A null is returned if the conversion does not succeed > The current supported internal types are: > LONG > DOUBLE > STRING > TIMESTAMP > Before implementation, determine what are the semantics of explicit casting > to types less general than the internal types. E.g. what if you cast DOUBLE > to TINYINT? Can we just cast internally to LONG and let the output process > cast to TINYINT? > This JIRA includes all work to make casting operate end-to-end in a SQL query > in vectorized mode, including updates to VectorizationContext. -- This message was sent by Atlassian JIRA (v6.1#6144)
