CAST(<source column>) as NVarchar(1))

CAST(('0' as franchiseevendaccount) as NVARCHAR(1))

---

Incorrect syntax near the keyword 'as'.

Well, yes that's going to give an error. Aliases go after the column definition, not in the middle of a function.

CAST('0' as NVARCHAR(1)) as Franchiseevendaccount

Or, you could skip the cast altogether and define it as a unicode string from the start

N'0' as Franchiseevendaccount
