python通过MySQLdb模块连接查询mysql数据详解编程语言

这段代码通过MySQLdb模块连接mysql数据库，然后查询employee表中income字段大于1000的数据输出

#!/usr/bin/python 
  
import MySQLdb 
  
# Open database connection 
db = MySQLdb.connect("localhost","testuser","test123","TESTDB" ) 
  
# prepare a cursor object using cursor() method 
cursor = db.cursor() 
  
# Prepare SQL query to INSERT a record into the database. 
sql = "SELECT * FROM EMPLOYEE / 
       WHERE INCOME > '%d'" % (1000) 
try: 
   # Execute the SQL command 
   cursor.execute(sql) 
   # Fetch all the rows in a list of lists. 
   results = cursor.fetchall() 
   for row in results: 
      fname = row[0] 
      lname = row[1] 
      age = row[2] 
      sex = row[3] 
      income = row[4] 
      # Now print fetched result 
      print "fname=%s,lname=%s,age=%d,sex=%s,income=%d" % / 
             (fname, lname, age, sex, income ) 
except: 
   print "Error: unable to fecth data" 
  
# disconnect from server 
db.close()
