使用 sql 加载器加载到 table 时跳过前两条记录

Question

我有一个 CSV 文件，包含 4181 条记录和从 excel 中的第 5 行开始的记录。

Table :

CREATE TABLE SQL_LOAD
(col1 number(10),
Col2  varchar2(4000),
Col3  varchar2(4000),
Col4  varchar2(4000),
Col5  varchar2(4000),
Col6  varchar2(4000),
Col7  varchar2(4000),
Col8  varchar2(4000),
Col9  varchar2(4000),
Col10  varchar2(4000),
Col11  varchar2(4000),
Col12  varchar2(4000),
Col13  varchar2(4000),
Col14  varchar2(4000),
Col15  varchar2(4000),
Col16  varchar2(4000),
Col17  varchar2(4000),
Col18  varchar2(4000),
Col19  varchar2(4000),
Col20  varchar2(4000),
Col21  varchar2(4000),
Col22  varchar2(4000),
Col23  varchar2(4000),
Col24  varchar2(4000),
Col25  varchar2(4000),
Col26  varchar2(4000),
Col27  varchar2(4000),
Col28  varchar2(4000),
Col29  varchar2(4000),
Col30  varchar2(4000),
Col31  varchar2(4000),
Col32  varchar2(4000),
Col33  varchar2(4000),
Col34  varchar2(4000),
Col35  varchar2(4000),
Col36  varchar2(4000),
Col37  varchar2(4000),
Col38  varchar2(4000),
Col39  varchar2(4000),
Col40  varchar2(4000),
Col41  varchar2(4000),
Col42  varchar2(4000),
Col43  varchar2(4000),
Col44  varchar2(4000),
Col45  varchar2(4000),
Col46  varchar2(4000),
Col47  varchar2(4000),
Col48  varchar2(4000),
Col49  varchar2(4000),
Col50  varchar2(4000),
Col51  varchar2(4000),
Col52  varchar2(4000),
Col53  varchar2(4000),
Col54  varchar2(4000),
Col55  varchar2(4000),
Col56  varchar2(4000),
Col57  varchar2(4000),
Col58  varchar2(4000),
Col59  varchar2(4000),
Col60  varchar2(4000),
Col61  varchar2(4000),
Col62  varchar2(4000),
Col63  varchar2(4000),
Col64  varchar2(4000),
Col65  varchar2(4000),
Col66  varchar2(4000),
Col67  varchar2(4000),
Col68  varchar2(4000),
Col69  varchar2(4000),
Col70  varchar2(4000),
Col71  varchar2(4000),
Col72  varchar2(4000),
Col73  varchar2(4000),
Col74  varchar2(4000),
Col75  varchar2(4000),
Col76  varchar2(4000)
constraint pk_sql_load primary key (col1)
);

控制文件：

    options (
    skip = 4,
    DIRECT = TRUE
    )
    load data
    infile 'I:\SQLLOADER\sqlloader.csv'
    append
    continueif last != ','
    into sql_load
    fields terminated by ","
    optionally enclosed by '"'
    trailing nullcols
    (
    Col1,
Col2,
Col3,
Col4,
Col5,
Col6,
Col7,
Col8,
Col9,
Col10,
Col11,
Col12,
Col13,
Col14,
Col15,
Col16,
Col17,
Col18 CHAR(4000),
Col19,
Col20,
Col21,
Col22,
Col23,
Col24,
Col25,
Col26,
Col27,
Col28,
Col29,
Col30,
Col31,
Col32,
Col33,
Col34,
Col35,
Col36,
Col37,
Col38,

Col40,
Col41,
Col42,
Col43,
Col44,
Col45,
Col46,
Col47,
Col48,
Col49,
Col50,
Col51,
Col52,
Col53,
Col54,
Col55,
Col56,
Col57,
Col58,
Col59,
Col60,
Col61,
Col62,
Col63,
Col64,
Col65,
Col66,
Col67,
Col68,
Col69,
Col70,
Col71,
Col72,
Col73,
Col74,
Col75,
Col76
    )

我可以看到插入了 4179 条记录，但不只插入第 5 行和第 6 行的前两条记录 excel，并且从第 7 行开始它插入了所有记录。有人可以帮我解决为什么它只跳过前两条记录吗？

感谢您提供测试用例。

首先，table：

SQL> CREATE TABLE SQL_LOAD
  2  (col1 number(10),
  3  Col2  varchar2(4000),
  4  Col3  varchar2(4000),
<snip>
 77  Col76  varchar2(4000),                       --> comma was missing here
 78  constraint pk_sql_load primary key (col1)
 79  );

Table created.

SQL>

我下载了示例数据（只是为了说明文件包含的内容，这里是屏幕截图）：

控制文件，稍作修改（后运行行，删除continueif）：

options (
    skip = 4,
    DIRECT = TRUE
    )
load data
infile 'c:\temp\sqlloader.csv'
replace into table sql_load
fields terminated by ","
optionally enclosed by '"'
trailing nullcols
(
Col1,
Col2,
Col3,
<snip>
Col75,
Col76
)

加载会话：

SQL> select count(*) From sql_load;

  COUNT(*)
----------
         0

SQL> $sqlldr scott/tiger control=test7.ctl log=test7.log

Load completed - logical record count 10.

SQL>

已加载 10 行；这正是我们所期望的，因为必须跳过前 4 行，而从 1 到 10 的 COL1 值代表我们需要的行。

那么，table内容是什么？

SQL> select count(*) From sql_load;

  COUNT(*)
----------
        10

SQL> select col1, col2, col3 from sql_load;

      COL1 COL2                                     COL3
---------- ---------------------------------------- ----------
         1 LINE LEVEL IRE CAN DV01 -DD-MMM-YYYY     High

         7 SC45667                                  High
         8 410_qqret                                High
         9 Sv and PA_OEE                            High
        10 FAU                                      High

10 rows selected.

显然，一点问题都没有，一切都已成功加载。

因此，要么你没有post 代表性样本数据，要么你遇到了我无法重现的问题。我运行我的 Oracle 11gXE 数据库中的那个例子。
