All Known Implementing Classes:

SQLOutputImpl
```
public interface SQLOutput
```
The output stream for writing the attributes of a user-defined type back to the database. This interface, used only for custom mapping, is used by the driver, and its methods are never directly invoked by a programmer.
When an object of a class implementing the interface SQLData is passed as an argument to an SQL statement, the JDBC driver calls the method SQLData.getSQLType to determine the kind of SQL datum being passed to the database. The driver then creates an instance of SQLOutput and passes it to the method SQLData.writeSQL. The method writeSQL in turn calls the appropriate SQLOutput writer methods writeBoolean, writeCharacterStream, and so on) to write data from the SQLData object to the SQLOutput output stream as the representation of an SQL user-defined type.

  - writeObject
```
void writeObject(SQLData x)
                 throws SQLException

    Writes to the stream the data contained in the given SQLData object. When the SQLData object is null, this method writes an SQL NULL to the stream. Otherwise, it calls the SQLData.writeSQL method of the given object, which writes the object's attributes to the stream. The implementation of the method SQLData.writeSQ calls the appropriate SQLOutput writer method(s) for writing each of the object's attributes in order. The attributes must be read from an SQLInput input stream and written to an SQLOutput output stream in the same order in which they were listed in the SQL definition of the user-defined type.
    
    Parameters:
    x - the object representing data of an SQL structured or distinct type
    
    Throws:
