SQLLoader8(加载的数据中有换行符处理方法)

SQLLDR加载的数据中有换行符处理方法
1、创建测试表：

CREATE TABLE MANAGER(
MGRNO NUMBER,
MNAME VARCHAR2(30),
JOB VARCHAR2(30),
REMARK VARCHAR2(1000)
);

2、创建控制文件
我们可以通过控制文件，在数据加载前处理remark列的数据，将用户指定的" "字符替换为chr(10)，即标准换行符，创建控制文件如下：

LOAD DATA
INFILE 'D:	estSqlLoaderldr_case11_1.dat'
TRUNCATE INTO TABLE MANAGER
FILELDS TERMINATED BY ","
(MGRNO,MNAME,JOB,REMARK "REPLACE(:REMARK,'\n',CHR(10))"
)

/*这里需要注意的是，替换时必须指定"\n"而不只是" "，因为" "会被SQLLDR识别成换行符并转换成换行标志，这样可能导致数据加载出错。而""是默认转义符，指定该转义符后SQLLDR
就会将" "识别成普通字符了。*/

3、数据文件
保存为D: estSqlLoaderldr_case11_1.dat

10,SMITH,SALES MANAGER,This is SMITH.
He is a Sales Manager. 
11,ALLEN.W,TECH MANAGER,This is ALLEN.W.
He is a Tech Manager. 
16,BLAKE,HR MANAGER,This is BLAKE.
He is a Hr Manager.

4、执行命令

C:UsersAdministrator>sqlldr scott/tiger@orcl control=D:	estSqlLoaderldrTest.ctl
