Musisz utworzyć kursor, aby przejść przez zestaw rekordów.
Przykładowa tabela:
CREATE TABLE Customers
(
CustomerId INT NOT NULL PRIMARY KEY IDENTITY(1,1)
,FirstName Varchar(50)
,LastName VARCHAR(40)
)
INSERT INTO Customers VALUES('jane', 'doe')
INSERT INTO Customers VALUES('bob', 'smith')
Kursor:
DECLARE @CustomerId INT, @FirstName VARCHAR(30), @LastName VARCHAR(50)
DECLARE @MessageOutput VARCHAR(100)
DECLARE Customer_Cursor CURSOR FOR
SELECT CustomerId, FirstName, LastName FROM Customers
OPEN Customer_Cursor
FETCH NEXT FROM Customer_Cursor INTO
@CustomerId, @FirstName, @LastName
WHILE @@FETCH_STATUS = 0
BEGIN
SET @MessageOutput = @FirstName + ' ' + @LastName
RAISERROR(@MessageOutput,0,1) WITH NOWAIT
FETCH NEXT FROM Customer_Cursor INTO
@CustomerId, @FirstName, @LastName
END
CLOSE Customer_Cursor
DEALLOCATE Customer_Cursor
Oto link do MSDN, jak je tworzyć.

Dlatego użyłem Raise Error zamiast PRINT do wydruku.
