ORACLE Import and Export

Data export:
1 full export of database test, user Name System Password Manager exported to D:\daochu.dmp
Exp System/[email protected] file=d:\daochu.dmp full=y
2 Exporting the system user in the database to the SYS user's table
Exp System/[email protected] file=d:\daochu.dmp owner= (System,sys)
3 Exporting Tables Table1, table2 in the database
Exp System/[email protected] file=d:\daochu.dmp tables= (table1,table2)
4 Export the field filed1 in table table1 in the database with data beginning with "00"
Exp System/[email protected] file=d:\daochu.dmp tables= (table1) query=\ "where filed1 like ' 0% ' \"
The above is a common export, for compression I do not care, with WinZip to the DMP file can be very good compression.
But add compress=y to the upper order.
Import of data
1 Import the data from the D:\DAOCHU.DMP into the test database.
Imp System/[email protected] File=d:\daochu.dmp
There may be a problem, because some tables already exist, and then it is an error, and the table is not imported.
Add Ignore=y to the back.
2 Import the table table1 in D:\daochu.dmp
Imp system/[email protected] file=d:\daochu.dmp tables= (table1)
