cx_Oracle:错误933. ORA-00933:“SQL命令未正确结束”:SQL命令错误?
问题描述:
以前也有类似的问题,但我仍然无法找到解决方案。我的代码:cx_Oracle:错误933. ORA-00933:“SQL命令未正确结束”:SQL命令错误?
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
的find_command
看起来是这样的:
SELECT * FROM myTable WHERE msgid_i = 2R67C865FB6ZHG5A9
我试过有和没有在SQL查询的末尾分号,但仍然失败。我知道连接的工作原理,因为我有另一个查询(见下文),并将数据写入表中。只是当试图查找包含某些值的行时,我是否会收到此错误消息。
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。
答
正如评论上面提到的,使用的参数如下所示:
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)
+0
这就是我正在寻找的,thx。 – pymat
+0
不客气。那么你能将答案标记为接受吗?谢谢! –
使用的参数,而不是直接把字符串值。实际上,你需要围绕字符串常量使用单引号。 –
@GordonLinoff你的意思是find_command应该类似于上面的插入命令? – pymat
你可以使用这个我猜''如果你不太在意SELECT * FROM myTable WHERE msgid_i = \'{0} \'“',但是你应该使用参数化查询。 –
