Python 得到错误 cx_Oracle.DatabaseError： ORA01008： not all variables bound while trying to bind the value of a list in a merge statement

在过go 的几个小时里，我一直在头痛，但找不到根本原因.浏览了多篇文章，但运气不佳.

我正在try 合并存储在Pandas 数据框中的值.

merchantinfo_lst = appenddata.values.tolist()

通过下面的代码，我试图将数据合并到目标表中.

sql ='merge into bi.merchant_info_test ';
sql+=' using dual';
sql+='   on ( ATRANS_ID = :2 )';
sql+=' when matched then update set MERCHANT_INFO = :15, MESSAGE_PARAM = :16, PUBLISH_DATE = :13' ;  
sql+=' when not matched then insert( ADDRESS,ATRANS_ID,CITY_NAME,COUNTRY_CODE,LATITUDE,LONGITUDE,MERCHANT_CATEGORY_CODE,MERCHANT_DESCRIPTOR,MERCHANT_ID,';
sql+=' MERCHANT_NAME,PHONE_NUMBER,POSTAL_CODE,PUBLISH_DATE,STATE_PROVINCE_CODE,MERCHANT_INFO,MESSAGE_PARAM )'; 
sql+='  values( :1, :2, :3,:4,:5,:6,:7,:8,:9,:10,:11,:12,:13,:14,:15,:16 )';
for i in range(len(merchantinfo_lst)):
    cur.execute(sql,merchantinfo_lst[i])

我正在获取cx\U Oracle.DatabaseError:ORA-01008:并非所有变量都已绑定，但列表中存在所有值，目标表中存在所有列.

Python版本:2.7.5
