SQL 简单到荒谬的语法错误 sql？

Question

通话中：

INSERT IGNORE INTO standard_group (group_name, subject, grade, country, state) VALUES (%(group_name), %(subject), %(grade), %(country), %(state));

与

('Arizona Social Studies Standards', 'Social Studies', '1', 'United States', 'AZ')

例如：

    print group_columns
    print group_sql
    print group
    cur.execute(group_sql, dict(zip(group_columns, group)))

但我总是得到：

['group_name', 'subject', 'standard_category', 'standard_sub_category', 'standard_name', 'standard_description', 'grade', 'country', 'state', 'is_common_core', 'is_state_standard']
INSERT IGNORE INTO standard_group (group_name, subject, grade, country, state) VALUES (%(group_name), %(subject), %(grade), %(country), %(state));
('Arizona Social Studies Standards', 'Social Studies', '1', 'United States', 'AZ')
Traceback (most recent call last):

我已经尝试使用命名参数 ? 和 %s，并得到

未使用所有参数
命名参数的参数数量错误
SQL语法

这是怎么回事？？我错过了什么？？？

Answer 1

看起来像是一个小错字。您忘记将 s 添加到参数

INSERT IGNORE INTO standard_group (group_name, subject, grade, country, state) VALUES (%(group_name)s, %(subject)s, %(grade)s, %(country)s, %(state)s);
