建立物化视图的语句是什么？
显示刷新成功，在哪里显示的？使用 dbms_mview.refresh 手动刷新的？

是的，手动dbms刷新的，显示执行成功，奇怪的是物化视图日志也不记录数据的变化，count(*)一直是0条数据

SQL> select count(*) from jymasb.MLOG$_T_API_INVENTORY_LOG;

COUNT(*)

     0

Create Materialized View Log On T_API_INVENTORY_LOG With Rowid;

SQL> exec dbms_mview.refresh(‘T_DT_INVENTORY_LOG_MV’,‘f’);

PL/SQL procedure successfully completed.

日志没建错库？？ 看你用了dblink

没建错啊，不然其他库都没这个表。
