Subject [jira] Commented: (DERBY-2769) Implement error handling/parameter checking in Clob.setString
Date Wed, 29 Apr 2009 21:43:30 GMT

Kathey Marsden commented on DERBY-2769:
---------------------------------------

Committed revision 769948.  I will leave this open until we get the release note finalized.
 I don't think we should backport it because of the behavior changes.

> The error handling, or parameter checking, in Clob.subString is not adequate.
> There are four parameters that can be invalid;
>  * pos
>  * str
>  * offset
>  * len
> The first one is already handled properly, the remaining three are not. They typically
result in some low-level exception like a NPE.
> I have not found anything in the JDBC specification nor JavaDoc that dictates the behavior,
except for that SQLException should use states defined in the SQL 2003 specification. A brief
search there resulted in the following possibilities:
>  22003 - numeric value out of range
>  22004 - null value not allowed
>  2200F - zero-length character string
>  22011 - substring error 
>  22023 - invalid parameter value
> Some of these are already defined by Derby, but with unsuitable or very specific error
messages.
