Imo this is a guessing puzzle unless there's more of an explanation.  What are the rules to apply here?  Why not remove all of the dashes '-' and then concatenate...

What's the new question?

By default SQL Server performs integer division on integers which means decimal remainders are truncated.  The DB Engine switches  to floating point math if the denominator of a fraction is...

Sorry  not able to replicate the issue.  The OP code relies on implicit conversion between INT and NVARCHAR which generally works but is an error prone (and awful for the...

Jeff's code seems to generate primary keys and produces the correct output afaik.  Creating foreign keys should be straightforward for the OP.  The split could be accomplished with OPENJSON without...

Why does this make sense?  CONVERT using style 2 seems to convert to text and removes the leading '0x'

select Modelnameid origignal

A good first step could be to run this code

select datepart(weekday, cast(getdate()+nums.n as date)) day_of_week_number, 
       datename(weekday, cast(getdate()+nums.n as date)) day_of_week
