ORA-01036: 非法变量名称/编号 (cx_Oracle)

Question

当我尝试将数据插入数据库时​​，当我使用以下代码时，我可以看到上述错误。

您能否建议您还可以做什么。

代码：

list_to_add=['Have you searched','similar question has already been posted']

dsn_tns = cx.makedsn(cred_test['HOST'], cred_test['PORT'], service_name=cred_test['SERVICE_NAME'])

conn = cx.connect(user=cred_test['USER'], password=cred_test['PASWRD'], dsn=dsn_tns)

cursor = conn.cursor()

cursor.prepare('INSERT INTO Table_name Col_name values (:0)')

cursor.executemany(None,list_to_add)

conn.commit()

Answer 1

你有一些小问题：

1. ORA-01036由于列表元素未用方括号括起来而引发

2. ORA-00947 将在解决第一个问题后引发，因为 Col_name 在 Insert 语句中没有用括号括起来

   list_to_add=[['Have you searched'],['similar question has already been posted']]
   
   dsn_tns = cx.makedsn(cred_test['HOST'], cred_test['PORT'], service_name=cred_test['SERVICE_NAME'])
   
   conn = cx.connect(user=cred_test['USER'], password=cred_test['PASWRD'], dsn=dsn_tns)
   
   cursor = conn.cursor()
   
   cursor.prepare('INSERT INTO Table_name(Col_name) VALUES(:0)')
   
   cursor.executemany(None,list_to_add)
   
   conn.commit()
