ISNULL for a date to char conversion

[Roobmeister]

I am trying to return either a date in MMDDYYYY format, or a blank fixed width of 8 as part of a giant concatenation. For some reason, I am stuck on this point:

ISNULL(REPLACE(convert(char(8),mydate,101),'/',''),CONVERT(char(8),''))

"mydate" is a field of type datetime, but can sometimes be null.

The problem I am running into is that whether I write this as an "ISNULL" or a CASE statement, it doesn't seem to be able to return a char(8) blank when null.

I checked, and REPLACE(convert(char(8),mydate,101),'/','') does return a null..

Thoughts?

Thanks in advance.

Use the following

select ISNULL(REPLACE(convert(char(10),enddate,101),'/',''),CONVERT(char(8),'')) FROM assessments
