I am trying to generate a sequence varchar text type, but I do not want to have to create another column to get the id to format it and insert it I want to generate it in the same column, help
create table tbl (
Id int identity not null,
CusId as 'CUS' + format(Id, '00000'),
-- ...
)
Believe the only viable solution is using 2 columns as you mentioned, and discussed here:
Autoincrement of primary key column with varchar datatype in it
Have not seen it achieved in a single column on its own.
