oracle 中 clob 字段的问题

[Bluess]

oracle 8.1.7 server 在 sun solaris 的机器上，客户端在 win2000 上。当查询clob 自断时返回如下错误：

ORA-03120: two-task conversion routine: integer overflow

请问一下，这是怎么回事？在线等。

select * from tablename

ORA-03120 two-task conversion routine: integer overflow
Cause: An integer value in an internal Oracle structure overflowed when being
sent or received over a heterogeneous connection. This can happen when an
invalid buffer length or too great a row count is specified. It usually indicates a bug in the user application.
Action: Check parameters to Oracle calls. If the problem recurs, reduce all
integer parameters, column values not included, to less than 32767.
