#判断表存不存在来创建表

def create_table():


    conn = sqlite3.connect(db_name)
    try:
        create_tb_cmd='''
        CREATE TABLE IF NOT EXISTS USER
        (NAME TEXT,
        AGE INT,
        SALARY REAL);
        '''
        #主要就是上面的语句
        conn.execute(create_tb_cmd)
    except:
        print "Create table failed"
        return False
    insert_dt_cmd='''
    INSERT INTO USER (NAME,AGE,SALARY) VALUES ("Rocky",10,20.1);
    '''
    conn.execute(insert_dt_cmd)
    conn.commit()
    conn.close()
