Question

在这里，我试图计算满足条件的记录数量，以便我可以在应用程序的磁贴中显示总数。但是我没有成功，你能告诉我如何计算以及把它放在哪里。

(
  @P_FACILITY_KEY_CSV VARCHAR(MAX)
, @DATEFROM DATETIME 
, @DATETHRU DATETIME
, @P_TOTALS NUMERIC(1, 0)
)

您是否只希望查询中的其他列是返回的所有记录的COUNT？

SELECT COUNT(1) OVER () Total,
       .. <all your other columns> ..

或者如果您可以将其作为SP返回值返回，那么

RETURN @@ROWCOUNT

最后，假设您显示的内容（IF / SELECT）是SP的结尾。

需要在查询中计数
