can you replace <'${dataimporter.delta.id}'> to ${dataimporter.delta.job_id} and test.
deltaImportQuery : (Only used in delta-import) .There is a namespace ${dih.delta.column-name} which can be used in this query. e.g: select * from tbl where id=${dih.delta.id} Solr1.4
as above line mentioned that we can only use column name in delta namespace.

Im making an index in solr from db in the following way:
<document name="Index">
<entity name="c" query="SELECT * FROM C">
<field column="Name" name="name"/>
</entity>
<entity name="p" query="SELECT * FROM P">
<field column="Name" name="name"/>
</entity>
</document>
Is it possible to have a static field that is set for each row that signify what type is returned to client so that one can make a call to the right database table based on that information from the json result?
That is a field that has no column in the table
<field name="id" value="1"/>
Or is there another way to solve this?
<document name="Index">
<entity name="c" transformer="TemplateTransformer" query="SELECT * FROM C">
<field column="Name" name="name"/>
<field column="id" template="1"/>
</entity>
<entity name="p" transformer="TemplateTransformer" query="SELECT * FROM P">
<field column="Name" name="name"/>
<field column="id" template="1"/>
</entity>
</document>
You can add a column to your SQL query that contains static data like this:
<document name="Index">
<entity name="c" query="SELECT *, 'foo' as NameFromC FROM C">
<field column="NameFromC" name="name"/>
</entity>
<entity name="p" query="SELECT *, 'bar' as NameFromP FROM P">
<field column="NameFromP" name="name"/>
</entity>
</document>
If you try to add a field with only name and template attributes, Solr will throw an error saying Field must have a column attribute.
I have done the following settings for dataimport from about 20 mdb files using ucanaccess:
<?xml version="1.0" encoding="UTF-8" ?>

In every time I liked to import from a different dataSource I had to change dataSource attribute manually for both Pages and Titles entities, then perform dataimport without clean. Now with more than 600 mdb files, it is not an wise option. Is there any way to make looping inside the config? In other words: there is a main entity or mdb files that handles all books titles and categories then every book has its own mdb file named with its id for example 245.mdb for the book of id 245, So I need to change the dataSource for Pages and Titles dynamically.
You cannot create dataSources in a loop, but I believe you can pass dataSource information in a parameter variable. So, perhaps, you can loop over your collection outside of Solr and then trigger DIH with the correct source as a parameter variable.
Just ensure to run DIH in sync mode to avoid different calls stepping on each other (I think the param is syncMode)
I've simple DataImportHandler, that is working on my local system and not on my Server. Both the versions of Solr are same i.e Solr 4.6.0.
I've tried these configurations for DataImportHandler:

Locally I've have approx 2K rows, which is indexed properly, and all the child entity show up.
On server, the fields from the child entities are not showing up i.e source, category and currency. The server has approx 6M rows, its a silly doubt but I hope that memory is not the issue. My server is running on m1.medium EC2 instance, Ubuntu 12.04LTS.
Thanks in Advance :)

If you try to add a field with only name and template attributes, Solr will throw an error saying Field must have a column attribute.
I am in the process of redesigning one of our companies site. My boss wants to play around with the idea of replacing all of our navigation with a search box.. the search box should be able to query any of our tables of unrelated data.
So right now I am trying it with 5 tables.
Products
Manufacturers
Category
Ingredients
Uses
So should be able to lookup a product name, a manufacturer name, a category name, an ingredient name, or a use name
When I retrieve the results. if the user clicked on a manufacturer search result.. It will take them to a manufacturer page that lookups all products for that manufacturer.
When clicks on a product page.. link will take them to that actual product information.
Ingredient will take them to a page that will show all products containing that ingredient.
Anyways here is my data config
<dataConfig>
<dataSource driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost:3306/xxx" user="xxx" password="xxx" />
<document>
<entity name="manufacturer" transformer="TemplateTransformer" pk="manNum"
query="SELECT manNum, manName FROM manufacturer
WHERE active = 1">
<field column="id" name="id" template="MAN-${manNum}" />
<field column="type" template="manufacturer" name="type"/>
<field column="manName" name="text"/>
<field column="manNum" name="manNum"/>
</entity>
<entity name="product" transformer="TemplateTransformer"
query="SELECT products.prodNum, products.prodName as text, m.manName FROM products JOIN man m USING (manNum)
WHERE products.active = 1
AND (hideWeb = 0 or hideWeb IS NULL)">
<field column="id" template="PROD-${products.prodNum}" name="id"/>
<field column="type" template="product" name="type"/>
<field column="text" name="text"/>
<field column="manName" name="manName"/>
</entity>
<entity name="ingredients" transformer="TemplateTransformer" pk="id"
query="SELECT id, text FROM inglist WHERE sort != ''">
<field column="id" name="id" template="ING-${inglist.id}"/>
<field column="type" template="ingredient" name="type"/>
<field column="text" name="text" />
</entity>
<entity name="uses" transformer="TemplateTransformer" pk="id"
query="SELECT id, text FROM useslist">
<field column="id" name="id" template="USE-${id}"/>
<field column="type" template="use" name="type"/>
<field column="text" name="text"/>
</entity>
<entity name="categories" transformer="TemplateTransformer" pk="id"
query="SELECT id, textShow as text FROM categorylist">
<field column="id" name="id" template="CATEGORY-${id}"/>
<field column="type" template="category" name="type"/>
<field column="text" name="text"/>
</entity>
</document>
</dataConfig>
And my schema..
<fields>
<field name="id" type="string" indexed="true" stored="true"/>
<field name="text" indexed="true" stored="true" type="text"/>
<field name="type" type="string" indexed="false" stored="true"/>
<field name="manName" type="text" indexed="false" stored="true"/>
<field name="manNum" type="string" indexed="false" stored="false"/>
</fields>
Now perhaps I am not doing this the right way... and there may be a better way to handle this.
Anyways the problem I am running into right now is that I am getting the error missing required field "id". Now products query and manufacturer query does not have an id column in the select.. but I thought the transform query should take care of it? If I do the select prodNum as id .. then all the ids are overwritting each other.
Now I could probably concat it in the actual query.. and will do so as a last resort, but would like to know what I am doing wrong with this solution.
EDIT
Nevermind, it was just a noob issue, for some reason I was thinking that the template variable was refering to the table name in the SQL not the entity name,
So I replaced all of the
With
And it worked.
Prefixing the table-specific ID with a distinct character or string is a good idea. I do it in the SQL, which allows me to check the behavior outside of Solr.
select
concat('b',cast(b.id as char)) as id,
...
It Was a noob issue,
for some reason I was thinking that the template variable was refering to the table name in the SQL not the entity name.
I do it like this:
<entity name="GG-Boryslaw-1939-Phonebook"
transformer="TemplateTransformer,DateFormatTransformer"
pk="id"
query="SELECT * FROM boryslaw_1939_phonebook">
<field column="record_id" template="GG-Boryslaw-1939-Phonebook-${GG-Boryslaw-1939-Phonebook.id}" />
<field column="record_type" template="phonebook" />
<field column="record_source" template="Boryslaw Phonebook (1939)" />
<field column="record_date" template="${GG-Boryslaw-1939-Phonebook.Year}" dateTimeFormat="yyyy" />
...etc...
</entity>
