Hi Raymond,

yes, this is what I mean.

set1 = new set for fs1
set2 = new set for fs2

set1 = set1.setbyunioning(set2)

Hi Stravos,

Thanks for example but where "currentResultsSet" come from? from your 1st eofetchspec?
example :
EOFetchSpecification fs1 = new EOFetchSpecification("ENTITY1", specQualifier1,null);
EOFetchSpecification fs2 = new EOFetchSpecification("ENTITY1", specQualifier2,null);

specQualifier1 join with another entity.

specQualifier2 is a simple qualifier.

I want fs1 union fs2.

Thanks

Hi Raymond,

like below…

EOFetchSpecification fsSpecial = new EOFetchSpecification("Designs", specialQualifier, null);
tempArray = ecQuery.objectsWithFetchSpecification(fsSpecial);
NSSet specialSet = new NSSet(tempArray);
if (intersection) resultsSet = currentResultsSet.setByIntersectingSet(specialSet);
else if(subtraction) resultsSet = currentResultsSet.setBySubtractingSet(specialSet);
else if(union) resultsSet = currentResultsSet.setByUnioningSet(specialSet);

I hope it is what you are asking for.

Hi Stravos,

You use NSSet? What syntax do you use in the eofetchspecification?

Thanks

Hi List,

I want to use UNION in two EOFetch but I don't know how to do it.

Thanks for your help.

The UNION is on the same EOEntity.

I use NSSet.

(If I understood your question!)
