Label:MSDN to the official explanation: These three functions all return the last generated identity value. However, the "last" scope and the session defined in each of these functions are different. 1. Ident_current returns the most recent identity value generated for a session and the specified table in the current scope. If the Ident_current value is NULL (because the table never contains rows or has bee
The ASP. NET core identity is the membership system for building an ASP. NET core Web application, including membership , login, and user data storage

I. BACKGROUND
The ID field in table A in the SQL Server database is defined as: [ID] [int] IDENTITY (1,1), and as the data grows, the ID value is close to 2147483647 (int's range is:-2 147 483 648 to 2 147 483 647) , although the old data has been archived, but this table needs to keep the most recent 100 million data, what is the method to solve the problem of the explosion of ID value?
There are two ways to solve the problem: one is to modify the

SQL Server 2000 has three similar functions: scope_identity, ident_current, and @ identity. Both return values inserted into the identity column.Nbsp; ident_current returns the final id value generated for any session and a specific table in any scope. Ident_current is not restricted by the scope and session, but by the specified table. Ident_current returns the value generated for a specific table in any s
