if object_id('[pactinfo]') is not null

drop table [pactinfo]

go create table [pactinfo]([id] int,[pactname] varchar(4))

insert [pactinfo] select 1,'正常' union all select 2,'中國' union all select 3,'做飯'

union all select 4,'加發'

---查詢---

select * from [pactinfo] where left(dbo.f_getpy(pactname),1)='z'

select * from pactinfo where dbo.f_getpy(pactname) like '%z%'

--結果--- id pactname -----------
