and i need to retrieve the XML node for ID - 140208512T200911101 alone. i cant able to get the information using various methods, still didnt get the correct one.
my desired result should be like this :

Please help on this...
Thanks for your support and it is working fine, for getting the #ID value dynamically from a variable we need to user like this :
DECLARE #DCN Varchar(50)
SET #DCN = '140208512T200911101'
select #XMLValues.query('/DOCUMENTS/DOCUMENT[#ID = sql:variable("#DCN")]')
select #XMLValues.query('/DOCUMENTS/DOCUMENT[#ID = "140208512T200911101"]')
Result
<DOCUMENT ID="140208512T200911101">
<REPEATS>
<REPEAT NAME="EXCEPTIONS">
<ROW>
<FIELD VALUE="09_NYC-3A_2" NAME="PageType" />

I have the next XML file:
<?xml version="1.0" encoding="utf-8"?>
<DynamicEntity Name="ProductsMilk">
<Field Name="Name" Type="nvarchar(256)" AllowNulls="false" />
<Field Name="Description" Type="ntext" AllowNulls="false" />
<Field Name="Price" Type="float" AllowNulls="false" />
</DynamicEntity>
I need to read some value from any option of XML-node, for e.g. I need to read the value of Type option from Field node using T-SQL.
How can I do this using internal OpenXML provider in MSSQL?
The following will extract all the data from your XML:
DECLARE #doc VARCHAR(1000) = '<?xml version="1.0" encoding="utf-8"?>
<DynamicEntity Name="ProductsMilk">
<Field Name="Name" Type="nvarchar(256)" AllowNulls="false" />
<Field Name="Description" Type="ntext" AllowNulls="false" />
<Field Name="Price" Type="float" AllowNulls="false" />
</DynamicEntity>';
DECLARE #iDoc INT;
EXECUTE sp_xml_preparedocument #idoc OUTPUT, #doc;
SELECT *
FROM OPENXML(#iDoc, 'DynamicEntity/Field')
WITH
( DynamicEntityName VARCHAR(100) '../#Name',
FieldName VARCHAR(100) '#Name',
[Type] VARCHAR(100) '#Type',
AllowNulls VARCHAR(100) '#AllowNulls'
);
Basically, you just need to specify a column mapping for your xml attributes.
Here is a solution:
DECLARE #x XML = '<?xml version="1.0" encoding="utf-8"?>
<DynamicEntity Name="ProductsMilk">
<Field Name="Name" Type="nvarchar(256)" AllowNulls="false" />
<Field Name="Description" Type="ntext" AllowNulls="false" />
<Field Name="Price" Type="float" AllowNulls="false" />
</DynamicEntity>'
SELECT t.c.value(N'../#Name', N'nvarchar(100)'),
t.c.value(N'#Name', N'nvarchar(100)'),
t.c.value(N'#Type', N'nvarchar(100)'),
t.c.value(N'#AllowNulls', N'nvarchar(100)')
FROM #x.nodes(N'/DynamicEntity/Field') t(c)

the error I get is
Execute of select: SELECT COUNT(*) FROM CusNeiGroupDS WHERE ('1'='1')
on db: SQLServer threw exception: java.sql.SQLException: Invalid
object name 'CusNeiGroupDS'. - assuming stale connection and retrying
query.
But when I put the table name in the datasource like this,I get output but only from that table which I mention and not from the other tables which are joined with FK.
<DataSource ID="CusNeiGroupDS" serverType="sql" tableName="province">
I was able to achieve this with using includeFrom and foreignKey tags in the datasources. Then create another datasource where i use it to include all the coumns I need from the different tables.Like so
<DataSource ID="neighbourDS_1" serverType="sql" tableName="neighbourhood" inheritsFrom="neighbourDS">
<fields>
<field name="provincename" includeFrom="provinceDS.provincename" />
<field name="capital" includeFrom="provinceDS.capital" />
<field name="code" includeFrom="provinceDS.code" />
<field name="telcode" includeFrom="provinceDS.telcode" />
<field name="countyname" includeFrom="countyDS.countyname" />
<field name="district" includeFrom="districtDS.districtname" />
<field name="city" includeFrom="cityDS.cityname" />
<field name="taxcodecity" includeFrom="cityDS.taxcodecity" />
<field name="fdocode" includeFrom="cityDS.fdocode" />
<field name="zone" includeFrom="zoneDS.zone" />

I want to create index between two tables, stock and auction. Basically I am working on a product site. So I have to create index on both tables. and they are not related at all.
In data-config.xml, that I created to create index, I wrote the following code
<dataConfig>
<dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost/database" user="root" password=""/>
<document name="content">
<entity name="stock" query="select ST_StockID,ST_StockCode,ST_Name,ST_ItemDetail from stock where estatus = 'Active' limit 100">
<field column="ST_StockID" name="stock_ST_StockID" />
<field column="ST_StockCode" name="stock_ST_StockCode" />
<field column="ST_Name" name="stock_ST_Name" />
<field column="ST_ItemDetail" name="stock_ST_ItemDetail" />
<entity name="auction" query="select iauctionid,rad_number,vsku,auction_code from auction limit 100">
<field column="iauctionid" name="auction_iauctionid" />
<field column="rad_number" name="auction_rad_number" />
<field column="vsku" name="auction_vsku" />
<field column="auction_code" name="auction_auction_code" />
</entity>
</entity>
</document>
</dataConfig>
and the schema.xml contains the fields are given below.
<field name="stock_ST_StockID" type="string" indexed="true" stored="true" required="true"/>
<field name="stock_ST_StockCode" type="string" indexed="true" stored="true" required="true"/>
<field name="stock_ST_Name" type="string" indexed="true" stored="true" required="true"/>
<field name="stock_ST_ItemDetail" type="text" indexed="true" stored="true" required="true"/>
<field name="auction_iauctionid" type="string" indexed="true" stored="true" required="true"/>
<field name="auction_rad_number" type="string" indexed="true" stored="true" required="true"/>
<field name="auction_vsku" type="string" indexed="true" stored="true" required="true"/>
<field name="auction_auction_code" type="text" indexed="true" stored="true" required="true"/>
But this way the indexes are being created in wrong way as I put the other table data into the first table in data-config.xml. If I create two entity element like given below then the indexes are not being created.
<dataConfig>
<dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost/lc" user="root" password=""/>
<document name="content">
<entity name="stock" query="select ST_StockID,ST_StockCode,ST_Name,ST_ItemDetail from stock where estatus = 'Active' limit 100">
<field column="ST_StockID" name="stock_ST_StockID" />
<field column="ST_StockCode" name="stock_ST_StockCode" />
<field column="ST_Name" name="stock_ST_Name" />
<field column="ST_ItemDetail" name="stock_ST_ItemDetail" />
</entity>
<entity name="auction" query="select iauctionid,rad_number,vsku,auction_code from auction limit 100">
<field column="iauctionid" name="auction_iauctionid" />
<field column="rad_number" name="auction_rad_number" />
<field column="vsku" name="auction_vsku" />
<field column="auction_code" name="auction_auction_code" />
</entity>
</document>
</dataConfig>
I did not get your answer, can you pls elaborate a little more. I also have the same requirement. I have two tables stock and auction. Basically I am working on a product site. So I have to create index on both tables. and they are not related at all.
Please help
Do you get any errors when indexing the data ??
The following data config is fine as you have two unrelated items.
<dataConfig>
<dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost/lc" user="root" password=""/>
<document name="content">
<entity name="stock" query="select ST_StockID,ST_StockCode,ST_Name,ST_ItemDetail from stock where estatus = 'Active' limit 100">
<field column="ST_StockID" name="stock_ST_StockID" />
<field column="ST_StockCode" name="stock_ST_StockCode" />
<field column="ST_Name" name="stock_ST_Name" />
<field column="ST_ItemDetail" name="stock_ST_ItemDetail" />
</entity>
<entity name="auction" query="select iauctionid,rad_number,vsku,auction_code from auction limit 100">
<field column="iauctionid" name="auction_iauctionid" />
<field column="rad_number" name="auction_rad_number" />
<field column="vsku" name="auction_vsku" />
<field column="auction_code" name="auction_auction_code" />
</entity>
</document>
</dataConfig>
However, there are few things missing ?
Whats the id field for the entity ? As each document should have a unique id, the configuration seems missing above.
Also the id should be unqiue for the entites, else the stock and auction should overwrite each other.
So you may want the id append as stock_ & auction_
You can also add a static field as Stock and auction to your schema and populate them, which would help you the filter out the results when searching and hence improve the performance.
For Assigning the Ids -
You can use the following to create the id value - This should append the Stock_ with the ST_StockID field value.
<field column="id" template="Stock_#${stock.ST_StockID}" />
OR
Use alias in sql e.g. SELECT 'Stock_' || ST_StockID AS ID ..... as use -
<field column="id" name="id" />
I'm developing search engine using Solr and I've been successful in indexing data from one table using DIH (Dataimport Handler). What I need is to get search result from 5 different tables. I couldn't do this without help.
if we assume x table with x rows, there should be x * x documents from each table, which lead to, 5x documents if I have 5 tables as total. In dataconfig.xml, I created 5 seperate entities in single document as shown below. the result from indexed data when I query *:* is only 6 of the entity users and 3 from entity classes which is the number of users total rows which is 9.
Clearly, this way didn't work for me, so how can I achieve this using only single core?
note: I followed DIHQuickStart and DIH tutorial which didn't help me.

you need to look at the structures of your tables then either create queries with joins or creat nested entities like this for example
<dataConfig>
<dataSource driver="org.hsqldb.jdbcDriver" url="jdbc:hsqldb:/temp/example/ex" user="sa" />
<document name="schools">
<entity name="school" query="select * from schools s ">
<field column="school_name" name="school_Name" />
<entity name="school_class" query="select * from schools_classes sc where sc.school_name = '${school.school_name}'">
<field column="class_code" name="class_code" />
<entity name="class" query="select class_name from classes c where c.class_name= '${school_class.class_code}'">
<field column="class_name" name="class_name" />
</entity>
</entity>
</entity>
</document>
</dataConfig>
There is a problem when I use solr1.3 delta-imports to update the index. I have added the "last_modified" column in the table. After I use the "full-import" command to index the database data, the "dataimport.properties" file contains nothing, and when I use the "delta-import" command to update index, the solr list all the data in database not the lasted data. My db-data-config.xml:
deltaQuery="select shop_id from shop where last_modified > '${dataimporter.last_index_time}'">
<?xml version="1.0" encoding="UTF-8" ?>
<dataConfig>
<dataSource driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost:3306/funguide" user="root" password="root"/>
<document name="shopinfo">
<entity name="shop" pk="shop_id"
query="select shop_id,title,description,tel,address,longitude,latitude from shop"
<field column="shop_id" name="id" />
<field column="title" name="title" />
<field column="description" name="description" />
<field column="tel" name="tel" />
<field column="address" name="address" />
<field column="longitude" name="longitude" />
<field column="latitude" name="latitude" />
</entity>
</document>
</dataConfig>
Anyboby know how to solve the problem? Thanks!

I also would recommend upgrading to Solr 1.4 RC as there have been quite a few improvements made to delta-imports with DataImportHandler. Please see DataImportHandler - Using delta-import command - wikipage for specifics.
