Here's the correct syntax :
SELECT SECTION.SECTION_PK, SECTION.SECTION_NAME, SECTION.BRAND_1_FK, SECTION.BRAND_2_FK, b1.BRAND_NAME, b2.BRAND_NAME
FROM SECTION left outer join BRAND as b1 on b1.BRAND_PK =BRAND_1_FK left outer join BRAND as b2 on b2.BRAND_PK =BRAND_2_FK

Hello,
I have two tables SECTION and BRAND. SECTION is related to BRAND via two foreign keys. I would like to select ALL SECTIONs whether the FKs are null or not and fetch the BRAND attributes in one SQL statement. In other words I need a double outer join.
Is this possible at all?
The following doesn't work for two reasons: a) Table name "brand" specified more than once. b) how would I specify the same output columns twice?
SELECT SECTION.SECTION_PK, SECTION.SECTION_NAME, SECTION.BRAND_1_FK, SECTION.BRAND_2_FK, BRAND.BRAND_PK, BRAND.BRAND_NAME
FROM SECTION left outer join BRAND on BRAND_PK =BRAND_1_FK left outer join BRAND on BRAND_PK =BRAND_2_FK
I don't know if this will solve your specific problem, but you can use the same table twice in the same query by using aliases, something like this (untested of course)
SELECT SECTION.SECTION_PK, SECTION.SECTION_NAME, SECTION.BRAND_1_FK, SECTION.BRAND_2_FK, a.BRAND_PK, a.BRAND_NAME b.BRAND_PK, b.BRAND_NAME
FROM SECTION left outer join BRAND a on BRAND_PK =BRAND_1_FK left outer join BRAND b on BRAND_PK =BRAND_2_FK
