Hi,
This should be a pretty simple task for a SQL guru. Its just a little complicated for me with the nesting.
I have a table consisting of the data I need to populate another table. However in the target table the data needs to be split into multiple rows per "item" which has a unique identifier.

I need a query that will basically take each column of the source table row and add it to a separate row in the TARGET table. I have set up a few rows of each below.The data in the TARGET table is always the same for each item id. So the query needs to create the SET of rows for EACH of the line items in the SOURCE table.
SOURCE:

[ID]    [service]     [time]    [price]
59	Golden  	30	45.00
60	Sparkle 	30	45.00

TARGET

[id]	AllowCancellations	True
[id]	AllowRescheduling	True
[id]	AppointmentDuration	[time]
[id]	AppointmentDurationMax	[time]
[id]	AppointmentInterval	[time]
[id]	CancellationFee	        0.00
[id]	DaysAhead	         30
[id]	MaxAppointments  	4
[id]	MinTimeAhead	       00:00:00
[id]	ReschedulingFee	        0.00
[id]	SchedulingFee	        [Price]

Hi,
if you source table is not changing use the union to solve you problem

query:

Union
Select [ID]     [time]  
Union
Select [ID]     [price]
...

LIKE this create a subquery / table for the data to be added to target
and then cross join that to the source table to generate the rows to be inserted...
INSERT INTO [tARGET]
 ([ID],[nAME],[vALUE])
select s.[id],X.NAME
     ,CASE X.TYPE
           WHEN 'v' THEN X.VALUE
           WHEN 'c' 
           tHEN cASE x.vALUE 
                     WHEN 'tIME' THEN CONVERT(VARCHAR(10),S.TIME)
                     WHEN 'PRICE' THEN CONVERT(VARCHAR(20),S.PRICE)
                     END
           END        
           
 from [SOURCE] AS s
 CROSS jOIN 
(
select 'AllowCancellations' as Name,'V' as type,'True' as Value
union all select 'AllowRescheduling','V','True'
union all select 'AppointmentDuration','C','time'
union all select 'AppointmentDurationMax','C','time'
union all select 'AppointmentInterval','V','time'
union all select 'CancellationFee','V','0.00'
union all select 'DaysAhead','V','30'
union all select 'MaxAppointments','V','4'
union all select 'MinTimeAhead','V','00:00:00'
union all select 'ReschedulingFee','V','0.00'
union all select 'SchedulingFee','C','Price'
) as x
