                        Your constraint is actually a column constraint.  If you want it to be a table constraint you need to precede it with a comma.  See the BNF in BOL for Create Table. 
I know that it seems a unique constraint could only be a Table level constraint but the syntax clearly allows it to be defined as either a table or column constraint. 
And just to add to confusion both forms create a table level constraint object [image] . 
I imagine that SQL Prompt just treats your format is as part of the column definintion.  Try it by adding a perceding comma and see how the format changes.
