    SQLException contains some database-specific info related to the exception. From the doc:

    Each SQLException provides several
    kinds of information:

    1) a string
    describing the error. This is used as
    the Java Exception message, available
    via the method getMesage.

    2) a “SQLstate”
    string, which follows either the XOPEN
    SQLstate conventions or the SQL 99
    conventions. The values of the
    SQLState string are described in the
    appropriate spec. The DatabaseMetaData
    method getSQLStateType can be used to
    discover whether the driver returns
    the XOPEN type or the SQL 99 type.

    3) an
    integer error code that is specific to
    each vendor. Normally this will be the
    actual error code returned by the
    underlying database.

    4) a chain to a next
    Exception. This can be used to provide
    additional error information.
