Updates the designated column with a character stream value.
The updater methods are used to update column values in the
current row or the insert row.  The updater methods do not
update the underlying database; instead the <code>updateRow</code> or
<code>insertRow</code> methods are called to update the database.

<P><B>Note:</B> Consult your JDBC driver documentation to determine if
it might be more efficient to use a version of
<code>updateCharacterStream</code> which takes a length parameter.

@param columnIndex the first column is 1, the second is 2, ...
@param x the new column value
@exception SQLException if a database access error occurs,
the result set concurrency is <code>CONCUR_READ_ONLY</code>
or this method is called on a closed result set
@exception SQLFeatureNotSupportedException if the JDBC driver does not support
this method
