Matt McCline updated HIVE-15338:
--------------------------------
Description:
Vectorization in vectorized DATEDIFF accidentally treated the scalar parameter
is type DATE (e.g. CURRENT_DATE) as 0.
Current Q file test vectorized_date_funcs.q DOES NOT test the DATE/TIMESTAMP
scalar type case.
And, non-vectorized cases of DATEDIFF are using UTF and returning the wrong
results.
was:
Vectorization in vectorized DATEDIFF when parameter is (date '12-01-16',
column). Jason noted that ('12-01-16', column) treats the first parameter as a
string and is a different case.
Current Q file test vectorized_date_funcs.q DOES NOT test the date scalar type
case.
And, non-vectorized cases of DATEDIFF are using UTF and returning the wrong
results.
> Wrong result from non-vectorized DATEDIFF with scalar parameter of type
