SqlServer的timestamp数据类型2009-12-03 Csdn 贾涛--时间戳类型和bigint互相转化示例:by jinjazzset 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))--删除表 drop table test set nocount off/**//*--测试结果 timestamp a ------------------ ----------- 0x000000000000B553 1timestamp a ------------------ -----------timestamp a ------------------ ----------- 0x000000000000B555 3 */
