python - ValueError 不支持的格式字符 'd' 与 psycopg2

Question

我有这样的代码:

print "company_id = %d" % company_id
...
db.cursor.execute("insert into person (company_id, first, last, type) values (%d, '%s', '%s', %d);", (company_id, name[0], name[1], type))

我得到以下输出:

company_id = 1
Traceback (most recent call last):
...
  File "./GetPeople.py", line 125, in insertPerson
    db.cursor.execute("insert into person (company_id, first, last, type) values (%d, '%s', '%s', %d);",     

为什么它可以打印出第一行，但在调用 db.cursor.execute() 时却报错？

Answer 1

%s 占位符周围的单引号不正确且未使用 %d as per the docs .变化

db.cursor.execute("insert into person (company_id, first, last, type) values (%d, '%s', '%s', %d);", (company_id, name[0], name[1], type))

到

db.cursor.execute("insert into person (company_id, first, last, type) values (%s, %s, %s, %s);", (company_id, name[0], name[1], type))
