sql中创建主键非聚集索引和聚集索引
--排序(聚集索引)
create clustered index inx_entry_stock_bi on entry_stock_d(entry_stock_bi)
--创建非聚集索引
create nonclustered index inx_entry_stock_on entry_stock_d(entry_stock_bi)
--主键
alter table entry_stock_d add primary key nonclustered--主键且非聚集
(
entry_stock_bi,aid
)
select * from sysobjects where parent_obj in(select id from sysobjects where xtype='U' and name='saleticket_currency_d')
alter table saleticket_currency_d drop constraint PK__saleticket_curre__1F8E9120
alter table saleticket_currency_d alter column card_id varchar(20) not null
alter table saleticket_currency_d add constraint PK__saleticket_curre__1F8E9120 primary key nonclustered(saleticket_bi,currency_id,card_id)
create clustered index pk__tb_d_seq on tb_d(tab_id,seq)
