Oracle Sql加载程序控制文件存在问题

LOAD DATA
INFILE *
APPEND INTO TABLE economic_indicators
FIELDS TERMINATED BY ','
(ASOF_DATE DATE 'DD-MON-YY',
VALUE FLOAT EXTERNAL,
STATE,
SERIES_ID INTEGER EXTERNAL,
CREATE_DATE DATE 'DD-MON-YYYY')
BEGINDATA
01-Jan-79,AL,67.39940538,1,23-Jun-2009

... 很多其他的数据线。

问题是sql loader无法识别我指定的数据类型。这是日志文件:

Table ECONOMIC_INDICATORS, loaded from every logical record.
Insert option in effect for this table: APPEND

value used for ROWS parameter changed from 10000 to 198
Record 1: Rejected - Error on table ECONOMIC_INDICATORS, column VALUE.

... 如果尝试将字符数据插入数字列,则会出现许多类似错误。

我没有尝试过数据类型规范,所有其他数字规范,而且总是相同的问题。有什么想法吗?

还有,你知道为什么要修改Rows参数吗?
