----------------------------------
Attachment: QueryExecutionImpl.java.patch
proposed change
> NPE when SELECTing NULL columns from JOINed tables
> --------------------------------------------------
>
> Key: TEIID-1426
> URL: https://issues.jboss.org/browse/TEIID-1426
> Project: Teiid
> Issue Type: Bug
> Components: Salesforce Connector
> Affects Versions: 7.1.1
> Environment: Latest Teiid 7.1.1 on EAP 5.1 with CXF installed
> Reporter: Wanja Pernath
> Assignee: Steven Hawkins
> Attachments: QueryExecutionImpl.java.patch
>
>
> If you select a column of a joined table which is null, you get a NullPointerException:
> This query results in a NPE:
> SELECT sfdc.salesforce.OpportunityContactRole.id, sfdc.salesforce.Contact.Id, sfdc.salesforce.OpportunityContactRole.ContactId,
> sfdc.salesforce.OpportunityContactRole.isPrimary, sfdc.salesforce.OpportunityContactRole.opportunityId,
> sfdc.salesforce.OpportunityContactRole.role, sfdc.salesforce.Contact.AccountId, sfdc.salesforce.Contact.Email,
> sfdc.salesforce.Contact.Fax, sfdc.salesforce.Contact.FirstName, sfdc.salesforce.Contact.LastName,
> sfdc.salesforce.Contact.MailingCity, sfdc.salesforce.Contact.MailingCountry, sfdc.salesforce.Contact.MailingPostalCode,
> sfdc.salesforce.Contact.MailingStreet, sfdc.salesforce.Contact.Name, sfdc.salesforce.Contact.Phone,
> sfdc.salesforce.Contact.Salutation, sfdc.salesforce.Contact.Mobile
> FROM sfdc.salesforce.OpportunityContactRole LEFT OUTER JOIN sfdc.salesforce.Contact ON sfdc.salesforce.OpportunityContactRole.ContactId = sfdc.salesforce.Contact.Id
> WHERE sfdc.salesforce.OpportunityContactRole.opportunityId = '0066000000AcQ7BAAV'
> After checking which element in Contact could be NULL, I found sfdc.salesforce.Contact.Mobile to be so for this particular opportunity. If I remove it, this query executes as expected.
> This issue seems to be related to: TEIID-1409.
