public class SQLWarning
extends SQLException

An exception that provides information on database access warnings. Warnings are silently chained to the object whose method caused it to be reported.

Warnings may be retrieved from `Connection`, `Statement`, and `ResultSet` objects. Trying to retrieve a warning on a connection after it has been closed will cause an exception to be thrown. Similarly, trying to retrieve a warning on a statement after it has been closed or on a result set after it has been closed will cause an exception to be thrown. Note that closing a statement also closes a result set that it might have produced.

  `Connection.getWarnings()`, `Statement.getWarnings()`, `ResultSet.getWarnings()`, Serialized Form

Constructor Summary
`SQLWarning()` Constructs a default `SQLWarning` object.
`SQLWarning(String reason)` Constructs an `SQLWarning` object with the given value for a reason; SQLstate defaults to `null`, and vendorCode defaults to 0.
`SQLWarning(String reason, String SQLstate)` Constructs an `SQLWarning` object with the given reason and SQLState; the vendorCode defaults to 0.
`SQLWarning(String reason, String SQLstate, int vendorCode)` Constructs a fully-specified `SQLWarning` object initialized with the given values.

Method Summary
`SQLWarning` | `getNextWarning()` Retrieves the warning chained to this `SQLWarning` object.
`void` | `setNextWarning(SQLWarning w)` Adds an `SQLWarning` object to the end of the chain.
