âThat meant representation for all.â. Since then, the best of North Carolinaâs legislative leaders, though not all, have presided over its chambers with an eye toward good government. But last weekâs session was a reversion to the strong-arm rule that Republicans decried in the 1980s.
An identity function is a function that always returns the same value as its argument. In other words, the identity function is the function f(x) = x. x.
SCOPE_IDENTITY, IDENT_CURRENT, and @@IDENTITY are similar functions because they return values that are inserted into identity columns. IDENT_CURRENT is not limited by scope and session; it is limited to a specified table. IDENT_CURRENT returns the value generated for a specific table in any session and any scope.f you insert a row into the table, @@IDENTITY and SCOPE_IDENTITY() return different values. SCOPE_IDENTITY() returns the value from the insert into the user table, whereas @@IDENTITY returns the value from the insert into the replication system table.
