I would expect fail for the same reason that the UPDATE failed. I ran:
CREATE TABLE textie (id int NOT NULL,
thetext text NULL)
go
INSERT textie(id, thetext)
VALUES (1, replicate('This is the original text', 2000))
go
SELECT id, thetext + '(Stylized)' AS ggg INTO newtextie FROM textie
go
SELECT datalength(thetext) FROM textie
SELECT datalength(thetext) FROM newtextie
go
DROP TABLE textie, newtextie
And I got:
(1 row(s) affected)
Msg 402, Level 16, State 1, Line 1
The data types text and varchar are incompatible in the add operator.
