/**
 * <P>An exception that provides information on a database access
 * error or other errors.
 *
 * <P>Each {@code SQLException} provides several kinds of information:
 * <UL>
 *   <LI> a string describing the error.  This is used as the Java Exception
 *       message, available via the method {@code getMessage}.
 *   <LI> 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.
 *       The {@code DatabaseMetaData} method {@code getSQLStateType}
 *       can be used to discover whether the driver returns the XOPEN type or
 *       the SQL:2003 type.
 *   <LI> an integer error code that is specific to each vendor.  Normally this will
 *       be the actual error code returned by the underlying database.
 *   <LI> a chain to a next Exception.  This can be used to provide additional
 *       error information.
 *   <LI> the causal relationship, if any for this {@code SQLException}.
 * </UL>
