Get Multiple Values in SQL Server Cursor

问题

I have a cursor containing several columns from the row it brings back that I would like to process at once. I notice most of the examples I've seeing on how to use cursors show them assigning a particular column from the cursor to a scalar value one at a time, then moving to the next row,

e.g.

OPEN db_cursor  
FETCH NEXT FROM db_cursor INTO @name  

WHILE @@FETCH_STATUS = 0  
BEGIN  
       --Do Stuff with @name scalar value, then get next row from cursor

       FETCH NEXT FROM db_cursor INTO @name  
END

What I want to know is if it's possible to do something like the following:

    OPEN db_cursor  
    FETCH NEXT FROM db_cursor; 

    WHILE @@FETCH_STATUS = 0  
    BEGIN  
           SET @myName = db_cursor.name;
           SET @myAge = db_cursor.age;
           SET @myFavoriteColor = db_cursor.favoriteColor;
           --Do stuff with scalar values

           FETCH NEXT FROM db_cursor; 
    END

Help is always appreciated.

This should work:

DECLARE db_cursor CURSOR FOR SELECT name, age, color FROM table; 
DECLARE @myName VARCHAR(256);
DECLARE @myAge INT;
DECLARE @myFavoriteColor VARCHAR(40);
OPEN db_cursor;
FETCH NEXT FROM db_cursor INTO @myName, @myAge, @myFavoriteColor;
WHILE @@FETCH_STATUS = 0  
BEGIN  

       --Do stuff with scalar values

       FETCH NEXT FROM db_cursor INTO @myName, @myAge, @myFavoriteColor;
END;
CLOSE db_cursor;
DEALLOCATE db_cursor;
