【问题描述】：

我有一个表格，用于在一年中每个月为员工工资增加折扣或激励。此表包含一个字段，使用查找只能包含“折扣”或“动机”字样。

每个月我都可以添加多个折扣或激励措施，所以当我想在月底支付工资时，我希望将这些数据为每个员工分组在一行中。

这是包含当月折扣和激励的表格。表名是 Table1：

想要的查询结果：

【参考方案1】：

除了一个例外，以下查询提供了您想要的结果。例外情况是 Total_Discount 和 Total_Motivation 列未格式化为货币（这可能是不可取的，因为格式化的列将是字符串而不是数字）。

SELECT t.The_Year
     , t.The_Month
     , t.Emp_Num
     , Nz(DSum("Money_Amount","Table1","Discount_Motivation = 'Discount' AND The_Year = " & t.The_Year & " AND The_Month = " & t.The_Month & " AND Emp_Num = " & t.Emp_Num), 0) AS Total_Discount
     , ConcatRelated("Reason","Table1","Discount_Motivation = 'Discount' AND The_Year = " & t.The_Year & " AND The_Month = " & t.The_Month & " AND Emp_Num = " & t.Emp_Num) AS Discount_Reasons
     , Nz(DSum("Money_Amount","Table1","Discount_Motivation = 'Motivation' AND The_Year = " & t.The_Year & " AND The_Month = " & t.The_Month & " AND Emp_Num = " & t.Emp_Num), 0) AS Total_Motivation
     , ConcatRelated("Reason","Table1","Discount_Motivation = 'Motivation' AND The_Year = " & t.The_Year & " AND The_Month = " & t.The_Month & " AND Emp_Num = " & t.Emp_Num) AS Motivation_Reasons
FROM Table1 t
GROUP BY t.The_Year, t.Emp_Num, t.The_Month
ORDER BY t.The_Year, t.Emp_Num, t.The_Month
;

但是，如果确实需要这种格式，您可以简单地将这些列的行包装在 Format 函数中，并提供“货币”作为第二个参数：

SELECT t.The_Year
     , t.The_Month
     , t.Emp_Num
     , Format(Nz(DSum("Money_Amount","Table1","Discount_Motivation = 'Discount' AND The_Year = " & t.The_Year & " AND The_Month = " & t.The_Month & " AND Emp_Num = " & t.Emp_Num), 0), "Currency") AS Total_Discount
     , ConcatRelated("Reason","Table1","Discount_Motivation = 'Discount' AND The_Year = " & t.The_Year & " AND The_Month = " & t.The_Month & " AND Emp_Num = " & t.Emp_Num) AS Discount_Reasons
     , Format(Nz(DSum("Money_Amount","Table1","Discount_Motivation = 'Motivation' AND The_Year = " & t.The_Year & " AND The_Month = " & t.The_Month & " AND Emp_Num = " & t.Emp_Num), 0), "Currency") AS Total_Motivation
     , ConcatRelated("Reason","Table1","Discount_Motivation = 'Motivation' AND The_Year = " & t.The_Year & " AND The_Month = " & t.The_Month & " AND Emp_Num = " & t.Emp_Num) AS Motivation_Reasons
FROM Table1 t
GROUP BY t.The_Year, t.Emp_Num, t.The_Month
ORDER BY t.The_Year, t.Emp_Num, t.The_Month
;
