  Throws:
    `SQLException`

### generateProxy

    public static Clob generateProxy(String string)

  Generates a `Clob` proxy using the string data.

  Parameters:
    `string` - The data to be wrapped as a `Clob`.
  Returns:
    The generated proxy.

### generateProxy

    public static Clob generateProxy(Reader reader,
                                     long length)

  Generates a `Clob` proxy using a character reader of given length.

  Parameters:
    `reader` - The character reader
    `length` - The length of the character reader
  Returns:
    The generated proxy.

### getProxyClassLoader
