MySQL db调用:不是所有在字符串格式化期间转换的参数

Question

当我执行以下给定的代码时，我得到了错误not all arguments converted during string formatting：

pro_title = "FSBT"
print "pro_title: " + pro_title
pro_id_query = "SELECT ID FROM projs WHERE pro_title=%s"
cursor.execute(pro_id_query, pro_title)
db.commit()
row = cursor.fetchone()
pro_id = None
if row is not None:
   pro_id = str(row[0])    
print "pro_id: " + pro_id

我也试过format

pro_id_query = "SELECT ID FROM projs WHERE title={}"
cursor.execute(pro_id_query.format(pro_title))

只有当我在'中使用{}时，它才能工作。

pro_id_query = "SELECT ID FROM projs WHERE title='{}'"
cursor.execute(pro_id_query.format(pro_title))

我不明白为什么INSERT %s**，查询与查询有很好的关系，而** SELECT 查询没有：

insert_query = "INSERT INTO projs (title, description) VALUES (%s, %s) ON DUPLICATE KEY UPDATE `title`=%s"
cursor.execute(insert_query, (pro_title, pro_description, pro_title))

Answer 1

pro_title = "FSBI" 
pro_id_query = "SELECT * FROM %s"%(pro_title)
cursor = con.cursor() 
cursor.execute(q) 
result_list = result.fetchall()   
result_list[0][0] 
con.commit() 
con.close()

pro_id_query = cursor.fetchone() while row != False:
print ("The ID is : ", row[0])

*编辑

id = input("Id : ")
name = input("Name : ")
cursor = con.cursor()
cursor.execute(""" INSERT INTO names (id, name) VALUES("%s", "%s")"""
          %(id, name))
