Steven Hawkins updated TEIID-5860:
----------------------------------
      Description: 
In this query 

{code}
SELECT originalLicense.Id,originalLicense.Status__c,originalLicense.ReplacementLicenseID__c,originalLicense.LicenseId__c,originalLicense.vlic_Contract_Number__c,replacementLicense.LicenseId__c as replacementLicenseId ,replacementLicense.LicenseId__c as replacementLicenseLicenseId FROM Product_License__c originalLicense LEFT OUTER JOIN /*+ MAKEDEP */ Product_License__c replacementLicense ON originalLicense.ReplacementLicenseID__c = replacementLicense.Id where originalLicense.vlic_Contract_Number__c = :contractNumber
{code}

We have two requests to salesforce, but could generate a single SOQL query.
