SQL Server自动生成INSERT语句(在SQL2005下测试通过)

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

               when xtype in (167)

                     then 'case when '+ name +' is null then ''NULL'' else '+''''''''' + ' + 'replace('+ name+','''''''','''''''''''')' + '+'''''''''+' end'

                when xtype in (231)

                     then 'case when '+ name +' is null then ''NULL'' else '+'''N'''''' + ' + 'replace('+ name+','''''''','''''''''''')' + '+'''''''''+' end'

                when xtype in (175)

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

                when xtype in (239)

                     then 'case when '+ name +' is null then ''NULL'' else '+'''N'''''' + ' + 'cast(replace('+ name+','''''''','''''''''''') as Char(' + cast(length as varchar)  + '))+'''''''''+' end'

                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
