cx_Oracle：错误 933。ORA-00933：“SQL 命令未正确结束”：SQL 命令错误？

Question

以前也有人问过类似的问题，但我仍然无法找到解决方案。我的代码：

    try:
        connection = cx_Oracle.connect(ORACLE_CONNECT)
        logger.info("Connection to Oracle success.")
        print ("Oracle DB version: " + connection.version)
        print ("Oracle client encoding: " + connection.encoding)
        print ("Python version: " + platform.python_version())
    except cx_Oracle.DatabaseError as e:
        error, = e.args
        if error.code == 1017:
            print ("Username/password invalid.")
            logger.debug("Username/password invalid: %s", error.code)
        else:
            logger.debug("Database connection error: %s", e)
            print ("Database connection error: %s".format(e))
        raise

    cursor = connection.cursor()
    smsreport_text_new = tuple(smsreport_text)
    find_command = self.identify_unique_msgid(smsreport_list)
    cursor.execute(find_command)

 def identify_unique_msgid(self, smsreport_list):
    msgid_i_to_be_crosschecked = smsreport_list.get('msgid_i')
    msgid_ii_to_be_crosschecked = smsreport_list.get('msgid_ii')
    find_command = 'SELECT * FROM myTable WHERE msgid_i = {0}'.format(msgid_i_to_be_crosschecked)
    print (find_command)

    return find_command

find_command 看起来像这样：

SELECT * FROM myTable WHERE msgid_i = 2R67C865FB6ZHG5A9

我试过在 SQL 查询末尾使用和不使用分号，但仍然失败。我知道连接有效，因为我有另一个查询（见下文）并将数据写入 table。只是在尝试查找包含某些值的行时，我收到此错误消息。

insert into xura_push (date_sms, result_sms, msgid, msgparts, msgid_i, msgid_ii) values (TO_DATE(:1, 'dd-mon-yyyy hh24:mi:ss'), :2, :3, :4, :5, :6)

我哪里错了？

干杯，pymat。

如上评论所述，使用参数如下：

def identify_unique_msgid(self, smsreport_list):
    msgid_i_to_be_crosschecked = smsreport_list.get('msgid_i')
    msgid_ii_to_be_crosschecked = smsreport_list.get('msgid_ii')
    find_command = 'SELECT * FROM myTable WHERE msgid_i = :msgid'
    return find_command, dict(msgid = msgid_i_to_be_crosschecked)

cursor = connection.cursor()
smsreport_text_new = tuple(smsreport_text)
find_command, args = self.identify_unique_msgid(smsreport_list)
cursor.execute(find_command, args)
