I have a strict limitation - I need to create a SQL view that executes a portion of the where clause conditionally.
In an ideal world I'd be using Java or .Net to validation my condition and then choose one of two views. However, I do not have that luxery.
Suppose I currently have a view:
Select ORG_ID, ORG_NAME, SERVICE_DESCR From ServiceOrderTbl Where Status='O'
Now some users have restrictions - but not all users
So my pseudo code looks something like:
if (Select count(*) from SecurityRestrictionsTbl where oprid='User1')>0 Then
Select ORG_ID, ORG_NAME, SERVICE_DESCR From ServiceOrderTbl Where Status='O' AND ORG_ID in (Select org_id from SecurityRestrictionsTbl where oprid='User1')
else
Select ORG_ID, ORG_NAME, SERVICE_DESCR From ServiceOrderTbl Where Status='O'
end
So you see, the restrictions table only has user accounts that are restricted - if the user does not exist in the table, then I need to return all results.
And all of this needs to be done within a view.
Other options are to create a stored procedure and/or a function that does the same thing.... but then those results need to be pulled from the aforementioned view
