Subject [jira] [Assigned] (PHOENIX-4292) SOQL Filters on Tables and Views with composite PK of VARCHAR fields with sort direction DESC do not work

>             Project: Phoenix
>          Issue Type: Bug
>    Affects Versions: 4.10.0
>            Reporter: Jan Fernando

> We noticed that in certain instances on tables and views that were defined with a Composite
PK and where the elements of the PK were all DESC that queries exhibited strange behavior
and did not return results when expected. A simple query on the first element of the PK returned
0 results e.g SELECT * FROM MY_TABLE WHERE PK1 = 'myvaluethatexists' would return 0 results.
> After some investigation it appears that querying tables and views with a Composite PK
that :
> a) have multiple VARCHAR columns in the PK
> b) the sort direction of all the VARCHAR columns is defined as DESC 
>  does not work correctly and the filters are not honored and SQL appears broken to the
end user.
> Detailed repro steps:
> ---------------------------
> -- 1. Create Global Base Table

>     CREATED_BY CHAR(15),
>     SYSTEM_MODSTAMP DATE
>     CONSTRAINT PK PRIMARY KEY (
>         TENANT_ID, 
>         KEY_PREFIX 
>     )
> ) VERSIONS=1, MULTI_TENANT=true, IMMUTABLE_ROWS=TRUE, REPLICATION_SCOPE=1
