Subject [jira] [Commented] (OLINGO-1095) JPAQueryBuilder.normalizeMembers encounters issue when EmbedId
Date Thu, 23 Mar 2017 19:26:41 GMT

    [ https://issues.apache.org/jira/browse/OLINGO-1095?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15939080#comment-15939080

Michael Bolz commented on OLINGO-1095:

Hi [~evildracula],

I will take a look into.

The problem seems that the normalization necessary for the navigation property (OLINGO-414)
must not be done for the embedded key case.

Sample: http://localhost:8080/SalesOrderProcessing.svc/SalesOrderLineItems(liId=10L,soId=2L)
Correct (not normalised):
SELECT E1 FROM SalesOrderItem E1 WHERE E1.salesOrderItemKey.liId = 10L AND E1.salesOrderItemKey.soId
= 2L

Not correct (normalised):
SELECT DISTINCT E1 FROM SalesOrderItem E1 JOIN E1.salesOrderItemKey R1 WHERE R1.liId = 10L
AND R1.soId = 2L
