`t3`.`y`;
Table `t3` won't have any indices, even if table `t2` does, is that correct?
(Assume that the sub-select is really much more complicated that my
example.) Wouldn't it be a lot faster to replace the sub-select with a
temporary table that does have a key on `y`?

Hi list,
does MySQL accept a SELECT inside another SELECT, like this:
SELECT t.Trial_ID_Code AS Trial,
CONCAT(s.Site_Primary_Investigator_Title, " ",
s.Site_Primary_Investigator_Last_Name) AS 'Investigator',
CONCAT(sc.Site_ID_Number, "-", s.Site_ID_Code, "-", sc.Scanner_ID_Number)

I am using version 3.23.58 and need to do

select * from a where id not in (select tbl_id from b where tbl="a");
Given that my version does not support sub selects, how
