利用sql 存储过程把表中内容自动生成insert语句-优快云博客

选中所在数据库

执行创建存储过程的sql

CREATE proc [dbo].[spGenInsertSQL] (@tablename nvarchar(256),@sqlwhere varchar(4000))
as
begin
declare @sql varchar(max)
declare @sqlValues varchar(max)
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  'coalesce(cast('+ name + ' as varchar),''null'')'

                when xtype in (58,61)

                     then '''''''''+coalesce(convert(varchar,'+ name +',121),''null'')+'''''''''

               when xtype in (167)
                     then '''''''''+coalesce('+name+',''null'')+'''''''''
                    -- then 'case when '+ name +' is null then ''NULL'' else '+''''''''' + ' + 'replace('+ name+','''''''','''''''''''')' + '+'''''''''+' end'

                when xtype in (231,239,175)
                    then '''''''''+coalesce('+name+',''null'')+'''''''''
                    --- then 'case when '+ name +' is null then ''NULL'' else '+''''''''' + ' + '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 '+''''''''' + ' + '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 replace(''INSERT INTO '+ @tablename + '' + left(@sql,len(@sql)-1)+') ' + left(@sqlValues,len(@sqlValues)-4) + ');'',''''''null'''''',''null'') from '+@tablename+@sqlwhere
print @sql
PRINT len(@SQL)
exec (@sql)
end

GO

　　执行存储过程

exec [spGenInsertSQL] @tablename='RoomConfig',@sqlwhere=''

　　上面RoomConfig是我库中一个表，在我使用的sql 2008中上面语句会报错找不到存储过程，可以不用管他
