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。

1.sp_help查看t_jingyu的表结构,索引等信息
1
2
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。

3.2创建惟一性非聚簇分区索引(代替了原表主键的作用)

5
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

3
4
5
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
