Select 满足某个条件时只有一行？

Question

ID	NAME	DATE	STATUS
1	Joe	01-22	Approved
1	Joe	01-22	Pending
2	Bill	02-22	Approved
2	Bill	02-22	Sent back
3	John	01-22	Approved
4	Bob	02-22	Pending

How do I only return one row per ID, placing priority on approved?

Example: for Id 1 I only want the row that is approved and not the one that is pending.

Some Id's may only have 1 record for example ID 4 has just one record and is pending.

What I want is: IF status = approved and pending for the same Id then keep the approved record and not select the pending record

If status = pending then keep that record

Answer 1

This will preferentially select Approved, then Pending, then everything else. If you don't want "everything else" just filter in the WHERE clause.

select id,
       name,
       date,
       status
  from (
        select *,
               row_number() over 
                 ( partition by id
                       order by case when status = 'Approved' then 1
                                     when status = 'Pending' then 2
                                     else 3
                                 end asc,
                                date
                 ) as first_by_date_with_approved_precedence
          from your_table
       ) tmp
 where first_by_date_with_approved_precedence = 1

Answer 2

It could also be as easy as the following (provided status is not blank or null)

Select Top 1 with ties * 
 from  YourTable
 order by row_number() over (partition by id order by Status)

Results

ID  NAME    DATE    STATUS
1   Joe     01-22   Approved
2   Bill    02-22   Approved
3   John    01-22   Approved
4   Bob     02-22   Pending
