/**
* A SQLExceptionConverter implementation which performs conversion based on the underlying SQLState.
* Interpretation of a SQL error based on SQLState is not nearly as accurate as using the ErrorCode (which is,
* however, vendor-specific).
*
* SQLState codes are defined by both ANSI SQL specs and X/Open. Some of the "classes" are shared, others are
* specific to one or another, yet others are custom vendor classes. Unfortunately I have not been able to
* find a "blessed" list of X/Open codes. These codes are cobbled together between ANSI SQL spec and error
* code tables from few vendors documentation.
