達(dá)夢(mèng)數(shù)據(jù)庫(kù)
===================
主機(jī)名LOCALHOST

賬號(hào)名
SYSDBA

登錄密碼
123456789

數(shù)據(jù)庫(kù)名DAMENG

實(shí)例名DMSERVER


端口5236


=====================
Pycharm默認(rèn)沒有連接達(dá)夢(mèng)的驅(qū)動(dòng)，首先選擇給Pycharm添加一個(gè)達(dá)夢(mèng)的驅(qū)動(dòng)。

找到自己電腦上達(dá)夢(mèng)的JDBC驅(qū)動(dòng)，因?yàn)槲译娔X上安裝了達(dá)夢(mèng)數(shù)據(jù)庫(kù)，所有的驅(qū)動(dòng)文件都在他的安裝目錄里。

通過(guò)驅(qū)動(dòng)方式選擇創(chuàng)建數(shù)據(jù)庫(kù)連接。
