SQL Group result with specific criteria -


i need select , group id's of conditionid values 1

   id     conditionid     2       0     2       1     2       0     3       0     3       0     4       1     4       1

the result should be:

id     conditionid              4       1

how can this?

this can done checking if row count per id equals row count of conditionid = 1 per id, in table.

select id tablename group id having count(*) = count(case when conditionid = 1 1 end)
