>
> Key: DERBY-1576
> URL: https://issues.apache.org/jira/browse/DERBY-1576
> Project: Derby
> Issue Type: Improvement
> Components: SQL
> Reporter: Christian d'Heureuse
> Priority: Minor
> Labels: derby_triage10_11
>
> The ISO/IEC 9075-2:1999 SQL standard describes two kinds of CASE expressions:
> "simple case" and "searched case".
> The current Derby version supports "searched case" but not "simple case".
> The syntax for "simple case" is:
> CASE Expression
> WHEN Expression THEN Expression
> [ WHEN Expression THEN Expression ]
> ...
> ELSE ElseExpression
> END
> Example:
> VALUES
> CASE 4
> WHEN 1 THEN 'one'
> WHEN 2 THEN 'two'
> WHEN 3 THEN 'three'
> ELSE 'many'
> END
