Interface SQLOutput

  • 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.

        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.

      • writeObject

        default void writeObject(Object x,
                         SQLType targetSqlType)
                  throws SQLException
        Writes to the stream the data contained in the given object. The object will be converted to the specified targetSqlType before being sent to the stream.

        When the object is null, this method writes an SQL NULL to the stream.

        If the object has a custom mapping (is of a class implementing the interface SQLData), the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, NClob, Struct, java.net.URL, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

        The default implementation will throw SQLFeatureNotSupportedException

        Parameters:
        x - the object containing the input parameter value
        targetSqlType - the SQL type to be sent to the database.
        Throws:
        SQLException - if a database access error occurs or if the Java Object specified by x is an InputStream or Reader object and the value of the scale parameter is less than zero
        SQLFeatureNotSupportedException - if the JDBC driver does not support this data type
