[jira] Created: (DERBY-3662) Derby should support the SQL 2003 explict casting behavior

Derby should support the SQL 2003 explict casting behavior
----------------------------------------------------------

                 Key: DERBY-3662
                 URL: https://issues.apache.org/jira/browse/DERBY-3662
             Project: Derby
          Issue Type: Improvement
            Reporter: Rick Hillegas


The "CAST function" section of the Derby Developer's Guide says that Derby supports the casts which were legal in SQL 92. There are a number of casts which are legal in SQL 2003 which Derby does not support. These include the casting of exact numerics to varchar and the casting of inexact numerics to char and varchar. The SQL 2003 rules are defined in part 2 section 6.12 (<cast specification>). Derby should support the liberal 2003 casting behavior. See for instance this user feedback from  Bogdan Calmac: http://www.nabble.com/Concatenating-two-numbers-as-a-string-td17036203.html#a17036203
