[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.
