Question

我使用phpgrid显示查询数据，然后通过页面上的表单选择进行过滤。这个工作正常，直到我添加汇总到查询总和列，我想知道是否有任何其他方法来汇总这些列（其中12个）？

这并不能告诉我无法执行查询。未知专栏＆＃39; i.signedupdate＆＃39;在＆＃39; where子句

SELECT * FROM
  (SELECT IFNULL(c.Adviser, 'GRAND TOTAL') AS Adviser,
  Sum(Month(i.SignedUpDate) = 1) As Jan,
  Sum(Month(i.SignedUpDate) = 2) As Feb,
  Sum(Month(i.SignedUpDate) = 3) As Mar,
  Sum(Month(i.SignedUpDate) = 4) As Apr,
  Sum(Month(i.SignedUpDate) = 5) As May,
  Sum(Month(i.SignedUpDate) = 6) As Jun,
  Sum(Month(i.SignedUpDate) = 7) As Jul,
  Sum(Month(i.SignedUpDate) = 8) As Aug,
  Sum(Month(i.SignedUpDate) = 9) As Sept,
  Sum(Month(i.SignedUpDate) = 10) As Oct,
  Sum(Month(i.SignedUpDate) = 11) As Nov,
  Sum(Month(i.SignedUpDate) = 12) As Dece,
  i.id,
  Count(i.id) As Total
    From
  tbl_lead i Inner Join
  tbl_clients c On i.client_id = c.client_id
Group By
    c.Adviser with rollup) As t

这样可行，我可以选择年份，但没有列摘要

SELECT * FROM
  c.Adviser AS Adviser,
  Sum(Month(i.SignedUpDate) = 1) As Jan,
  Sum(Month(i.SignedUpDate) = 2) As Feb,
  Sum(Month(i.SignedUpDate) = 3) As Mar,
  Sum(Month(i.SignedUpDate) = 4) As Apr,
  Sum(Month(i.SignedUpDate) = 5) As May,
  Sum(Month(i.SignedUpDate) = 6) As Jun,
  Sum(Month(i.SignedUpDate) = 7) As Jul,
  Sum(Month(i.SignedUpDate) = 8) As Aug,
  Sum(Month(i.SignedUpDate) = 9) As Sept,
  Sum(Month(i.SignedUpDate) = 10) As Oct,
  Sum(Month(i.SignedUpDate) = 11) As Nov,
  Sum(Month(i.SignedUpDate) = 12) As Dece,
  i.id,
  Count(i.id) As Total
    From
  tbl_lead i Inner Join
  tbl_clients c On i.client_id = c.client_id
Group By
    c.Adviser

如果我只是删除子查询并将＆＃39;与汇总＆＃39;它警告我＆amp;的错误使用顺序汇总？

任何想法都非常感激，只需要总结所有这些列

您应该使用建议here的SQL视图。

建议使用Sql视图   当Sql很复杂时。它本质上是一个虚拟表，其中   它被定义为带有连接的SQL SELECT查询。因为一个数据库   view类似于数据库表，它由行和组成   列，因此您可以像实际数据库表一样查询数据。

另一个好处是您可以重复使用此视图。另外，如果   如果需要，将来使用视图而不是连接表   要更改列，您可以轻松地执行此操作，只需要更改   Sql视图。

mysql总计不使用汇总
