How to access Excel as Database using Java 8

Question

I am using Java 8.

When i am trying to access Excel data(basically this is my test data) through jdbc-odbc, i am getting "java.lang.ClassNotFoundException: sun.jdbc.odbc.JdbcOdbcDriver"

And also i am trying to access data as non DSN.

I surfed net and came to know that Oracle deprecated support to jdbc-odbc.

So what is the easiest way to access this Excel data using Java?

Connection con=null;
    Statement stmt=null;
    ResultSet rs=null;
    String query = "select TestScript from [TS 360 Scripts$]";

    try
    {
        Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver" );
        con = DriverManager.getConnection("jdbc:odbc:;Driver={Microsoft Excel Driver(*.xlsx)};DBQ=D://TS 360 Script with Count.xlsx");


        stmt=con.createStatement();
        rs=stmt.executeQuery(query);
        while(rs.next())
        {
            System.out.println(rs.getString("TestScript"));
        }

        con.close();
        rs.close();
        stmt.close();
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }

Uday- you can easily do whatever you want to do with Apache POI jar

As Your are mentioned your requirement: of all rows having isExecuted String Yes. I tried with this jar.

Try this

package com.dd.selenium;

import java.io.FileInputStream;
import java.io.IOException;

import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;

public class PerformDDTest {

    private static HSSFWorkbook xlWBook;
    private static HSSFSheet xlSheet;
    private static HSSFRow xlRow;
    private static HSSFCell xlCell;
    private static String filePath = "/home/dinesh/";
    private static String fileName = "test.xls";

    public static void main(String[] args) throws InterruptedException {

        try {

            FileInputStream xlFile = new FileInputStream(filePath + fileName);

            // Access the required test data sheet

            xlWBook = new HSSFWorkbook(xlFile);

            // Assuming your data is in Sheet1- if not use your own sheet name
            xlSheet = xlWBook.getSheet("Sheet1");

            // gives row count in sheet
            int noOfRows = xlSheet.getPhysicalNumberOfRows();

            // gives column count in sheet
            xlRow = xlSheet.getRow(0);
            int noOfColumns = xlRow.getLastCellNum();

            // excelData - 2 dimm array - stores all the excel data -Sheet1 only
            String[][] excelData = new String[noOfRows][noOfColumns];

            // r - row c- column
            for (int r = 1; r < noOfRows; r++) {
                for (int c = 0; c < noOfColumns; c++) {
                    xlRow = xlSheet.getRow(r);
                    xlCell = xlRow.getCell(c);

                    // Here we have complete excel data in an array -excelData-

                    excelData[r][c] = xlCell.getStringCellValue();

                    // System.out.println("row: " + r + " column: " + c);
                    // System.out.println(excelData[r][c]);
                }
            }

            // creating an array to store isExected column
            String[][] isExecuted = new String[noOfRows][1];

            for (int row = 1; row < noOfRows; row++) {
                // here column is always only one
                // so c=0

                // extracting a isExecuted column - and considering it as last
                // column in sheet
                // in your case it is not then - count the column position : use
                // position-1
                // ex: if column position is 7 then use 6 as below
                // isExecuted[row][0]= excelData[row][6];

                isExecuted[row][0] = excelData[row][noOfColumns - 1];

                if (isExecuted[row][0].equalsIgnoreCase("yes")) {

                    // accessing complete row -which isExecuted=Yes

                    // *********IMPORTANT*****
                    for (int col = 0; col < noOfColumns; col++) {
                        // prints all the rows where isExecuted column has Yes
                        System.out.println(excelData[row][col]);
                    }
                }

                // System.out.println(isExecuted[row][0]);

            }

        } catch (IOException e) {
            e.printStackTrace();
        }

    }

}

I used this Excel Data:

Test Case Name  Username    Password    Results IsExecute
APACHE_POI_TC   testuser_1  Test@123    Pass    Yes
APACHE_POI_TC   testuser_2  Test@124    Pass    No
APACHE_POI_TC   testuser_3  Test@125    Pass    Yes
APACHE_POI_TC   testuser_4  Test@126    Pass    Yes
APACHE_POI_TC   testuser_5  Test@127    Pass    No
APACHE_POI_TC   testuser_6  Test@128    Pass    Yes
