For sqlite you need to add org.xerial:sqlite-jdbc as a dependency in your build.gradle file.

import java.sql.DriverManager

// Create a connection to the database
val url = "jdbc:sqlite:myDatabase.db"
val connection = DriverManager.getConnection(url)

// Create a statement
val statement = connection.createStatement()

// Execute a SELECT query
val resultSet = statement.executeQuery("SELECT * FROM Employee")

// Iterate through the results
while (resultSet.next()) {
    val id = resultSet.getInt("id")
    val name = resultSet.getString("name")
    val age = resultSet.getInt("age")
    println("id: $id, name: $name, age: $age")
}

// Close the result set, statement, and connection
resultSet.close()
statement.close()
connection.close()

In this example, executeQuery() method is used to execute the SELECT query and it returns a ResultSet object which can be used to iterate through the results. The next() method of the ResultSet is used to move the cursor to the next row and the getXXX() methods are used to retrieve the values of the columns from the current row.
