Try using the Help within MatLab, its very helpful.
You are using the correct database connection:
conn = database(instance,username,password,driver,databaseurl)
The example provided by MatLab looks like this:
Connect to an Oracle database via JDBC driver.
Connect to the database, test_db, using the user name, scott, and password, tiger. Use the JDBC driver, oracle.jdbc.driver.OracleDriver, to make the connection. The URL defined by the driver vendor is jdbc:oracle:oci7:
conn = database('test_db','scott','tiger',...
'oracle.jdbc.driver.OracleDriver','jdbc:oracle:oci7:')
OR
Microsoft SQL Server Authenticated Database Connection
Connect to a Microsoft SQL Server database with integrated Windows Authentication using a JDBC driver.
Close MATLAB if it is running.
Insert the path to the database driver JAR file in the classpath.txt file. The classpath.txt file is located at:
$MATLABROOT\toolbox\local\classpath.txt
The updated path entry should now include the full path to the driver. For example:
C:\DB_Drivers\sqljdbc_2.0\enu\sqljdbc4.jar
Insert the path to the folder containing sqljdbc_auth.dll in the librarypath.txt file. The librarypath.txt file is located at:
$MATLABROOT\toolbox\local\librarypath.txt
The path entry should not include the file name sqljdbc_auth.dll:
C:\DB_Drivers\sqljdbc_2.0\enu\auth\x64
The sqljdbc_auth.dll file is installed in the following location:
<installation>\sqljdbc_<version>\<language>\auth\<arch>
where is the installation directory of the SQL server driver.
- If you are running a 32-bit Java Virtual Machine (JVM), then use the
sqljdbc_auth.dll file in the x86 folder, even if the operating system
is the x64 version.
- If you are running a 64-bit JVM on a x64 processor, then use the
sqljdbc_auth.dll file in the x64 folder.
- If you are running a 64-bit JVM on a IA-64 processor, then use the
sqljdbc_auth.dll file in the IA64 folder.
Start MATLAB.
Use the AuthType parameter to establish a Windows Authentication connection.
conn = database('dbName','','', ...
'Vendor','Microsoft SQL Server','Server','servername',...
'AuthType','Windows')
