Which solution is better for general performance ?
LEFT JOIN (A)
FROM TABLEA LEFT JOIN TABLEB on TABLEA.id=TABLEB=id;
Thank you for your answer
Have a good day

It is usually better to do it on QV. This way you will not impact the performance of the SQL server.
Instead of using joins try using Mapping Load and ApplyMap(). It is way faster than doing joins and for your example it works perfectly:
Don't join - use Applymap instead
I would use sql join instead of QV if the tables are huge, it would give better performance. It all depends on the table sizes
