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
