![]() ![]() Try to limit the amount of data your client application retrieves from the big database. So if you were to index everything, you would likely make performance worse. One caveat about indexes is that they add overhead for Insert, Update, and Delete operations because the database engine must revise indexes in addition to the table where the changes occur. I'm not sure about other Access versions. In Access 2003 the Performance Analyzer is available from Tools -> Analyze -> Performance. If you have little experience with indexing, try the Performance Analyzer tool to get you started. For example if you have a query which includes "WHERE somefield = 27", data retrieval can be much faster if you create an index on somefield. Indexing can reduce the pain considerably. Thanks Gord Thompson, you helped me a lot.You may find data retrieval painfully slow with a large Access database. ![]() When the wizard completed it opened my LibreOffice database and I could see the tables in the. In Step 4, I saved the LibreOffice Base database as “accdbTest.odb” in my Documents folder. In Step 3, I left the “User name” field empty and just clicked “Next >”. The Access file I wanted to manipulate was named “baseTest.accdb” in my Downloads folder, so in Step 2 the “Datasource URL” was jdbc:ucanaccess:///home/abrar/Downloads/baseTest.accdbĪnd the “JDBC driver class” was ![]() Then I launched LibreOffice Base, and in Step 1 of the wizard I chose “Connect to an existing database (JDBC)” Note that you must close and re-open LibreOffice for the new Class Path values to take effect. home/abrar/Downloads/UCanAccess-2.0.9.5-bin/lib/hsqldb.jar home/abrar/Downloads/UCanAccess-2.0.9.5-bin/lib/commons-logging-1.1.1.jar home/abrar/Downloads/UCanAccess-2.0.9.5-bin/lib/commons-lang-2.6.jar On the Advanced tab I clicked the “Class Path…” buttonĪnd then added the following five (5) JAR files using the “Add Archive…” button: /home/abrar/Downloads/UCanAccess-2.0.9.5-bin/ucanaccess-2.0.9.5.jar I launched LibreOffice (not Base, just LibreOffice itself) Then I downloaded UCanAccess to my Downloads folder and unzipped it. Here’s how I did it on a clean install of Ubuntu 14.04 LTS.įirst, I installed LibreOffice Base itself sudo apt-get install libreoffice-base ![]() We can use the UCanAccess JDBC driver to connect to Access databases (.mdb and. ![]()
