使用where var like语句导入sqlite3

Question

我有这段代码：

Title= "somewords"
itemID = somenumbers
import sqlite3
db = sqlite3.connect('C:\\db.sqlite')
cursor = db.cursor()
cursor.execute('SELECT itemID FROM itemAttachments WHERE path LIKE "%?%"  ', (Title, ))
cursor.execute('SELECT key FROM items WHERE itemID =? ', (itemID,))

where item=?的第二个陈述有效，但第一个有like的陈述给我带来了麻烦。

我尝试了许多组合，例如"+Title+"和{} .format(Title)，添加或删除＆＃34; %...%"，但每次收到错误：sqlite3.ProgrammingError: Incorrect number of bindings supplied或sqlite3.OperationalError: near ",": syntax error。

Answer 1

您必须将%添加到参数：

cursor.execute('SELECT itemID FROM itemAttachments WHERE path LIKE ?', ('%{}%'.format(Title), ))
