Question

I am using SQL Server 2008 R2

As you can see on image NOID 29 already taken by LIB_TOURNE 1, how can i neglect the NOID 29 that taken by LIB_TOURNE 2

so when NOID with date X is unique. NOID 29 with date 2012-09-27 11:47:52.000 only appear once time.

Thanks you in advance,
Stev

PS : i have try also:

SELECT DISTINCT * FROM LETTRE_VOIT_FINAL LEFT JOIN TOURNE ON
LETTRE_VOIT_FINAL.INSEE_DEST = TOURNE.NO_INSEE AND TYPE_TOURNE =
MODE_LIV order by TOURNE.LIB_TOURNE

Answer 1

You can do this with a group by:

select min(lib_tourne), <all columns but lib_tourne>
from (<your query here>) t
group by <all columns but lib_tourne>
