问题 I'm trying to access my application's tables in Play! Framework, but I can't find it using the console. For instance, I have two entity models: Address and Campus . I can create objects and save normally, but I would like to see the changes in fs or mem DB, but the H2 console doesn't show the tables Address and Campus . I'm using the default settings to log in localhost:9000/@db . What am I doing wrong? Thanks in advance. 回答1: The correct URL for the inmemory database is: jdbc:h2:mem:name-of

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I would like to use the H2 database on Ubuntu 12.10, and went to the website and got the platform independent install file.

There are no configure or makefiles that I can find, and the documentation doesn't mention anything, and there I can't find anything using google. I don

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I've got a H2 database with URL "jdbc:h2:test" . I create a table using CREATE TABLE PERSON (ID INT PRIMARY KEY, FIRSTNAME VARCHAR(64), LASTNAME VARCHAR(64)); . I then select everything from this (empty) table using SELECT * FROM PERSON . So far, so good. However, if I change the URL to "jdbc:h2:mem:test" , the only difference being the database is now in memory only, this gives me an org.h2.jdbc.JdbcSQLException: Table "PERSON" not found; SQL statement: SELECT * FROM PERSON [42102-154] . I'm probably missing something simple here, but any
