SQL Server order by cases - sql

Question

I am using SQL Server 2012.
Here is my query, I want the ordering in this order and not alphabetical.
Here is the order I want them in :
Foreign,
Out of State,
Texas,
Unknown,
Total Enrollment
I used order by cases, but I am getting an error:
Incorrect syntax near '5'
How do I fix it?
Query :
declare #Term int = 20172;
select
[Category], [Last_Term], [Current_Term], [#Change], [%Change]
from
(select
[Category],
cast(round(((cast(y.Last_Term as float)) * 1), 2) as varchar(10)) as 'Last_Term',
cast(round(((cast(y.Current_Term as float)) * 1), 2) as varchar(10)) as 'Current_Term',
cast(round(((cast(y.Current_Term as float) -
cast(y.Last_Term as float)) * 1), 2) as varchar(10)) as '#Change',
cast(round((((cast(y.Current_Term as float) -
cast(y.Last_Term as float)) /
(cast(y.Last_Term as float))) * 100), 2) as varchar(10)) + '%' as '%Change'
from
(select
Category,
Case
when year = substring(CAST (#Term- 10 as Varchar(10)),1,4)
then 'Current_Term'
when year = substring(CAST (#Term - 20 as Varchar(10)),1,4)
then 'Last_Term'
End As ACAD_YEAR,
a.enroll
from
(select
case
when dh.HOME = 'F'
then 'Foreign'
when dh.HOME = 'O'
then 'Out of State'
when dh.Home = 'I'
then 'texas'
when dh.Home = 'U'
then 'UnKnown'
end as Category,
(CONVERT(INT, SUBSTRING(ACADEMIC_PERIOD, 1, 4))) - 1 as year,
count(*) as enroll
from
[IR_DW].[dbo].[dw_enrollment_F] d

case
when a.[Category] = 'Foreign' then 1
when a.[Category] = 'Out of State' then 2
when a.[Category] = 'Texas' then 3
when a.[Category] = 'Unknown' then 4

Answer 1

You are missing and END though you are missing the 5 case as well...
when a.[Category] = 'Total Enrollment' then 5
ORDER BY
case when a.[Category] = 'Foreign' then 1
when a.[Category] = 'Out of State' then 2
when a.[Category] = 'Texas' then 3
when a.[Category] = 'Unknown' then 4
when a.[Category] = 'Total Enrollment' then 5 --added this
else 6 --catch all to make anything that fell outside of these categories unsorted afterwards
end --added here
