I have a question regarding a left join. I have two tables which look like this:
I now want to join the information from table 2 to my first table but I would only need info3 once so that my final table looks like this:
By simply coding this:
create table test as
select a.*, b.info3
from table1 as a
left join table2 as b
I get several duplicate rows. I guess I have to distinct the join somewhere, but I am not sure how.
Thank you for your help.
