SQL Server大数据量插入

SQL Server大数据插入方法比较多，下面我们先谈谈Bulk insert 方法。

首先，我们创建一张TABLE，如下面T-SQL脚本:

 create table TestTable2

  (id int,

  amount int check(amount >=1000 and amount<=5000))

假设有这样的文本数据 testdata.txt：

1    700      

2    2000      

3    870      

4    4500      

下面这个语句不检查约束:

1:  bulk insert TestTable2      

2:  from 'D:\testdata\testdata.txt'      

3:  with      

4:  (fieldterminator=',',      

5:  rowterminator='\n')      

这个是启用约束的：

1:  bulk insert TestTable2      

2:  from 'D:\testdata\testdata.txt'      

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 TestTable2      

2:  from 'D:\testdata\testdata.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d:\error.txt

1:  bulk insert test      

2:  from 'D:\testdata\testdata.txt'      

3:  with      

4:  (fieldterminator=',',      

5:  rowterminator='\',      

6:  FIRSTROW =1,      

7:  LASTROW=3,      

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

9:  check_constraints)
