ORA-02064：不支持分布式操作

Question

这很有效，突然间我从主题中得到错误...... 有查询：

MERGE INTO dpr d
USING (select to_date('2011-04-01', 'YYYY-MM-DD') dpr_ts , 2028184944 dpr_qot_id from dual) s
on (s.dpr_ts = d.dpr_ts and s.dpr_qot_id = d.dpr_qot_id)
when not matched then
insert
(DPR_TS,
DPR_OPEN,
DPR_HIGH,
DPR_LOW,
DPR_CLOSE,
DPR_VOLUME,
DPR_QOT_ID)
values
(to_date('2011-04-01', 'YYYY-MM-DD'),
5.30,
5.40,
5.30,
5.40,
1012700,
2028184944);

任何线索？
