SQL Server存储过程生成insert语句实例

  你肯定有过这样的烦恼,同样的表,不同的数据库,加入你不能执行select insert
  那么你肯定需要一条这样的存储过程,之需要传入表明,就会给你生成数据的插入语句。
  当然数据表数量太大,你将最好用别的方式
  代码如下:
Create   proc . (@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 '''''''''+convert(char(23),'+name+',121)+''''''''' --datetime
  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>  ) T
  
set @sql ='select ''INSERT INTO ['+ @tablename + ']' + left(@sql,len(@sql)-1)+') ' + left(@sqlValues,len(@sqlValues)-4) + ')'' from '+@tablename
  
print @sql
  
exec (@sql)
  
end
  
SQL语句
  最后的结果:
