  • 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

    PS:自增列需要调整一下
    参考 SET   IDENTITY_INSERT   表名   ON

    SET   IDENTITY_INSERT   表名   OFF
