在 ssrs 中组合 IIF 语句

Question

我试图在 SSRS 中组合以下 IIF 语句，但似乎无法使代码正确到运行。有人可以帮忙吗？

=Iif(IsNothing(Fields!Description.Value) 和字段！CallFlag.Value = "1" , "New Record to Dial", 字段!Description.Value, Iif(IsNothing(Fields!Description.Value) 和 fields!CallFlag.Value = "0" , "Do Not Call", Fields!Description.Value, Iif(IsNothing(Fields!Description.Value) and isnothing(fields!CallFlag.Value), "Load Reject", Fields!Description.Value)

Answer 1

IIF 语句读取 IIF(boolean, TRUE-value, FALSE-value)。在您的情况下，您的意思是：if callflag=1 then "New Record" else if callflag=2 then.......

这将导致：

=Iif(IsNothing(Fields!Description.Value) and fields!CallFlag.Value = "1" ,
  "New Record to Dial", 
  Iif(IsNothing(Fields!Description.Value) and fields!CallFlag.Value = "0" ,
    "Do Not Call", 
    Iif(IsNothing(Fields!Description.Value) and isnothing(fields!CallFlag.Value),  
      "Load Reject", 
      Fields!Description.Value
    )
  )
)

如果您重新配置，您会得到：

=Iif(IsNothing(Fields!Description.Value) and fields!CallFlag.Value = "1" ,
  "New Record to Dial", 
  Iif(IsNothing(Fields!Description.Value) 
    iif(isnothing(fields!CallFlag.Value), "Load Reject",
      Iif(fields!CallFlag.Value = "0" ,   "Do Not Call", 
        Iif(fields!CallFlag.Value = "1" ,   "New Record to Dial", "Error on CallFlag Value")
      )
    )
 , Fields!Description.Value)

甚至更好：如果您使用 SQL-server 作为标签指示，请使用 CASE 命令... CASE command in SQL
