python使用pyodbc连接sqlserver

pip install pyodbc

pip list

import pyodbc
 
 
class MSSQL:
    def __init__(self, IP, UserID, Pwd, db):
        self.host=IP;
        self.user=UserID;

        self.dbname=db;
 
    def __getConnect(self):
        if not self.dbname:
            raise(NameError,"db name undefine error")
        else:

            ##example: Driver={ODBC Driver 11 for SQL Server};SERVER=127.0.0.1,1433;DATABASE=MyTestDB;UID=sa;PWD=Abc123
            self.conn = pyodbc.connect(connSTR);
            cu= self.conn.cursor();
        if not cu:
            raise(NameError,"db connect error");
        else:
            return cu;
 
    def ExecuteTableQuery(self,selectSql):
        cuu = self.__getConnect();
        selectRows = cuu.execute(selectSql);
        resList=selectRows.fetchall();
        self.conn.close();
        return resList;
 
    def ExecuteNonQuery(self,sql):
        cuu = self.__getConnect();
        cuu.execute(sql);
        self.conn.commit();
        self.conn.close();
 
    def PrintODBCDrivers(self):
        print(pyodbc.drivers() );
