Question

I have a database in which i have 3 columns (id, name, info_link).

I have the id and names stored in the database.

I have a text file where i have all the info links scraped.

Info link is in the form of : http://someURL/**Name**.htm

Now what I want to do is Take a name from the database, read a line from the text file of links, find if the link(line) contains that drug name, put that link in the info_link column of the record.

This is what my code is

BufferedReader reader = new BufferedReader(new FileReader("./Links.txt"));
BufferedWriter writer = new BufferedWriter(new FileWriter("./AddedLinks.txt"));
int id = 1;
//Creates a connection to the Database
connection = DriverManager.getConnection(DB_URL,DB_USER,DB_PASS);

statement = connection.createStatement();
for(id=1;id<=1153;)
{   
   query = statement.executeQuery("SELECT name FROM drug_list WHERE id = '"+id+"';");
   query.next();
   String name = query.getString(1);
   String words[] = name.split(" ");
   String Myvalue = reader.readLine();
   boolean Found = false;
   while(!Found)
      if(Myvalue.toLowerCase().contains(words[0].toLowerCase()))
      {
         Boolean f = false;
         System.out.println("Found"+name);
         update = connection.prepareStatement("UPDATE drug_list SET info_link = ? WHERE id = ?;");
         update.setString(1, Myvalue);
         update.setInt(2, id);
         f = update.execute();
         if(!f)
         {
            System.out.println("QSE");
            id++;
            writer.write(Myvalue);
            Found = true;
         }

      }
      else
      {
         System.out.println("Could Not Find"+name+"\n");
         id++;
         Found = false;
      }
}

I am able to match the container links that have to be processed on Single Words. But the problem is

I have a drug names like

• Albuterol (Salbutamol)
• Dorzolamide/Timolol

etc..

And Their Corresponding Links like :

 - http://Somelink/**albuterol_salbutamol**.htm
 - http://Somelink/**dorzolamide_timolol**.htm

Also there are a few Names in the Database that do not have a corresponding link in the text file, i also want to skip those. I have 1153 Values in total in my database.

Also I have a few drug names like

• Calcium Something
• Calcium Something Something
• Calcium Not Something

So this creates a problem IF i am matching just the word[0] that i split up. Because it will update all the values for Calcium Something Field Only.

Answer 1

You use a regex to split the words. Something like

String words[] = a.split("[/()]");

and iterate over and check all the words instead of just one word.
