Question

我有需要格式化为百分比的性能数据（95％，100％，120％等），因此我可以排序和有条件地格式化。打开MS Access报告的属性窗口后，它将允许我更改直接从表格中提取的值的格式（常规数字，货币，百分比等），例如employee_id或shift 。但其他人，例如[6 wks ago]，[5 wks ago]和其他人，不允许我这样做。这是因为该字段是IIF()语句的结果吗？以下查询是我的原始查询：

SELECT 
D2s_roster_tbl.employee_id AS ID,
D2s_roster_tbl.employee_name AS Name, 
D2s_roster_tbl.position_desc AS [Position],
D2s_roster_tbl.adj_hire_dt AS [Hire DT], 
D2s_roster_tbl.shift_nbr AS Shift, 
D2s_roster_tbl.supervisor,
IIf([D2s_roster_tbl].[Position_desc] Like "*loader*",[trndLoaderPerformanceTbl_Crosstab].[11/09],[trndPerformanceQry_crosstab].[11/09]) AS [6 wks ago], 
IIf([D2s_roster_tbl].[Position_desc] Like "*loader*",[trndLoaderPerformanceTbl_Crosstab].[11/16],[trndPerformanceQry_crosstab].[11/16]) AS [5 wks ago], 
IIf([D2s_roster_tbl].[Position_desc] Like "*loader*",[trndLoaderPerformanceTbl_Crosstab].[11/23],[trndPerformanceQry_crosstab].[11/23]) AS [4 wks ago], 
IIf([D2s_roster_tbl].[Position_desc] Like "*loader*",[trndLoaderPerformanceTbl_Crosstab].[11/30],[trndPerformanceQry_crosstab].[11/30]) AS [3 wks ago], 
IIf([D2s_roster_tbl].[Position_desc] Like "*loader*",[trndLoaderPerformanceTbl_Crosstab].[12/07],[trndPerformanceQry_crosstab].[12/07]) AS [2 wks ago], 
IIf([D2s_roster_tbl].[Position_desc] Like "*loader*",[trndLoaderPerformanceTbl_Crosstab].[12/14],[trndPerformanceQry_crosstab].[12/14]) AS [Last wk], 

FROM 
((D2s_roster_tbl 
LEFT JOIN trndLoaderPerformanceTbl_Crosstab ON D2s_roster_tbl.employee_id = trndLoaderPerformanceTbl_Crosstab.employee_id) 
LEFT JOIN trndPerformanceQry_Crosstab ON D2s_roster_tbl.employee_id = trndPerformanceQry_Crosstab.employee_id)
LEFT JOIN trndPerfFormatPercent_Crosstab ON D2s_roster_tbl.employee_id = trndPerfFormatPercent_Crosstab.employee_id;

所以我认为好的，它不想格式化这种条件语句的结果。所以我将一系列IIF()s放在FROM语句中并直接选择这些值，如下所示：

SELECT
D2s_roster_tbl.employee_id AS ID,
D2s_roster_tbl.employee_name AS Name,
D2s_roster_tbl.position_desc AS [Position],
D2s_roster_tbl.adj_hire_dt AS [Hire DT],
D2s_roster_tbl.shift_nbr AS Shift,
D2s_roster_tbl.supervisor,
j.[6 wks ago],
j.[5 wks ago],
j.[4 wks ago],
j.[3 wks ago],
j.[2 wks ago],
j.[Last wk]

FROM
((D2s_roster_tbl
LEFT JOIN trndLoaderPerformanceTbl_Crosstab ON D2s_roster_tbl.employee_id = trndLoaderPerformanceTbl_Crosstab.employee_id)
LEFT JOIN trndPerformanceQry_Crosstab ON D2s_roster_tbl.employee_id = trndPerformanceQry_Crosstab.employee_id)
LEFT JOIN (SELECT
    d2s_roster_tbl.employee_id,
    IIf([D2s_roster_tbl].[Position_desc] Like "*loader*",[trndLoaderPerformanceTbl_Crosstab].[11/09],[trndPerformanceQry_crosstab].[11/09]) AS [6 wks ago], 
    IIf([D2s_roster_tbl].[Position_desc] Like "*loader*",[trndLoaderPerformanceTbl_Crosstab].[11/16],[trndPerformanceQry_crosstab].[11/16]) AS [5 wks ago],
    IIf([D2s_roster_tbl].[Position_desc] Like "*loader*",[trndLoaderPerformanceTbl_Crosstab].[11/23],[trndPerformanceQry_crosstab].[11/23]) AS [4 wks ago], 
    IIf([D2s_roster_tbl].[Position_desc] Like "*loader*",[trndLoaderPerformanceTbl_Crosstab].[11/30],[trndPerformanceQry_crosstab].[11/30]) AS [3 wks ago], 
    IIf([D2s_roster_tbl].[Position_desc] Like "*loader*",[trndLoaderPerformanceTbl_Crosstab].[12/07],[trndPerformanceQry_crosstab].[12/07]) AS [2 wks ago], 
    IIf([D2s_roster_tbl].[Position_desc] Like "*loader*",[trndLoaderPerformanceTbl_Crosstab].[12/14],[trndPerformanceQry_crosstab].[12/14]) AS [Last wk]

   FROM 
   ((D2s_roster_tbl 
   LEFT JOIN trndLoaderPerformanceTbl_Crosstab ON D2s_roster_tbl.employee_id = trndLoaderPerformanceTbl_Crosstab.employee_id) 
   LEFT JOIN trndPerformanceQry_Crosstab ON D2s_roster_tbl.employee_id = trndPerformanceQry_Crosstab.employee_id))  AS J ON d2s_roster_tbl.employee_id = j.employee_id;

它也不允许我格式化此查询中的[n wks ago]列。我的原始效果表有4列：employee_id，week_ending_dt，goal_hrs和hrs_worked。这个数据是过去6周的，因此我创建了交叉表查询，以便为每周提供不同的列（我们使用它来查看性能是如何每周一周的趋势）。加载程序性能与其他程序的性能分开存储，因此这就是我在查询中需要IIF()的原因。是否有某种方法可以获取此信息，将最终性能值保持为可以更改格式的数值？

This here是我原来的问题，但我缺乏特异性意味着这个答案是不可行的。谢谢！

事实证明，提供交叉表的查询具有以下性能表达式：

IIf([d2s_performance_tbl].[hrs_worked]=0,"", Round(([d2s_performance_tbl].[goal_hrs]/[d2s_performance_tbl].[hrs_worked]),2))。

删除IIF()只留下

Round(([d2s_performance_tbl].[goal_hrs]/[d2s_performance_tbl].[hrs_worked]),2)

将值保留为数字，这些数字会一直显示在报告中，允许我更改为百分比和排序以及所有其他有趣的数字值。

为什么我不能在MS Access报告中更改数字字段的格式？
