Hi kranthi88,

Normally we use JavaScript as the front-end application while using C#/C++ component as a controller to communicate with the sqlite. Here is a Github link for you to know how to use JavaScript to communite with a sqlite database, by using the sample code below you will be able to do so.

var dbPath = Windows.Storage.ApplicationData.current.localFolder.path + '\\db.sqlite';
SQLite3JS.openAsync(dbPath)
.then(function (db) {
  return db.runAsync('CREATE TABLE Item (name TEXT, price REAL, id INT PRIMARY KEY)')
  .then(function () {
    return db.runAsync('INSERT INTO Item (name, price, id) VALUES (?, ?, ?)', ['Mango', 4.6, 123]);
  })
  .then(function () {
    return db.eachAsync('SELECT * FROM Item', function (row) {
      console.log('Get a ' + row.name + ' for $' + row.price);
    });
  })
  .then(function () {
    db.close();
  });
});

Best Regards,

Hi Kranthi88,

You can follow the steps to make SQLite3JS works fine for you:

1, Add the SQLite3 C++ project (SQLite3\SQLite3.vcxproj) to your solution.

2, Add a reference to it from the JavaScript project in your solution:

Right-click on the JS project in solution explorer, Click add reference, Select solution, Add the checkmark for SQLite3 project.

And make sure that you add the C++ project to the solution, not to your JavaScript project. It is added correctly if there is a little triangle left to SQLite3 in the solution explorer.
