:setvar Instance SUBSTRING(@@SERVERNAME,7,3)
:setvar FolderPath "\\Here\there\where"
I have two sqlcmd variables that i need to concatenate and store the values in the third variable and use that variable in a query.
somthing like
:setvar FullName $(FolderPath)+$(FolderPath)
how can this be done, i tried a couple methods- don't seem to work- any idea?

No need to concatenate the sqlcmd scripting variables, just do the concatenation in the query.

😎

:setvar PartOne 'first_'

:setvar PartTwo 'second'

go

select char(39) + $(PartOne) + $(PartTwo) + char(39) as full_path

go

Results

full_path

--------------

'first_second'

Forgot to answer the question:-D

It's not possible to programmatically set or concatenate the variables without writing to a file.

Based on what Eirikur posted above, why not build a stored procedure that does this work and execute the stored procedure from SQLCmd, instead?

Also, why are you using SQLCmd? What is it that you're actually trying to do overall? I ask because there may be better methods.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
