我有以下字典:
{ '': ['0', '9'],
'3904': ['playback_error', '87'],
'3808': ['playback_error', '24'],
'3902': ['qp_library_failed_to_start', '1'],
'3903': ['playback_error', '464'],
'3805': ['playback_error', '141'],
'3807': ['playback_error', '29'],
'3806': ['playback_error', '1'],
'1309': ['playback_error', '2'],
'3803': ['playback_error', '28'],
'BL-1008': ['parental_controls_error', '5'],
'errorCode': ['eventKey', '2'],
'404': ['tbr_error', '68'],
'3308': ['playback_error', '10']}
我想将这些值插入到mysql数据库中,例如:
ERRORCODE, EVENTKEY, COUNT
3904, playback_error, 87
3808,playback_error, 24
3902,qp_library_failed_to_start,1
3903,playback_error
我创建了一个python代码来执行此操作,但它不会将值插入数据库 我收到错误:mysql_exceptions.OperationalError:(1136,"列数不匹配第1行和第34行的值计数;) 这是我的python代码:
data=mydict
print data
#print data.values()
# Open database connection
db = MySQLdb.connect(host,user,passwd,db)
cursor = db.cursor()
# Prepare SQL query to INSERT a record into the database.
sql = '''INSERT INTO errorscode (id,date,errorcode,eventkey,count) VALUES(NULL,(DATE_ADD(CURDATE(), INTERVAL -1 day),%s,%s,%s))'''
# Execute the SQL command
cursor.executemany(sql,data.values())
# Commit your changes in the database
db.commit()
# disconnect from server
cursor.close()
db.close()
感谢下面的答案,我解决了我的问题最终代码工作100%:):
#!/usr/bin/python
from StringIO import StringIO
import numpy as np
import csv
import MySQLdb
import os
with open('csv_err2.log', mode='r') as infile:
reader = csv.reader(infile)
mydict = dict((rows[0],[rows[2], rows[1]]) for rows in reader)
data=mydict
print data
# Open database connection
db = MySQLdb.connect(host="localhost",user="root",passwd="bravoecholimalima",db="capacityreports_mobiletv")
cursor = db.cursor()
# Prepare SQL query to INSERT a record into the database.
sql = '''INSERT INTO errorscode (id,date,errorcode,count,eventkey) VALUES(NULL,(DATE_ADD(CURDATE(), INTERVAL -1 day)),%s,$
sql_values_list = list()
for key, value in data.iteritems():
sql_values_list.append((key,int(value[0]),value[1]))
print sql_values_list
# Execute the SQL command
cursor.executemany(sql, sql_values_list)
# Commit your changes in the database
db.commit()
# disconnect from server
cursor.close()
db.close()
答案 0 :(得分:1)
嗯,这种方法不起作用。
对于其中一个,您的案例中的mydict.values()
或data.values()
将是一个列表列表:
[[' 0',' 9'],[' playback_error',' 87'],[' playback_error& #39;,' 24'], [' qp_library_failed_to_start',' 1'],[' parental_controls_error',' 5'], [' playback_error',' 141'],[' playback_error',' 29'], [' playback_error',' 1'],[' playback_error',' 2'],[' playback_error', ' 28'],[' eventKey',' 2'],[' playback_error',' 10'], [' playback_error&#39 ;, ' 464'],[' tbr_error',' 68']]
所以,如果你想迭代,你需要的东西是:
sql = '''INSERT INTO errorscode (id,date,errorcode,eventkey,count) VALUES(NULL,(DATE_ADD(CURDATE(), INTERVAL -1 day),%s,%s,%s))'''
sql_values_list = list()
for key, value in data.iteritems():
sql_values_list.append((key, value[0], value[1]))
try:
# Execute the SQL command
cursor.executemany(sql, sql_values_list)
# Commit your changes in the database
db.commit()
except:
# bla
data.iteritems()
将在迭代期间一次性检索密钥和相应的值,您可以进一步使用。您的价值是一个列表,这就是为什么要将其传递给您,您需要明确地解决这些成员问题。
您将dict重组为.executemany()
的格式并将其传递。
请注意,如果您的数据结构不是静态的,那么我在示例中显示的方式可能不安全,即如果您有一个值,其中list只包含1个元素 - 代码将失败。
