How come you don't want to use UNION? It is possible to write a query that does this as a set without UNION but it is very contorted.

Is a variable ok?

DECLARE@string AS NVARCHAR(MAX)

SELECT TOP 5

@string = COALESCE(@string, N'MY DATABASE TABLE: ') + CHAR(10) + name

FROM sys.tables

ORDER BY

name DESC

SELECT @string

And here it is. Nasty, eh?

SELECT TOP 6

the_output = CASE

WHEN tables.name = yucky.first_table THEN

N'MY DATABASE TABLE: '

ELSE

name

END

FROM sys.tables

CROSS JOIN

(

SELECT first_table = MIN(name)

FROM sys.tables

) AS yucky

ORDER BY

CASE

WHEN tables.name = yucky.first_table THEN

CHAR(255)

ELSE

name

END DESC

How about an outer join from a tally table (where row = required number of rows+1) to a cte which has a rownumber function.

The you simply need to isnull the non-joined tally table row.

Probably not what you're looking for, but how's this?

Select top 5 'MY DATABASE TABLE: ' = name

from sysobjects

where xtype = 'u'

order by 1 desc

If you can't explain to another person how the code that you're copying from the internet works, then DON'T USE IT on a production system! After all, you will be the one supporting it!

Ummm.... Nope... you didn't. Look again... a bit more carefully this time. 😉

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
