我在Power Query中遇到动态参数问题。有代码：

发生错误：

Expression.Error：Nãoconseguimosaplicar o operador＆lt; aos tipos 编号e日期。事件详细信息：操作者= LT; 左= 42795 右= 01/06/2007

我该如何解决？

注意：MY PARAMETER（2017年3月1日）以文字形式出现。

Answer 1

虽然我不会阅读西班牙文，但看起来它表示您无法将数字和日期与<运算符进行比较。

顺便说一下，首先将参数转换为正确的类型是很好的做法：

InicioExec_Valor = Date.From(Parametro{0}[Valor]),
FimExec_Valor = Date.From(Parametro{1}[Valor]),`

试试这个。

如果它不起作用，请通过逐个单击来确定生成错误的步骤。

我想知道更多。为什么要将Fim_Exec转换为nvarchar然后转换为日期？
1. #(lf)CONVERT(nvarchar(10), o.dt_encos_oficina, 103) AS Fim_Exec
2. {"Fim_Exec", type date},
为什么不使用Fim_Exec = CAST(o.dt_encos_oficina as date)？（或datetime，具体取决于SQL Server版本）查询？

同样适用于其他专栏。

接下来，除非绝对必要，否则最好不要使用本机查询。而且，是的，这是我见过的最大和最复杂的查询。：）
