Question

I am semi-new to C# but in particular using Sqlite within C#, currently I have a SQlite DB setup fine in terms of it connects with the application well I am running windows form application and I have bound a table within the database to a datagrid view.

This is all fine I have a function setup to run queries where i pass the SQL statement as a string to the function and it runs it as a query.

I was wandering how I do I get a result back from the query I know obviosuly it will be somthing like

private string QueryResult(string query){
    connect
    run query
    read query 
    return result
}

All th examples I have seen use Sqlreader but I can’t seem to get it work, I am really used to using PHP with SQL and that seems so much simpler than using it in C# can someone explain or point out somewhere I might be able to find a tutuorial or function that you can run any query in by passing it as a string and getting the result returned pretty simply? The results I need wont be arrays or huge things I am only looking to return 1 word strings or numbers at a time so I don’t need anything complicated.

Please help me out I spent about 4 hours reading about this stuff last night and didn’t seem to get anywhere.

Try this, maybe it will help you:

public string QueryResult(string query)
{
    string result = "";
    SQLiteConnection sqlite = new SQLiteConnection("Data Source=/path/to/file.db");
    try
    {
        sqlite.Open();  //Initiate connection to the db
        SQLiteCommand cmd = sqlite.CreateCommand();
        cmd.CommandText = query;  //set the passed query
        result = cmd.ExecuteScalar().ToString();
    }
    finally
    {
        sqlite.Close();
    }
    return result;
}
