oracle spool导出数据和sqlldr导入数据

一.利用spool技术导出数据

1.在pl/sql或者sqlplus中执行

-- Oracle批量导出数据
//设置列分隔符
SQL> set colsep ''
//设置不分页	　
SQL> set pageSize  0
//保存导出的文件路径　
SQL> spool C:\Users\Administrator\Desktop\backup\account.txt
//导出数据的查询语句
SQL> select * from user
//关闭spool
SQL> spool off

2.或者将执行的语句放在文件中 通过 @c:user\a.sql去执行

二.利用sqlldr技术导入数据

1.创建account.ctl文件

LOAD DATA
INFILE 'C:\Users\Administrator\Desktop\backup\account.txt'
TRUNCATE INTO TABLE BOK_KEEPACCOUNTDETAIL
FIELDS TERMINATED BY ''
OPTIONALLY ENCLOSED BY '"'
TRAILING NULLCOLS
(
seqno            ,
pseqno            ,
subject                ,
coreaccount          ,
crdrfg    ,
damount        ,
camount              ,
bookno          ,
redmark               ,
accountid                ,
balance        ,
subjectbalancedir                ,
effectflag          ,
lstmntuser         ,
lstmntdate         "to_date(SUBSTR(:lstmntdate,0,19),'yyyy-mm-dd-hh24.mi.ss')"  ,
deptcode
)

2.cmd中执行以下语句 运行导入的ctl文件地址

sqlldr userid=zcgldb/zcgldb@192.168.30.91:1521/orcl control=C:\Users\Administrator\ACCOUNT.CTL errors=100 direct=y
