SQL-’08：多个Replace语句是不好的做法/还有另一种写这个查询的

Select 
Distinct 
    REPLACE(REPLACE(REPLACE(REPLACE(Category,' & ','-'),'/',',' ','-') AS Department 
From 
     Inv WITH(NOLOCK)

我很想知道由于我是一名小型ETL工程师,并但愿养成精采的风俗.

显然,在很多环境下,这也许会变得更长.

办理要领

declare @Category varchar(25)
    set @Category = 'ABC & DEF/GHI,LMN OP'
    -- nested replace
    select replace(replace(replace(replace(@Category,'-') as Department 

    -- table driven
    declare @t table (ReplaceThis varchar(10),WithThis varchar(10))
    insert into @t
        values  (' & ',('/',(',(' ','-')

    select  @Category = replace(@Category,ReplaceThis,isnull(WithThis,''))                       
    from    @t
    where   charindex(ReplaceThis,@Category) > 0;

    select @Category [Department]
