Subquery Support (Unsupported expression type 4 / NSFunctionExpressionType)

[chrisballinger]

We are using a subquery in one of our predicates, and it looks like that is not yet supported. Should we figure out an alternative way?

NSPredicate * predicate = [NSPredicate predicateWithFormat:@"(SUBQUERY(%K, $message, $message.isEncrypted == NO).@count != 0)",OTRManagedBuddyRelationships.messages];

It looks like there is some code to support it but there is a missing "else" which causes it to fail. I added the potentially missing else, but it still fails, so for now we will figure out a way to use less complex NSPredicates.

@chrisballinger thanks for your interest in iMAS. I will look into this, but it seems like quite a bit would need to be added to fully support subqueries. Probably best to work around it for now, since it may be a while till I can get to it. Appreciate you finding the bug, let me know if you encounter anymore issues.

+1 for this...anything I can do to help?

I ended up just adding SQLCipher support to YapDatabase and using that instead.

Hi,

I am using encrypted core data. I struck at this subquery here we are using complex subqueries,I am also facing this issue. ECD is not supporting SUBQUERIES. whether it is fixable in the future.
