ORA-00932 数据类型不一致: 应为 -, 但却获得 -

Posted 2023-04-25

好神奇的错误，这是存储过程在定时处理数据时报出来的，然后我把数据的状态置成初始状态让它重新执行一次又不会报这个错。大个每个月能报出一到两次，这是怎么回事呢

参考技术A TIME = '2013-1-21 0:00:00“检查数据库类型是相同的。 转型的to_date（'2012-01 00:00:00'，'YYYY-MM-DD HH24：MI：SS'）追问

你好，你是说：数据库本来要的为time,然后我是用to_date来转的，然后转后出了点问题？

ORA-00932: inconsistent datatypes: expected BLOB, CLOB got CHARSolutionFor reasons having to do with compatibility, the XDB objects cannot be created by the catproc.sql script. The script catproc.sql therefore calls the catmeta.sql script, which contains fake object views for XDB objects.
The real object views are defined in the catmetx.sql script (this script is invoked by catxdbv.sql which is invoked by catqm.sql).Solution #1
Run following scripts while connected as SYS user:> sqlplus /nolog

SQL> connect / as sysdba
SQL> @?/rdbms/admin/catmetx.sql
SQL> @?/rdbms/admin/utlrp.sql

SQL> exit
Afterwards, re-run the export.or:Solution #2
Run the export with the Export DataPump client. E.g.:> expdp system/manager directory=my_dir \
dumpfile=expdp_full.dmp logfile=expdp_full.log full=y 参考技术A EXP-00056]全部数据库导出终止
