取n到m条记录的语句 1.
select top m * from tablename where id not in (select top n id from tablename) 2.
select top m * into 临时表(或表变量) from tablename order by columnname -- 将top m笔插入
set rowcount n
select * from 表变量 order by columnname desc 3.
select top n * from
(select top m * from tablename order by columnname) a
order by columnname desc
4.如果tablename里没有其他identity列,那么:
select identity(int) id0,* into #temp from tablename 取n到m条的语句为:
select * from #temp where id0 > =n and id0 <= m 如果你在执行select identity(int) id0,* into #temp from tablename这条语句的时候报错,那是因为你的DB中间的select into/bulkcopy属性没有打开要先执行:
exec sp_dboption 你的DB名字,'select into/bulkcopy',true
5.如果表里有identity属性,那么简单:
select * from tablename where identitycol between n and m
select top m * from tablename where id not in (select top n id from tablename) 2.
select top m * into 临时表(或表变量) from tablename order by columnname -- 将top m笔插入
set rowcount n
select * from 表变量 order by columnname desc 3.
select top n * from
(select top m * from tablename order by columnname) a
order by columnname desc
4.如果tablename里没有其他identity列,那么:
select identity(int) id0,* into #temp from tablename 取n到m条的语句为:
select * from #temp where id0 > =n and id0 <= m 如果你在执行select identity(int) id0,* into #temp from tablename这条语句的时候报错,那是因为你的DB中间的select into/bulkcopy属性没有打开要先执行:
exec sp_dboption 你的DB名字,'select into/bulkcopy',true
5.如果表里有identity属性,那么简单:
select * from tablename where identitycol between n and m
因为是写在程序里,所以必须一条语句解决。。
我用:
select top 8 * from (select top 24 EnterpriseID, EnterpriseName, [Address], AreaCode, Telephone, EditDate from [21yp_disk] where 1 = 1 and (EnterpriseName like '%关键字%' or Keyword like '%关键字%') order by EnterpriseID) order by EnterpriseID desc
会报错说:
消息 156,级别 15,状态 1,第 1 行
关键字 'order' 附近有语法错误。
同2,没有一句解决,而且大量用户搜索会生成太多临时表?
带条件的话identitycol还有用吗?
select top 8 * from (
select top 24 EnterpriseID, EnterpriseName, [Address], AreaCode, Telephone, EditDate from [21yp_disk]
where (EnterpriseName like '%关键字%' or Keyword like '%关键字%') order by EnterpriseID ) A
order by EnterpriseID desc
行不?
