Method Detail

length

public long length()
            throws SQLException

Returns the length.

Specified by:

length in interface Clob

Returns:

the length

Throws:

SQLException

truncate

public void truncate(long len)
              throws SQLException

[Not supported] Truncates the object.

Specified by:

truncate in interface Clob

Throws:

SQLException

getAsciiStream

public InputStream getAsciiStream()
                           throws SQLException

Returns the input stream.

Specified by:

getAsciiStream in interface Clob

Returns:

the input stream

Throws:

SQLException

setAsciiStream

public OutputStream setAsciiStream(long pos)
                            throws SQLException

[Not supported] Returns an output stream.

Specified by:

setAsciiStream in interface Clob

Throws:

SQLException

getCharacterStream

public Reader getCharacterStream()
                          throws SQLException

Returns the reader.

Specified by:

getCharacterStream in interface Clob

Returns:

the reader

Throws:

SQLException

setCharacterStream

public Writer setCharacterStream(long pos)
                          throws SQLException

Get a writer to update the Clob. This is only supported for new, empty Clob objects that were created with Connection.createClob() or createNClob(). The Clob is created in a separate thread, and the object is only updated when Writer.close() is called. The position must be 1, meaning the whole Clob data is set.

Specified by:

setCharacterStream in interface Clob

Parameters:

pos - where to start writing (the first character is at position 1)

Returns:

a writer

Throws:

SQLException

getSubString

public String getSubString(long pos,
                  int length)
                    throws SQLException

Returns a substring.

Specified by:

getSubString in interface Clob

Parameters:

pos - the position (the first character is at position 1)

length - the number of characters

Returns:

the string

Throws:

SQLException

setString

public int setString(long pos,
            String str)
              throws SQLException

Fills the Clob. This is only supported for new, empty Clob objects that were created with Connection.createClob() or createNClob(). The position must be 1, meaning the whole Clob data is set.

Specified by:

setString in interface Clob

Parameters:

pos - where to start writing (the first character is at position 1)

str - the string to add

Returns:

the length of the added text

Throws:

SQLException

setString

public int setString(long pos,
            String str,
            int offset,
            int len)
              throws SQLException

[Not supported] Sets a substring.

Specified by:

setString in interface Clob

Throws:

SQLException

position

public long position(String pattern,
            long start)
              throws SQLException

[Not supported] Searches a pattern and return the position.

Specified by:

position in interface Clob

Throws:

SQLException

position

public long position(Clob clobPattern,
            long start)
              throws SQLException

[Not supported] Searches a pattern and return the position.

Specified by:

position in interface Clob

Throws:

SQLException

free
