This article introduces the relevant knowledge of "how to use the parfile of the data pump". Many people will encounter such a dilemma in the operation of actual cases, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1. When exporting some tables separately

Expdp\'/ as sysdba\ 'parfile=table.par

The table.par content is as follows

INCLUDE = TABLE: "IN ('EMP','DEPT')"

Or you can use the tables parameter directly when you do not use include

The table.par content is as follows

Tables=EMP,DEPT

2. When excluding certain tables

Expdp\'/ as sysdba\ 'schemas=usera parfile=exclude.par

The exclude.par content is as follows

Exclude=TABLE: "IN ('tablea','tableb','tablec')"

Or when not using parfile, the possible syntax for some operating systems is like this

Expdp\'/ as sysdba\ 'schemas=usera EXCLUDE=TABLE:\ "IN\ (\' tablea\',\ 'tableb\',\ 'tablec\')\"

3. When excluding tables at the beginning of certain characters

Exclude PM_RAW opening table when impdp

Impdp user/passwd directory=dump parfile=para.par dumpfile=dump.dmp logfile=dump.log

The parfile content is as follows:

Exclude=statistics,TABLE: "LIKE 'PM_RAW%'", TABLE: "LIKE' PM_HOU%'", TABLE: "LIKE 'PM_DAY%'", TABLE: "LIKE' PT_%'"

4. When parfile is used together with query parameter

Use parfile=p.par to avoid escaping characters. The following contents are not written separately by parfile,expdp.

Single table

Tables=taa query= "where tablespace_name='SYSTEM'"

Multiple tables

Tables=taa,tee QUERY=taa: "where tablespace_name='SYSTEM'", tee: "where index_type='LOB'"

Or add parentheses.

Tables= (taa,tee) QUERY= (taa: "where tablespace_name='SYSTEM'", tee: "where index_type='LOB'")
