--常规load方式

----load.ctl文件

load data

infile 'c:\1.txt'

into table dept

fields terminated by ','

(deptno,dname,loc)

----数据如下

10,Sales,Virginia

20,Accounting,Virginia

30,Consulting,Virginia

40,Finance,Virginia

----建表

create table dept

(

deptno number(2),

dname varchar2(14),s

loc varchar2(13)

)

sqlldr userid='sys/test as sysdba' control='c:\load.ctl' log='c:\log.log'

--sqlldr收到'exceeds maximum length',因为输入文件的字符串默认是255,超过即报错

alter table dept modify dname varchar2(1000);

----load.ctl文件

load data

infile 'c:\1.txt'

into table dept

fields terminated by ','

(deptno,dname,loc)

----数据如下

10,Sales,Virginia

20,Accounting,Virginia

30,Consulting,Virginia

40,Financeaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,Virginia

sqlldr userid='sys/test as sysdba' control='c:\load.ctl' log='c:\log.log'

报错：'exceeds maximum length'

----修改load.ctl

Load data

infile 'c:\1.txt'

into table dept

fields terminated by ','

(deptno,dname char(1000),loc)

sqlldr userid='sys/test as sysdba' control='c:\load.ctl' log='c:\log.log'

--如何加载定界符

Load data

infile 'c:\1.txt'

into table dept

fields terminated by ',' optionally enclosed by '"'

(deptno,dname char(1000),loc)

----数据如下

10,Sales,"Virginia,USA"

20,Accounting,"Va,""Virginia"""

30,Consulting,Virginia

40,Finance,Virginia

----结果如下

10,Sales,Virginia,USA

20,Accounting,Va,"Virginia"

30,Consulting,Virginia

40,Finance,Virginia

----修改load.ctl

Load data

infile 'c:\1.txt'

into table dept

fields terminated by X'07' optionally enclosed by '"'

(deptno,dname char(1000),loc)

sqlldr userid='sys/test as sysdba' control='c:\load.ctl' log='c:\log.log'

----数据如下,用X'07'做分割符

10Sales"Virginia,USA"

20Accounting"Va,""Virginia"""

30ConsultingVirginia

40FinanceVirginia

----结果如下

10SalesVirginia,USA
