SQL 加载程序在某些环境中未加载所有列

Question

我遇到了一个很奇怪的问题，这个问题与 SQL Loader 有关。它加载某些数据库中的所有列，而跳过其他数据库中的最后一列。是的，目标 table 结构在所有数据库中都是相同的。

csv 文件如下所示：

OPTIONS (ERRORS=50, DIRECT=TRUE, SKIP=1)
LOAD DATA
INFILE *
REPLACE
INTO TABLE STAGING.PRODUCTS
FIELDS TERMINATED BY ';'
TRAILING NULLCOLS (
"PRODUCT_ID",
"PRODUCT_NAME",
"CLIENT_TECHNOLOGY")
BEGINDATA

1;Product1;N/A
2;Product2;N/A
....
100;Product100;N/A

这是日志文件，来自 dev01。这就是我所期望的，也就是所有数据都已成功加载：

"PRODUCT_NAME"                       NEXT     *   ;       CHARACTER            
"CLIENT_TECHNOLOGY"                  NEXT     *   ;       CHARACTER            


Table STAGING.PRODUCTS:
  100 Rows successfully loaded.
  0 Rows not loaded due to data errors.
  0 Rows not loaded because all WHEN clauses were failed.
  0 Rows not loaded because all fields were null.

另一方面，假设 dev12 有不同的日志。最后一栏完全跳过了小镇。

Table STAGING.PRODUCTS:
  100 Rows successfully loaded.
  0 Rows not loaded due to data errors.
  0 Rows not loaded because all WHEN clauses were failed.
  0 Rows not loaded because all fields were null.

知道背后的原因是什么吗？目标 table 在所有环境中都是相同的。

create table STAGING.PRODUCTS
(
  product_id               VARCHAR2(64) not null,
  product_name             VARCHAR2(64) not null,
  client_technology        VARCHAR2(64) 
)

提前致谢:-)

你可能有更大的问题在起作用。请注意两个日志文件中的这些行：

Message 3053 not found;  product=RDBMS; facility=UL
Message 3054 not found;  product=RDBMS; facility=UL

他们不应该在那里。根据一点搜索和这个post，一个文件丢失了，也许需要重新安装客户端？ http://www.orafaq.com/forum/t/51572/2

此外，您不需要在控制文件中的列名称周围加上双引号。我想知道双引号是否暗示区分大小写的列名，例如 SQL 中的 when ，也许 dev12 中的列名不匹配？只是猜测。
