SQL Server Array on Declare statements via query

I am trying to do something like

DECLARE @ID int = CHANGEME,
        @StartDate  datetime = '2023-09-02 04:00',
        @FinishDate datetime = '2023-09-03 04:00'

But this only lets me run this report per id, I have a list of IDs from another table that i can pull by a query

select id
form table
where tablename like '$tryme$'

So is there a way that I can run the report per ID again and again until we've run the list finished?

I saw that this is the way to write multiple/array in the statement

DECLARE @SITEIDS TABLE(siteid int)
Insert into @SITEIDS
values ('R00013'), ('R00028')

but this looks like it's hard coded ids.

I'm trying to get a report with

DECLARE @ID int = 1,
DECLARE @ID int = 12,
DECLARE @ID int = 123,

sql-server

Something like the following should allow you to do exactly what you are asking.

DECLARE @id int;
SELECT @id = MIN(id) FROM table where tablename like '$tryme$'
WHILE @id IS NOT NULL
BEGIN
   -- Code to run your report here 
   SELECT @id = MIN(id) FROM table WHERE tablename like '$tryme$' AND id > @id
END

You put the MIN(id) into your @id variable, process the report for that value, then grab the next MIN(id) that's greater than the one you just processed, and keep looping until no more id value is found.

DECLARE @StartDate datetime = '2023-09-02 04:00'
DECLARE @FinishDate datetime = '2023-09-03 04:00'
CREATE TABLE #TempIDs (ID int)
INSERT INTO #TempIDs (ID)
    SELECT id FROM YourTable WHERE tablename LIKE '$tryme$'
DECLARE @CurrentID int
SELECT TOP 1 @CurrentID = ID FROM #TempIDs
-- Loop through the IDs and run the report for each ID
WHILE @CurrentID IS NOT NULL
BEGIN
    -- Execute your report here using @CurrentID
    -- Delete the processed ID from the temporary table
    DELETE FROM #TempIDs WHERE ID = @CurrentID
    -- Get the next ID
    SELECT TOP 1 @CurrentID = ID FROM #TempIDs
END
DROP TABLE #TempIDs
