]
Steve Ebersole updated HHH-6944:
--------------------------------
Description:
Currently dialects return a {{SQLExceptionConversion}} which takes on full responsibility
for conversion. I added {{SQLExceptionConversionDelegate}} to support a more
collaborative/chained approach. The idea is that eventually we would have just a single
{{SQLExceptionConversion}} (or maybe it becomes a class instead of interface) that
contains multiple {{SQLExceptionConversionDelegate}} instances to which it would
delegate.
The {{SQLExceptionConversionDelegate}} instances would be determined from:
# a "static" one based on the JDBC 4 defined {{SQLException}} hierarchy
# one for SQLState codes for either X/Open or SQL-2003 codes, depending on
{{java.sql.DatabaseMetaData#getSQLStateType}}
# vendor specific error code or SQLState interpretations via Dialect

Hardy, assigning to you because you said you wanted to look at this stuff. If not, no
worries, assign it back to me..
