sqlldr加载文件,ORA-01722: invalid number解决

sqlldr加载文件,ORA-01722: invalid number解决
 
 
dos2unix 文件:将文件转为unix模式(内为文本的)
 
案例:
 
csv文件
 
sqlldr.control文件
 
LOAD DATA
 
INTO TABLE TOTO
 
FIELDS TERMINATED BY','
 
(BALL_No,MAIN_BALL_FREQUENCY,ADDITIONAL_NO_FREQUENCY)
 
sqlldr.data文件
 
    通过ftp传上来的一个csv文件 /s01/sqlldr/toto.csv
 
 
 
sqlldr k24/k24control=sqlldr.control log=toto.log
 
问题:死活导入不进去,查看toto.log
 
          Record 1: Rejected - Error on table K24.TOTO, column ADDITIONAL_NO_FREQUENCY. 
 
          ORA-01722: invalid number
 
          每行都报这个错误
 
分析原因:被sqlldr导入的表,最后一列是数字型,,而我的csv文件中也是数字,报错非可用的数字,那我有理由怀疑在csv文件的每行最后都有一个回车符(windows中文本格式都有这个东西)
 
测试解决:
 
          1、alter table toto modify ADDITIONAL_NO_FREQUENCY varchar2(20);
 
                再次执行sqlldr  发现数据成功导入
 
                这个结论再次验证了确实在全是数字的csv文本的最后,有不属于数字的东西,那就只有回车符了
 
          2、dos2unixtoto.csv(这个命令会把windows中的文本转成linux格式的文本,其实就是把回车符给去掉)
 
          3、将toto中的数据先行清除,然后将最后一列格式改回
 
                alter table toto modify ADDITIONAL_NO_FREQUENCY number;
 
                再次执行sqlldr。
 
                select 表,发现已经导入成功。
 
 
 
改了一下control file
 
LOAD DATA
 
INFILE 'toto.csv'
 
BADFILE 'toto.bad'
 
APPEND
 
INTO TABLE toto
 
TRAILING NULLCOLS
 
(
 
 BALL_NO INTEGER EXTERNAL TERMINATED BY ',',
 
 MAIN_BALL_FREQUENCY INTEGER EXTERNAL TERMINATED BY ',',
 
 ADDITIONAL_NO_FREQUENCY INTEGER EXTERNAL TERMINATED BY whitespace
 
)
