参数化插入 Python pymysql

Question

我有以下代码块

def write_metadata(self):
    try:
        with self.sql_writer.cursor as cursor:
            for data in self.input_data:
                sql = ("""INSERT INTO Sample (SampleName, TransferStatus, ClientSid, ClientSubjectId, ClientName, ProjectId, ProjectName, ExecutionId, Deleted)
                    VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s""")
                package_data = (data.sample_name, 0, 'client_sid', "Testing", data.client_name, data.project_id, data.project_name, '12345', '0')
                cursor.execute(sql, package_data)
            self.sql_writer.conn.commit()
    finally:
       self.sql_writer.conn.close()

我遇到的错误是

"errorMessage": "(1064, u\"You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1\")"

我对 sql 的参数设置有问题吗？问题是因为某些值是数字而 %s 是字符串吗？问题是因为某些值是 None?

谢谢。

Answer 1

您的 VALUES().

末尾缺少闭括号 )

您还错误地使用了多行字符串。试试这个：

sql = """INSERT INTO Sample (SampleName, TransferStatus, ClientSid, ClientSubjectId, ClientName, ProjectId, ProjectName, ExecutionId, Deleted)
          VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s)"""
