public void updateCharacterStream(java.lang.String columnLabel,
                                  java.io.Reader reader,
                                  long length)

Parameters

columnLabel

A String that contains the column label.

reader

A Reader object.

length

The length of the stream.

Exceptions

SQLServerException

Remarks

This updateCharacterStream method is specified by the updateCharacterStream method in the java.sql.ResultSet interface.

This method passes Unicode characters from a Reader object to selected text and binary columns. This includes all text columns and binary, varbinary, varbinary(max), image, and XML columns, but not UDT columns.

If the length of the stream is different than what is specified in the length parameter, the JDBC driver throws an exception when the row is updated or inserted.

If the length of the stream is unknown, the length parameter may be set to -1 to indicate that the driver should accept the stream regardless of its length. With sqljdbc4.jar, we recommend that you use the JDBC 4.0 method updateCharacterStream Method (java.lang.String, java.io.Reader) when the application wants to update the column from a stream whose length is unknown.
