which each owner select a group and enter 3 choice, now i want to find the owner who select shapes and entered circle and star.

it must return owner id = 3

Answer 1

Assuming that group and model are unique for every owner

SELECT  a.owner
FROM    tableName a
WHERE   a.[group] = 'shapes' AND
        a.model IN ('circle','star')
GROUP   BY a.owner
HAVING  COUNT(*) = 2

otherwise, you need to uniquely count the number of model

SELECT  a.owner
FROM    tableName a
WHERE   a.[group] = 'shapes' AND
        a.model IN ('circle','star')
GROUP   BY a.owner
HAVING  COUNT(DISTINCT a.model) = 2
