Microsoft SQL Server Last Inserted Identity @@IDENTITY
Example
CREATE TABLE dbo.logging_table(log_id INT IDENTITY(1,1) PRIMARY KEY,
log_message VARCHAR(255))
CREATE TABLE dbo.person(person_id INT IDENTITY(1,1) PRIMARY KEY,
person_name VARCHAR(100) NOT NULL)
GO;
CREATE TRIGGER dbo.InsertToADifferentTable ON dbo.person
AFTER INSERT
AS
INSERT INTO dbo.logging_table(log_message)
VALUES('Someone added something to the person table')
GO;
INSERT INTO dbo.person(person_name)
VALUES('John Doe')
SELECT @@IDENTITY;
This will return the most recently-added identity on the same connection, regardless of scope. In this case, whatever the current value of the identity column on logging_table is, assuming no other activity is occurring on the instance of SQL Server and no other triggers fire from this insert.
