Returning rows selected in with statement - sql

Question

I have a sql statement looking something like this
WITH [ResultPage] AS (
SELECT sub.id as id, ROW_NUMBER() OVER (ORDER BY [TAG].[Name] ASC, [TAG].[ID] ASC) As [RowID], [sub].[hasPending]
FROM
(SELECT t.[ID], p.[TagID],(CASE WHEN p.[TagID] is not null THEN 1 ELSE 0 END) AS [hasPending]
FROM [Tag] AS t
full outer Join [TagPending] AS p On t.[ID] = p.[TagID]
GROUP BY t.[ID],p.[TagID]
) AS [sub]
inner Join [Tag] On [Tag].[ID] = sub.[ID]
)
SELECT [ResultPage].[RowID], [Tag].[ID] As [Tag^ID], [Tag].[Name] As [Tag^Name]
FROM [ResultPage]
INNER JOIN [Tag] ON ([Tag].[ID] = [ResultPage].[TagID])
INNER JOIN [TagPending] ON ([TagPending].[TagID] = [KbResultPage].[TagID])
WHERE (([ResultPage].[RowID] BETWEEN 1 AND 50)
)
ORDER BY [ResultPage].[RowID] ASC
As can be seen, the select max returns 50 rows at a time, however I need to know the total number of rows found in the WITH statement. I could run it again with just a count, however it could be nice if there were a way to get both in one go.

You can use the COUNT(*) OVER() in the WITH statement
WITH [ResultPage] AS (
SELECT COUNT(*) OVER() AS totalRows,
sub.id as id, ROW_NUMBER() OVER (ORDER BY [TAG].[Name] ASC, [TAG].[ID] ASC) As [RowID], [sub].[hasPending]
FROM
(SELECT t.[ID], p.[TagID],(CASE WHEN p.[TagID] is not null THEN 1 ELSE 0 END) AS [hasPending]
FROM [Tag] AS t
full outer Join [TagPending] AS p On t.[ID] = p.[TagID]
GROUP BY t.[ID],p.[TagID]
) AS [sub]
inner Join [Tag] On [Tag].[ID] = sub.[ID]
)
SELECT
[ResultPage].totalRows,
[ResultPage].[RowID], [Tag].[ID] As [Tag^ID], [Tag].[Name] As [Tag^Name]
FROM [ResultPage]
INNER JOIN [Tag] ON ([Tag].[ID] = [ResultPage].[TagID])
INNER JOIN [TagPending] ON ([TagPending].[TagID] = [KbResultPage].[TagID])
WHERE ([ResultPage].[RowID] BETWEEN 1 AND 50)
ORDER BY [ResultPage].[RowID] ASC
