首先，必须将数据插入到某些临时表中. 这里是几种方式.然后运行以下查询:

First, you must insert your data to some temp table. Here are several ways. Then run this query:

with cte as (
select 
    company, replace(replace(replace(accounts,'(',''),')',''),'+','')+'#' accounts 
from 
    (values ('company 1','#3000#3999'),('company 2','(#4000#4019)+(#4021#4024)')) data(company, accounts)
)
, rcte as (
    select 
        company, stuff(accounts, ind1, ind2 - ind1, '') acc, substring(accounts, ind1 + 1, ind2 - ind1 - 1) accounts
    from 
        cte
        cross apply (select charindex('#', accounts) ind1) ca
        cross apply (select charindex('#', accounts, ind1 + 1) ind2) cb
    union all
    select
        company, stuff(acc, ind1, ind2 - ind1, ''), substring(acc, ind1 + 1, ind2 - ind1 - 1)
    from
        rcte
        cross apply (select charindex('#', acc) ind1) ca
        cross apply (select charindex('#', acc, ind1 + 1) ind2) cb
    where
        len(acc)>1
)

select company, accounts from rcte
order by company, accounts
