Is the getClientInfoProperties() method supported by sqljdbc JDBC driver?

No. The instance getClientInfoProperties() method on java.sql.DatabaseMetaData interface is not supported by sqljdbc JDBC driver in all versions.

You can use the following Java example to test the DatabaseMetaData() method:

// Copyright (c) 2016 FYIcenter.com
import java.sql.DriverManager;
import java.sql.Connection;
import java.sql.DatabaseMetaData;
import java.sql.ResultSet;

// Demo of sqljdbc JDBC connection getClientInfoProperties() not supported
public class SqlServerGetClientInfoProperties {
   public static void main(String [] args) throws Exception {

      // sqljdbc JDBC connection URL with instance name appended to host name
      String url = "jdbc:sqlserver://localhost\\SQLEXPRESS;user=sa;password=fyicenter";
      Connection con = DriverManager.getConnection(url);
      System.out.println("JDBC connection URL: "+url); 
      System.out.println("   Connected to: "+con.getCatalog()); 
      
      System.out.println("All properties:"); 
      DatabaseMetaData meta = con.getMetaData();
      ResultSet rs = meta.getClientInfoProperties();
      while (rs.next()) {
         System.out.println("      "+rs.getInt("NAME")+", "
            +rs.getString("DESCRIPTION"));
      }
      con.close();
   }
}

You can compile and run the above example in a command window as shown below:

C:\fyicenter>\local\jdk-1.8.0\bin\javac 
   SqlServerGetClientInfoProperties.java

C:\fyicenter>\local\jdk-1.8.0\bin\java
   -cp .;C:\local\sqljdbc_6.0\enu\sqljdbc42.jar 
   SqlServerGetClientInfoProperties

JDBC connection URL: 
   jdbc:sqlserver://localhost\SQLEXPRESS;user=sa;password=fyicenter
   Connected to: master
All properties:

This confirms that the sqljdbc JDBC driver does not support the getClientInfoProperties() method.
