python怎么創(chuàng)建數(shù)據(jù)庫連接池?
MySQL connection method import MySQL dbconn without connection pool=MySQLdb.connect連接(主機=“l(fā)ocalhost”,用戶=“root”,密碼=“pwd”,數(shù)據(jù)庫=“myDB”,端口=3306)cur=連接光標()SQL=“從表1中選擇*”r=當前執(zhí)行(SQL)r=當前fetchall() 當前關(guān)閉() 連接關(guān)閉()使用連接池后的連接方法導入MySQL數(shù)據(jù)庫發(fā)件人DBUtils.PooledDB文件import PooledDBpool=Pooleddb(mysqldb,5,host=“l(fā)ocalhost”,user=“root”,passwd=“PWD”,DB=“mydb”,port=3306)?5是連接池中的最小連接數(shù)
