Oracle Sql Loader 控制文件的问题
我正在尝试使用 sql 加载器加载一些数据。 这是我的控制/数据文件的顶部：
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
...许多其他数据行。
问题是 sql 加载器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
Column Name Position Len Term Encl Datatype
------------------------------ ---------- ----- ---- ---- ---------------------
ASOF_DATE FIRST * , DATE DD-MON-YY
VALUE NEXT * , CHARACTER
STATE NEXT * , CHARACTER
SERIES_ID NEXT * , CHARACTER
CREATE_DATE NEXT * , DATE DD-MON-YYYY
value used for ROWS parameter changed from 10000 to 198
Record 1: Rejected - Error on table ECONOMIC_INDICATORS, column VALUE.
ORA-01722: invalid number
...如果尝试将字符数据插入数字列，则会出现许多类似的错误。
我尝试过没有数据类型规范，所有其他数字规范，但总是出现同样的问题。 有任何想法吗？
另外，关于为什么要更改 Rows 参数有什么想法吗？
I'm trying to load some data using sql loader. Here is the top of my control/data file:
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
... lots of other data lines.
The problem is that sql loader won't recognize the data types I'm specifying. This is the log file:
Table ECONOMIC_INDICATORS, loaded from every logical record.
Insert option in effect for this table: APPEND
Column Name Position Len Term Encl Datatype
------------------------------ ---------- ----- ---- ---- ---------------------
ASOF_DATE FIRST * , DATE DD-MON-YY
VALUE NEXT * , CHARACTER
STATE NEXT * , CHARACTER
SERIES_ID NEXT * , CHARACTER
CREATE_DATE NEXT * , DATE DD-MON-YYYY
value used for ROWS parameter changed from 10000 to 198
Record 1: Rejected - Error on table ECONOMIC_INDICATORS, column VALUE.
ORA-01722: invalid number
... lots of similiar errors, expected if trying to insert char data into a numeric column.
I've tried no datatype spec, all other numeric specs, and always the same issue. Any ideas?
Also, any ideas on why it's changing the Rows parameter?

从您的示例中，SQL*Loader 将尝试将字符串“AL”计算为数字值，这将导致您给出的错误消息。 示例数据的第三位看起来可能是十进制数，而不是列列表中指定的第二位。
From your example, SQL*Loader will try to evaluate the string "AL" to a number value, which will result in the error message you gave. The sample data has something looking like it could be a decimal number at third position, not second as specified int he column list.
