Hello. I have in my db some convocations with a state. (false,
true) , I wanna fetch the one-ones which state its true. how to do
this.
I was thinking in doing hte following
1 -EOQualifier qual = Convocation.STATE.eq(true), but thtat retunr
me a boolean.
// Assumes that "state" is a boolean implemented as an integer.
NSArray convocations =
EOUtilities.objectsMatchingKeyAndValue(editingContext,
"Convocation", "state", new Integer(1));
EOUtilities.objectsMatchingKeyAndValue() is a short cut for the
following:
EOQualifier qual = new EOKeyValueQualifier("state",
EOQualifier.QualifierOperatorEqual, new Integer(1));
EOFetchSpecification fetchSpec = new
EOFetchSpecification("Convocation", qual, null);
NSArray convocations =
editingContext.objectsWithFetchSpecification(fetchSpec);
I think Gus mentioned that he is using the ERPrototypes boolean
prototype which maps to a varchar.
And he is using the Wonder Veogen templates so he gets named ERXKeys
for each of his attributes that he can use to easily build qualifiers.
