public class SQLException
extends Exception

The SQLException class provides information on a database access error.

Each SQLException provides several kinds of information:

a string describing the error. This is used as the Java Exception message, and is available via the getMesage() method
A "SQLstate" string which follows the XOPEN SQLstate conventions. The values of the SQLState string as described in the XOPEN SQL spec.
An integer error code that is vendor specific. Normally this will be the actual error code returned by the underlying database.
A chain to a next Exception. This can be used to provided additional error information.

SQLException(): Construct an SQLException; reason defaults to null, SQLState defaults to null and vendorCode defaults to 0.
SQLException(String): Construct an SQLException with a reason; SQLState defaults to null and vendorCode defaults to 0.
SQLException(String, String): Construct an SQLException with a reason and SQLState; vendorCode defaults to 0.
SQLException(String, String, int): Construct a fully-specified SQLException

getErrorCode(): Get the vendor specific exception code
getNextException(): Get the exception chained to this one.
getSQLState(): Get the SQLState
setNextException(SQLException): Add an SQLException to the end of the chain.
