Hi,

I have a MATLAB script that I used to run by connecting to the postgres database that is hosted on the server(Openshift).

I used to do port forwarding using database toolbox and hardcode the port number (see below 60733) in the MATLAB script each time to connect to the database

I'd like to automate this process so that when I open MATLAB I can directly run the script without having to generate the port manually all the timet. Is there any way to automare this DB connection ?

Note : I'm using Openshift PostgreSQL databse server hence I need to port forward from my machine to connect to this server

I have used database toolbox to connect the server DB using below credentials

databasename = 'employeedb';
username = 'user';
password = 'user123';
driver = 'org.postgresql.Driver';
url = 'jdbc:postgresql://localhost:60733/employeedb';
conn = database(databasename,username,password,driver,url);
countSqlquery = "SELECT COUNT(*) as count_pet FROM employees";
rowCount = select(conn,countSqlquery);
