python mysql插入数据报错：TypeError: %d format: a number is required, not str

Navicat连接mysql出现2003——can't connect to mysql server on localhost(10061)

mysql 数据库导入导出方法总结（是时候总结）

1：起因

最近工作需求 ---- 实时统计一份数据，insert到mysql数据库中； 

方法：很自然的就想到了python插入数据库，yum install MySQL-python.x86_64à import MySQLdb(python2.X仅仅适用)

报错如下

" File"/usr/lib/pymodules/python2.6/MySQLdb/cursors.py", line 151, inexecute query = query % db.literal(args)

TypeError: %d format: a number is required, not str"

解决方案：The format string is not really a normal Python format string. Youmust always use %s for all fields. 也就是MySQLdb的字符串格式化不是标准的python的字符串格式化,应当一直使用%s用于字符串格式化

2，具体细节

（1）MySQLdb python包安装：

[@10.134.105.160 auto_tarh]#yum list | grep -i sql   ----
MySQL-python.x86_64                      1.2.3-0.3.c1.1.el6   @rhel-6.stable-rhel-x86_64-server-6  

-----yum install MySQL-python.x86_64 --> import MySQLdb(python2.X仅仅适用)

(2) mysql数据库安装

[@10.134.105.160 auto_tarh]#yum list installed | grep sql    ---- 检查安装列表

mysql.x86_64                   5.1.61-1.el6_2.1        @rhel-6.2-rhel-x86_64-server-6    ----- mysql –h192.168.0.1 –uusername -ppassword

mysql-devel.x86_64             5.1.61-1.el6_2.1        @rhel-6.2-rhel-x86_64-server-6

mysql-libs.x86_64              5.1.61-1.el6_2.1        @rhel-x86_64-server-6/6.2

php-mysql.x86_64               5.3.3-3.el6_2.8         @rhel-6.2-rhel-x86_64-server-6

----- yum installmysql.x86_64, 安装mysql命令

3，开始书写代码

（1）python insert代码

	cursor.execute("""
                    insert into tree (id,parent_id,level,description,code,start,end)
                    values (%d,%d,%d,%s,%s,%f,%f)
                    """, (1,1,1,'abc','def',1,1)
                    )

   （2）The structure of my MYSQL table is:
	id int(255),
	parent_id int(255),
	level int(11),
	description varchar(255),
	code varchar(255),
	start decimal(25,4),
	end decimal(25,4)

（3）遇到的错误：

" File"/usr/lib/pymodules/python2.6/MySQLdb/cursors.py", line 151, inexecute query = query % db.literal(args)

TypeError: %d format: a number is required, not str"

解决方案:The format string is not really a normal Python format string. Youmust always use %s for all fields. 也就是MySQLdb的字符串格式化不是标准的python的字符串格式化,

应当一直使用%s用于字符串格式化

（4）同时还遇到一个奇葩的错误：

_mysql_exceptions.ProgrammingError: (1064, "You havean error in your SQ L syntax; check the manual that

corresponds to your MySQLserver version for the right syntax to use near ')' at line 1")

  5 import MySQLdb            
  6                           
  7 conn= MySQLdb.connect(
  8         host='res.searchapp.rds.sogou',
  9         port = 3306,
 10         user='searchapp',
 11         passwd='searchappres',
 12         db ='searchapp',
 13         )
 14 cur = conn.cursor()
 15 def test():
 16 #插入一条数据
 17 #sqli="""insert into novel_card values('test3', 100, 1, 0.01, '20170707')"""
 18 #sqli="""insert into novel_card values('%s', %d, 1, 0.01, '20170707')"""
 19 
 20 #cur.execute(sqli)
 21 #sqli="""insert into novel_card values('%s', '%s', '%s', '%s', '%s')"""
 22 #sqli="""insert into novel_card (runoob_author, show, click, ctr, data_time) values('%s', %s, %s, %s, '%s')"""
 23     sqli="insert into novel_card  values(%s, %s, %s, %s, %s)"
 24     print sqli %('t4','1','2','0.1','20170707')
 25     cur.execute(sqli, ('t5','1','2','0.1','20170707'))
 26 #cur.execute(sqli,('test5', '100', '1', '0.01', '20170707'))
 27 #sqli="insert into novel_card values('%s','%s')"
 28 #cur.execute(sqli,('test3', '20170707'))

 48 test()
 49 cur.close()
 50 conn.commit()
 51 conn.close()
