-----------------------------------------
Summary: Incorrect nullability for CASE expression with parameter
Key: DERBY-6567
URL: https://issues.apache.org/jira/browse/DERBY-6567
Project: Derby
Issue Type: Bug
Components: SQL
Affects Versions: 10.10.2.0
Reporter: Knut Anders Hatlen
Assignee: Knut Anders Hatlen
This JUnit test code fails because it detects that the query returns null even
though the result column is reported as not nullable:
{code}
PreparedStatement ps = prepareStatement(
"values case when false then 1 else ? end");
ps.setNull(1, Types.INTEGER);
JDBC.assertSingleValueResultSet(ps.executeQuery(), null);
{code}
