For an example of using NEXT VALUE FOR in a CREATE TABLE statement, see Example CSequence Numbers. My Table ( IDColumn nvarchar(25) PRIMARY KEY, name varchar(25) NOT NULL ) ; GO CREATE SEQUENCE Test.Counter Seq AS int START WITH 1 INCREMENT BY 1 ; GO ALTER TABLE Test.Generates a sequence number from the specified sequence object.
Test Table (Counter Column, Name) VALUES (NEXT VALUE FOR Test.A PL/SQL Block consists of three sections: Declaration Section: This section is optional and it starts with the reserved keyword DECLARE.This section is used to declare any placeholders like variables, constants, records and cursors, which are used to manipulate data in the execution section.For more information, see OVER Clause (Transact-SQL). The NEXT VALUE FOR function can be used in stored procedures and triggers.When the NEXT VALUE FOR function is used in a query or default constraint, if the same sequence object is used more than once, or if the same sequence object is used both in the statement supplying the values, and in a default constraint being executed, the same value will be returned for all columns referencing the same sequence within a row in the result set.Count By1, ' Syed') ; GO SELECT * FROM Test.Test Table; GO Note The feedback system for this content will be changing soon.

Count By1 ; SELECT @myvar1 AS myvar1, @myvar2 AS myvar2, @myvar3 AS myvar3 ; GO Using the NEXT VALUE FOR function in the definition of a default constraint is supported.
