我有那个表-2个数据库中的DIM_BP，具有相同的结构和数据。
这些表在某些列上具有PK。
有一条带有dml错误记录的插入语句，用于捕获插入期间的错误。
当我使用dblink从DB1运行插入命令到DB2时-我收到PK唯一约束错误并且该语句失败（dml错误日志记录被忽略）。
但是当我从DB1到DB1（本地）运行时-没有错误..并且错误表中填充了错误..
示例：
-- truncate table error table
truncate table DWH.ERR$_DWH_CONV;
table DWH.ERR$_DWH_CONV truncated.
-- truncate table in local DB
truncate table DWH.DIM_BP;
table DWH.DIM_BP truncated.
-- (log in to the remote server and) truncate the table
truncate table DWH.DIM_BP;
table DWH.DIM_BP truncated.
-- log to the local DB again
-- first insert into the remote
-- finisehd OK and commited
INSERT /*+ monitor */ INTO DWH.DIM_BP@DWH_DEV
SELECT * FROM ...
LOG ERRORS INTO DWH.ERR$_DWH_CONV ('DWH.DIM_BP@DWH_DEV.2019-04-16 16:05:58') REJECT LIMIT UNLIMITED;
130,091 rows inserted.
commit;
-- first insert into the local
-- finisehd OK and commited
INSERT /*+ monitor */ INTO DWH.DIM_BP
SELECT * FROM ...
LOG ERRORS INTO DWH.ERR$_DWH_CONV ('DWH.DIM_BP@DWH_DEV.2019-04-16 16:05:58') REJECT LIMIT UNLIMITED;
130,091 rows inserted.
commit;
-- run the same insert again into the local table(130091)
INSERT /*+ monitor */ INTO DWH.DIM_BP
SELECT * FROM ...
LOG ERRORS INTO DWH.ERR$_DWH_CONV ('DWH.DIM_BP@DWH_DEV.2019-04-16 16:05:58') REJECT LIMIT UNLIMITED;
0 rows inserted.
COMMIT;
select count(*) from dwh.ERR$_DWH_CONV;
result: 130091
-- run the same insert again into the REMOTE table(130091)
-- RAISED AN ERROR
INSERT /*+ monitor */ INTO DWH.DIM_BP@DWH_DEV
SELECT * FROM ...
LOG ERRORS INTO DWH.ERR$_DWH_CONV ('DWH.DIM_BP@DWH_DEV.2019-04-16 16:05:58') REJECT LIMIT UNLIMITED;
SQL Error: ORA-00001: unique constraint - DWH.DIM_BP_PK
-- check again the error table
select count(*) from dwh.ERR$_DWH_CONV;
result: 130091 (no change)
this is the constraint:
CONSTRAINT "DIM_BP_PK" PRIMARY KEY... ENABLED;
