Coldfusion CF在数据库查询中获取列的总和

我正在尝试使用ColdFusion和MS Sql计算列的总数

有人能告诉我我忽略了什么吗？我对位置总数的合计不是对该列求和，而是出于某种原因，只取该列中的最后一个数字。我哪里做错了

<cfset result = {} /> 
<cftry> 
    <cfquery datasource="#application.dsn#" name="GetLocationInfo">
        SELECT *
        FROM cl_checklists
    </cfquery>

    <cfcatch type="any"> 
        <cfset result.error = CFCATCH.message > 
        <cfset result.detail = CFCATCH.detail > 
    </cfcatch> 
</cftry> 

<table border="1" id="Checklist_Stats">
    <thead>
        <th><strong>Location</strong></th>
        <th><strong>Percent of Total Checklists</strong></th>
        <th><strong>Location Total</strong></th> 
    </thead>
    <tbody>
    <cfquery name="allLocCode" dbtype="query">
        SELECT DISTINCT trans_location, COUNT(*) AS locationCount FROM GetLocationInfo GROUP BY trans_location ORDER BY trans_location 
    </cfquery>
     <cfloop query="allLocCode">
      <cfset thisLocationName = trim(allLocCode.trans_location) />

      <cfquery name="allLocCodeForLocationQry" dbtype="query">
          SELECT trans_location,count(trans_location) AS locCntr FROM GetLocationInfo WHERE trans_location='#thisLocationName#' GROUP BY trans_location ORDER BY trans_location
      </cfquery>
        <cfset columnSum = ArraySum(allLocCodeForLocationQry['locCntr'])>
      <cfoutput query="allLocCodeForLocationQry">
      <tr>
        <td><strong>#thisLocationName#</strong></td>
        <td>#NumberFormat((allLocCodeForLocationQry.locCntr/allLocCode.locationCount) * 100, '9.99')#%</td>
        <td>#allLocCodeForLocationQry.locCntr#</td>
      </tr>
     </cfoutput>
     </cfloop>
     <tr>
      <td><strong>Total</strong></td>
      <td></td>
      <td><cfoutput>#numberFormat(columnSum)#</cfoutput></td>
    </tr>
    </tbody>
    <!--- Total of All Sum of each column --->
</table>

试试这个

每次循环查询时，都会将一个值（位置计数）附加到列表中

大概是这样的：

<cfset myList = "">
<cfloop query="allLocCode">
<cfset myList = ListAppend(myList, locationCount, ',')>

<!---your other logic--->
</cfloop>

---

最后的答案是121。

columnSum变量在cfloop中。将该行放在cfloop的前面或后面，您将得到总计334行。

既然这是sql server，为什么不利用它使用with关键字的能力呢？总体思路是：

with totalRecords as 
(select count(*) records
from etc),

groupedRecords as
(select someField, count(*) recordsForField
from etc
group by someField)

select whatevever
, (groupedRecords.recordsForField / totalRecords.records) * 100 percentage
from someTables
join groupedRecords on groupedRecords.someField = someTable.someField

where totalRecords.records > 0

---

然后您只需输出查询结果。

看起来您知道如何在SQL中使用COUNT。。。你试过SUM吗？我想也许我看错了。我的第一反应总是在使用ColdFusion变量之前执行数学运算并修改查询本身中的数据，但这在这里并不谨慎。看看我下面的答案-我想它对你有用。如果你需要保存一个列表，把它放在一个数组中，以后再转换成一个列表。我想你是对的。抢手货我很累，只是想把逻辑拼凑起来。

<cfoutput>#listSum(myList)#</cfoutput>

with totalRecords as 
(select count(*) records
from etc),

groupedRecords as
(select someField, count(*) recordsForField
from etc
group by someField)

select whatevever
, (groupedRecords.recordsForField / totalRecords.records) * 100 percentage
from someTables
join groupedRecords on groupedRecords.someField = someTable.someField

where totalRecords.records > 0
