Eu am confundat putin "collation" cu "collation setting" cred despre care in ghidul de studiu pentru 70-431 de la Sybex se zice:
"once you have installed SQL Server, you cannot change the collation setting. To change it, you must reinstall SQL Server and rebuild all your databases. So, choose wisely; it is usually best to use the default sort setting of case insensitivity and build sensitivity into your applications if you need it."
Si cu collation de baza de date m-am tot jucat, si in general a mers bine si fara probleme.
