在 MariaDB 和 Python 中使用帶有變量的 Like 運算符

Question

在燒瓶中，我試過

with db.engine.connect() as connection
    query_str = "SELECT * FROM db_name WHERE name LIKE :condition"
    connection.execute(text(query_str), condition="%" + word + "%")

但它沒有用。 我該如何修復代碼？

import mysql.connector as mariadb
mariadb_connection = mariadb.connect()
cursor = mariadb_connection.cursor()
cursor.execute("SELECT * FROM db_name WHERE name LIKE %s", (some_name,))

問題是您在連接上調用 execute() 而不是該連接的游標。
