@Alexander – this is correct. Matlab stopped including sqlite4java in R2021b (it was still included in 21a). You can download the open-source sqlite4java project from https://code.google.com/archive/p/sqlite4java or https://bitbucket.org/almworks/sqlite4java/src
Note that sqlite4java is not actively maintained: the last commit was in 2019, and the downloaded binaries use a rather outdated version of the sqlite database (3.8.7).

When using sqlite in Matlab I usually prefer using the mksqlite utility (http://mksqlite.sourceforge.net), which is actively maintained and works [extremely well] with the latest sqlite versions.

Thank you for your post. Is it possible to use Matlab functions inside the SQL query for method using sqlite-jdbc? I see here that you can create custom callback functions in Java: https://stackoverflow.com/questions/3192443/writing-user-defined-sql-functions-for-sqlite-using-java-or-groovy. And Matlab let’s call it’s functions from Java: https://www.mathworks.com/help/matlab/matlab_external/execute-matlab-functions-from-java.html. So my idea was to try and call a Matlab function inside the custom Java callback function. However, I’m not sure how to interact with the JDBC via Matlab besides the standard SQL queries. Any advice would be appreciated!

Andrea – sqlite4java is an open-source project (https://code.google.com/archive/p/sqlite4java). You can modify its code and/or submit an issue on that project’s repo (https://bitbucket.org/almworks/sqlite4java/issues).
