Question

我是一名PHP开发人员。我正在尝试使用pyqt创建一个小应用程序我使用的代码效果很好

 import psycopg2

 try:
   myConnection = psycopg2.connect(host="localhost", user="openpg", password="", dbname="dbLaSolve")
   conn = myConnection.cursor()

 except(Exception, psycopg2.Error) as error :
   if(myConnection):
        print("Failed to insert record", error)

 sql = "insert into trens(nom,prenom)VALUES('RASOLO','Solofo')"
 conn.execute(sql)
 myConnection.commit()

但是我想将其分为两个文件示例 conn.py 用于零件连接， insert.py 将数据插入表postgreql 对于那些了解php的人来说像这样

connex.php

try
{
    $conn = new PDO('mysql:host=localhost;dbname=dbLaSolve','root','');
}
catch(Exception $err)
{
    echo "Erreur de connexion à la base de donnée: ".$err->getMessage();
    exit();
}

insert.php

require_once("connex.php");
$sql = "INSERT INTO trens ( `nom`, `prenom`)VALUES ('RASOLO','Solofo')";
$conn->exec($sql );

Answer 1

文件： connex.py

import psycopg2
myConnection = psycopg2.connect(host="localhost", port=5432, user="postgres", 
password="mypass", dbname="dell")
conn = myConnection.cursor()

和文件 insert.py（导入连接）

from connect import  myConnection,conn,psycopg2

try:
    sql = "insert into trens VALUES('hola','mundo')"
    conn.execute(sql)
    myConnection.commit()

except(Exception, psycopg2.Error) as error :
    if(myConnection):
        print("Failed to insert record", error)

与psycopg2 postgresql连接的python文件
