SqlServer中BULK INSERT用法简介，批量插入数据

news 2025/6/6 20:03:56

首先，我们创建一张TABLE，如下面T-SQL脚本:

   1:  create table test

   2:  (id int,

   3:  amount int check(amount >=1000 and amount<=5000));

假设有这样的文本数据：

1    700

2    2000

3    870

4    4500

下面这个语句不检查约束:

   1:  bulk insert test

   2:  from 'f:\test.txt'

   3:  with

   4:  (fieldterminator=',',

   5:  rowterminator='\n')

这个是启用约束的：

   1:  bulk insert test

   2:  from 'f:\test.txt'

   3:  with

   4:  (fieldterminator=',',

   5:  rowterminator='\n',

   6:  check_constraints)

   7:  select * from test

还可以使用FIRSTROW和LASTROW限制行数。如下COPY前三行：

   1:  bulk insert test

   2:  from 'f:\test.txt'

   3:  with

   4:  (fieldterminator=',',

   5:  rowterminator='\n',

   6:  FIRSTROW =1,

   7:  LASTROW=3)

使用ERRORFILE选项错误处理，如下记录到F:\error.txt

   1:  bulk insert test

   2:  from 'f:\test.txt'

   3:  with

   4:  (fieldterminator=',',

   5:  rowterminator='\',

   6:  FIRSTROW =1,

   7:  LASTROW=3,

   8:  ERRORFILE ='F:\error.txt',

   9:  check_constraints)
