derby

i want to use hibernate with embedded derby in a standalone application , and i have some questions: What jars do i need ? What are the necessary hibernate configuration ? Are there any other necessary configuration ? Does it have any problems/limitations with queries/criteria ? if you can also suggest me some good tutorial for this approach that will be preferable, thanks in advance. I use Apache Derby with Hibernate for testing one of my project's model classes (their equals , hashCode implementations, queries, etc.). MySQL is used as the production database. I choose Derby instead of HSQLDB

I'm using derby as an embedded database. Furthermore, I'm using it's in-memory database option for my unit tests. What I can't figure out is how to properly shut down (A quick look at the code) the Derby database. I beleive I have it working for a standard database but I'm getting different exceptions when attempt similar code on a in-memory database. I'm going to omit details, I'll add them if other feel are needed. Basically, I'm trying to shut down my database in these two fashions where my in-memory database is consistently called "eh": DriverManager.getConnection("jdbc:derby:memory:eh

公司的项目使用IDEA+Weblogic搭建，每次启动项目时都是提示此信息， 每次都要手动关闭CMD窗口很烦。 首先找到Weblog安装目录，然后再部署的域下面找到bin目录 找到setDomainEnv.cmd和 setDomainEnv.sh这两个版本，一般windows都是使用.cmd后缀的文件，我们打开此文件，找到 @REM Set DERBY_FLAG, if derby is available. if exist %WL_HOME%\common\derby\lib\derby.jar ( set DERBY_FLAG=true ) 找到这段，讲DERBY_FLAG=true改为false 来源： CSDN 作者： zhonghe0820 链接： https://blog.csdn.net/u012884074/article/details/82470516

I'm using the Apache Derby embedded database for unit testing in a Maven project. Unfortunately whenever I run the test I end up with the derby.log file in the root of the project. The database itself is created in the target directory ( jdbc:derby:target/unittest-db;create=true ) so that is not a problem. After consulting the reference guide I tried setting the logDevice parameter on the JDBC url ( jdbc:derby:target/unittest-db;create=true;logDevice=/mylogs ) but that seems to be for a different log, hence derby.log still appears. Any help is much appreciated. stevedbrown You can get rid of

I am trying to retrieve an image stored as a CLOB in a Derby DB via a Worklight SQL adapter. I would like to do something similar to what was written up here: https://www.ibm.com/developerworks/community/blogs/dhuyvett/entry/jsonstore_revisited_in_worklight_v6_part_1_the_adapter?lang=en except for the referenced article the author is using DB2. Does anyone know how I can do this in Derby? Currently when I go to retrieve the image doing a SQL Select, the string returned is "IMAGE": "org.apache.derby.impl.jdbc.EmbedClob@2d236" I would also consider mysql as an alternative. Thanks for any

I have a Derby Database in Netbeans with connection string jdbc:derby://localhost:1527/MyDatabase Can this be used with ODBC? If so, how could I transform this or configure my Derby Database to be compliant with ODBC The end goal is to get the Derby Database migrated to MySQL. Using the migrating wizard in MySQL Workbench appears to be the easiest way. However I do need ODBC connectivity. Michał Niklas Do you want to use ODBC because MySQL Workbench uses it to migrate database? I migrated some databases between various engines and my favorite technology is to convert DDL schema ( CREATE TABLE

I am trying to build a simple JDBC Spring Template application, the web framework I am using is wicket and under the jetty 6 web server (through the Jetty Maven Plugin). Also, I am building the app with Eclipse. For some reason, I am getting a NoClassDefFoundError with the Derby jdbc class. I am assuming I would get a class not found exception was not found, so am guessing something else is happening. The derby class is part of the classpath, the WEB-INF/lib directory. What do you think the issue is? My thoughts on the problem: It is not a "jar not found in the classpath" error but more an

I would like to simulate the effect of the following type of query (that is in Microsoft SQL Server syntax) in a Derby database. The goal is to return all records in the table where the date stored in "someColumn" is less than 7 days old. Here is the Microsoft SQL syntax for what I wish to achieve... select * from someTable where datediff(dd, someColumn, getdate()) < 7 I have been able to determine that in Derby it will involve use of the timestampdiff function. But the syntax of the usage of functions in a WHERE clause in Derby is unknown to me and I cannot find any examples. I have found

Hi I am having trouble executing the following function without running into the following exception. I'm not sure why this is happening. I think it might have something to do with the quotes. I am using derby database if it matters. java.sql.SQLSyntaxErrorException This is the following code I am trying to execute: public void addAlbum(Album album) throws IOException, SQLException { Properties props = new Properties(); FileInputStream in = new FileInputStream("database.properties"); props.load(in); in.close(); props.getProperty("jdbc.drivers"); String url = props.getProperty("jdbc.url");
