Table1
Name:
-----
Paul
Ringo
John
Paul
George
Ringo

Table2
Name
------
Steve
George
Peter
Paul
John
George

I want all those records from Table1 who's names are not in the List of Table2; in this case the wanted result is

Ringo
Ringo

how can I achieve this?

select name from table1 as t1
where not exists(select * from table2 as t2 where t1.name=t2.name)

@SwePeso: This query just returns one "Ringo" - I need all the records from Table1, that do not exist in Table2

@Webfred: I can't adapt the syntax to my query as table1 is a inner join relationship... :( Could save it as a new table and refer to it that way, but I rather learn how to do this in one expression.

table1:
select * from table1 inner join table3 on table1.xx = table3.xx

So in application to your query I try:

select * from table1 inner join table3 on table1.xx = table3.xx as t1
where not exists(select * from table2 as t2 where t1.name=t2.name)

Incorrect syntax near the keyword 'as'

hmmm... Martin

you can use like


select t1.*
from
(
select * from table1 inner join table3 on table1.xx = table3.xx
) as t1
where not exists(select * from table2 as t2 where t1.name=t2.name)

SELECT * FROM table1 LEFT JOIN table2 ON table1.Name = table2.Name WHERE table2.Name IS NULL
