The table contains a single row with a single column that contains a string.
Like this explanation. Much better than my attempt.
What the outer select sees in its from clause is an ["unnamed-table"]
that [contains one row containing 'tab1'].
Thank you for pushing this point.
The point I was
The table contains a single row with a single column that contains a string.
That doesn't make it a string. It's still a table. When you say "select ...
from table" it doesn't matter where the table came from, it's still an
operation on a table. You are not performing "select ... from 'tab1';",
Yes, correct.
But the contents of the returned table are not objects, but merely values.
In this case the returned table contains a single string value
which happens to be the name of a table, but it is not the table.
Or do I get this wrong?

Select returns a table, not a name or a
I thought it was because what SQL returns is a value (in this case a
string) and not an object?
The string value might be the same as the name of an object, but is not
the object.
