Oracle data import and export commonly used in two ways:
1 through plsql - dmp for import and export file> export / import -> tool;
2. Use command imp / exp performed oracle import and export data.
The first way: using PLSQL export / into the database: Open plsql, find toolbar
Export Table: access the Export page, select the folder, enter the name of the exported file, click Save; Click the Export button to pop export data profiles; can find this in your chosen path dmp files, backup operation is complete
Import Table: Go to import the home page, select the folder, select Import files, and users can click Import

Example:
Data export:
The database TEST 1 full export , user name, password manager system to export to the D: \ daochu.dmp in
exp system/manager@TEST file=d:\daochu.dmp full=y
Table 2 export system user and the user's database sys
exp system/manager@TEST file=d:\daochu.dmp owner=(system,sys)
3 database table table1, table2 Export
exp system/manager@TEST file=d:\daochu.dmp tables=(table1,table2)
4 filed1 the field in the database table table1 export data "00" starts
exp system/manager@TEST file=d:\daochu.dmp tables=(table1) query=\" where filed1 like '00%'\"
Data import:
1 D: \ daochu.dmp the data into the TEST database.
imp system / manager @ TEST file = d: \ daochu.dmp
The above may be a problem, because some tables already exist, then it will error, the table will not be imported. Followed by the ignore = y on it.
2 d: \ daochu.dmp introduced in table table1
imp system/manager@TEST file=d:\daochu.dmp tables=(table1)
