| Original Export Parameter | Comparable Data Pump Export Parameter |
| BUFFER | A parameter comparable to BUFFER is not needed. |
| COMPRESS | A parameter comparable to COMPRESS is not needed. |
| CONSISTENT | A parameter comparable to CONSISTENT is not needed. Use FLASHBACK_SCN and FLASHBACK_TIME for this functionality. |
| CONSTRAINTS | EXCLUDE=CONSTRAINT |
| DIRECT | A parameter comparable to DIRECT is not needed. Data Pump Export automatically chooses the best method (direct path mode or external tables mode). |
| FEEDBACK | STATUS |
| FILE | DUMPFILE |
| FILESIZE | FILESIZE |
| FLASHBACK_SCN | FLASHBACK_SCN |
| FLASHBACK_TIME | FLASHBACK_TIME |
| FULL | FULL |
| GRANTS | EXCLUDE=GRANT |
| HELP | HELP |
| INDEXES | EXCLUDE=INDEX |
| LOG | LOGFILE |
| OBJECT_CONSISTENT | A parameter comparable to OBJECT_CONSISTENT is not needed. |
| OWNER | SCHEMAS |
| PARFILE | PARFILE |
| QUERY | QUERY |
| RECORDLENGTH | A parameter comparable to RECORDLENGTH is not needed because sizing is done automatically. |
| RESUMABLE | A parameter comparable to RESUMABLE is not needed. This functionality is automatically provided for privileged users. |
| RESUMABLE_NAME | A parameter comparable to RESUMABLE_NAME is not needed. This functionality is automatically provided for privileged users. |
| RESUMABLE_TIMEOUT | A parameter comparable to RESUMABLE_TIMEOUT is not needed. This functionality is automatically provided for privileged users. |
| ROWS=N | CONTENT=METADATA_ONLY |
| ROWS=Y | CONTENT=ALL |
| STATISTICS | A parameter comparable to STATISTICS is not needed. Statistics are always saved for tables. |
| TABLES | TABLES |
| TABLESPACES | TABLESPACES (Same parameter; slightly different behavior) |
| TRANSPORT_TABLESPACE | TRANSPORT_TABLESPACES (Same parameter; slightly different behavior) |
| TRIGGERS | EXCLUDE=TRIGGER |
| TTS_FULL_CHECK | TRANSPORT_FULL_CHECK |
| USERID | A parameter comparable to USERID is not needed. This information is supplied as the username/password when you invoke Export. |
| VOLSIZE | A parameter comparable to VOLSIZE is not needed. |
Examples of Using Data Pump Export
Example 2-1 Performing a Table-Mode Export
expdp hr/hr TABLES=employees,jobs DUMPFILE=dpump_dir1:table.dmp NOLOGFILE=y
Example 2-2 Data-Only Unload of Selected Tables and Rows
這段裡面蠻多技巧，是蠻值得學習的、1.parfile，2.CONTENT，2.EXCLUDE，3.QUERY。
首先在C:\TEMP\建立一PARFILE,named c:\temp\exp.par
參數說明：
1.CONTENT=DATA_ONLY ==>表示只轉出資料，不含DDL SCRIPT
2.EXCLUDE=TABLE:"IN ('COUNTRIES', 'REGIONS')" ==>表示排除'COUNTRIES', 'REGIONS' 這兩個TABLE
3.QUERY=employees:"WHERE department_id !=50 ORDER BY employee_id" ==>表示遇到employees Table時 依where條件轉出資料
-----------------------------------------------------
DIRECTORY=dpump_dir1
DUMPFILE=dataonly.dmp
CONTENT=DATA_ONLY
EXCLUDE=TABLE:"IN ('COUNTRIES', 'REGIONS')"
QUERY=employees:"WHERE department_id !=50 ORDER BY employee_id"
---------------------------------------------------------------
執行指令如下：
> expdp hr/hr PARFILE=c:\temp\exp.par
這裡其實有個陷阱，就是你會發現我沒有下FULL=Y，但怎麼幾乎所有的Table都匯出來，
不過設定但EXCLUDE的TABLE是有排除，且employees TABLE只轉出WHERE條件。
DIRECTORY=dpump_dir1 這個指令到底dpump_dir1是在哪個目錄呢?
請下select * from ALL_DIRECTORIES; 就可以知道
Example 2-3 Estimating Disk Space Needed in a Table-Mode Export
若您需要了解您下的匯出佔用SIZE顯示在畫面上，但不轉出，下面是很棒的例子。
> expdp hr/hr DIRECTORY=dpump_dir1 ESTIMATE_ONLY=y TABLES=employees, departments, locations LOGFILE=estimate.log
Example 2-4 Performing a Schema Mode Export
預設狀態是匯出登入帳號的SCHEMA，無需指定。
> expdp hr/hr DUMPFILE=dpump_dir1:expschema.dmp LOGFILE=dpump_dir1:expschema.log
