So the issue is, if somebody does this ...
$select->from('table_name');
$result = $sql->query($select);
... then it fails, because they didn't specify any cols to retrieve.
Although it seems harmless, I don't think we should set a default for that. My fear is that it could get in the way of some kinds of rare but necessary queries, but I don't have any proof for that.
We can point out in the documentation how to debug that kind of problem, though. Would that help?

Can we throw an exception stating the reason, when cols is empty ?

I get the idea there may be times when cols is supposed to be empty, but I don't know. Is the error not obvious when it occurs?

This was what I was trying earlier
$select = new Aura\Sql\Select($sql);
$select->from('posts');
$result = $sql->fetchOne($select);
var_export($result);
When column is not given error is
SELECT
PHP Fatal error: Uncaught exception 'Aura\Autoload\Exception\NotReadable' with message 'Aura\Sql\Select

Obviously nothing there to figure out right ?
When table name is not given , error below
$select = new Aura\Sql\Select($sql);
$select->cols(array('id', 'author_id', 'title', 'body'));
$result = $sql->fetchOne($select);
var_export($result);
Which I got the errors as below
PHP Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42S22]: Column not found: 1054 Unknown column 'id' in 'field list'' in /media/Linux/aurasystem/package/Aura.Sql/src/Aura/Sql/Profiler.php:82

I don't think this is that big a deal, but even so, what do you suggest as the remedy?

What my suggestion is if no fields or table name found lets throw a meaningful exception

Technically, you don't always need a table name. For example, you can issue SELECT NOW() and it works just fine.
After thinking about this for a long time, I realize I'd rather not get into checking SQL syntax in the PHP; if the developer gets it wrong, he'll be notified by the database. PDO will throw an exception with everything you need to diagnose the failure.
