我试图找到总金额为REPORT_STATUS IN REPORT表，但我不知道如何。我只能算作REPORT_STATUS，但不能按月计算。如何在php中查找总金额FILTERED BY month？

$count = "SELECT 
(SELECT COUNT(REPORT_STATUS) FROM REPORT WHERE REPORT_STATUS = 1) as 
NumberOfReport1, (SELECT COUNT(REPORT_STATUS) FROM REPORT WHERE REPORT_STATUS = 2) 
as NumberOfAReport2,(SELECT COUNT(REPORT_STATUS) FROM REPORT WHERE REPORT_STATUS = 3) 
as NumberOfReport3,(SELECT COUNT(REPORT_STATUS) FROM REPORT WHERE REPORT_STATUS = 4) 
as NumberOfReport4 "; 

$result1= mysql_query($count);

GROUP BY是你的朋友。事情是这样的：

SELECT month, COUNT(REPORT_STATUS) FROM REPORT WHERE REPORT_STATUS = 1 GROUP BY month

你还不能做什么？你作为结果得到什么？你想要什么？有错误吗？ ...请处理你的问题。 – PiTheNumber 2011-12-21 08:51:38
