Getting nth Element from last in a xml in Sql Server

Getting nth Element from last in a xml in Sql Server - sql

Please consider this XML:
<Employees>
<Person>
<ID>1000</ID>
<Name>Nima</Name>
<LName>Agha</LName>
</Person>
<Person>
<ID>1001</ID>
<Name>Ligha</Name>
<LName>Ligha</LName>
</Person>
<Person>
<ID>1002</ID>
<Name>Jigha</Name>
<LName>Jigha</LName>
</Person>
<Person>
<ID>1003</ID>
<Name>Aba</Name>
<LName>Aba</LName>
</Person>
</Employees>
I want to write a function that gets a number, and then I get nth Person element, and Name. For example if 0 pass to my function I return Aba, if 1 pass to my function I return Jigha.

This should work. Set the value of the #index variable as the number of the record to find, relative to the end of the list:
declare #index int = 1
declare #xml xml = '<Employees>
<Person>
<ID>1000</ID>
<Name>Nima</Name>
<LName>Agha</LName>
</Person>
<Person>
<ID>1001</ID>
<Name>Ligha</Name>
<LName>Ligha</LName>
</Person>
<Person>
<ID>1002</ID>
<Name>Jigha</Name>
<LName>Jigha</LName>
</Person>
<Person>
<ID>1003</ID>
<Name>Aba</Name>
<LName>Aba</LName>
</Person>
</Employees>'
select t2.person.value('(Name/text())[1]','varchar(50)')
from #xml.nodes('Employees/Person[position()=(last()-sql:variable("#index"))]') as t2(person)

PLSQL - REGEXP_SUBSTR Remove XML Tags

I currently have a payload that was generated by oracle xml gateway that I need to pull some exact information out. The payload information is store within a db table meaning that I am attempting to us regexp_substr to accomplish this task.
This is the tag that is in the middle of the XML document
<IDCODE>S2200</IDCODE>

REGEX that I am using in the query
TRIM(regexp_substr(ed.payload, '?.+(</IDCODE>)')) Store_NUM,
TRIM(regexp_substr(ed.payload, '(^IDCODE)?.+(</IDCODE>)')) Store_Number
The Outcome that I am receiving from the above SQL regexp_substr. The issue is that I have made it to the correct tab but I can't figure out how to strip the \<IDCODE> and the \</IDCODE> for the output
-Field can have 4 or 5 chars
-letters or numbers
<IDCODE>S2200</IDCODE> Store_NUM
<IDCODE>S2200</IDCODE> Store_Number

I believe you are looking for this if I am understanding you correctly. Return everything in the group between the tags.
SELECT REGEXP_SUBSTR('<IDCODE>S2200</IDCODE>', '<IDCODE>(.*)</IDCODE>', 1, 1, NULL, 1) Store_Number

Extracting XML data using SQL

I would like to be able to extract specific data from a XML type using Oracle in my example for the customer named "Arshad Ali"
This is my xml data that was inserted:
<Customers>
<Customer CustomerName="Arshad Ali" CustomerID="C001">
<Orders>
<Order OrderDate="2012-07-04T00:00:00" OrderID="10248">
<OrderDetail Quantity="5" ProductID="10" />
<OrderDetail Quantity="12" ProductID="11" />
<OrderDetail Quantity="10" ProductID="42" />
</Order>
</Orders>
<Address> Address line 1, 2, 3</Address>
</Customer>
<Customer CustomerName="Paul Henriot" CustomerID="C002">
<Orders>
<Order OrderDate="2011-07-04T00:00:00" OrderID="10245">
<OrderDetail Quantity="12" ProductID="11" />
<OrderDetail Quantity="10" ProductID="42" />
</Order>
</Orders>
<Address> Address line 5, 6, 7</Address>
</Customer>
<Customer CustomerName="Carlos Gonzlez" CustomerID="C003">
<Orders>
<Order OrderDate="2012-08-16T00:00:00" OrderID="10283">
<OrderDetail Quantity="3" ProductID="72" />
</Order>
</Orders>
<Address> Address line 1, 4, 5</Address>
</Customer>
</Customers>
</ROOT>
using get clob I was able to extract all of the customers.
Was wondering if anyone could help me extract data for a specific customer.. tried using the following but was unsuccessful
SELECT extract(OBJECT_VALUE, '/root/Customers') "customer"
FROM mytable2
WHERE existsNode(OBJECT_VALUE, '/customers[CustomerName="Arshad Ali" CustomerID="C001"]')
= 1;

The case and exact names of the XML nodes matter:
SELECT extract(OBJECT_VALUE,
'/ROOT/Customers/Customer[#CustomerName="Arshad Ali"][#CustomerID="C001"]') "customer"
FROM mytable2
WHERE existsnode (OBJECT_VALUE,
'/ROOT/Customers/Customer[#CustomerName="Arshad Ali"][#CustomerID="C001"]') = 1
db<>fiddle
If you only want to search by name then only use that attribute:
SELECT extract(OBJECT_VALUE,
'/ROOT/Customers/Customer[#CustomerName="Arshad Ali"]') "customer"
FROM mytable2
WHERE existsnode (OBJECT_VALUE,
'/ROOT/Customers/Customer[#CustomerName="Arshad Ali"]') = 1
But extract() and existsnode() are deprecated; use xmlquery() and xmlexists() instead:
SELECT xmlquery('/ROOT/Customers/Customer[#CustomerName="Arshad Ali"][#CustomerID="C001"]'
passing object_value
returning content) "customer"
FROM mytable2
WHERE xmlexists('/ROOT/Customers/Customer[#CustomerName="Arshad Ali"][#CustomerID="C001"]'
passing object_value)

Sql return results as xml

Given this data:
FName Lname ApartmentNumber
-----------------------------------
David Shumer 1
John Deer 1
Mark Ratz 2
Steven Styer 2
I would like to return it as xml, so I did this:
select * from Table1
for xml raw('person'), root('PeopleInApartment'), elements
And I got this result
<PeopleInApartment>
<Person>
<FName>David</FName>
<LName>Shumer</LName>
<ApartmentNumber>1</ApartmentNumber>
</Person>
<Person>
<FName>John</FName>
<LName>Deer</LName>
<ApartmentNumber>1</ApartmentNumber>
</Person>
<Person>
<FName>Mark</FName>
<LName>Ratz</LName>
<ApartmentNumber>2</ApartmentNumber>
</Person>
<Person>
<FName>Steven</FName>
<LName>Styer</LName>
<ApartmentNumber>2</ApartmentNumber>
</Person>
</PeopleInApartment>
Is it possible to group people by apartment so the result would look like this?:
<Apartments>
<PeopleInApartment>
<Person>
<FName>David</FName>
<LName>Shumer</LName>
<ApartmentNumber>1</ApartmentNumber>
</Person>
<Person>
<FName>John</FName>
<LName>Deer</LName>
<ApartmentNumber>1</ApartmentNumber>
</Person>
</PeopleInApartment>
<PeopleInApartment>
<Person>
<FName>Mark</FName>
<LName>Ratz</LName>
<ApartmentNumber>2</ApartmentNumber>
</Person>
<Person>
<FName>Steven</FName>
<LName>Styer</LName>
<ApartmentNumber>2</ApartmentNumber>
</Person>
</PeopleInApartment>
</Apartments>

Sql solution. Note subquery must depend only on outer columns in the GROUP BY, t1.ApartmentNumber specifically.
select t1.ApartmentNumber
, (select t2.FName, t2.Lname
from Table1 t2
where t2.ApartmentNumber = t1.ApartmentNumber
for xml path('Person'), type
) as PeopleInApartment
from Table1 t1
group by ApartmentNumber
for xml path('Apartment'), root('Apartments'), elements
Returns data apartment - wise
<Apartments>
<Apartment>
<ApartmentNumber>1</ApartmentNumber>
<PeopleInApartment>
<Person>
<FName>David </FName>
<Lname>Shumer</Lname>
</Person>
<Person>
<FName>John </FName>
<Lname>Deer </Lname>
</Person>
</PeopleInApartment>
</Apartment>
<Apartment>
<ApartmentNumber>2</ApartmentNumber>
<PeopleInApartment>
<Person>
<FName>Mark </FName>
<Lname>Ratz </Lname>
</Person>
<Person>
<FName>Steven</FName>
<Lname>Styer </Lname>
</Person>
</PeopleInApartment>
</Apartment>
</Apartments>

Use xml linq :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication3
{
class Program
{
const string FILENAME = #"c:\temp\test.xml";
static void Main(string[] args)
{
XDocument doc = XDocument.Load(FILENAME);
XElement apartments = new XElement("Apartments");
var groups = doc.Descendants("Person")
.GroupBy(x => (int)x.Element("ApartmentNumber"))
.ToList();
foreach (var group in groups)
{
XElement peopleInApartment = new XElement("PeopleInApartment", group);
apartments.Add(peopleInApartment);
}
}
}
}

Please check Below :
select
(select t2.FName, t2.Lname, t1.ApartmentNumber
from #TEMP t2
where t2.ApartmentNumber = t1.ApartmentNumber
for xml path('Person'), type
) as PeopleInApartment
from #TEMP t1
group by ApartmentNumber
for xml path(''), root ('Apartments')

I want to get the value of the payloadID on the DocumentReference element. This is what I have tried so far:
BEGIN
Declare #Xml xml
Set #Xml = ('..The XML From Above..' as xml)
END
--no value comes back
Select c.value('(/*/DocumentReference/#payloadID)[0]','nvarchar(max)') from #Xml.nodes('//cXML') x(c)
--no value comes back
Select c.value('#payloadID','nvarchar(max)') from #Xml.nodes('/cXML/*/DocumentReference') x(c)
--check if element exists and it does
Select #Xml.exist('//DocumentReference');
I tried this in an xPath editor: //DocumentReference/#payloadID
This does work, but I am not sure what the equivalent syntax is in SQL

Calling .nodes() (like suggested in comment) is an unecessary overhead...
Better try it like this:
SELECT #XML.value('(//DocumentReference/#payloadID)[1]','nvarchar(max)')
And be aware, that XPath starts counting at 1. Your example with [0] cannot work...
--no value comes back
Select c.value('(/*/DocumentReference/#payloadID)[0]','nvarchar(max)') from...

insert an element to nth element in a xml in Sql Server

please consider this XML:
<Employees>
