I have the follow XML
<root>
<business name="LM" id="1" total_pes="0">
</business>
<business name="KO" id="354" total_pes="0">
</business>
<business name="TUI" id="889" total_pes="0">
</business>
</root>
I want to update the total_pes attribute with a record count of other table tbl_logs:
id | log
1 | A
1 | A
1 | A
354 | A
354 | A
889 | A
My output XML would be this:
<root>
<business name="LM" id="1" total_pes="3">
</business>
<business name="KO" id="354" total_pes="2">
</business>
<business name="TUI" id="889" total_pes="1">
</business>
</root>
This is what I already done:
DECLARE #total_pes_new int
DECLARE #ID INT
SET #ID = (SELECT TOP 1 ID FROM #IDS)
WHILE #ID IS NOT NULL
BEGIN
set #total_pes_new = ( SELECT COUNT(A.PES) FROM TBL A
WHERE A.ID = #ID)
SET #XML.modify('replace value of (/root/business[#id=sql:variable("#ID")]/#total_pes)[1] with sql:variable("#total_pes_new")')
SET #ID = (SELECT TOP 1 ID FROM #IDS WHERE ID > #ID)
END
I will have problems with this loop. Can anyone help me to do a better solution?
Tks
If your XML is in an XML database, then you also have the option of using XQuery Update, see http://www.w3.org/TR/xquery-update-10/.

I am running below query on SQL Server 2014 server but I can't understand why I am getting only one row in result.
DECLARE #idoc int, #doc varchar(1000);
SET #doc ='

);
How do I get all 3 records returned like below
You should use the built-in, native XQuery support (instead of the legacy OPENXML stuff...).
Use this code to get all the details down to the <OrderDetail> node (define your #doc variable as XML):
DECLARE #doc XML;
SET #doc = '......';
SELECT
OrderID = XOD.value('#OrderID', 'int'),
CustomerID = XCus.value('#CustomerID', 'varchar(20)'),
ContactName = XCus.value('#ContactName', 'varchar(50)'),
EmployeeID = XOrder.value('#EmployeeID', 'int'),
OrderDate = XOrder.value('#OrderDate', 'datetime'),
ProductID = XOD.value('#ProductID', 'int'),
Quantity = XOD.value('#Quantity', 'int'),
ReturnOrderID = RetD.value('#ReturnOrderID', 'int'),
ReturnDate = RetD.value('#ReturnDate', 'datetime')
FROM
#doc.nodes('/ROOT/Customer') AS XT(XCus)
CROSS APPLY
XCus.nodes('Order') AS XT2(XOrder)
CROSS APPLY
XOrder.nodes('OrderDetail') AS XT3(XOD)
OUTER APPLY
XOD.nodes('ReturnDetail') AS XT4(RetD)
For each "level" that might contain multiple nodes (like <Customer> under <ROOT> etc.), you need to use CROSS APPLY and the .nodes() XQuery function to get all the child nodes - not just one (first or arbitrary).
I want to create a sitemap xml file (including images) directly from the database without another process (like transformation or another trick).
My query is:
;WITH XMLNAMESPACES(
DEFAULT 'http://www.sitemaps.org/schemas/sitemap/0.9',
'http://www.google.com/schemas/sitemap-image/1.1' as [image] )
SELECT
(SELECT
'mysite' as [loc],
(select
'anotherloc'
as [image:loc]
for XML path('image:image'), type
)
for xml path('url'), type
)
for xml path('urlset'), type
Returns:
<urlset xmlns:image="http://www.google.com/schemas/sitemap-image/1.1" xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<url xmlns:image="http://www.google.com/schemas/sitemap-image/1.1" xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<loc>mysite</loc>
<image:image xmlns:image="http://www.google.com/schemas/sitemap-image/1.1" xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<image:loc>anotherloc</image:loc>
</image:image>
</url>
</urlset>
But I need this output, without repeated namespace declaration:
<urlset xmlns:image="http://www.google.com/schemas/sitemap-image/1.1" xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<url>
<loc>mysite</loc>
<image:image>
<image:loc>anotherloc</image:loc>
</image:image>
</url>
</urlset>
I'm sure you realise that the additional otiose namespace declarations don't change the meaning of the XML document, so if the result is going to be consumed by an XML-conformant tool, they shouldn't matter. Nevertheless I know there are some tools out there which don't do XML Namespaces correctly, and in a large XML instance superfluous repeated namespace declarations can bloat the size of the result significantly, which may cause its own problems.
In general there is no getting around the fact that each SELECT...FOR XML statement within the scope of a WITH XMLNAMESPACES prefix will generate namespace declarations on the outermost XML element(s) in its result set, in all XML-supporting versions of SQL Server up to SQL Server 2012.
In your specific example, you can get fairly close to the desired XML by separating the SELECTs rather than nesting them, and using the ROOT syntax for the enveloping root element, thus:
DECLARE #inner XML;
WITH XMLNAMESPACES('http://www.google.com/schemas/sitemap-image/1.1' as [image])
SELECT #inner =
(
SELECT
'anotherloc' AS [image:loc]
FOR XML PATH('image:image'), TYPE
)
;WITH XMLNAMESPACES(
DEFAULT 'http://www.sitemaps.org/schemas/sitemap/0.9'
)
SELECT
'mysite' AS [loc],
#inner
FOR XML PATH('url'), ROOT('urlset'), TYPE
The result being:
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<url>
<loc>mysite</loc>
<image:image xmlns:image="http://www.google.com/schemas/sitemap-image/1.1" xmlns="">
<image:loc>anotherloc</image:loc>
</image:image>
</url>
</urlset>
But this approach doesn't provide a completely general solution to the problem.
You can use UDF. Example:
ALTER FUNCTION [dbo].[udf_get_child_section] (
#serviceHeaderId INT
)
RETURNS XML
BEGIN
DECLARE #result XML;
SELECT #result =
(
SELECT 1 AS 'ChildElement'
FOR XML PATH('Child')
)
RETURN #result
END
GO
DECLARE #Ids TABLE
(
ID int
)
INSERT INTO #Ids
SELECT 1 AS ID
UNION ALL
SELECT 2 AS ID
;WITH XMLNAMESPACES (DEFAULT 'http://www...com/content')
SELECT
[dbo].[udf_get_child_section](ID)
FROM
#Ids
FOR XML PATH('Parent')
Result:
<Parent xmlns="http://www...com/content">
<Child xmlns="">
<ChildElement>1</ChildElement>
</Child>
</Parent>
<Parent xmlns="http://www...com/content">
<Child xmlns="">
<ChildElement>1</ChildElement>
</Child>
</Parent>
Maybe too late for answer, but this is a quick solution.

I am using mybatis to retrieve data from DB, the data returned is containing duplicate entries.
Required result : Column Name , Value
Expected result is : column1 value A
But returned result is : COLUMN1 value A , column1 value A.
Hope able to clarify my doubt.
Can anybody tell me why it is happening?
<select id="getContentMap" resultType="map" parameterType="map">
select planId,location_qualifier from disclaimer_disclosure_content where
<choose>
<when test="plan_id != null">
plan_id = #{plan_id}
</when>
<when test="product_id != null">
product_id = #{product_id}
</when>
<otherwise>
issuer_id = #{issuer_id}
</otherwise>
</choose>
and effective_date >= #{effective_date}
and location_qualifier LIKE CONCAT('%' , #{location_qualifier} , '%')
</select>
The issue you are seeing is a bug in MyBatis 3 up until release 3.0.6: http://code.google.com/p/mybatis/issues/detail?id=303.
After that release you get the answer I outlined in my other answer (which was done with MyBatis 3.1.1).
You have four options:
Just ignore it and only grab the uppercase or lowercase entries
Upgrade to at least 3.0.6
Stop using map as resultType and move to a POJO domain object
Use the workaround below:
workaround for MyBatis < 3.0.6
Use full uppercase column aliases and they will only show up once (as uppercase) in your map:
<select id="getContentMap" resultType="map" parameterType="map">
select plan_id as PLAN_ID, location_qualifier as LOCATION_QUALIFIER from disclaimer_disclosure_content
where
<!-- SNIP: is the same as you had -->
</select>
This results in the output:
{PLAN_ID=2, LOCATION_QUALIFIER=Bar}
(or something similar depending on exactly how your select looks).
You will probably need to report more information, such as:
what database are you using?
what version of MyBatis 3 are you using (or are you still using iBATIS)?
what does your table structure look like?
In any case, I tried out a slightly simplified version of your query using MySQL 5.1 and MyBatis-3.1.1 and it worked fine - meaning that I only got back one entry of the column name in the result map. I provide my setup below so you can try to reproduce it or diagnose where your code may be wrong.
First, you have a error in your select statement. You have
SELECT planId
but then you have:
WHERE ... plan_id = #{plan_id}
so you probably meant SELECT plan_id in the SELECT clause.
Here is what worked for me.
My slightly simplified MyBatis select mapping is:
<select id="getContentMap" resultType="map" parameterType="map">
SELECT plan_id, location_qualifier FROM disclaimer_disclosure_content
WHERE
<choose>
<when test="plan_id != null">
plan_id = #{plan_id}
</when>
<otherwise>
product_id = #{product_id}
</otherwise>
</choose>
AND location_qualifier LIKE CONCAT('%' , #{location_qualifier} , '%')
</select>
Second, my MySQL table for this query:
mysql> select * from disclaimer_disclosure_content;
+---------+--------------------+------------+
| plan_id | location_qualifier | product_id |
+---------+--------------------+------------+
| 1 | Foo | 101 |
| 2 | Bar | 102 |
| 3 | Baz | 103 |
| 4 | Quux | 104 |
+---------+--------------------+------------+
4 rows in set (0.01 sec)
Third, my Java code to use the mapping:
#Test
public void testForSO() throws Exception {
Map<String, Object> paramMap = new HashMap<String, Object>();
paramMap.put("plan_id", 2);
paramMap.put("location_qualifier", "Ba");
List<Map<String,Object>> lmap = session.selectList("getContentMap", paramMap);
assertNotNull(lmap);
Map<String,Object> m = lmap.get(0);
assertNotNull(m);
System.out.println(m.toString());
}
This passes and prints out:
{location_qualifier=Bar, plan_id=2}
I also tried it with
Map<String,Object> m = session.selectOne("getContentMap", paramMap);
and get the same expected result.
how would you write a t-sql query if the namespace is prefixed in all of the elements? I've tried many variations, and this is what I've got so far, but it just doesn't work...

I have a table like this:
ID Name Column1 Column2 Column3
1 ABC 202.2 1500 34000
2 IJK 104 10000 27000
I want to generate XML like this:
<doc>
<record ID="1" Name="ABC" Column1="202.2" Column2="15000" Column3="34000" />
<record ID="2" Name="IJK" Column1="104" Column2="10000" Column3="27000" />
</doc>
I have got some clue from this forum post and used this code:
CREATE TABLE #tmp (column1 VARCHAR(20), column2 VARCHAR(20), column3 VARCHAR(20))
INSERT INTO #tmp VALUES ( 'data1', 'data2', 'data3' )
INSERT INTO #tmp VALUES ( 'data11', 'data21', 'data31' )
-- FOR XML PATH with ELEMENTS will automatically unpivot the data for you
-- Then reshape your XML using nested FLWOR loops
SELECT
(
SELECT *
FROM #tmp t
FOR XML PATH, ELEMENTS, TYPE
).query('
for $e in row
return
<row>{
for $f in $e/*
return <field name="{local-name($f)}">{data($f)}</field>
}
</row>
')
I tried the following modified version:
SELECT (SELECT * FROM cte_temp t FOR XML PATH, ELEMENTS, TYPE)
.query('for $e in row return
<doc>
{
for $f in $e return <record {local-name($f)}="{data($f)}" />
}
</doc>')
But I'm getting error:
XQuery [query()]: Invalid source character 0x7b found in an identifier
near 'return'.
Why you trying to get fancy.
Select * from #tmp as record
FOR XML AUTO, root('doc')
