Example 1: sql cursor example

DECLARE @name VARCHAR(50) -- database name 
DECLARE @path VARCHAR(256) -- path for backup files 
DECLARE @fileName VARCHAR(256) -- filename for backup 
DECLARE @fileDate VARCHAR(20) -- used for file name 

SET @path = 'C:\Backup\' 

SELECT @fileDate = CONVERT(VARCHAR(20),GETDATE(),112) 

DECLARE db_cursor CURSOR FOR 
SELECT name 
FROM MASTER.dbo.sysdatabases 
WHERE name NOT IN ('master','model','msdb','tempdb') 

OPEN db_cursor  
FETCH NEXT FROM db_cursor INTO @name  

WHILE @@FETCH_STATUS = 0  
BEGIN  
      SET @fileName = @path + @name + '_' + @fileDate + '.BAK' 
      BACKUP DATABASE @name TO DISK = @fileName 

      FETCH NEXT FROM db_cursor INTO @name

        list_price
    FROM 
        production.products;

OPEN cursor_product;

FETCH NEXT FROM cursor_product INTO 
    @product_name, 
    @list_price;

WHILE @@FETCH_STATUS = 0
    BEGIN
        PRINT @product_name + CAST(@list_price AS varchar);
        FETCH NEXT FROM cursor_product INTO 
            @product_name, 
            @list_price;
    END;

CLOSE cursor_product;

DEALLOCATE cursor_product;
