Compiler exception when invoking a routine with NUMERIC argument on J2ME
-------------------------------------------------------------------------
Key: DERBY-3697
URL: https://issues.apache.org/jira/browse/DERBY-3697
Project: Derby
Issue Type: Bug
Components: SQL
Affects Versions: 10.4.1.3
Environment: Operating system = Ubuntu 7.10
VM = phoneme_advanced_mr2-b34
Reporter: Rick Hillegas
Attachments: AnsiSignatures.java
Derby raises an error during byte-code generation when asked to invoke a
routine declared to have a NUMERIC argument and to be bound to a method with a
BigDecimal argument. According to the ANSI standard (see DERBY-3652), SQL
NUMERIC is supposed to map to Java BigDecimal. This is the experiment I ran:
1) I built the 10.4 source, including the AnsiSignatures class (I will attach
this).
2) I ran a script which declared a function with a NUMERIC argument bound to a
method in AnsiSignatures which has a BigDecimal argument.
3) When I invoked the function, the byte-code generator raised an exception.
I am not sure what we want to happen here. The BigDecimal class does exist in
Foundation Profile 1.1.2. For small device platforms which support FP 1.1.2, it
seems reasonable that NUMERIC should map to BigDecimal as the ANSI spec
requires. For small device platforms which don't have a BigDecimal class, I
don't know what we should do. In any event, the current behavior seems wrong.
Here's what I see:
