Oracle的安裝
oracle的下載，安裝
請參考：
https://www.cnblogs.com/hoobey/p/6010804.html
值得一提的是：
安裝完成，首次啓動Developer的時候，需要制定java.exe的路徑。這個路徑需要選擇oracle安裝目錄下的路徑。
我的機器上，該路徑爲：F:\App\Administrator\product\11.2.0\dbhome_1\jdk\bin
另外，若按照如上步驟安裝連續報錯：unable to find a JVM則是因爲安裝的Oracle 11g R2自帶的SQL Develper是32bit的，但給它的JDK環境是64bit的，所以報錯。
只需要從Oracle官網下載Oracle SQL dEVELOPER x64，然後替換掉原安裝目錄（如F:\App\Administrator\product\11.2.0\dbhome_1）下的sqldeveloper文件夾，然後重新啓動SQL Developer即可。
sqluldr2
Sqluldr2是一款可以快速導出oracle數據庫中的數據的小工具。
Oracle在PL/SQL Developer下，導出文件較慢，尤其在面對海量數據下載時，一款能夠提速50%-75%數據下載速度的工具顯得尤爲重要。Sqluldr2是不錯的選擇。

解壓資源
在windows下，只需要在該地址下打開命令行窗口，直接執行對應的文件即可。
具體的數據格式和命令：
Usage: SQLULDR2 keyword=value [,keyword=value,...]
Valid Keywords:
user = username/password@tnsname
sql = SQL file name
query = select statement

file = output file name(default: uldrdata.txt)
log = log file name, prefix with + to append mode
fast = auto tuning the session level parameters(YES)

charset = character set name of the target database.
ncharset= national character set name of the target database.
parfile = read command option from parameter file

exec = the command to execute the SQLs.
prehead = column name prefix for head line.
rowpre = row prefix string for each line.
rowsuf = row sufix string for each line.
colsep = separator string between column name and value.
presql = SQL or scripts to be executed before data unload.
postsql = SQL or scripts to be executed after data unload.
lob = extract lob values to single file (FILE).
lobdir = subdirectory count to store lob files .
split = table name for automatically parallelization.
degree = parallelize data copy degree (2-128).
for field and record, you can use '0x' to specify hex character code,
\r=0x0d \n=0x0a |=0x7c ,=0x2c, \t=0x09, :=0x3a, #=0x23, "=0x22 '=0x27
oracle數據導出工具sqluldr2
基本簡介
下載完sqluldr解壓後，文件夾內容如下：
sqluldr2.exe 用於32位windows平臺；
sqluldr2_linux32_10204.bin 適用於linux32位操作系統；
sqluldr2_linux64_10204.bin 適用於linux64位操作系統；
sqluldr264.exe 用於64位windows平臺。
使用方法
1、首先將sqluldr2.exe複製到執行目錄下，即可開始使用
2、查看help 幫助
sqluldr2 官方下載
3、執行數據導出命令
3.1、常規導出
sqluldr2 test/[email protected]/orcl query=”select * from temp_001” head=yes file=d:\tmp001.csv
說明：head=yes 表示輸出表頭
3.2、使用sql參數
sqluldr2 test/[email protected]/orcl sql=test_sql.sql head=yes file=d:\tmp001.csv
test_sql的內容爲：
select * from temp_001
3.3、使用log參數
當集成sqluldr2在腳本中時，就希望屏蔽上不輸出這些信息，但又希望這些信息能保留，這時可以用“LOG”選項來指定日誌文件名。
sqluldr2 test/[email protected]/orcl sql=test_sql.sql head=yes file=d:\tmp001.csv log=+d:\tmp001.log
3.4、使用 table 參數
當使用 table 參數時，在目錄下會生成對應的ctl控制文件，如下語句會生成temp_001_sqlldr.ctl文件。
sqluldr2 test/[email protected]/orcl query=”select * from temp_001” table=temp_001 head=yes file=d:\tmp001.csv
