[jira] Updated: (DERBY-2002) Case expression allows NULL in all parts of

     [ http://issues.apache.org/jira/browse/DERBY-2002?page=all ]

Yip Ng updated DERBY-2002:
--------------------------

    Description: 
According to the SQL:2003 spec, section 6.11 <case expression> Syntax Rule 3.  At least one <result> in a 
<case specification> shall specify a <result expression>.  Derby currently is violating this rule.  e.g.:

ij> values case when 1=2 then NULL when 1=3 then NULL else NULL end;
1
----
NULL

1 row selected

6.11 <case expression> Format section defines <result> as the following:

<result> ::= 
    <result expression>
    | NULL

The above statement should have thrown a SQLException instead of returning a result.
