I am trying to get the correct info from an XML data type into regular scalar variables based on conditions, however I am having trouble getting the correct info back.
Here is the XML I am searching through:
<Loop2420>
<NM1>
<F98_1>PW</F98_1>
<F1065>2</F1065>
</NM1>
<N3>
<F166>81715 DOCTOR CARRE</F166>
</N3>
<N4>
<F19>INDIO</F19>
<F156>CA</F156>
<F116>92201</F116>
</N4>
</Loop2420>
<Loop2420>
<NM1>
<F98_1>45</F98_1>
<F1065>2</F1065>
</NM1>
<N3>
<F166>51250 MECCA AVE</F166>
</N3>
<N4>
<F19>COACHELLA</F19>
<F156>CA</F156>
<F116>92236</F116>
</N4>
</Loop2420>
Basically I need to get the numbers from <'F116'> but only if <'F98_1'> is equal to 'PW'.
I have tried:
declare #zip varchar(30)
select #zip = T.value('(F116)[1]','varchar(30)')
from #TransactionXML.nodes('/Loop2420/N4') Trans(T)
where T.value('(/Loop2420/NM1/F98_1)[1]','varchar(30)') = 'PW'
But that sometimes returns the value from <'F116'> even if <'F98_1'> is equal to '45'.
Any suggestions? Thanks.
Put the test in the XQuery itself and clamp it to the node you're checking:
SELECT #zip = T.value('(N4/F116)[1]', 'varchar(30)')
FROM #TransactionXML.nodes('/Loop2420') Trans(T)
WHERE T.exist('NM1/F98_1[text()="PW"]') = 1
If PW is not a static value, use the sql:variable() or sql:column() function to incorporate it in the query.

I have a logs message that I have to extract columns from with a sql query,
this how the message looks like:
"device=EOHCS-ZA-JIS-FW severity=high from=EOHCloudFAZ(FL1KVM0000005594) trigger=Syslog Critical System Alerts log="logver=54 itime=1528457940 devid=FG1K5D3I13800425 devname=FWJIS01 vd=95_LHC date=2018-06-08 time=13:34:55 logid=0100044546 type=event subtype=system level=information logdesc="Attribute configured" user="JoshuaK" ui="ha_daemon" action=Edit cfgtid=701760128 cfgpath="system.settings" cfgattr="gui-allow-unnamed-policy[disable->enable]" msg="Edit system.settings """
can someone give me an idea
I have a solution for SQL-Server, you could use PATINDEX and extract the log message.
Below is the code to extract from value
declare #input nVarchar(max),#from nVarchar(MAX)
declare #FromStart int,#FromEnd int
set #input='device=EOHCS-ZA-JIS-FW severity=high from=EOHCloudFAZ(FL1KVM0000005594) trigger=Syslog Critical System Alerts log="logver=54 itime=1528457940 devid=FG1K5D3I13800425 devname=FWJIS01 vd=95_LHC date=2018-06-08 time=13:34:55 logid=0100044546 type=event subtype=system level=information logdesc="Attribute configured" user="JoshuaK" ui="ha_daemon" action=Edit cfgtid=701760128 cfgpath="system.settings" cfgattr="gui-allow-unnamed-policy[disable->enable]" msg="Edit system.settings';
SET #FromStart=PATINDEX('%from=%',#input)+5;
SET #FromEnd=PATINDEX('% trigger=%',#input)-#FromStart;
SELECT #from=SUBSTRING(#input,#FromStart,#FromEnd)
SELECT #from
Note : use equivalent of PATINDEX for your corresponding DB server. Also note that this works only if the input string have parameters in a defined order.
I need to change the below query to be able to query any kind of tender item.
/Basket/CardTenderItem/Description
/Basket/CashTenderItem/Description
So
/Basket/WildcardTenderItem/Description
I have looked at various examples on but cannot them to bring back any results when running (happily admit to user error if can get working!)
SELECT
RETURN_ID
,SALE_ID,
,extractValue(xmltype(RETURNxml),'/Basket/CashTenderItem/NetValue')
,extractValue(xmltype(RETURNxml),'/Basket/CashTenderItem/Description')
FROM SPR361
WHERE return_id = '9999.0303|20170327224954|2063'
If you only want to match anything the ends with TenderItem, but doesn't have anything after that, you could be specific with substring checks:
SELECT
RETURN_ID
,SALE_ID
,extractValue(xmltype(RETURNxml),
'/Basket/*[substring(name(), string-length(name()) - 9) = "TenderItem"]/NetValue')
,extractValue(xmltype(RETURNxml),
'/Basket/*[substring(name(), string-length(name()) - 9) = "TenderItem"]/Description')
FROM SPR361
WHERE return_id = '9999.0303|20170327224954|2063'
If you never have any nodes with anything after that fixed string then #Shnugo's contains approach is easier, and in Oracle would be very similar:
...
,extractValue(xmltype(RETURNxml),
'/Basket/*[contains(name(), "TenderItem")]/NetValue')
,extractValue(xmltype(RETURNxml),
'/Basket/*[contains(name(), "TenderItem")]/Description')
I'm not sure there's any real difference between name() and local-name() here.
If a basket can have multiple child nodes (card and cash, or more than one of each) you could also switch to XMLTable syntax:
SELECT
s.RETURN_ID
,s.SALE_ID
,x.netvalue
,x.description
FROM SPR361 s
CROSS JOIN XMLTable(
'/Basket/*[contains(name(), "TenderItem")]'
PASSING XMLType(s.RETURNxml)
COLUMNS netvalue NUMBER PATH './NetValue'
, description VARCHAR(80) PATh './Description'
) x
WHERE s.return_id = '9999.0303|20170327224954|2063'
And it's overkill here maybe, but for more complicated tests you can use other XPath syntax, like:
CROSS JOIN XMLTable(
'for $i in /Basket/*
where contains($i/name(), "TenderItem") return $i'
PASSING XMLType(s.RETURNxml)
...
This is SQL-Server syntax and I cannot test, if this works with Oracle too, but I think it will. You can use XQuery function contains():
DECLARE #xml XML=
N'<root>
<abcTenderItem>test1</abcTenderItem>
<SomeOther>should not show up</SomeOther>
<xyzTenderItem>test2</xyzTenderItem>
</root>';
SELECT #xml.query(N'/root/*[contains(local-name(),"TenderItem")]')
only the elements with "TenderItem" in their names show up:
<abcTenderItem>test1</abcTenderItem>
<xyzTenderItem>test2</xyzTenderItem>
This is a unique problem..I think. So my goal is to input a variable and get a row from my column. Let me explain a little with the code im doing.
SELECT
pref.query('Database/text()') as PersonSkills,
pref.query('FillQuery/text()') as PersonSkills,
pref.query('TabText/text()') as PersonSkills,
pref.query('TooltipText/text()') as PersonSkills
FROM table CROSS APPLY
Tag.nodes('/Root/Configuration/TaskSelectorControl/QueueSelector') AS People(pref)
this works fine. However what I need to do is pass in the last part, the queue selector as a variables.
DECLARE #Xml XML
DECLARE #AttributeName VARCHAR(MAX) = 'QueueSelector'
SELECT
pref.query('Database/text()') as PersonSkills,
pref.query('FillQuery/text()') as PersonSkills,
pref.query('TabText/text()') as PersonSkills,
pref.query('TooltipText/text()') as PersonSkills
FROM table CROSS APPLY
Tag.nodes('/Root/Configuration/TaskSelectorControl[#Name=sql:variable("#AttributeName")]
') AS People(pref)
this doesnt work, any ideas why?
Well, I kinda lied. the bottom works, however it returns an empty dataset
/Root/Configuration/TaskSelectorControl/QueueSelector
is not equivalent to:
/Root/Configuration/TaskSelectorControl[#Name='QueueSelector']
The above XPath selects <TaskSelectorControl Name="QueueSelector">, not <QueueSelector> children of <TaskSelectorControl>.
You could either do this in XPath:
/Root/Configuration/TaskSelectorControl/*[local-name(.)=sql:variable("#AttributeName")]
Or it might be simpler to concat prior to evaluating:
'/Root/Configuration/TaskSelectorControl/' + #AttributeName
We have a source XML file that has an address node, and each node is supposed to have a zip_code node beneath in order to validate. We received a file that failed the schema validation because at least one node was missing it's zip_code (there were several thousand addresses in the file).
We need to find the elements that do not have a zip code, so we can repair the file and send an audit report to the source.
--declare #x xml = bulkcolumn from openrowset(bulk 'x:\file.xml',single_blob) as s
declare #x xml = N'<addresses>
<address><external_address_id>1</external_address_id><zip_code>53207</zip_code></address>
<address><external_address_id>2</external_address_id></address>
</addresses>'
declare #t xml = (
select #x.query('for $a in .//address
return
if ($a/zip_code)
then <external_address_id />
else $a/external_address_id')
)
select x.AddressID.value('.', 'int') AddressID
from #t.nodes('./external_address_id') x(AddressID)
where x.AddressID.value('.', 'int') > 0
GO
Really, it's the where clause that bugs me. I feel like I'm depending on a cast for a null value to 0, and it works, but I'm not really sure that it should. I tried a few variations with the .exist function, but I couldn't get the correct result.
If you just want to ensure that you are selecting address elements that have a zip_code element, then adjust your XPATH to include that criteria in a predicate filter:
/addresses/address[zip_code]
If you also want to ensure that the zip_code element also has a value, use a predicate filter for the zip_node to select those that have text() nodes:
/addresses/address[zip_code[text()]]
EDIT:
Actually, I'm looking for the
opposite. I need to identify the nodes
that don't have a zip, so we can
manually correct the source data.
So, if you want to identify all of the address elements that do not have a zip_code, you can specify it in the XPATH like this:
/addresses/address[not(zip_code)]
If you just want to locate those nodes that are missing their <zip_code> element, you could use something like this:
SELECT
ADRS.ADR.value('(external_address_id)[1]', 'int') as 'ExtAdrID'
FROM
#x.nodes('/addresses/address') as ADRS(ADR)
WHERE
ADRS.ADR.exist('zip_code') = 0
It uses the built-in .exist() method in XQuery to check the existence of a subnode inside an XML node.
I have a bunch of rows in a database that all contain an element that looks like the following
<ModuleData ModuleFieldGU="4dcdde21-40c6-4d1a-9fe1-1841935d3a68">
<DateTime>0001-01-01T00:00:00</DateTime>
<Boolean>false</Boolean>
<Int>0</Int>
<Varchar>Test District</Varchar>
<GUID>00000000-0000-0000-0000-000000000000</GUID>
<Modified>true</Modified>
</ModuleData>
I need to look across all of these and match where the varchar element/node is set to a certain value.
I've tried both of the followuing, and neither seem to be working for me
SELECT
Data.Element.value('(#Varchar)[1]', 'varchar(255)') as UserEmail
FROM
ModuleData
CROSS APPLY
XML_DATA.nodes('/ModuleData') AS Data(Element)
WHERE
Data.Element.value('(#Varchar)[1]', 'varchar(255)') = #UserEmail
and
SELECT
CAST(XML_DATA.query('data(/ModuleData[#Varchar])') as varchar(255)) as UserEmail
FROM
ModuleData
WHERE
XML_DATA.exist('/ModuleData[#Varchar = sql:variable("#UserEmail")]') = 1
but it isn't working. I'm not really up to speed with the finer points of using XQuery to get data out of XML. Can anyone point me in the correct direction?
The correct XPath should be:
/ModuleData/Varchar
Because it's an element, not an attribute.
