sql-server-2005 - loweredrolename in aspnet_users table (SQL Server 2005)

Question

For my existing data, both RoleName and LoweredRoleName are same, but some are lower case and some are in same case too.

Anyone knows what is the use of column LoweredRoleName in aspnet_users table?

Answer 1

他们是一样的。我认为由.net在内部使用。也许LoweredRoleName 用于避免使用SQL 的LOWER()函数。

Answer 2

我敢肯定它是有原因的，在风口浪尖上它似乎是多余的和设计的味道。
