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:
