pyqt5最简单操作数据库

Posted 2020-10-03 金明爱python

要先安一个包才能使用QtSql
通过新立得安装



import PyQt5.QtSql as sql

db=sql.QSqlDatabase.addDatabase(\'Qmysql\')
db.setDatabaseName(\'test1\')
db.setUserName(\'root\')
db.setPassword(\'123\')
db.open()

query=sql.QSqlQuery(\'select * from a1\')
query.first()
for i in range(query.size()):
    print(query.value(0),query.value(1))
    query.next()

db.close()
