Question

我有一个简单的tkinter应用程序，我建立了我工作的小时数。由于某种原因，我不断收到此错误＆＃34; DatabaseError：ORA-01036：非法变量名称/编号＆＃34;任何帮助将不胜感激！

这是我的SnowTime.py

import os 
import sys
import Tkinter
import tkMessageBox
import cx_Oracle 
from datetime import date, datetime, timedelta
import time


def insertBcl():
     connection = cx_Oracle.connect('user', 'password', cx_Oracle.makedsn('xxx.xxx.xxx.xxx', 'port', 'sid'))
     cursor = connection.cursor()
     cursor.execute("SELECT MAX(TRANSACTION_ID) FROM LABOR")
     for result in cursor:

         r = reduce(lambda rst, d: rst * 10 + d, (result))

         f = r + 1
     #cursor.close()
     #connection.close()


     hours = e1.get()
     today = datetime.now().date().strftime("%Y-%m-%d")

     SNOWJ = "SNOWJ"
     I = "I"
     OH = "OH"
     W = "W"
     null = "null"
     zero = 0
     N = "N"
     SNOW = "SNOW"



     add_time =("INSERT INTO TEST " 
                    "(EMPLOYEE_ID, TRANSACTION_DATE, TRANSACTION_ID, TYPE, INDIRECT_ID, HOURS_WORKED, GOOD_QTY, BAD_QTY, SHIFT_ID, SETUP_COMPLETED, PASS_FAIL, CREATE_DATE, REASON, USER_ID, OPEN_OP)"
                     "VALUES (%(EMPLOYEE_ID)s, %(TRANSACTION_DATE)s, %(TRANSACTION_ID)s, %(TYPE)s, %(INDIRECT_ID)s, %(HOURS_WORKED)s, %(GOOD_QTY)s, %(BAD_QTY)s, %(SHIFT_ID)s, %(SETUP_COMPLETED)s, %(PASS_FAIL)s, %(CREATE_DATE)s, %(REASON)s, %(USER_ID)s, %(OPEN_OP)s)")

     data_time = { 'EMPLOYEE_ID': SNOWJ,
                  'TRANSACTION_DATE': today, 
                  'TRANSACTION_ID': f,
                  'TYPE': I,
                  'INDIRECT_ID': OH,
                  'HOURS_WORKED': hours,
                  'GOOD_QTY': zero,
                  'BAD_QTY': zero,
                  'SHIFT_ID': null,
                  'SETUP_COMPLETED': N,
                  'PASS_FAIL': N,
                  'CREATE_DATE': today,
                  'REASON': null,
                  'USER_ID': SNOW,
                  'OPEN_OP': null,
    }    


     print add_time

     print data_time

     cursor.execute(add_time, data_time)

    connection.commit()
    cursor.close()  
    connection.close()

这是打印时add_time的样子

 INSERT INTO TEST (EMPLOYEE_ID, TRANSACTION_DATE, TRANSACTION_ID, TYPE, INDIRECT_ID, HOURS_WORKED, GOOD_QTY, BAD_QTY, SHIFT_ID, SETUP_COMPLETED, PASS_FAIL, CREATE_DATE, REASON, USER_ID, OPEN_OP)VALUES (%(EMPLOYEE_ID)s, %(TRANSACTION_DATE)s, %(TRANSACTION_ID)s, %(TYPE)s, %(INDIRECT_ID)s, %(HOURS_WORKED)s, %(GOOD_QTY)s, %(BAD_QTY)s, %(SHIFT_ID)s, %(SETUP_COMPLETED)s, %(PASS_FAIL)s, %(CREATE_DATE)s, %(REASON)s, %(USER_ID)s, %(OPEN_OP)s)

这是data_time看起来像print

{'CREATE_DATE': '2015-11-13', 'OPEN_OP': 'null', 'HOURS_WORKED': '4', 'REASON': 'null', 'TRANSACTION_DATE': '2015-11-13', 'INDIRECT_ID': 'OH', 'TRANSACTION_ID': 12816058, 'PASS_FAIL': 'N', 'USER_ID': 'SNOW', 'EMPLOYEE_ID': 'SNOWJ', 'SHIFT_ID': 'null', 'SETUP_COMPLETED': 'N', 'GOOD_QTY': 0, 'BAD_QTY': 0, 'TYPE': 'I'}

这是我的表结构

column_name                     data_type 

EMPLOYEE_ID                     VARCHAR2(15 BYTE)            
TRANSACTION_DATE                DATE               
TRANSACTION_ID                  NUMBER(10,0)          
TYPE                            CHAR(1 BYTE)           
INDIRECT_ID                     VARCHAR2(15 BYTE)              
HOURS_WORKED                    NUMBER(7,2)               
GOOD_QTY                        NUMBER(14,4)           
BAD_QTY                         NUMBER(14,4)        
SHIFT_ID                        VARCHAR2(15 BYTE)               
SETUP_COMPLETED                 CHAR(1 BYTE)            
PASS_FAIL                       CHAR(1 BYTE)         
CREATE_DATE                     DATE            
REASON                          VARCHAR2(50 BYTE)              
USER_ID                         VARCHAR2(15 BYTE)       
OPEN_OP                         CHAR(1 BYTE)

在Oracle中，当您使用保留关键字时会发生奇怪的事情。

我看到你有一个名为TYPE的表列，这是一个关键词。你可以尝试像这样的双引号技巧

 INSERT INTO TEST (EMPLOYEE_ID, TRANSACTION_DATE, TRANSACTION_ID, "TYPE", ... 

%(TYPE)s, %(INDIRECT_ID)s, %(HOURS_WORKED)s, %(GOOD_QTY)s, %(BAD_QTY)s, %(SHIFT_ID)s, %(SETUP_COMPLETED)s, %(PASS_FAIL)s, %(CREATE_DATE)s, %(REASON)s, %(USER_ID)s, %(OPEN_OP)s)

如果您仍然遇到奇怪的错误，我建议将列TYPE重命名为非关键词。
