我需要一些关于代码的帮助，我使用代码写入数据以在数据库中输入数据，我将数据从与其他数据相同的行向下移动。
示例：
================================================================
name | start_date | stop_date | program_id | programme_title |
================================================================
channel 1 3001 some name 1
channel 1 3002 some name 2
channel 1 3003 some name 3
以下是将program_id移动到下一行的内容：
================================================================
name | start_date | stop_date | program_id | programme_title |
================================================================
channel 1 some name 1
channel 1 3001 some name 2
channel 1 3002 some name 3
这是我使用的代码：
def update_in_database(self):
profilePath = xbmc.translatePath(os.path.join('special://userdata/addon_data/script.tvguide', 'source.db'))
conn = database.connect(profilePath)
cur = conn.cursor()
program_id = ''.join(str(x) for x in self.program_id)
cur.execute('SELECT channel, program_id FROM programs')
data = cur.fetchone()
if data is not None:
value = program_id
for i in range(0,10):
if value == program_id:
cur.execute("UPDATE programs set program_id=? WHERE program_id=?",('',value))
else:
cur.execute("UPDATE programs set program_id=? WHERE program_id=?",(value-1,value))
value = int(value) + 1
cur.execute("SELECT channel , stop_date FROM programs WHERE program_id=?;",(value-2,))
data = cur.fetchone()
try:
cur.execute("UPDATE programs set program_id=? WHERE channel=? and start_date=? ",(value-1,data[0],data[1]))
except:
pass
conn.commit()
conn.close()
我想知道如何将数据移动到与我使用的代码相反的方向，因为我想要移动数据？
示例：
================================================================
name | start_date | stop_date | program_id | programme_title |
================================================================
channel 1 some name 1
channel 1 3001 some name 2
channel 1 3002 some name 3
以下是将program_id移动到下一行的内容：
================================================================
name | start_date | stop_date | program_id | programme_title |
================================================================
channel 1 3001 some name 1
channel 1 3002 some name 2
channel 1 3003 some name 3
你知道我怎么做吗？
