1.今日收获内容
数据库插入操作
import MySQLdb # 打开数据库连接 db = MySQLdb.connect("localhost", "testuser", "test123", "TESTDB", charset='utf8' ) # 使用cursor()方法获取操作游标 cursor = db.cursor() # SQL 插入语句 sql = """INSERT INTO EMPLOYEE(FIRST_NAME, LAST_NAME, AGE, SEX, INCOME) VALUES ('Mac', 'Mohan', 20, 'M', 2000)""" try: # 执行sql语句 cursor.execute(sql) # 提交到数据库执行 db.commit() except: # Rollback in case there is any error db.rollback() # 关闭数据库连接 db.close()
数据库查询操作
import MySQLdb # 打开数据库连接 db = MySQLdb.connect("localhost", "testuser", "test123", "TESTDB", charset='utf8' ) # 使用cursor()方法获取操作游标 cursor = db.cursor() # SQL 查询语句 sql = "SELECT * FROM EMPLOYEE \ WHERE INCOME > %s" % (1000) try: # 执行SQL语句 cursor.execute(sql) # 获取所有记录列表 results = cursor.fetchall() for row in results: fname = row[0] lname = row[1] age = row[2] sex = row[3] income = row[4] # 打印结果 print "fname=%s,lname=%s,age=%s,sex=%s,income=%s" % \ (fname, lname, age, sex, income ) except: print "Error: unable to fecth data" # 关闭数据库连接 db.close()
