Error while Running App with Database Connector and CSV Module
0
Hello everyone, I am relatively new to Mendix, and I am having the following issues with my App: I am trying to create an app that displays data from a database. For that I am using the Database Connector Module with many SQL Queries. I also want to be able to export some data to a .csv file. For that I am using the CSV Module. However it seems like this module somehow stops my SQL Queries from working. If I do not use the CSV Module but have it imported into my project and try to run the App (which works without the CSV Module) all data from SQL Queries are not shown in the App. I also attached a Screenshot of how Mendix Studio Pro looks like as well as an file with the error Message. Any idea on how to fix this or how to work around using the CSV module? An unhandled error occurred in the MxRuntime. -------- java.lang.UnsupportedClassVersionError: com/microsoft/sqlserver/jdbc/SQLServerDriver has been compiled by a more recent version of the Java

You need a version of the MSSQL JDBC jar file that uses Java 11. The error you are seeing is because the jar file you’re using is using a more recent version of Java that Mendix does not support.
Maybe try this version and see how that works: mssql-jdbc-10.2.0.jre11.jar
