Question

运行命令时

C:\Program Files (x86)\H2\bin>java -cp h2.jar org.h2.tools.Shell -url "jdbc:h2:tcp://localhost/~/couponvalidationservice" -user "sa" -password "" -driver "org.h2.Driver"

我收到以下错误。我不确定如何显示其余的8条错误消息。我试图连接到该网站，以便无需打开Webportal即可运行一些sql命令对其进行配置。

Answer 1

我能够通过将“ tcp”部分替换为“ file：〜/ couponvalidationservice”来解决此连接问题，这使我可以连接，然后对所需的数据库运行SQL命令。

H2通过外壳“连接断开”连接到网站
