1.1.2. JPQL Dataset
JPQL dataset is produced as result of JPQL query execution. The resulted query fields must have aliases provided using the as
operator. You can use report input parameters and parent bands fields in the JPQL query, similar to SQL query.
Below is an example of a JPQL query with a groupId
parameter, obtained from the group
parent band and an external active
parameter:
select u.name as userName, u.login as userLogin
from sec$User u
where u.group.id = ${group.groupId}
and u.active = ${active}
JPQL queries automatically support soft deletion and return only records which are not deleted.
You can also activate query preprocessing by checking the Preprocess query as Groovy template checkbox below the band editor.
By default, JPQL queries use entities mapped to the the main database. If you want to query entities from an additional data store (see Developer’s Manual), set its name in the Data store field.
