I am trying to connect to SQL through Matlab and my command is
conn = getDBconnection([server name]);
and I am getting the following error:
Error using database (line 158)
Java exception occurred:
java.lang.UnsupportedClassVersionError: com/microsoft/sqlserver/jdbc/SQLServerDriver : Unsupported major.minor version 52.0
Has anyone seen this?

The major.minor version 52.0 indicates that the java code you are using has been compiled using Java 8 compiler. For more information on major.minor version numbers refer http://www.rgagnon.com/javadetails/java-0544.html
Java code compiled by a compiler of a particular version can only be executed by java runtimes of that version or newer versions. To check which version of java, MATLAB is using run this command in MATLAB command prompt:
>>version -java
The Error: " java.lang.UnsupportedClassVersionError " is being raised because of the incompatibility between the compiled JAR and the run time java being used by MATLAB. Just make sure you are using a compatible runtime (which is Jre8 or higher in your case).
