我想補充LTRIM這個查詢，使我得到了數據室內用LTRIM也不同

Question

**speciality** 
---name 
--name 
-name 

因此它不會給我不同的值，由於空間（ - ）如何使用LTRIM

select distinct split.a.value('.','varchar(100)')as string from (select cast ('<M>' + replace(speciality, ',', '</M><M>') + '</M>' as xml) as string from health where type='Doctor' and speciality like '%dentist%') as a cross apply String.nodes ('/M') as split(a) 

Answer 1

使用REPLACE：

DEMO

select distinct REPLACE(split.a.value('.','varchar(100)'), '-', '') as string 
from (select cast ('<M>' + replace(speciality, ',', '</M><M>') + '</M>' as xml) as string 
     from health 
     where type='Doctor' 
     and speciality like '%dentist%') as a 
cross apply String.nodes ('/M') as split(a) 

，或者如果你的數據是：

**speciality** 
    name 
    name 
name 

使用只是LTRIM：

select distinct LTRIM(split.a.value('.','varchar(100)')) as string 
from (select cast ('<M>' + replace(speciality, ',', '</M><M>') + '</M>' as xml) as string 
      from health 
      where type='Doctor' 
      and speciality like '%dentist%') as a 
cross apply String.nodes ('/M') as split(a)
