My quick question is, what is the most efficient way to write this query?
select T1.Column1, T1.Column2, T2.Column3, T2.Column4, T2.Column5
from Table1 as T1
join Table2 T2 on T1.Column1 = T2.Column1
where T1.Column1 in (select distinct Column1 from Table3)
This is how I solved my problem, but I want to know if it's technically correct. Thanks!
