Method Detail

setString

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

Writes the given Java String to the CLOB value that this Clob object designates at the position pos.

Parameters:

pos - the position at which to start writing to the CLOB value that this Clob object represents

str - the string to be written to the CLOB value that this Clob designates

Returns:

the number of characters written

Throws:

SQLException - if there is an error accessing the CLOB value

Since:

1.4

setString

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

Writes len characters of str, starting at character offset, to the CLOB value that this Clob represents.

Parameters:

pos - the position at which to start writing to this CLOB object

str - the string to be written to the CLOB value that this Clob object represents

offset - the offset into str to start reading the characters to be written

len - the number of characters to be written

Returns:

the number of characters written

Throws:

SQLException - if there is an error accessing the CLOB value

Since:

1.4

setAsciiStream

public OutputStream setAsciiStream(long pos)
                            throws SQLException

Retrieves a stream to be used to write Ascii characters to the CLOB value that this Clob object represents, starting at position pos.

Parameters:

pos - the position at which to start writing to this CLOB object

Returns:

the stream to which ASCII encoded characters can be written

Throws:

SQLException - if there is an error accessing the CLOB value

Since:

1.4

setCharacterStream

public Writer setCharacterStream(long pos)
                          throws SQLException

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.

Parameters:

pos - the position at which to start writing to the CLOB value

Returns:

a stream to which Unicode encoded characters can be written

Throws:

SQLException - if there is an error accessing the CLOB value

Since:
