我有多个值,如下所示:
1.212302157,305027504,302002744
2.305027504,302002744,212302157
我想删除212302157并添加212605226。
同一行的单行更新查询是什么。
答案 0 :(得分:0)
我认为这不是最好的方式.. 但我对这个问题的回答是
语法:
from kivy.lang import Builder
from kivy.uix.boxlayout import BoxLayout
from kivy.app import App
from kivy.properties import StringProperty
kv_text = '''
#simplekivy.kv
<Page>:
img: '' #<<<<<<<<<<<<<<<<<<
canvas.before:
Color:
rgba:0,0,1,1
Rectangle:
pos: self.pos
size: self.size
Image:
pos_hint:{"center_x":0.4,"y":0.3}
color:255,1,1,1
size:70,70
source: root.img
Label:
pos:0,0
font_size:80
text:root.id1
Button:
size_hint:0.5,0.2
font_size:60
text:"Start"
on_press: app.onClick()
'''
class Page(BoxLayout):
id1=StringProperty()
def __init__(self):
super(Page, self).__init__()
self.id1="ellow"
self.img="logo.jpg"
class SimpleKivyApp(App):
def build(self):
Builder.load_string(kv_text)
return Page()
if __name__ == '__main__':
SimpleKivyApp().run()
根据我的询问:
update Table_name set c_name = concat(
Replace(
Replace( c_name, concat('RemovedStr',','), '' ),
concat(',' ,'RemovedStr'), ''
),
'AddedStr'
) [where condition];
