Hello,
I want to perform a data import from a relational database.
That all works well.
However, i want to dynamically create a unique id for my solr documents
while importing by using my data config file. I cant get it to work, maybe
its not possible this way, but i thought i would ask you ll.
(I set up schema.xml to use the field "id" as the unique id for solr
documents)
My solr config looks like this :
<dataConfig>
<dataSource
name = "wld"
type="JdbcDataSource"
driver="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost/wld"
user="root"
password="pass"/>
<document name="variants">
<entity name="III_1_1" query="SELECT * FROM `wld`.`III_1_1`">
<field column="id" name='${variants.name + "id"}'/>
<field column="lemmatitel" name="lemma" />
<field column="vraagtekst" name="vraagtekst" />
<field column="lexical_variant" name="variant" />
</entity>
<entity name="III_1_2" query="SELECT * FROM `wld`.`III_1_2`">
<field column="id" name='${"III_1_2_" + "id"}'/>
<field column="lemmatitel" name="lemma" />
<field column="vraagtekst" name="vraagtekst" />
<field column="lexical_variant" name="variant" />
</entity>
</document>
</dataConfig>
For a unique id I would like the concatenate the primary key of the table
(Column id) with the table name.
How can I do this ? Both ways as shown in the example data config don't work
while importing.
Any help is appreciated.
Martin
