                                            | In an ssrs 2008 r2 report, I found the following expression that I am trying to understand what it means:=iif(Fields!Gr.Value = "01", "01 Total Score", iif(Fields!Gr.Value = "02", "02 Total Score", iif(Fields!GradeLevel.Value = "03", "04 Total Score", "All Levels"))))I think it means the following  If Fields!Gr.Value = "01", then value = "01 Total Score",  else  If Fields!Gr.Value = "02", then value = "02 Total Score", else  If Fields!Gr.Value = "03", then value = "03 Total Score",else (for anything else, the value is "All Levels".Can you tell me if my assumption is true or not? If not, would you tell me what this statement really means?Also would you point me to a url that explains this kind of logic structure for ssrs 2008 r2? |  |

                                          | yes. your assmuption is correct. It uses a set of nested IIF to check the various conditions.The above nested iifs can be simplified using Switch statement like=Switch(Fields!Gr.Value = "01", "01 Total Score" ,        Fields!Gr.Value = "02", "02 Total Score",        Fields!Gr.Value = "03", "03 Total Score",        1=1, "All Levels")------------------------------------------------------------------------------------------------------SQL Server MVPhttp://visakhm.blogspot.com/https://www.facebook.com/VmBlogs |
