Hi Experts!

Thanks in advance for reading this. For SQL 2K.

There are two fields: description is char(60) and longdescription  as text.

What I want to do is select description only if longdescription is empty or no test in it.


  description = CASE WHEN (longdescription IS NULL) THEN description
                     ELSE longdescription

But it just select blank.


  description = CASE WHEN (longdescription = '') THEN description
                     ELSE longdescription
from svccode
where codeid = '00007'

But got this error msg:

Server: Msg 306, Level 16, State 1, Line 1
The text, ntext, and image data types cannot be compared or sorted, except when using IS NULL or LIKE operator.

Can you please help?
