NClob

public interface NClob
implements Clob

java.sql.NClob

The mapping in the Java^TM 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.

From interface


  
    java.sql.Clob

`abstract void`	`free()` This method frees the `Clob` object and releases the resources the resources that it holds.
`abstract InputStream`	`getAsciiStream()` Retrieves the `CLOB` value designated by this `Clob` object as an ascii stream.
`abstract Reader`	`getCharacterStream()` Retrieves the `CLOB` value designated by this `Clob` object as a `java.io.Reader` object (or as a stream of characters).
`abstract Reader`	`getCharacterStream(long pos, long length)` Returns a `Reader` object that contains a partial `Clob` value, starting with the character specified by pos, which is length characters in length.
`abstract String`	`getSubString(long pos, int length)` Retrieves a copy of the specified substring in the `CLOB` value designated by this `Clob` object.
`abstract long`	`length()` Retrieves the number of characters in the `CLOB` value designated by this `Clob` object.
`abstract long`	`position(String searchstr, long start)` Retrieves the character position at which the specified substring `searchstr` appears in the SQL `CLOB` value represented by this `Clob` object.
`abstract long`	`position(Clob searchstr, long start)` Retrieves the character position at which the specified `Clob` object `searchstr` appears in this `Clob` object.
`abstract OutputStream`	`setAsciiStream(long pos)` Retrieves a stream to be used to write Ascii characters to the `CLOB` value that this `Clob` object represents, starting at position `pos`.
`abstract Writer`	`setCharacterStream(long pos)` Retrieves a stream to be used to write a stream of Unicode characters to the `CLOB` value that this `Clob` object represents, at position `pos`.
`abstract int`	`setString(long pos, String str, int offset, int len)` Writes `len` characters of `str`, starting at character `offset`, to the `CLOB` value that this `Clob` represents.
`abstract int`	`setString(long pos, String str)` Writes the given Java `String` to the `CLOB` value that this `Clob` object designates at the position `pos`.
`abstract void`	`truncate(long len)` Truncates the `CLOB` value that this `Clob` designates to have a length of `len` characters.
