Question

i am trying to insert data from excel sheet into database in java. for that i have connected both the database using ODBC. excelsheet has 2 columns cname and title.
after querying the Excel spreadsheet i stored the resultSet values of cname and title into arraylist.

      List Cname = new  ArrayList();
      List Title=new ArrayList();

            Cname.add(rs.getString("Cname"));
            Title.add(rs.getString("Title"));

this will result like this

      [aaa, bbb,cccc, dddd]
      [tree,human,animal,bird]

when i try to insert this into SQL database using insert query it is getting stored like this.

    statement1.executeUpdate("INSERT INTO dbo.company (Cname,Title)  SELECT      
   '"+Cname+"','"+Title+"'");


       Cname                               Title

    [aaa, bbb,cccc, dddd]        [tree,human,animal,bird]

but i want to store this as

      Cname               Title
     ___________________________
      aaa                  tree
      bbb                 human
      cccc                animal
      ddd                  bird

how do i do this???pls help to solve in this.

Answer 1

You’ll have to insert/update the list values, actually you’re inserting the string representations of the entire lists..

Assuming, both lists do exist (not null) and have the same length, then this is a trivial solution:

for (int i = 0; i < Cname.size(); i++ {
   statement1.executeUpdate("INSERT INTO dbo.company (Cname,Title)  SELECT      
     '"+Cname.get(i)+"','"+Title.get(i)+"'");
}

Note – every java class has an implementation of the toString() method, and that method is called, when you “use an object as a string”, like in the expression to create the SQL statement. For lists, the method returns a String that simply includes the (String-representations of) the list element in brackets.
