python - 在python中转义mysql语句时遇到问题

Question

我将如何在以下内容中转义 %：

cursor.execute('''SELECT MIN(id) FROM title WHERE provider=%s 
                  AND vendor_id LIKE "%s%"''', (provider, vendor_id_stem))

Answer 1

cursor.execute("SELECT MIN(id) FROM title WHERE provider=%s"
               "AND vendor_id LIKE '%s%%'", (provider, vendor_id_stem))

Answer 2

将其添加为 python 变量：

cursor.execute("SELECT MIN(id) FROM title WHERE provider=%s AND 
                vendor_id LIKE %s", (provider, vendor_id_stem + '%'))
