Your XML got a little mangled, but an easy way is to convert to XMLTYPE which opens up many of the XMLDB features. So you'll have something along the lines:
select
extractvalue(my_xml, '/body/field/text()') tag_value,
extractvalue(my_xml, '/body/field/#entityFldType') attr_value
from ( select xmltype(clob) my_xml from your_table )

can anybody tell how to apply intersect of contain in this field with exampl ..I want to check that todays date/time lies in this range or not
i have the following XML. I'm trying to update/append a part of XML at run-time.
but its quite hard.
<XML>

this is the expectation !
<XML>
<FRUIT_SHOP>JARVIZ</FRUIT_SHOP>
<FRUITS>

Guide me how to handle the append in XML at run-time ?
You can make use of INSERTCHILDXML in Oracle.
WITH t ( old_xml, child_xml, node, field_name) AS
( SELECT
'<XML>
<FRUIT_SHOP>JARVIZ</FRUIT_SHOP>
<FRUITS>
<FRUIT>
<FRUIT_NAME>ORANGE</FRUIT_NAME>
<ORANGE_FIELDS>
<FIELD>
<KEY>COLOUR</KEY>
<VALUE>LIGHT_RED</VALUE>
</FIELD>
<FIELD>
<KEY>WEIGHT</KEY>
<VALUE>1KG</VALUE>
</FIELD>
</ORANGE_FIELDS>
</FRUIT>
</FRUITS>
</XML>
' old_xml,
'<FIELD>
<KEY>MADE</KEY>
<VALUE>Florida</VALUE>
</FIELD>' child_xml,
'/XML/FRUITS/FRUIT/ORANGE_FIELDS' node,
'FIELD' field_name
FROM dual)
SELECT
INSERTCHILDXML(XMLTYPE(old_xml),
node,
field_name,
XMLTYPE(child_xml))
FROM t;

SQL Server query xml attribute for an element value

Using FOR XML PATH ('row'), ROOT ('resultset') in my SQL statement.
What am I missing? Thanks.
It's a bit involved in SQL Server - the normal behavior is what you're seeing - the column names will be used as XML element names.
If you really want all XML elements to be named the same, you'll have to use code something like this:
SELECT
'id' AS 'field/#name',
id AS 'field',
'',
'version' AS 'field/#name',
version AS 'field',
'',
'property' AS 'field/#name',
property AS 'field',
'',
... and so on ....
FROM Person.Person
FOR XML PATH('row'),ROOT('resultset')
This is necessary to make sure the column name is used as the name attribute on the <field> element, and the empty string are necessary so that the SQL XML parser doesn't get confused about which name attribute belongs to what element......
You can do this without having to specify the columns as constants and that will allow you to also use select *. It is a bit more complicated than the answer provided by marc_s and it will be quite a lot slower to execute.
select (
select T.X.value('local-name(.)', 'nvarchar(128)') as '#name',
T.X.value('text()[1]', 'nvarchar(max)') as '*'
from C.X.nodes('/X/*') as T(X)
for xml path('field'), type
)
from (
select (
select T.*
for xml path('X'), type
) as X
from dbo.YourTable as T
) as C
for xml path('row'), root('resultset')
SQL Fiddle
The query creates a derived table where each row has a XML that looks something like this:
<X>
<ID>1</ID>
<Col1>1</Col1>
<Col2>2014-08-21</Col2>
</X>
That XML is then shredded using nodes() and local-name(.) to create the shape you want.
Your SELECT statement needs to look something like this
SELECT
'id' AS [field/#name],
id AS field,
'version' AS [field/#name],
version AS field,
'property' AS [field/#name],
property AS field,
'release_date' AS [field/#name],
release_date AS field,
'territory_code' AS [field/#name],
territory_code AS field,
'territory_description' AS [field/#name],
territory_description AS field,
'currency_code' AS [field/#name],
currency_code AS field
I want to extract the value of Decision using sql from table TRAPTABCLOB having column testclob with XML stored as clob. IN DB2

One of the nice things about using XMLTABLE() is that it produces an expression that can be used as a subquery or joined to a table or another SQL expression.
SELECT x.decision
FROM traptabclob, XMLTABLE(
'$d/DCResponse/ContextData[1]' PASSING XMLPARSE(DOCUMENT testclob) AS "d"
COLUMNS
DECISION CHAR(1) PATH 'Field[#key="**Decision**"][1]'
) AS x
;
I need some more help with another XML query. Below is an example of a record of my XML column:
<Fields>
<MappedFields>
<Field name="FormNumber" value="21" />
<Field name="ProcedureCode" value="T2023" />
<Field name="CurrentDate" value="4/23/2012" />
</MappedFields>
</Fields>
The field elements may appear in any order, so it can appear like this as well:
<Fields>
<MappedFields>
<Field name="ProcedureCode" value="G5532" />
<Field name="FormNumber" value="12" />
<Field name="CurrentDate" value="3/29/2011" />
</MappedFields>
</Fields>
What I am looking for, is a query that will get the value of the Field with the name "FormNumber" for all the records in the table. The query I have below works if the Field with the name of "FormNumber" is the first Field element in the XML. What I need is a query that will find the Field element even if it is not the first element. Can someone help me out with this?
SELECT
X.Node.value(N'(Field/#value)[1]', 'nvarchar(max)') AS FormNumber
FROM
dbo.MHTCM_LetterSent A
CROSS APPLY A.LetterXML.nodes(N'/Fields/MappedFields') AS X(Node)
WHERE
X.Node.value(N'(Field/#name)[1]', 'nvarchar(max)') = 'FormNumber'
You can have a test in the xml path like [#name="FormNumber"].
SELECT
X.Node.value(N'(Field[#name="FormNumber"]/#value)[1]', 'nvarchar(max)') AS FormNumber
FROM
dbo.MHTCM_LetterSent A
CROSS APPLY A.LetterXML.nodes(N'//Fields/MappedFields') AS X(Node)
Note the WHERE isn't needed now.
It might make more sense to move the test to the CROSS APPLY:
SELECT
X.Node.value(N'(./#value)[1]', 'nvarchar(max)') AS FormNumber
FROM
dbo.MHTCM_LetterSent A
CROSS APPLY A.LetterXML.nodes(N'//Fields/MappedFields/Field[#name="FormNumber"]') AS X(Node)
Edit- I made the paths absolute (//) and both examples are working for me.
