我正在使用以下脚本来创建备份文件，但它备份了所有表格。我想要备份选定的表格。如何实现这一目标。
以下脚本运行正常。
select 'C:\Daily-MIS-Backup\'||TO_CHAR(SYSDATE,'YYYYMMDD-HH24MISS')||'.DMP' foo3 from dual;
HOST EXP USERID=myusername/mypassFILE='^LOG1' GRANTS=Y ROWS=Y OWNER=SMPSYS LOG=EXPORT.LOG
我们尝试了以下代码，但它备份了所有表格。我们需要备份选定的表格。
select 'C:\Daily-MIS-Backup\'||TO_CHAR(SYSDATE,'YYYYMMDD-HH24MISS')||'.DMP' foo3 from dual;
HOST EXP USERID=myusername/mypassFILE='^LOG1' GRANTS=Y ROWS=Y OWNER=SMPSYS LOG=EXPORT.LOG

Below script is working fine.
select 'C:\Daily-MIS-Backup\'||TO_CHAR(SYSDATE,'YYYYMMDD-HH24MISS')||'.DMP' foo3 from dual;
HOST EXP USERID=myusername/mypassFILE='^LOG1' GRANTS=Y ROWS=Y OWNER=SMPSYS LOG=EXPORT.LOG
We tried following code but it took backup of all tables. we need backup of selected tables.
select 'C:\Daily-MIS-Backup\'||TO_CHAR(SYSDATE,'YYYYMMDD-HH24MISS')||'.DMP' foo3 from dual;
HOST EXP USERID=myusername/mypassFILE='^LOG1' GRANTS=Y ROWS=Y OWNER=SMPSYS LOG=EXPORT.LOG

import 和 export 工具有一个 TABLES 参数。语法如下：
TABLES=(myschema1.table1, myschema2.table2, ...)
如果你在 UNIX 或需要转义括号的操作系统上使用，请记得转义括号。
英文:
The import and export utilities have a TABLES parameter. Syntax is like this:
TABLES=(myschema1.table1, myschema2.table2, ...)
Remember to escape the parentheses if you're on UNIX or an OS that requires that.
