Question

对不起，如果这是重复的话;我尝试搜索Google和之前的Stack Overflow问题，但无法找到答案。

连接代码：

import cx_Oracle as o
con = o.connect('**', '**', '**')
con.version
cur = con.cursor()

加载DF的代码：

import pandas as pd
df = pd.read_excel("filename.xlsx")

df有两列，COLUMN1为7位数字，COLUMN2为字符串

我有一个名为＆＃39; MARSHALLTEST＆＃39;的Oracle表。使用COLUMN1 number(7)和COLUMN2 varchar(200)，我希望INSERT INTO该表中的相应列。

这给了我一条错误消息：

rows = [tuple(x) for x in df.values]
cur.executemany('''INSERT INTO MARSHALLTEST (COLUMN1, COLUMN2) VALUES (:0,:1)''',rows)
con.commit()

错误讯息：

---------------------------------------------------------------------------
UnicodeEncodeError                        Traceback (most recent call last)
<ipython-input-6-c4f7ad8118fd> in <module>()
      1 #statement = 'insert into MARSHALLTEST (OPPORTUNITY_INVOICE) values (df1)'
      2 rows = [tuple(x) for x in df.values]
----> 3 cur.executemany('''INSERT INTO MARSHALLTEST ('OPPORTUNITY_INVOICE', 'SF_OPP_ID') VALUES (:0,:1)''',rows)
      4 con.commit()

UnicodeEncodeError: 'ascii' codec can't encode character '\u201a' in position 22: ordinal not in range(128)

我也试过这个：

for s in df:
    statement = 'insert into MARSHALLTEST (OPPORTUNITY_INVOICE, SF_OPP_ID) values (s)' 
    cur.execute(statement)
    con.commit()

错误讯息：

DatabaseError                             Traceback (most recent call last)
<ipython-input-15-2c2e69dfd9bf> in <module>()
      1 for s in df:
      2         statement = 'insert into MARSHALLTEST (OPPORTUNITY_INVOICE, SF_OPP_ID) values (s)'
----> 3         cur.execute(statement)
      4         con.commit()

DatabaseError: ORA-00947: not enough values

您可以使用以下代码将数据框直接保存到表中：导入cx_Oracle

从sqlalchemy导入类型，create_engine

newconn = create_engine（'oracle + cx_oracle：// username：pswd @ host：port /？service_name = xxx'）

df.to_sql（'testtablex'，newconn，if_exists ='replace'，index = False）

使用python插入oracle表列
