sql server - SQL Select Return Default Value If Null -


database: ms sql 2008

select listing.title, listing.mls, pictures.pictureth, pictures.picture, listing.id  listing inner join pictures on listing.id = pictures.listingid (pictures.id = (select min(id) pictures (listingid = listing.id))) 

the issue is, have several "listings" without picture, , because of sql script don't show up. how can them show up?

maybe give pictures.picture column value of "default.jpg" if value null? i'm pretty lost on this, if help, that'd amazing. sorry if i'm asking question poorly well, dont understand how ask need do. ask more details , i'll post them.

each listing can have many pictures user wants, need script display listing if doesn't have picture.


phase 2


thank all. far i'm learning new commands never knew existed. issue returning row each picture listing has. default image working great.

select listing.title, listing.mls, coalesce(pictures.pictureth, '../default_th.jpg') pictureth, coalesce(pictures.picture, '../default.jpg') picture, listing.id listing left outer join pictures on listing.id = pictures.listingid 

how can returns 1 row per listingid ?

two things:

  1. use left outer join instead of inner join listings, missing pictures.
  2. use coalesce apply default

    select listing.title     , listing.mls     , pictures.pictureth     , coalesce(pictures.picture, 'default.jpg') picture     , listing.id   listing  left outer join pictures      on listing.id = pictures.listingid  

edit limit 1 row:

select listing.title     , listing.mls     , pictures.pictureth     , coalesce(pictures.picture, 'default.jpg') picture     , listing.id   listing  left outer join pictures      on listing.id = pictures.listingid  pictures.id null or pictures.id = (select min(id)      pictures      (listingid = listing.id)))
