Class SQLStateConverter

java.lang.Object
  org.hibernate.exception.SQLStateConverter

All Implemented Interfaces:: SQLExceptionConverter

public class SQLStateConverter
extends Object
implements SQLExceptionConverter

A SQLExceptionConverter implementation which performs converion 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). Use of a ErrorCode-based converter should be preferred approach for converting/interpreting SQLExceptions.
