Use one CTE many times

by

A CTE is basically a disposable view. It only persists for a single statement, and then automatically disappears.

Your options include:

  • Redefine the CTE a second time. This is as simple as copy-paste from WITH... through the end of the definition to before your SET.

  • Put your results into a #temp table or a @table variable

  • Materialize the results into a real table and reference that

  • Alter slightly to just SELECT COUNT from your CTE:

.

SELECT @total = COUNT(*)
FROM Players p 
INNER JOIN Teams t 
    ON p.IdTeam=t.Id 
INNER JOIN Leagues l 
    ON l.Id=t.IdLeague
WHERE l.Id=@idleague
