Python uses MySQLdb to access the mysql database, mysqldbmysql
This example describes how to access the mysql database using MySQLdb in python. Share it with you for your reference. The details are as follows:
#!/usr/bin/pythonimport MySQLdbdef doInsert(cursor,db): #insert # Prepare SQL query to INSERT a record into the database. sql = "UPDATE EMPLOYEE SET AGE = AGE+1 WHERE SEX = '%c'" %('M') try: cursor.execute(sql) db.commit() except: db.rollback()def do_query(cursor,db): 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() print 'resuts',cursor.rowcount 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"def do_delete(cursor,db): sql = 'DELETE FROM EMPLOYEE WHERE AGE > {}'.format(20) try: cursor.execute(sql) db.commit() except: db.rollback()def do_insert(cursor,db,firstname,lastname,age,sex,income): sql = "INSERT INTO EMPLOYEE(FIRST_NAME, \ LAST_NAME, AGE, SEX, INCOME) \ VALUES ('%s', '%s', '%d', '%c', '%d' )" % \ (firstname,lastname,age,sex,income) try: cursor.execute(sql) db.commit() except: db.rollback()# Open database connection# change this to your mysql account#connect(server,username,password,db_name)db = MySQLdb.connect("localhost","hunter","hunter","pydb" )# prepare a cursor object using cursor() methodcursor = db.cursor()do_query(cursor,db)doInsert(cursor,db)do_query(cursor,db)do_delete(cursor,db)do_query(cursor,db)do_insert(cursor,db,'hunter','xue',22,'M',2000)do_insert(cursor,db,'mary','yang',22,'f',5555)do_insert(cursor,db,'zhang','xue',32,'M',5000)do_insert(cursor,db,'hunter','xue',22,'M',333)do_query(cursor,db)# disconnect from serverdb.close()
