Victoria Markman created DRILL-1912:
---------------------------------------

             Summary: Throw unsupported error message for window functions 
                 Key: DRILL-1912
                 URL: https://issues.apache.org/jira/browse/DRILL-1912
             Project: Apache Drill
          Issue Type: Bug
          Components: SQL Parser
    Affects Versions: 0.8.0
            Reporter: Victoria Markman


Window functions  below  are currently:

* Supported in Calcite
* Not supported in DRILL
* Not documented in DRILL documentation

ROW_NUMBER()
FIRST_VALUE()
LAST_VALUE()
PERCENT_RANK()
DENSE_RANK()

Spoke to Jacques:  Window function implementation is not targeted until after 1.0 \
release. Therefore, for 0.8.0 release we are going to throw "Unsupported" error \
message for these functions as  well as for every other function that supports OVER \
clause due to two critical bugs below:

DRILL-1487 - window functions return wrong result
DRILL-1902 - new implementation of window functions

Assigning to Jacques on his request, targeting 0.8.0
