首先开启开启oracle数据库,同时也要开启侦听端口,使用命令lsnrctl status产看,lsnrctl start开启 import cx_Oracle db=cx_Oracle.connect('system','dingjia','192.168.88.213/orcl11') #获取connection对象 cursor=db.cursor() #获取游标对象 create_table="""create table python_modules( module_name VARCHAR2(50...

python -m pip install oracledb Usage is like: import getpass import oracledb un = 'scott' cs = 'localhost/orclpdb1' pw = getpass.getpass(f'Enter password for {un}@{cs}: ') with oracledb.connect(user=un, password=pw, dsn=cs) as connection: with connection.cursor() as cursor:...

我不确定我是否理解python中DB连接池的用例(例如:心理学、2、池和mysql.connector.pooling)。在我看来,在python中,由于GIL,通常使用多进程而不是多线程方法来实现并行性,而在多进程情况下,这些池并不十分有用,因为每个进程都将初始化自己的池,并且一次只运行一个线程。这是正确的吗?在使用多个进程时,是否存在...
