I. Data export:

 

1. Export the database TEST completely, and the username system Password manager is exported to D: \ daochu. dmp.

Exp system/manager @ TEST file = d: \ daochu. dmp full = y

 

2. Export the tables of system users and sys users in the database(Including tables, stored procedures, views, etc)

Exp system/manager @ TEST file = d: \ daochu. dmp owner = (system, sys)

 

3. Export tables table1 and table2 in the database

Exp system/manager @ TEST file = d: \ daochu. dmp tables = (table1, table2)

 

4. Export the data with the field filed1 in table 1 in the database starting with "00"

Exp system/manager @ TEST file = d: \ daochu. dmp tables = (table1) query = \ "where filed1 like '201312 '\"

 

The above is a commonly used export. I am not very concerned about compression. I can use winzip to compress the dmp file.

However, add compress = y to the command above.

  

Ii. Data Import

 

1. import data from D: \ daochu. dmp to the TEST database.

Imp system/manager @ TEST file = d: \ daochu. dmp

The above may be a problem, because some tables already exist, and then it will report an error, the table will not be imported.

Add ignore = y to the end.

 

2. Import table 1 in d: \ daochu. dmp

Imp system/manager @ TEST file = d: \ daochu. dmp tables = (table1)

The preceding import and export operations are sufficient. In many cases, I completely delete the table and then import it.

  

Note:

If you have sufficient permissions, the system will prompt you.

The database can be connected, and the tnsping TEST can be used to determine whether the database TEST can be connected.
