/**
 * An exception that provides information on a database access error or other
 * errors.
 *
 * 
 * Each {@code SqlException} provides several kinds of information:
 * 

 *  a string describing the error. This is used as the Java Exception
 * message, available via the method {@link getMessage}.
 * 
 a "SQLstate" string, which follows either the XOPEN SQLstate conventions
 * or the SQL:2003 conventions. The values of the SQLState string are described
 * in the appropriate spec.
 * 
 an integer error code that is specific to each vendor. Normally this
 * will be the actual error code returned by the underlying database.
 * 
 the causal relationship, if any for this {@code SqlException}.
 * 
 the SQL string that was executing when the error occurred. May be {@code null}.
 * 
 the position in the SQL string where the error was detected.
 *
