DECLARE #Suggestions TABLE (
[Description] VARCHAR(800)
)
I have above xml in a XML type varible in my stored procedure
how can i insert each text between description tags
in to the table #Suggestions
Try this:
DECLARE #input XML = '<suggestions>
<suggestion>
<description>plate.</description>
</suggestion>
<suggestion>
<description>snack.</description>
</suggestion>
</suggestions>'
DECLARE #Suggestions TABLE ([Description] VARCHAR(800))
INSERT INTO #Suggestions
SELECT
Sugg.value('(description)[1]', 'varchar(800)')
FROM
#input.nodes('/suggestions/suggestion') AS Tbl(Sugg)
SELECT * FROM #Suggestions
The #input.nodes() expression basically turns each <suggestion> node into a row in the "pseudo" table called Tbl(Sugg). From those "rows" (each basically another XML fragment), you then select out the value you're interested in - here the contents of the <description> XML element inside that XML fragment.
You can use LINQ-to-XML to get all suggestions, then you can insert that data into the table.

Let's say there is the following XML data and I want to add an attribute into salary like currency="INR":
<employee>
<salary amount="6000"/>
</employee>
If this data is stored in a column of type XML, then another attribute is being added easily just by using this code snippet:
UPDATE TABLENAME
SET COLUMNNAME.modify('insert attribute currency{"INR"} into (/employee/salary)[1]')
and if this data is stored in a column of type nvarchar(max), then the following query is not working even after casting the data as xml:
UPDATE TABLENAME
SET CAST(CAST(COLUMNNAME AS VARCHAR(MAX)) AS XML).modify('insert attribute currency{"INR"} into (/employee/salary)[1]')
So, help me to resolve second point as I have a column as nvarchar and I need to insert an attribute into saved xml data.
modify() Method works only with variable/column directly and can only used in the SET clause.
So, to solve this since you are storing your data as NVARCHAR, you have two choices:
Alter your table and add a new column with XML datatype, move the data to it from your column, and then UPDATE the data using modify()
Create/declare a table to store your data as XML and do the UPDATE.
Here is an example for what you provide:
CREATE TABLE T
(
Value NVARCHAR(MAX)
);
INSERT INTO T
SELECT N'<employee>
<salary amount="6000"/>
</employee>';
DECLARE #V XML;
SELECT #V = CAST(Value AS XML)
FROM T;
SET #V.modify('insert attribute currency{"INR"} into (/employee/salary)[1]');
UPDATE T
SET Value = CAST(#V AS NVARCHAR(MAX));
SELECT * FROM T;

I have a table column consist with the XML files. I want to read XML data and display it.
I come up with the following code. But it read only one row in the column
want to display other XML data also
declare #xml xml
select #xml = event_data_XML from #temp
SELECT * FROM (
SELECT
CAST(f.x.query('data(#name)') as varchar(150)) as data_name,
CAST(f.x.query('data(value)') as varchar(150)) as data_value
FROM #xml.nodes('/event') as t(n)
CROSS APPLY t.n.nodes('data') as f(x)) X
PIVOT (MAX(data_value) FOR data_name IN (NTDomainName, DatabaseName, ServerName)) as pvt
Output should be like this(NTDomainName, DatabaseName, ServerName are xml data)
There are a bunch of ways you could do this. I'll show you a way I think you'd find easiest.
To start, here's a table with a little test data:
CREATE TABLE dbo.stuff (
id int identity (1,1) primary key
, event_data_xml xml
, create_date datetime default(getdate())
, is_active bit default(1)
);
INSERT INTO dbo.stuff (event_data_xml)
VALUES ('<event name="thing" package="as">something</event>')
INSERT INTO dbo.stuff (event_data_xml)
VALUES ('<event name="otherthing" package="as">something else</event>')
---All records
SELECT * FROM dbo.[stuff];
Make sense so far? Here's the query I'd use if I wanted to mix XML data and column data:
---Parsed up
SELECT event_data_xml.value('/event[1]', 'nvarchar(max)') AS [parsed element #text]
, event_data_xml.value('/event[1]/#name', 'nvarchar(max)') AS [parsed attribute value]
, create_date --column from table
FROM dbo.stuff
WHERE is_active = 1;
Using the value() function on the XML column passing in an xpath to what I want to display and SQL Server data type for how I want it returned.
Just make sure you're selecting a single value with your xpath expression.
I want to store values from a SELECT statement into a variable which is capable of holding more than one value because my SELECT statement returns multiple values of type INT. This is how my SP looks like so far.
ALTER PROCEDURE "ESG"."SP_ADD"
AS
BEGIN
DECLARE #Id table(identifiers VARCHAR);
INSERT INTO #Id (identifiers) VALUES('axaa1aaa-aaaa-a5aa-aaaa-aa8aaaa9aaaa');
INSERT INTO #Id (identifiers) VALUES('bxbb1bbb-bbbb-b5bb-bbb4-bb8bbbb9bbbf');
DECLARE #tranID INT = (SELECT
DOCUMENT_SET_.DOCUMENT_SET_TRANSACTION_ID
FROM DOCUMENT_SET_TRANSACTION
WHERE DOCUMENT_SET_TRANSACTION.IDENTIFIER IN (SELECT identifiers FROM #Id));
END
Variable #tranID should be a list or an array to hold the ids. Is it possible to do it SQL Server?
You can declare a variable of type table
DECLARE #tblTrans TABLE (
tranID INT
);
INSERT INTO #tblTrans
SELECT DOCUMENT_SET_TRANSACTION.DOCUMENT_SET_TRANSACTION_ID
FROM ESG.DOCUMENT_SET_TRANSACTION
WHERE DOCUMENT_SET_TRANSACTION.IDENTIFIER
IN (SELECT identifiers FROM #envelopeId);
Depending on what you want to do with the values after this, you could declare a cursor to loop through them or select straight from the variable.
You could also look into using a temporary table depending on what scope you need.
Try this, only take the firs row of example. Do u try this?
select DOCUMENT_SET_TRANSACTION.DOCUMENT_SET_TRANSACTION_ID,
(STUFF((SELECT '-' + convert(varchar(max),DOCUMENT_SET_TRANSACTION.DOCUMENT_SET_TRANSACTION_ID)
FROM ESG.DOCUMENT_SET_TRANSACTION
FOR XML PATH ('')), 1, 2, '')) AS example
FROM ESG.DOCUMENT_SET_TRANSACTION
I have a table where a column contains XML data. Now i want to retrieve those xml data with restriction of nodes. Kindly see the following example for more explanation on my scenario,
declare #table table (id int, xmlfield xml) insert into #table select 1,'<Root xmlns="">
<Sample>
<Issue>
<Level>one</Level>
<Descp>First Example</Descp>
</Issue>
<Issue>
<Level>two</Level>
<Descp>Second Example</Descp>
</Issue>
</Sample> </Root>'
select * from #table
Now i need the following result set
Id XMLfield
1 first example
ie, for the selected level,i need the decription for it. More clearly, the node should be restricted for <level>one</level>
(need: What is the description for level one ?)
thanks in advance
Have a look at the xml Data Type Methods
select id,
xmlfield.value('(//Issue[Level = "one"]/Descp/text())[1]', 'varchar(100)') as XMLField
from #table
The XQuery you're looking for is
//Issue[Level = "one"]/Descp/data()
My question is similar to this one: Choose a XML node in SQL Server based on max value of a child element
except that my column is NOT of type XML, it's of type nvarchar(max).
I want to extract the XML node values from a column that looks like this:
<Data>
<el1>1234</el1>
<el2>Something</el2>
</Data>
How can I extract the values '1234' and 'Something' ?
doing a convert and using the col.nodes is not working.
CONVERT(XML, table1.col1).value('(/Data/el1)[1]','int') as 'xcol1',
After that, I would like to do a compare value of el1 (1234) with another column, and update update el1 as is. Right now I'm trying to just rebuild the XML when passing the update:
ie
Update table set col1 ='<Data><el1>'+#col2+'</el1><el2>???</el2>
You've got to tell SQL Server the number of the node you're after, like:
(/Data/el1)[1]
^^^
Full example:
declare #t table (id int, col1 varchar(max))
insert #t values (1, '<Data><el1>1234</el1><el2>Something</el2></Data>')
select CAST(col1 as xml).value('(/Data/el1)[1]', 'int')
from #t
-->
1234
SQL Server provides a modify function to change XML columns. But I think you can only use it on columns with the xml type. Here's an example:
declare #q table (id int, col1 xml)
insert #q values (1, '<Data><el1>1234</el1><el2>Something</el2></Data>')
update #q
set col1.modify('replace value of (/Data/el1/text())[1] with "5678"')
select *
from #q
-->
<Data><el1>5678</el1><el2>Something</el2></Data>
At the end of the day, SQL Server's XML support makes simple things very hard. If you value maintainability, you're better off processing XML on the client side.
