Sybase数据库，普通表修改分区表步骤
2024-08-28 21:27:30
本文目标：指导项目侧人员再遇到此类改动需求时可以自己参照更改。
需求：Sybase数据库，普通表t_jingyu修改为按天分区的分区表。
需求：Sybase数据库，普通表t_jingyu修改为按天分区的分区表。
1.sp_help查看t_jingyu的表结构，索引等信息
sp_help t_jingyu
go
提示：可以直接用DBArtisan工具Extract原建表语句参考
2.sp_rename重命名普通表t_jingyu及其主键pk_t_jingyu和索引idx_t_jingyu_1。
sp_rename t_jingyu,t_jingyu_bak
go
sp_rename "t_jingyu_bak.pk_t_jingyu",pk_t_jingyu_bak
go
sp_rename "t_jingyu_bak.idx_t_jingyu_1",idx_t_jingyu_1_bak
go
3.确定上面备份无问题后，创建分区表t_jingyu,分区索引。
3.1创建分区表t_jingyu
3.1创建分区表t_jingyu
CREATE TABLE dbo.t_jingyu
(
oid varchar(64) NOT NULL,
related_rnc varchar(64) NULL,
start_time datetime NOT NULL
)
LOCK DATAROWS
PARTITION BY RANGE (start_time)

p20140609 VALUES <= ('2014-06-09 23:59:59.999') ON seg_d_wrnop,
p20140610 VALUES <= ('2014-06-10 23:59:59.999') ON seg_d_wrnop,
p20140611 VALUES <= ('2014-06-11 23:59:59.999') ON seg_d_wrnop,
p20140612 VALUES <= ('2014-06-12 23:59:59.999') ON seg_d_wrnop,
p20140613 VALUES <= ('2014-06-13 23:59:59.999') ON seg_d_wrnop,

p20140617 VALUES <= ('2014-06-17 23:59:59.999') ON seg_d_wrnop,
p20140618 VALUES <= ('2014-06-18 23:59:59.999') ON seg_d_wrnop,
p20140619 VALUES <= ('2014-06-19 23:59:59.999') ON seg_d_wrnop,
p20140620 VALUES <= ('2014-06-20 23:59:59.999') ON seg_d_wrnop,
p20140621 VALUES <= ('2014-06-21 23:59:59.999') ON seg_d_wrnop,
p20140622 VALUES <= ('2014-06-22 23:59:59.999') ON seg_d_wrnop,
p20140623 VALUES <= ('2014-06-23 23:59:59.999') ON seg_d_wrnop,
p20140624 VALUES <= ('2014-06-24 23:59:59.999') ON seg_d_wrnop,
p20140625 VALUES <= ('2014-06-25 23:59:59.999') ON seg_d_wrnop,
p20140626 VALUES <= ('2014-06-26 23:59:59.999') ON seg_d_wrnop,
p20140627 VALUES <= ('2014-06-27 23:59:59.999') ON seg_d_wrnop,
p20140628 VALUES <= ('2014-06-28 23:59:59.999') ON seg_d_wrnop,
p20140629 VALUES <= ('2014-06-29 23:59:59.999') ON seg_d_wrnop,
p20140630 VALUES <= ('2014-06-30 23:59:59.999') ON seg_d_wrnop)
go
3.2创建惟一性非聚簇分区索引(代替了原表主键的作用)
CREATE UNIQUE NONCLUSTERED INDEX pk_t_jingyu
ON dbo.t_jingyu(oid,start_time)
ON seg_i_wrnop
LOCAL INDEX
go
3.3创建其他非聚簇分区索引
CREATE NONCLUSTERED INDEX idx_t_jingyu_1
ON dbo.t_jingyu(start_time,related_rnc)
ON seg_i_wrnop
LOCAL INDEX
go
4.选择性插入需要的数据到新表
insert into t_jingyu select * from t_jingyu_bak where 条件
go
