[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-3032) count query used by Query is not compliant JPQL
[
https://jira.jboss.org/jira/browse/JBSEAM-3032?page=com.atlassian.jira.pl...
]
Mathias Walter commented on JBSEAM-3032:
----------------------------------------
According to the JPQL spec:
COUNT ([DISTINCT] identification_variable | state_field_path_expression |
single_valued_association_path_expression)
Therefore:
String fromClause = ejbql.substring(fromLoc, orderLoc).trim();
return "select count(" + fromClause.substring(fromClause.lastIndexOf("
") + 1) + ") " + fromClause;
Please fix the patches. ;)
count query used by Query is not compliant JPQL
-----------------------------------------------
Key: JBSEAM-3032
URL: https://jira.jboss.org/jira/browse/JBSEAM-3032
Project: Seam
Issue Type: Bug
Components: Framework
Affects Versions: 2.0.2.GA, 2.1.0.A1
Reporter: Dan Allen
Assignee: Dan Allen
Fix For: 2.1.0.BETA1
Attachments: JBSEAM-3032-branch20-v1.txt, JBSEAM-3032-trunk-v1.txt
Original Estimate: 1 hour
Remaining Estimate: 1 hour
The count query used by getCountEjbQl() in Query is not compliant JPQL. It should be:
select count(Entity) from Entity entity
instead of
select count(*) from Entity entity
Where "entity" is the class name of the entity (for instance, Person). You can
test this by using TopLink or OpenJPA.
All we need to do is replace the * with the name of the Entity. (We don't even need
to fish for the alias used in the query).
