同事在使用python3操作sqlite时出现了异常，具体代码缩减如下： import sqlite3 conn = sqlite3.connect('star.db') cursor = conn.cursor() insert_sql = 'insert into user(id,name) values (%s,%s)' cursor.execute(insert_sql,(1,'小麦')) 一看错误提示就是语法错误，还在%附近，笔者之前写过一篇python3操作数据库的文章中，提到过，sqlite的占位符请使用？，重要的事情就不说三遍了。获取更多知识，可以关注我的公众号：码农小麦

This error message indicates that there is a unique constraint applied to the "内容" field in the "Content" table of your SQLite database, and that constraint has been violated. A unique constraint ensures that no two rows in a table have the same value in a particular column. In this case, it seems that you are trying to insert a row with a value in the "内容" field that already exists in another row, and this violates the unique constraint. To resolve this issue, you need to either remove the unique constraint from the "内容" field or ensure that the value you are trying to insert is unique. You can also update the existing row with the same value instead of inserting a new one.
