环境：LHR和LHR1用户下都有T3表，如下：

如下，排除T3表，会排除LHR和LHR1这2个用户下的T3表：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | [oracle@lhrora11204 ~]$ expdp \'/ AS SYSDBA\' directory=D1 dumpfile=lhr_%U.dmp EXCLUDE=STATISTICS,TABLE:"in('T3')" LOGFILE=expdp_1.log SCHEMAS=LHR1,LHR CLUSTER=N COMPRESSION=ALL parallel=4 FILESIZE=2g REUSE_DUMPFILES=y Export: Release 11.2.0.4.0 - Production on Sat Dec 3 03:10:41 2022 Copyright (c) 1982, 2011, Oracle and/or its affiliates.

如下写法并不能排除T3表：

使用查询，也会排除所有用户下的T3表：

How to Exclude Multiple Schemas and Tables in Export or Import (Doc ID 2087052.1)
APPLIES TO:
Oracle Database - Enterprise Edition - Version 11.2.0.1 and later
Oracle Database Cloud Schema Service - Version N/A and later
Oracle Database Exadata Cloud Machine - Version N/A and later
Oracle Cloud Infrastructure - Database Service - Version N/A and later
Oracle Database Backup Service - Version N/A and later
Information in this document applies to any platform.
NOTE: In the document content below, the user information and data used represents fictitious data. Any similarity to actual persons, living or dead, is purely coincidental and not intended in any manner.
GOAL
Include or Exclude multiple tables from multiple schemas in full Export or Import.
SOLUTION
Following example will show to exclude or include multiple tables or schemas.
It can be used either on the command line or in a parameter file.
- Example to use include on the command line to include all tables for owner AJ or BJ:
1 2 | expdp system/<PASSWORD> full=Y directory=<DIRECTORY_NAME> dumpfile=<DUMP_NAME>.dmp logfile=<LOG_NAME>.log include=table:\"in \(select table_name from dba_tables where owner like \'AJ%\' or owner like \'BJ%\' \)\" |
- Example to use exclude in a par file to exclude table A1_TAB owned by user AJ and B1_TAB owned by user BJ.
Syntax:
1 2 | EXCLUDE=TABLE:"IN (select table_name from dba_tables where (owner,table_name) in (('<user1>','<table1>'), ('<user2>','<table2>')) )" |
Example:
1 2 | EXCLUDE=TABLE:"IN (select TABLE_NAME from DBA_TABLES where (owner,table_name) in (('AJ','A1_TAB'), ('BJ','B1_TAB')) )" |
There is another workaround mentioned in following document by using the QUERY parameter to make sure no rows for these tables are exported (only metadata is exported). Please refer to:
Note 1474932.1 - How to Exclude Duplicate Tables From Some Schemas During a Full DataPump Export

How to Exclude Duplicate Tables From Some Schemas During a Full DataPump Export (Doc ID 1474932.1)
APPLIES TO:
Oracle Cloud Infrastructure - Database Service - Version N/A and later
Oracle Database Exadata Express Cloud Service - Version N/A and later
Oracle Database Cloud Exadata Service - Version N/A and later
Oracle Database Cloud Schema Service - Version N/A and later
Oracle Database Backup Service - Version N/A and later
Information in this document applies to any platform.
SYMPTOMS
You need to do a full database export but the same table is present in several schemas and you want to exclude this table for one schemas only.
CHANGES
NONE
CAUSE
Duplicate table names.
SOLUTION
Unfortunately, you cannot exclude the tables. From Note 277905.1:
\1. Note that all specified tables in the selected schemas are exported, together with their dependent objects.
It is not possible to include or exclude tables owned by a specific schema with a full database export DataPump job, or schema level export DataPump job with multiple schema's.
\2. As a workaround, you can use the query parameter to make sure no rows for these tables are exported (only metadata is exported):
1 2 3 | QUERY=<owner1>.<table_name>:"where 1 <> 1" QUERY=<owner2>.<table_name>:"where 1 <> 1" |

GOAL
With the classic export client you were able to export with one single export session, tables that were owned by different users.
