Question

I need to check if the user has access based on their roles. (ASP.NET and SQL Server)

SELECT rf.ReadAccess
FROM aspnet_Users as u INNER JOIN aspnet_Roles as r ON r.UserID=u.UserID
INNER JOIN RolesByForm as rf ON rf.RoleID=r.RoleID
WHERE u.UserID=@UserID

So this gets me close, but this is what I really want. I want forms visible by default, so if there is no record in RolesByForm, it should be “True”. But if there is a record it should return based on the ReadAccess field.

How do I get the query to return a Boolean?

Answer 1

SELECT ReadAccess=CASE rf.ReadAccess WHEN 1 THEN 'True' ELSE 'False' END
FROM aspnet_Users as u INNER JOIN aspnet_Roles as r ON r.UserID=u.UserID
INNER JOIN RolesByForm as rf ON rf.RoleID=r.RoleID
WHERE u.UserID=@UserID

And in your .net code write something like:

bool result;
bool myBoolean=Boolean.TryParse(dataset["ReadAccess"], out result);
