I am trying to help out a customer who is only able to provide me the SQL:


FROM [eSmartDataMart].[datamart].[vIncident] i

LEFT OUTER JOIN [eSmartDataMart].[datamart].[vIncidentRelationships] b ON i.BKIncidentNumber = b.BKIncidentNumber AND b.[RelatedItemType]='Problem Investigation'

LEFT OUTER JOIN [eSmartDataMart].[datamart].[vProblemInvestigation] p ON b.[BKRelatedItemID]=p.[BKProblemInvestigationID]
LEFT OUTER JOIN

My SQL is a little rusty- I see that I have three tables: vIncident, vIncidentRelationships and vProblemInvestigation. I am just a little foggy on how to issue the JOIN commands in FOCUS to generate this code- that is, how does a LEFT OUTER JOIN translate to FOCUS?

sh98110,

You can use a strait JOIN:
  
JOIN LEFT_OUTER 
BKIncidentNumber IN vIncident TO {UNIQUE | MULTIPLE} BKIncidentNumber IN vIncidentRelationships
AS B
END 
JOIN LEFT_OUTER 
BKRelatedItemID IN vIncident TO {UNIQUE | MULTIPLE} BKProblemInvestigationID IN BKProblemInvestigationID
AS P
END

And in your TABLE request add the condition on RelatedItemType.


Or you could use a WHERE-based JOIN:
  
JOIN LEFT_OUTER FILE vIncident AT BKIncidentNumber  TAG I
TO {UNIQUE | MULTIPLE}
-* Choose one of the above
FILE vIncidentRelationships AT BKIncidentNumber TAG B
WHERE I.BKIncidentNumber EQ B.BKIncidentNumber;
WHERE B.RelatedItemType EQ 'Problem Investigation';
END

For the second JOIN, you join the new structure to the third file:
  
JOIN LEFT_OUTER FILE vIncident AT B.BKRelatedItemID 
TO {UNIQUE | MULTIPLE}
-* Choose one of the above
FILE vProblemInvestigation AT BKProblemInvestigationID TAG  P
WHERE B.BKRelatedItemID EQ P.BKProblemInvestigationID ;
WHERE B.RelatedItemType EQ 'Problem Investigation';
END
