问题 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.

Is there a tool other than ij to look into a local derby database (folder)?

I'm using Derby ij to look into my local Apache Derby database. It's just a folder and I connect to it like this: connect 'jdbc:derby:C:\Users\Torben\MyDatabase' USER 'me' PASSWORD 'secret'; It works, but I don't really like to look into the database in the console. Is there another tool for this? The best would be something with a GUI. Bryan Pendleton Squirrel SQL can connect to an Apache Derby database. Getting Started using the SQuirreL SQL Client I simply use NetBeans IDE (Services -> Databases) to connect to my local or remote derby databases. You can also create new derby databases there

Issue with NoClassDefFoundError error in a web environment Spring/Wicket/Derby/Jetty

Using timestampdiff in a Derby WHERE clause

由 倾然丶 夕夏残阳落幕 提交于 2019-11-28 08:57:32
问题 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

Setting up an embedded Derby database in a standalone Java application

由 独自空忆成欢 提交于 2019-11-28 06:50:22
I'm trying to setup an embedded Derby database for a standalone Java application, but after pouring through all sorts of documentation, I just can't seem to find any simple explanations or examples. I'm using Eclipse with the Derby plugin and have enabled Derby nature for my project. I found an example of using an embedded Derby database in a standalone address book as well as an overview of using Derby in Eclipse (that doesn't seem to cover the embedded deployment), but I still feel like I'm missing something fundamental. This is my first time attempting to use a database with Java, and I'm a

Using sql DATEADD function in java

由 时间秒杀一切 提交于 2019-11-28 05:12:35
问题 When I run queries using DATEADD it seems that the database does not recognize this function. also when I just run select DATEADD(Month, -3, GETDATE()) I'm getting: Error code -1, SQL state 42X01: Syntax error: Encountered "<EOF>" at line 1, column 36. I added the JAR file from hsqldb-2.2.9 as you can see What am I missing here? 回答1: Derby does not have a DATEADD function. You need to use the JDBC function timestampadd to achieve this: select {fn TIMESTAMPADD(SQL_TSI_MONTH, -3, CURRENT
