Question

我正在尝试选择参数为drop down和From以及to date的记录。

我不知道下面的查询有什么问题，我没有得到任何记录。我知道，有条件的记录。

    Submission.Submission Status} = "Submitted" 
    and {Submission.Status} = "Active" 
    and
    ( 
      if {?Type} = "Application Date" then
      {
           {Application.Edit Date} IN {?Date From} TO {?Date To} 
      }
      else
      if {?Type} = "Submission Date" then
      (
           {Submission.Edit Date} IN {?Date From} TO {?Date To}
      ) 
      else 
      if {?Type} = "Selection Date" then
      (
        {Committee_Member.Position Start Date} IN {?Date From} TO {?Date To}
      )
 )
)

我尝试下面的查询哪个工作完美，当我尝试使用日期不起作用。任何线索？

Submission.Submission Status} = "Submitted" 
    and     
    ( 
      if {?Type} = "Application Date" then
      {
           {Submission.Status} = "Active" 

      }
      ....
      ....
      ....
   )

假设列数据类型正确并且没有拼写错误，那么您的公式没有任何问题。我唯一能建议的是简化语句，然后逐行调试，直到找到问题为止。从最简单的公式开始，运行报告，看看它是否有效。如果是，请添加下一行并重新测试。

例如，运行类型为“应用程序日期”的报告，并查看是否提供任何记录。如果没有，前两行有问题。如果您看到记录，则通过取消注释日期选择的行来再次尝试。

{Submission.Submission Status} = "Submitted" 
and {Submission.Status} = "Active" 
and
    ( 
      select {?Type}
      case "Application Date" : true
      //case "Application Date" : {Application.Edit Date} IN {?Date From} TO {?Date To}
      //case "Submission Date" : {Submission.Edit Date} IN {?Date From} TO {?Date To}
      //case "Selection Date" : {Committee_Member.Position Start Date} IN {?Date From} TO {?Date To}
      default : false
    )

那有用吗？如果是这样，请尝试下一步：

{Submission.Submission Status} = "Submitted" 
and {Submission.Status} = "Active" 
and
    ( 
      select {?Type}
      case "Application Date" : {Application.Edit Date} IN {?Date From} TO {?Date To}
      //case "Submission Date" : {Submission.Edit Date} IN {?Date From} TO {?Date To}
      //case "Selection Date" : {Committee_Member.Position Start Date} IN {?Date From} TO {?Date To}
      default : false
    )

等等，直到找到罪魁祸首。
