3、python脚本连接本地mysql数据库读取表数据

#coding:utf-8
from pymysql import connect
data_list=[]

# 将数据存入数据库
conn = connect(host="10.36.128.83",
               port=20002,
               database="sthjj_sthj",
               user="lw_lwc",
               password="***********",
               charset="utf8")

cursor = conn.cursor()

try:
    sql = "SELECT RIVER_SQUARE FROM v_lwhb_river_info"
    cursor.execute(sql)
    RIVER_SQUARES=cursor.fetchall()
    for RIVER_SQUARE in RIVER_SQUARES:
        RIVER_SQUARE1=list(RIVER_SQUARE)
        data_list.append(str(RIVER_SQUARE1[0]))
    print(data_list)
    print(len(data_list))
except:
    print('异常!')
cursor.close()
conn.commit()
conn.close()

print("*"*100)
