Question

I have an ORACLE SQL sctipt with several queries and tables, and I wan to run that script from my java program at the starting of the program to ensure that everything is on the right place. I found a code to run the script, but it doesn’t work for some reason. Can anyone provide me samples so that I can follow it.

This is what I found :

try {
    String line;
    Process p = Runtime.getRuntime().exec ("psql -U sas -d oracle -h @localhost -f Lab_05_Tables.sql");
    BufferedReader input =new BufferedReader(new InputStreamReader(p.getInputStream()));

    while ((line = input.readLine()) != null) {        
        System.out.println(line);
    }
    input.close();
}
catch (Exception err) {
    err.printStackTrace();
}

But it doesn’t work though.

Error

java.io.IOException: Cannot run program "psql": CreateProcess error=2, The system     
cannot find the file specified

Answer 1

It would be much better, if you have resources, to port SQLs from your script into Java program itself.

See Java JDBC tutorial.
