Left join with condition

Question

Suppose I have these tables

create table bug (
    id int primary key, 
    name varchar(20)
)
create table blocking (
    pk int primary key,
    id int, 
          


        

Answer 1

Simply put the "qa bug" criteria in the join:

select t1.*, t2.name from #bug t1 
left join #blocking t2 on t1.id = t2.id AND t2.name = 'qa bug'
