SqlServer timestamp数据类型

--时间戳类型和bigint互相转化示例:
  set nocount on
  --申明3个时间戳
  declare @timeFlag1
bigint
  declare @timeFlag2 bigint
  declare @timeFlag3
bigint
  --建立表,timestamp类型不需要字段名
  create table test(timestamp,a
int)
  --插入1 记录时间戳,@@dbts为数据库时间戳
  insert into test select null,1
  set
@timeFlag1=cast(@@dbts as bigint)
  --插入2 记录时间戳
  insert into test select
null,2
  set @timeFlag2=cast(@@dbts as bigint)
  --更新3 记录时间戳
  update
test set a=3 where a=2
  set @timeFlag3=cast(@@dbts as
bigint)
  --时间戳1的记录
  select *from test where timestamp=cast(@timeFlag1 as
varbinary(8))
  --时间戳2的记录已经不存在了
  select *from test where
timestamp=cast(@timeFlag2 as varbinary(8))
  --时间戳3的记录
  select *from test
where timestamp=cast(@timeFlag3 as varbinary(8))
