      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.

    - #### SQLWarning

          public SQLWarning(String reason,
                            String SQLState,
                            int vendorCode)

      Constructs a `SQLWarning` object with a given `reason`, `SQLState` and `vendorCode`. The `cause` is not initialized, and may subsequently be initialized by a call to the `Throwable.initCause(java.lang.Throwable)` method.

      Parameters:
        `reason` - a description of the warning
        `SQLState` - an XOPEN or SQL:2003 code identifying the warning
        `vendorCode` - a database vendor-specific warning code

    - #### SQLWarning

          public SQLWarning(String reason,
                            String SQLState)

      Constructs a `SQLWarning` object with a given `reason` and `SQLState`. The `cause` is not initialized, and may subsequently be initialized by a call to the `Throwable.initCause(java.lang.Throwable)` method. The vendor code is initialized to 0.

      Parameters:
        `reason` - a description of the warning
        `SQLState` - an XOPEN or SQL:2003 code identifying the warning

    - #### SQLWarning

          public SQLWarning(String reason)

      Constructs a `SQLWarning` object with a given `reason`. The `SQLState` is initialized to `null` and the vendor code is initialized to 0. The `cause` is not initialized, and may subsequently be initialized by a call to the `Throwable.initCause(java.lang.Throwable)` method.

      Parameters:
        `reason` - a description of the warning

    - #### SQLWarning

          public SQLWarning()

      Constructs a `SQLWarning` object. The `reason`, `SQLState` are initialized to `null` and the vendor code is initialized to 0. The `cause` is not initialized, and may subsequently be initialized by a call to the `Throwable.initCause(java.lang.Throwable)` method.

    - #### SQLWarning

          public SQLWarning(Throwable cause)

      Constructs a `SQLWarning` object with a given `cause`. The `SQLState` is initialized to `null` and the vendor code is initialized to 0. The `reason` is initialized to `null` if `cause==null` or to `cause.toString()` if `cause!=null`.

      Parameters:
        `cause` - the underlying reason for this `SQLWarning` (which is saved for later retrieval by the `getCause()` method); may be null indicating the cause is non-existent or unknown.

    - #### SQLWarning

          public SQLWarning(String reason,
                            Throwable cause)

      Constructs a `SQLWarning` object with a given `reason` and `cause`. The `SQLState` is initialized to `null` and the vendor code is initialized to 0.

      Parameters:
        `reason` - a description of the warning
        `cause` - the underlying reason for this `SQLWarning` (which is saved for later retrieval by the `getCause()` method); may be null indicating the cause is non-existent or unknown.

    - #### SQLWarning

          public SQLWarning(String reason,
                            String SQLState,
                            Throwable cause)

        `cause` - the underlying reason for this `SQLWarning` (which is saved for later retrieval by the `getCause()` method); may be null indicating the cause is non-existent or unknown.

    - #### SQLWarning

          public SQLWarning(String reason,
                            String SQLState,
