  • SQL Server 存储过程生成insert语句

    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

    Create   proc [dbo].[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 '''''''''+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 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
    SQL语句

    最后的结果:

    INSERT INTO [SysSample] ([Id],[Name],[Age],[Bir],[Photo],[Note],[CreateTime]) values ('0002CA83-AF2F-4D8F-A345-33CA1CC7CF3C','任务调度系统',18,'2013-01-02 21:42:30.013','',NULL,'2013-01-02 21:42:30.013')
    INSERT INTO [SysSample] ([Id],[Name],[Age],[Bir],[Photo],[Note],[CreateTime]) values ('0004A6F3-EC28-4D1F-BA40-0FC4B2218C92','任务调度系统',18,'2013-07-09 19:36:00.060','',NULL,'2013-07-09 19:36:00.060')
