SQL++ and QueryBuilder Differences
important
N1QL is Couchbase's implementation of the developing SQL++ standard. As such the terms N1QL and SQL++ are used interchangeably in all Couchbase documentation unless explicitly stated otherwise.
Couchbase Lite's SQL++ for Mobile supports all QueryBuilder features. See Table 1 for the features supported by SQL++ but not by QueryBuilder.
