SQL Loader脚本帮助添加SYSDATE，USER

Question

我正在尝试从文件中加载数据，并且想将CREATED_DATE和UPDATED_DATE设置为SYSDATE并将CREATE_BY和UPDATED_BY设置为USER

这是我正在使用的表：

CREATE TABLE CATALOG
(CNO NUMBER,
CTITLE VARCHAR2(25),
CREATED_BY VARCHAR2(10) NOT NULL,
CREATED_DATE DATE NOT NULL,
UPDATED_BY VARCHAR2(10) NOT NULL,
UPDATED_DATE DATE NOT NULL,
CONSTRAINT CATALOG_PK Primary Key (CNO));

这是数据文件：

1,"Title 1"
2,"Title 2"
3,"Title 3"
4,"Title 4"
5,"Title 5"
6,"Title 6"

和我的控制文件：

LOAD DATA
 INFILE "mydata.csv"
 INTO TABLE CATALOG
 FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY '"'    
 (CNO,CTITLE,CREATED_BY "USER", CREATED_DATE "SYSDATE", UPDATED_BY "USER", UPDATED_DATE "SYSDATE")

当我尝试使用SQL Loader加载它时…所有记录均被拒绝：

Record 1: Rejected - Error on table CATALOG, column CREATED_BY.
Column not found before end of logical record (use TRAILING NULLCOLS)
Record 2: Rejected - Error on table CATALOG, column CREATED_BY.
Column not found before end of logical record (use TRAILING NULLCOLS)
.......

有什么想法我做错了吗？提前致谢。

Answer 1

就像Oracle所说的那样：添加TRAILING NULLCOLS到您的控制文件中：

LOAD DATA
 INFILE "mydata.csv"
 INTO TABLE CATALOG
 FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY '"' TRAILING NULLCOLS  
 (CNO,CTITLE,CREATED_BY "USER", CREATED_DATE "SYSDATE", UPDATED_BY "USER", UPDATED_DATE "SYSDATE")

这是必需的，因为只有前两列在输入文件中。其余的纯粹是计算得出的。

如果未指定，则Oracle尝试读取第三，第四等列，但找不到。
