例外狀況
備註
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. When the length is set to -1, the stream is allowed, but a specific length is not required. If the Reader passes a stream of a different length than what is specified, the JDBC driver will stop the update while it tries to preserve the connection and the current transaction.
