Interface NClob

  • All Superinterfaces:
    Clob

    public interface NClob
extends Clob
    The mapping in the JavaTM programming language for the SQL NCLOB type. An SQL NCLOB is a built-in type that stores a Character Large Object using the National Character Set as a column value in a row of a database table.

    The NClob interface extends the Clob interface which provides provides methods for getting the length of an SQL NCLOB value, for materializing a NCLOB value on the client, and for searching for a substring or NCLOB object within a NCLOB value. A NClob object, just like a Clob object, is valid for the duration of the transaction in which it was created. Methods in the interfaces ResultSet, CallableStatement, and PreparedStatement, such as getNClob and setNClob allow a programmer to access an SQL NCLOB value. In addition, this interface has methods for updating a NCLOB value.

    All methods on the NClob interface must be fully implemented if the JDBC driver supports the data type.
