将数据从SQL server数据库移动到oracle数据库的Python脚本不断给出“ORA-01036:非法变量名称/编号”

因此，我使用python从sql server中提取数据，并使用一个简单的选择来获取15列。数据如下所示

2016-06-01 05:45:06.003,5270,240,1,1,0,5000,1,null,null,7801009661561,0,null,null,null

try:
    cnn = cx_Oracle.connect(user="####", password = "####", dsn = "####")
    trgtcrsr = cnn.cursor()
    print "Connected to Oracle"
except Exception as e:
    print e
    raise RuntimeError("Could not connect to Oracle")

oracle表上的列都是数字，但第一列是日期。尺寸都正确

获取所有数据后，我通过这个小函数运行它，以摆脱pyodbc.row类型

def BuildBindList(recordsToWrite):
    closingRecords = []
    for rec in recordsToWrite:
        closingRecords.append((rec[0], rec[1], rec[2], rec[3], rec[4],  rec[5], rec[6], rec[7], rec[7], rec[8], rec[9], rec[10], rec[11], rec[12], rec[13], rec[14]))
    return closingRecords    

我得到一个元组列表

然后为了写入oracle表，我编写了这个函数，它接受元组列表

    def write_to_table(recordsToWrite):     
        SQL = '''INSERT INTO ####### (DATETIME, ID, TZ, DOMAINID, EVENTNAME, REASONCODE, TARGETID, STATE, KEY, PERIPHERALKEY, RECOVERYKEY, DIRECTION, ROUTERDAY, ROUTERCKEY, ROUTERNUMBER)
                VALUES(:1, :2, :3, :4, :5, :6, :7, :8, :9, :10, :11, :12, :13, :14, :15)'''
        try:
            trgtcrsr.prepare(SQL)
        except cx_Oracle.DatabaseError, exception:
            print ('Failed to prepare cursor')
            print Exception(exception)
            exit (1)
        try:
            trgtcrsr.executemany(None, recordsToWrite)        
        except cx_Oracle.DatabaseError, exception:
            print ('Failed to insert rows')
            print Exception(exception)
            exit (1)
        target_connection .commit()
        target_connection .close()            

我这样做oracle连接

2016-06-01 05:45:06.003,5270,240,1,1,0,5000,1,null,null,7801009661561,0,null,null,null

try:
    cnn = cx_Oracle.connect(user="####", password = "####", dsn = "####")
    trgtcrsr = cnn.cursor()
    print "Connected to Oracle"
except Exception as e:
    print e
    raise RuntimeError("Could not connect to Oracle")

连接工作正常。但是，当执行行trgtcrsr.executemanyNone、recordsToWrite时，会出现“ORA-01036:非法变量名/编号”错误

我有另一个脚本，它使用与trgtcrsr.prepareSQL/trgtcrsr.executemanyNone、recordsToWrite方法相同的方法将元组列表写入oracle表，并且它工作正常，允许oracle向oracle写入，因此我不确定为什么会不断出现此错误。我尝试过改变数据类型并用谷歌搜索错误，但找不到类似的结果

有什么想法吗？

rec[7]在函数BuildBindList中出现两次

我猜这会导致insert失败，因为您在insert语句中传递了16列来实例化15个bind变量。

无法插入的记录值是什么？@Daniel它没有告诉我。@bernie不是元组列表还是元组容器？@JohnGordon您说得很对。但是表名包含我没有包含的标识信息，这就是为什么在绑定列表中两次获得you have rec[7]的原因。。可能是列数不匹配。我觉得自己太傻了，没注意到这一点。非常感谢，这解决了问题。
