備註
This setCharacterStream method is specified by the setCharacterStream method in the java.sql.Clob interface.
Character data in the CLOB is overwritten by the writer starting at the specified position and can over-run the initial length of the CLOB. Specifying a position+1 value will append characters. Specifying a position+2 or greater (or zero or less) value will cause a position error to be thrown.
