Question

How would this INSERT statement be rewritten without the subquery, so it no longer results in the error “Subqueries are not allowed in this context. Only scalar expressions are allowed”?

INSERT INTO FUNCTIONAL_AREA (
  FUNCTIONAL_AREA_UUID
  ,FUNCTIONAL_CATEGORY_UUID  
  ,CREATE_DATETIME 
  ,CREATE_USER 
  ,LUPDATE_DATETIME
  ,LUPDATE_USER 
  ,DESCRIPTION
  ,ITEM_CODE
  ,IS_ACTIVE 
) VALUES ( 
 NEWID()  
 ,(select functional_category_uuid from functional_category where description = 'ADLs')
 ,GETDATE()
 ,'11111111-1111-1111-1111-111111111111'
 ,GETDATE()
 ,'11111111-1111-1111-1111-111111111111'
 ,'Bathing - Ability' 
 ,1081
 ,1)

Thank you!

INSERT INTO FUNCTIONAL_AREA (
  FUNCTIONAL_AREA_UUID
  ,FUNCTIONAL_CATEGORY_UUID  
  ,CREATE_DATETIME 
  ,CREATE_USER 
  ,LUPDATE_DATETIME
  ,LUPDATE_USER 
  ,DESCRIPTION
  ,ITEM_CODE
  ,IS_ACTIVE

select NEWID()  
 ,functional_category_uuid 
 ,GETDATE()
 ,'11111111-1111-1111-1111-111111111111'
 ,GETDATE()
 ,'11111111-1111-1111-1111-111111111111'
 ,'Bathing - Ability'

from functional_category 
where description = 'ADLs'

EDIT Adding:

If you only want one row inserted and you care about which row is selected from functional_category, then either narrow the where clause so only one row comes back, or use an order by and top 1:

INSERT INTO FUNCTIONAL_AREA (
  FUNCTIONAL_AREA_UUID
  ,FUNCTIONAL_CATEGORY_UUID  
  ,CREATE_DATETIME 
  ,CREATE_USER 
  ,LUPDATE_DATETIME
  ,LUPDATE_USER 
  ,DESCRIPTION
  ,ITEM_CODE
  ,IS_ACTIVE 
)
select top 1 NEWID()  
 ,functional_category_uuid 
 ,GETDATE()
 ,'11111111-1111-1111-1111-111111111111'
 ,GETDATE()
 ,'11111111-1111-1111-1111-111111111111'
 ,'Bathing - Ability' 
 ,1081

from functional_category 
where description = 'ADLs'
order by <criteria that causes the correct row to be first>
