I have a java program using a derby db in Eclipse. I want to use this derby db data with a new program I am about to create with the Lazarus ide. Can I connect direct to the derby db, if so how. Or do I need to export the derby db in some way to use with the Lazarus ide, if so how would I do this?
if you decide with export variant, then .csv (comma separated value) is probably the best inter database.
I have some experience with tdbf.
But from what I've read sqlite will be the best option.
I'm sorry for posting this as answer i have only 42 points reputation and can't post it as comment (need 50 for it)
Does derby support ODBC? Lazarus has a ODBC connection that can be used to connect databases that are not directly supported.
I searched quickly, but mostly saw references to older commercial Derby ODBC drivers. And it will probably depend on OS.

I am trying to setup a temporary unit test database that has DB2 style syntax. I know Derby fills this role quite nicely on our Java applications.
I have done much searching, and I have seen that you can use the JDBC DB2 driver to connect to Derby - which is cool, except it doesn't seem as true for the ODBC DB2 (or OLEDB) driver allowing a connection to Derby.
I also saw that Cloudscape had a version but following the download instructions, there is a redirect page that states:
There is no replacement for the old Cloudscape ODBC driver in IBM's world. Does anyone know of another source where I can get it? Or another way of connecting to Derby from VB6 (or of creating an ADODB.Connection in VB.net to Derby).
I suppose I would settle for an old version of Derby that the you can connect with (an old) DB2 ODBC driver.
I like understand the 'Hive ODBC Connector' concept. means What is a use of Hive ODBC Connector in the architecture.
Does it require to set-up the DSN (data source Name ). Can we go for DSN-less configuration ?
Please explain in details
If you have one of the distributions from Cloudera, Hortonworks, MapR, Intel, Microsoft or DataStax, they already come with an ODBC driver in the distribution. The driver is created by Simba Technologies (http://www.simba.com/connectors/apache-hadoop-hive-odbc).
If you're using the Apache version of Hadoop, you can still trial the version of the ODBC driver on the above link for 30 days, however you will need to pay for it to continue use.
I only mention the above as this ODBC driver is a more complete implementation of the ODBC specification than the open source one, and it can also do SQL-HiveQL translation which essentially means that you can plug it into Excel or Tableau or the like and have them issue standard SQL. As mc110 mentioned, you can make DSN or DSN-less connections and there is also a Windows configuration dialog available should you wish to use that.
Also, in the interests of full disclosure, I work for Simba Technologies.
As explained at https://cwiki.apache.org/confluence/display/Hive/HiveODBC, the Hive ODBC connector implements the ODBC API for Hive, potentially allowing a lot of existing well-written ODBC applications to seamlessly use Hive as they would any other database. The link also explains what API calls are and are not supported.
SQLDriverConnect is supported, which implies you can make DSN-less connections. I suggest you read the information from the link for more information. Also, http://www.cloudera.com/content/cloudera-content/cloudera-docs/Connectors/PDF/Cloudera-ODBC-Driver-for-Apache-Hive-Install-Guide.pdf has a section on configuring DSN-less authentication.
I'd like to use Oracle's SQLdeveloper to visualize my HSQLDB tables.
An instruction on how to use it with MySQL can be found on https://web.archive.org/web/1/http://blogs.techrepublic%2ecom%2ecom/programming-and-development/?p=564 ... and I know that Oracle points to a location where to download all JDBC drivers.
With MySQL this worked, however, including the JAR file from HSQLDB (here: hsqldb-1.8.0.10.jar) did not make a new tab show up (as is the case with MySQL).
Is there a way to "convince" SQLdeveloper working with HSQLDB and JDBC?
FYI, I am using Squirrel too but it's not as comfortable to work with compared to SQLdeveloper.
I was looking for the same thing, then found this:
http://forums.oracle.com/forums/thread.jspa?messageID=4241526�
So basically Oracle doesn't support it, and you can't add a new TAB on your own, even if you have the JDBC driver.
You can try other tool like ExecuteQuery (executequery dot org)
I have an MS-Access mdb file that I need to import data from into my mysql instance. I am on a mac, is there any free/OSS tools that allow me to do that? If not, is there a free/OSS JDBC driver that I can use to extract the data I need?
Thanks.
Have a look at Jackcess. Note that this doesn't support Access 97 databases, however, only 2000+.
For Access 97, the only thing I'm aware of is mdbtools, but that's a C library, so you'll have to write some JNI glue code if you want to use it from Java; also, it's not maintained anymore, to the best of my knowledge.
UCanAccess is a pure-Java JDBC driver that can read from and write to Access 2000 and newer databases. (Access 97 files are supported read-only.) It will work on any machine that runs Java.
For more details see
Manipulating an Access database from Java without ODBC
Is your Access MDB on mac?
Does the mac Access have the option of using linked tables?
If so, you can create a Linked Table from Access MDB to mySQL. Then, you could treat mysql tables as if it were part of MS-Access.
EDIT: See if this helps.
You could export the MDB file using something like this. This won't help you if you need to do it from within your app, but if you are ok exporting the data then using it, then this should help.
I do the following way to convert;
Download ACCDB MDB Explorer
http://accdb-mdb-explorer.en.softonic.com/mac
Open the MDB file
Export as SQL
Import in MySQL using MySQL Workbench.
Hope it helps..
I have tried SQLite in Java, but the speed is slow due to the JDBC driver. Then I tried HSQLDB and thought the speed is good, but I cannot find a good management tool for HSQLDB such as phpMyAdmin for MySQL or SQLite Manager for SQLite.
I'd like to use the manager tool to prepare the test data for unit tests, or use the manager tool to navigate the data after doing some small experiments.
Is there any good tool?
Here are a couple other suggestions you might checkout:
Squirrel SQL http://squirrel-sql.sourceforge.net/
Execute Query http://executequery.org/
Razor SQL (paid) http://www.razorsql.com/
Razor has the best feature set, but is paid. The others are good at different things and worth checking into.
This would only have meaning if you are running in HSQLDB server mode. If you are running in memory or file mode, then you either can't access the DB from another process or doing so would lock it.
In Server mode you could use any universal client. JDBC driver is the hsqldb.jar itself.
Actually HSQL brings its own management tool (which is not super). See http://hsqldb.org/doc/guide/apf.html
I've used Squirrel SQL. It's a universal client for any JDBC database.
See: http://squirrel-sql.sourceforge.net/
