SELECT only specific value from XML column in SQL - sql

Running the following TSQL
SELECT Name FROM Category
returns these results as the column in SQL is of xml data type.
1 <locale en-US="Abstract" />
2 <locale en-US="African" />
3 <locale en-US="Americana" />
I'd like to get a result set like:
1 Abstract
2 African
3 Americana
How can I do this?


You can try to use the .value function
SELECT Name.value('(/locale/#en-US)[1]','varchar(20)')
from Category

WHERE JSON_Value Dynamically

I am working with the JSON_VALUE function and I need a kind of dynamic query
I have a column called Criteria and sometimes it has 1 value but sometimes it has 2 or 3 vales like:
Example of 1 value: $.IRId = 1
Example of 2 values: $.IROwner = 'james.jonson#domain.com' AND DaysTillDue < 10
So in order to read the values from a JSON column and taking the Criteria column I am using this logic:
DECLARE #CriteriaValue int
,#CriteriaStatement VARCHAR(50)
SELECT #CriteriaValue=SUBSTRING(Criteria, CHARINDEX('=',Criteria)+1, len(Criteria)) FROM #SubscriptionCriteria;
SELECT #CriteriaStatement= SUBSTRING(Criteria,0, CHARINDEX('=',Criteria)) FROM #SubscriptionCriteria;
SELECT #CriteriaValue,#CriteriaStatement
SELECT *
FROM [SAAS].[ObjectEvent]
WHERE
JSON_VALUE(JSONMessageData, #CriteriaStatement) = #CriteriaValue
That SQL code is taking only the Criteria Column with only 1 value ($.IRId = 1), but the idea is to have something that reads the criteria no matter the different filters and apply them into the final query. The idea I have is that the query would look like this:
SELECT *
FROM [SAAS].[ObjectEvent]
WHERE
JSON_VALUE(JSONMessageData, #CriteriaStatement1) = #CriteriaValue1 ADN JSON_VALUE(JSONMessageData, #CriteriaStatement2) = #CriteriaValue2 AND
JSON_VALUE(JSONMessageData, #CriteriaStatement3) = #CriteriaValue3
ETC
Any suggestion?

How to UPDATE value for fields inside a xml column : SQL Server 2012

I have a sql table let's say Criteria, having a xml column ResultCriteria.
Criteria
CriteriaID CriteriaName ResultCriteria
1 Criteria1 <Results>.... </Results>
Value for ResultCriteriaColumn :
<Results>
<Result Name=Result1 Title=SearchResultTile1 SortOrder=Asc>
<Result Name=Result2 Title=SearchResultTile2>
<Result Name=Result3 Title=SearchResultTile3 Parent=XYZ>
</Results>
And a configuration table where Titles for Result columns are stored like:-
ResultColumnNameID ResultColumnName Title
1 Result1 TitleA
2 Result2 TitleB
Now i have to update(Change name from a config table) ResultCriteria for every row through a sql script.
I have managed to fetch data in two table variable like
ResultLookup
ResultColumnName Title
Result1 Title1
Result2 Ttile3
TempTableToUpdate (i created this for first row, so that i can repeat this logic on every row by using cursor.)
CriteriaRow1 ResultXML
Criteria1 <Name='Result1' Title='Result1Title' Parent='ABC'/>
Criteria1 <Name='Result2' Title='Result2Title' Sort='ASC'/>
Criteria1 <Name='Result3' Title='Result3Title' Parent='XYZ'/>
PS: ResultColumnName is unique
Now i just have to replace Title from ResultLookup(Table 1) to ResultXML, convert everything back to Xml. Finally update this new xml into row 1 of Criteria table.
Could someone please suggest how this can be achieved in SQL Server 2012 ?

XML Data into Row Selection

I have a single field in a DB which contains columns of data, but in an continuous string of XML.
I want to extract the data from the XML, and return as normal columns.
There could be multiple rows of data within this single field.
Here are 2 real examples of data in this field
Example 1:
<DocumentElement>
<AuditTrailDetail>
<TableName>order_header_total</TableName>
<RowID>837</RowID>
<AuditType>Edit</AuditType>
<FieldName>oht_foreign_net</FieldName>
<ValueFrom>65.1600</ValueFrom>
<ValueTo>115.1600</ValueTo>
<EntityName />
<DisplayName />
<Identifier />
</AuditTrailDetail>
<AuditTrailDetail>
<TableName>order_line_item</TableName>
<RowID>2442</RowID>
<AuditType>Edit</AuditType>
<FieldName>oli_qty_required</FieldName>
<ValueFrom>1.0000</ValueFrom>
<ValueTo>2.0000</ValueTo>
<EntityName />
<DisplayName />
<Identifier>61 - test</Identifier>
</AuditTrailDetail>
</DocumentElement>
Example 2:
<DocumentElement>
<AuditTrailDetail>
<TableName>order_line_item</TableName>
<RowID>2446</RowID>
<AuditType>Edit</AuditType>
<FieldName>oli_description</FieldName>
<ValueFrom>2 Ply Tissue Masks</ValueFrom>
<ValueTo>2 Ply Tissue Masksdd</ValueTo>
<EntityName />
<DisplayName />
<Identifier>D/D170 - 2 Ply Tissue Masksdd</Identifier>
</AuditTrailDetail>
</DocumentElement>
For Example 1, I'd like to return 2 rows as below:
For Example 2 there is one row, and I'd like it as below:
The fields in the table are:
owat_id
owat_audit_type
owat_record_id
owat_record_type
owat_datetime
owat_ud_id
owat_details
The XML data is within owat_details.
Assume the table name is Audit_Trail.
How can I do this directly in the SQL query?

Thank you to Johnie Karr
I have got this working using XQuery.
I have to do 2 queries and union them together to get the 2 separate elements in one field as separate rows. I'm sure there is a cleaner solution, but this works.
Thank you very much :)

xmlquery returns all values as one long line instead of separate entities

I am trying to query the telephone numbers from the following xml file
<xmlPhoneEntity>
<TelephoneEntity>
<number>123</number>
</TelephoneEntity>
<TelephoneEntity>
<number>456</number>
</TelephoneEntity>
<TelephoneEntity>
<number>789</number>
</TelephoneEntity>
</xmlPhoneEntity>
This XML is located in my DB - the table looks like this
id customer_id telephone blabla
1 111 xmlfile
2 222 xmlfile
etc
My sql query looks like this -
select xmlserialize(xmlquery('/xmlPhoneEntity/TelephoneEntity/number/text()
passing telephone"
the response: 123456789
I tried using /nodes() instead of /text() and the result is the same.
How do I separate the values ?
