hsqldb ignores first insert operation on table at server (server needs to be "warmed up"?) -

hsqldb ignores first insert operation on table at server (server needs to be "warmed up"?) -

We have a very curious problem with hsqldb. We are running a few tests which work well on MySQL, but We recently switched to hsqldb for our unit tests. In doing so, we saw that some of our tests have failed, three records A, B and C have been recorded in an examination, and an attempt has been made to regain the first two, A and B. However, for the first time, we only run tests on a new configuration (empty) database. However, if we repeat the test on the same database, both A and B are returned (before you ask, yes, A and B are different from A, B and C).

We have tried to force the database to continue the record, and we have delayed, except for putting the same "heating the database", nothing seems to be done. If we check the hsqldb log, they all are included in the statement to insert, even those people we are unable to use SELECT in our first run on the database.

Has anyone ever experienced problems with hsqldb "hot" with a dummy insert statement? If we do an assembly statement with garbage before running our tests, then they will also successfully

We have tested on hsqldb 2.0.0 and 2.1.0. Both versions produce the same result.

I have never hsqldb, but you have tried INSERT ...; COMMIT; and then SELECT .. run?

This is not inappropriate for a database operation (INSERT, UPDATE or DELETE) may be delayed when it is not possible The database may not be under heavy load but you can not trust it.

Integrate flash games in android app? -



    3 is a flash game that I want to integrate into a menu / list in the Android app. So when the user selects the game from the list, the game starts with the help of the Android Flash Player.   Is it better or better with webwave?   Is there any good tutorial?   Thank you! Adobe Flash provides a good way: you can create a breeze for the Android app.    Use this to create your menu and compile three games in your air app.   Here are some tutorial links about how to publish AiI for Android applications and:   PART1: AIR for Android, PART2:   Publication for Android apps: Ai:   I do not believe that the Android Flash Player can be launched with a single intention so far, so using Java Android will not solve it (now ) And   and a third approach Whatever you mentioned, it should work - using the webwave.
