Error on an ANSI SQL Statement - sql

Question

select t2.s_studentreference
, t1.p_surname
, t1.p_forenames
, t3.e_reference
, t3.e_name
from capd_a t1
right outer join capd_b t2
on (t2.s_id = t1.p_id)
join capd_c t3
on ((t3.e_student=t1.p_id) and (t3.e_reference='D /YR2A2/12'))
I receive this error:
Syntax Error (Missing Operator) on (t2.s_id = t1.p_id)
join capd_c t3
on ((t3.e_student=t1.p_id) and (t3.e_reference='D /YR2A2/12'))
Any idea what is wrong with my query?

Answer 1

Access has a pervert version of SQL and not the ISO/ANSI standard. It really likes (read: requires) parenthesis when joining more than two tables. There are also restrictions on what types of joins (LEFT, RIGHT, INNER) are allowed inside parentheses:
from
( --- required
capd_a t1
INNER join capd_b t2 --- RIGHT join turned into INNER
on (t2.s_id = t1.p_id)
) --- required
INNER join capd_c t3
on ((t3.e_student=t1.p_id) and (t3.e_reference='D /YR2A2/12'))

Try building your query in the Access query designer. Coming from a different database system, you may not like the query designer much, but I'm suggesting you try it anyway because it will help you create SQL which the Access db engine can accept.
Among the differences you're facing are:
Access requires parentheses when your query includes more that 2 data sources, and is very demanding about their positions.
The db engine does not recognize JOIN as a synonym for INNER JOIN. You must always specify the join type (INNER; LEFT; or RIGHT).
The engine will accept RIGHT OUTER JOIN, but the query designer will change it to just RIGHT JOIN. So it doesn't really make a difference, but I mentioned it only to avoid confusion.
If you can't tolerate the query designer, I'll offer this as a starting point.
select t2.s_studentreference
, t1.p_surname
, t1.p_forenames
, t3.e_reference
, t3.e_name
from (capd_a t1
inner join capd_b t2
on t2.s_id = t1.p_id)
inner join capd_c t3
on t3.e_student=t1.p_id
where t3.e_reference='D /YR2A2/12'
I user inner join both times because in certain situations Access balks with LEFT or RIGHT joins and INNER joins in the same query. I'm uncertain whether your RIGHT join would be a problem in this case, but both as INNER will surely work. So first get all the rest of the query syntax working correctly, then revise your join types as needed.
I moved t3.e_reference='D /YR2A2/12' from the ON to a WHERE clause. That's my preference, but I don't think it will make a difference either way.

Answer 3

As your query includes t3.e_reference='D /YR22/A12' in ON statement scope which should be excluded from ON statement scope and write it seperately outside the ON statement scope......
You can do like this;
select t2.s_studentreference
, t1.p_surname
, t1.p_forenames
, t3.e_reference
, t3.e_name
from capd_a t1
right outer join capd_b t2
on (t2.s_id = t1.p_id)
join capd_c t3
on (t3.e_student=t1.p_id)
and (t3.e_reference='D /YR2A2/12')
Or, you can do use WHERE clause in query:
SELECT t2.s_studentreference
, t1.p_surname
, t1.p_forenames
, t3.e_reference
, t3.e_name
FROM capd_a t1
RIGHT OUTER JOIN capd_b t2
ON (t2.s_id = t1.p_id)
JOIN capd_c t3
ON (t3.e_student = t1.p_id)
WHERE t3.e_reference='D /YR2A2/12'
