Answer 1

Hi you are using a field job_title which is not a unique key neither required, so you should use the id required key and set it as unique key, or you should configure the unique key to be auto-incremented.

however to get things properly follow this: the id field is defined by default, check that it is in your schema.xml and that it is defined as unique key like below :

<fields> <field name="id" type="string" indexed="true" stored="true" required="true"/> <field name="job_title" type="string" indexed="true" stored="true"/> <!-- other fields definition ... --> </fields> <uniqueKey>id</uniqueKey>

and also in your entity query you should index an 'id' which is unique of your db table like this:

<document name="Jobs"> <entity name="Jobs" query="select * from Jobs"> <!-- id here should be stirng, or you can change its type in its definition in the schema.xml --> <field name="id" column="table_id" /> <field name="job_title" column="job_title" /> </entity> </document>

this should resolve this problem :)

Answer 2

you got no required neither unique key. so you may create an autoincrement required id, or create one and add it as an entity field.

Answer 3

如果您已将id定义为架构中的唯一键，则需要在数据导入期间提供该值

<field name="id" column="job_id" />
