I need to do a sql query in MS Access.
But I got error in MS Access:
SELECT *
FROM
(
SELECT *
FROM table1
where not exists
(
SELECT *
FROM table2
where table2.id = table1.id
) as t
) as t1, table3
where table3.id = t1.id
Syntax error: (missing operator) in query expression 'not exists ( ... ) as t'
Any help would be appreciated.
The not exists subselect does not require an alias. Note that I've removed the as t
SELECT *
FROM
(
SELECT *
FROM table1
where not exists
(
SELECT *
FROM table2
where table2.id = table1.id
)
) as t1, table3
where table3.id = t1.id
You might also consider using an inner join and a left join to get rid of your not exists:
This should be exactly equivalent of the above:
SELECT t1.*, t3.*
FROM
table1 t1
inner join table3 t3 on t1.id = t3.id
left join table2 t2 on t1.id = t2.id
where
t2.id is null
