Nested SELECT HELP....

[Grigore Marinescu]

Hi all,
I have the following databasedesign :

https://www.marinescu.dk/databasedesign.pdf

which i have a nested SELECT on but i need some more information which i
don't know how to retrieve. I have the following SELECT :

SELECT DISTINCT Resource.Resour ceID, Localized.Resou rceValue,
Localized.Font, Resource.Resour ceName, Resource.Commen t, Type.TypeName FROM
Localized, Resource,Type WHERE Localized.Resou rceID = Resource.Resour ceID
AND Resource.TypeID = Type.TypeID ORDER BY Resource.Resour ceID

For some Resources there are Rules. I will like to have a new column named
RulesText in my query where there will be shown the RuleText if there is any
for that particular Resource.

Could anybody help me here ????

Best Regards
Mihai Marinescu

Re: Nested SELECT HELP....

SELECT DISTINCT
R.ResourceID, L.ResourceValue , L.Font, R.ResourceName, R.Comment,
T.TypeName, RL.RuleText
FROM Localized AS L
JOIN Resource AS R ON L.ResourceID = R.ResourceID
JOIN Type AS T ON R.TypeID = T.TypeID
LEFT JOIN ResourceRule AS RR ON RR.resourceid = R.resourceid
LEFT JOIN Rules AS RL ON RL.ruleid = RR.ruleid
ORDER BY R.ResourceID

(untested)
