标签: mysql-python

我知道这已被问过几次了,但经过几个小时的尝试,没有办法让这个工作.

我已经从dmg文件和MySQL-python-1.2.3安装了MySQL 32位.

我按照这个步骤操作,但是当我运行时python setup.py build,会出现这些错误:

我试图安装MySQL-python包有以下错误:

cc1: error: unrecognized command line option "-arch"
cc1: error: unrecognized command line option "-Wno-long-double"
error: Setup script exited with error: command 'gcc' failed with exit status 1

我正在使用Mac OSX version 10.6.8gcc

bash-3.2$ gcc --version
gcc (GCC) 4.2.1 (Apple Inc. build 5666) (dot 3)  

我该如何解决这个问题？

谢谢

我正在尝试设置Django以使用MySQL.当我输入时,我收到以下错误localhost/mysite

ExtractionError at /
Can't extract file(s) to egg cache

The following error occurred while trying to extract file(s) to the Python egg
cache:

  [Errno 13] Permission denied: '/Library/WebServer/.python-eggs'

The Python egg cache directory is currently set to:

  /Library/WebServer/.python-eggs

Perhaps your account does not have write access to this directory?  You can
change the cache directory by setting the PYTHON_EGG_CACHE environment
variable to point to an accessible directory.

从错误消息我知道我必须更改PYTHON_EGG_CACHE环境变量以指向Apache可以访问的目录.我尝试添加以下内容httpd.conf

SetEnv PYTHON_EGG_CACHE /var/www
<Directory /var/www>

我在MySQLdb上使用xampp和python.我正在连接然后运行:

cursor.execute("INSERT INTO customer SET name='aaa'")

不会引发任何错误,但没有向数据库添加任何行(与pypmyadmin一起检查).但是,该表正在递增其自动增量字段.

发生了什么,我该如何阻止它？

我试图从数据库中获取一个值pymysql.我目前的解决方案是3行代码.这是处理这个问题的最佳方法吗？

import pymysql

conn = pymysql.connect(host='localhost', user='root', passwd='')
conn.autocommit(True)
cur = conn.cursor()

memory = '100'

# I want to access one item from mySQL
cur.execute("""SELECT id FROM scada.sensors WHERE memory='{}'""".format(memory))
for x in cur.fetchall(): # only runs once
   sensor_id=x[0]

我需要这个for循环来访问内容cur.fetchall()吗？

我使用的是Python 3.2.3

我想在运行此代码时通过python.But简单地访问mysql数据库:

import MySQLdb
db = MySQLdb.connect(host = "127.0.0.1",
                     port = "3306",
                      user="Bishnu",
                      passwd = "Pulchowk",
                      db = "student")
cursor =db.cursor()
cursor.execute("select * from basic_info")
numrows = int(cursor.rowcount)
for x in range(0,numrows):
    row = cursor.fetchall()
    print row[0],"-->",row[1]
db.cose()

它给出了一个错误:

Traceback (most recent call last):
  File "C:\Users\Bishnu\Desktop\database", line 6, in <module>
    db = "student")
  File "C:\Python27\lib\site-packages\MySQLdb\__init__.py", line 81, in Connect
    return Connection(*args, **kwargs)
  File "C:\Python27\lib\site-packages\MySQLdb\connections.py", line 187, in __init__
    super(Connection, self).__init__(*args, **kwargs2)
TypeError: an integer is required

那是什么TypeError:需要一个整数

为什么会出现这种问题 要运行此代码我有3个问题,但幸运的是这个论坛解决了我的两个问题,我认为它也将解决？

像许多人一样,我遇到了让mysql和python一起工作的问题.我的规格是:

OSX10.9.2带有python 2.7.2的Anaconda 1.9.1,虽然2.5和2.6似乎包含在MySQL 5.6.16中

我写了一个python脚本,我尝试导入MySQLdb,或PyMySQL然后MySQLdb,都没有工作.

我读了很多关于堆栈溢出的线程,结果我最终尝试了

$ export CFLAGS=-Qunused-arguments
$ export CPPFLAGS=-Qunused-arguments
$ pip install mysql-python

结果如下.发出致命错误,可以在输出的底部看到.

我试图通过python脚本运行MySQL查询并继续在我的SQL语法中出错,从我可以看到查询设置正确.有人可以给我第二眼吗？

    conn = mysql.connector.connect(**config)
    connect = conn.cursor()
    query = u'INSERT INTO page_load_times (self, object_id, page_header, elapsed_time, date_run) ' \
            'VALUES ({}, {}, {}, {}, {})'.format(self, self.object_id, self.page_header, t.interval, timestamp)
    connect.execute(query)
    conn.commit()
    conn.close()

我得到的错误如下:

ProgrammingError: 1064 (42000): You have an error in your SQL syntax; 
check the manual that corresponds to your MySQL server version for the right 
syntax to use near '13:56:17.491000)' at line 1

我在下面的代码中删除了日期列值为current_date的表中的所有行。

db = MySQLdb.connect("localhost",'root','XXXX','XXXX')
cur = db.cursor()
query = "delete from RealTimeData where date = current_date()"
cur.execute(query)
db.commit()

现在，我怎么知道我的查询从表中删除了多少行？我尝试过fetchone()回来None

我最近升级到Mac OS Mojave，现在无法安装MySQL-Python：

pip install MySQL-Python

堆栈跟踪显示未找到“ ssl”库。我不确定这是什么意思，因为我已经安装了最新的XCode和OpenSSL。任何建议表示赞赏。
