. Ident_current can return identity values generated for a particular table in any session and in any scope.

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 th

illustrates two scopes: one is an insert on T1 and the other is an insert on T2 as the result of a trigger.Assuming that both T1 and T2 have an IDENTITY column, @ @IDENTITY and scope_identity will return different values at the end of the INSERT statement on T1.@ @IDENTITY returns the last IDENTITY column value insert

column inserted to any scope in the current session. This value is the value inserted in T2. Scope_identity () returns the identity value inserted in T1, which is the last insert that occurs in the same scope. If the scope_identity () function is called when an insert statement occurs in the scope before the identifiers column, the function returns NULL. The values returned by ident_current ('t1') and ident_current ('t2') are the last auto-increment
