SQL Server DB Design Guidelines
... For scalable applications you have to stay stateless. Do -not- use server side cursors, or components that create server side cursors, at all. They’re too resource intensive to scale. For server side looping try “while” loops on (small) table variables w/identities instead (v2k). For more large or c ...
