DECLARE #fileName VARCHAR(256) -- filename for backup
DECLARE #fileDate VARCHAR(20) -- used for file name
-- specify database backup directory location
SET #path = 'D:\Backup\'
-- specify filename format
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
