## 1. Sqluldr2导出文本 ##

Sqluldr2是灵活与强大的Oracle文本导出程序，主要参数如下：

*  user = username/password@tnsname
 *  sql = SQL file name
 *  query = select statement
 *  field = separator string between fields
 *  record = separator string between records
 *  rows = print progress for every given rows (default, 1000000)
 *  file = output file name(default: uldrdata.txt)
 *  log = log file name, prefix with + to append mode
 *  fast = auto tuning the session level parameters(YES)
 *  text = output type (MYSQL, CSV, MYSQLINS, ORACLEINS, FORM, SEARCH).
 *  charset = character set name of the target database.
 *  ncharset= national character set name of the target database.
 *  parfile = read command option from parameter file  
    使用sqluldr2 help=yes可以查看更多参数说明。

e.g.

sqluldr2 data/data@orcl 
            query="select * from sx_table" 
            parfile=d:\exp.par 
            file=d:\sx_table.txt

exp.par 内容如下：

head=yes
    batch=yes
    safe=yes
    rows=3000000
    record=0x0d0x0a

在当前目录下会生成一个名为”sx\_table\_sqlldr.ctl”的控制文件，通过该控制文件可以用SQL\*Loader将数据加载到sx\_table表中。

## 2. Sqlldr导入文本 ##

Sqlldr（SQL\*Loader）是Oralce用来将文本文件装载到数据库中的。

sqlldr userid=test/test@orcl 
           readsize=33554432 
           streamsize=33554432
           date_cache=10000000 
           direct=true 
           skip_index_maintenance=true
           skip_unusable_indexes=true 
           multithreading=true 
           errors=10000000 
           skip=1 
           log="d:\load.log" 
           control="d:\sx_table_sqlldr.ctl"
           data="d:\sx_table.txt"
