Question

我正在尝试搜索像变量这样的数据，但我想查找像％？％这样的数据，但是这当然不起作用，我可以使用LIKE吗？但我还需要找到所有值，例如D并附带Dog

       search=self.text
    with sqlite3.connect('Data.db') as db:
        user_find = db.cursor()
        user_find.execute(
            'select * from "Animal Data" where Animal_ID LIKE ? or Animal_Name LIKE ? or Animal_Type LIKE ? or Animal_Gender LIKE ? or Animal_breed LIKE ? or Animal_breed LIKE ? or Animal_breed LIKE? or Animal_colour LIKE ? or Address LIKE ?'
            ,(search,search,search,search,search,search,search,search,search,))
        data = user_find.fetchall()
        print(data)

您应该将要显示在?语句中的整个表达式绑定到LIKE占位符。也就是说，如果您要搜索具有字母D的任何字段，则可以将字符串%D%绑定到语句。

search = '%' + search + '%'
user_find = db.cursor()
user_find.execute(
    'select * from "Animal Data" where Animal_ID LIKE ? or Animal_Name LIKE ? or Animal_Type LIKE ? or Animal_Gender LIKE ? or Animal_breed LIKE ? or Animal_breed LIKE ? or Animal_breed LIKE? or Animal_colour LIKE ? or Address LIKE ?',
    (search,search,search,search,search,search,search,search,search,)
)
data = user_find.fetchall()
print(data)

搜索数据就像一个变量，但我想找到像％？％这样的数据，但是这当然行不通
