    Not directly. I believe that you have to force it through some intermediate data types first, like:

    Select @img = CAST(CAST(CAST(NtextColumn as nvarchar(max)) as varbinary(max)) as image)

    I gotta ask... why is the data stored this way? It's mostly "death by SQL" and now you want to compound the problem by converting it to the equivelent of hex?

    Sure... Barry is on the right track. Try that.

    I guess I don't need to tell you that the column information stored in the NTEXT column should really be normalized into multiple columns, huh? Good thing I'm not on your team... I'd be looking for that designer... with my favorite slingshot and an extra large bucket of pork chops... every waking minute, too! Man, they messed up that database! And they're making it worse!

    Please tell me that the reason for changing this field to binary is not a half-assed attempt at "encryption"...
