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.

Stavros

Hi Stravos,

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

Thanks

Hi List,

Thanks for your help.

The UNION is on the same EOEntity.

I use NSSet.

(If I understood your question!)
