SQL Server自动生成INSERT语句

这是建立一个存储过程，通过执行这个存储过程，将指定的数据表中的数据导成Insert语句形式

--这是一个可以将表中的数据自动生成INSERT语句的存储过程

--有个BUG，如果是自动增长列，数据也会被插入

--在查询分析器中执行完成后，可以从执行结果中自制出SQL脚本。

IF OBJECT_ID('spGenInsertSQL','P') IS NOT NULL

DROP PROC spGenInsertSQL

GO

CREATE proc spGenInsertSQL (@tablename varchar(256))

as

begin

declare @sql varchar(8000)

declare @sqlValues varchar(8000)

set @sql =' ('

set @sqlValues = 'values (''+'

select @sqlValues = @sqlValues + cols + ' + '','' + ' ,@sql = @sql + '[' + name + '],'

from

(select case

when xtype in (48,52,56,59,60,62,104,106,108,122,127)

then 'case when '+ name +' is null then ''NULL'' else ' + 'cast('+ name + ' as varchar)'+' end'

when xtype in (58,61)

then 'case when '+ name +'

else '''NULL'''

end as Cols,name

from syscolumns

where id = object_id(@tablename)

) T

set @sql ='select ''INSERT INTO ['+ @tablename + ']' +
left(@sql,len(@sql)-1)+') ' + left(@sqlValues,len(@sqlValues)-4) + ')''
from '+@tablename

print @sql

exec (@sql)

end

GO

执行如下语句测试结果：

exec spGenInsertSQL test
