any number of them).
