何解 with

error:

Incorrect syntax near the keyword 'with'. If this statement is a common table expression, an xmlnamespaces clause or a change tracking context clause, the previous statement must be terminated with a semicolon.

第一種種解決方式：

;with XMLNAMESPACES('http://schemas.myself.com/SomeSchema' as ns)
, t as

第二種種解決方式：

; with t (staffid, sheetno)
as
   (select distinct staffid
    , (case @tform WHEN 'B' THEN sheetno else (ROW_NUMBER() OVER (order by staffid asc)) end
              ) as sheetno
               from tableXXX )
