Hello everyone,
I did a lot of cleanup in the wiki, mainly to remove the links to the
WikiBooks site and removing dead (404s) links.
Now, I want to clean the wiki even further :
1) Most of the pages coming from WikiBooks have
Programming__WebObjects in their title, example :
Hallo,
I need a qualifier, which fetches data from the database where fielda
= empty and fieldb = empty.
I suppose this is very simple but I don't see it. What do I write
into the qualifier?
null won't work, NULL won't work, Bindings Array with new String()
won't work. Database is
new EOAndQualifier(new NSArray(new EOQualifier[] {
new EOKeyValueQualifier(fielda, EOQualifier.QualifierOperatorEqual,
NSKeyValueCoding.NullValue)
new EOKeyValueQualifier(fieldb, EOQualifier.QualifierOperatorEqual,
NSKeyValueCoding.NullValue) }));
