I've looked through a number of tutorials and asks, and haven't found a working solution to my problem.
Suppose my dataset has two columns: sort_order and field_value. sort_order is an integer and field_value is a numerical (10,2).
I want to format some rows as #,#0 and others as #,#0.00.
Normally I would just do
iif( fields!sort_order.value = 1 or fields!sort_order.value = 23 or .....
unfortunately, the list is fairly long.
I'd like to do the equivalent of if fields!sort_order.value in (1,2,21,63,78,...) then...)
As recommended in another post, I tried the following (if sort in list, then just output a 0, else a 1. this is just to test the functionality of the IN operator):
=iif( fields!sort_order.Value IN split("1,2,3,4,5,6,8,10,11,15,16,17,18,19,20,21,26,30,31,33,34,36,37,38,41,42,44,45,46,49,50,52,53,54,57,58,59,62,63,64,67,68,70,71,75,76,77,80,81,82,92,98,99,113,115,116,120,122,123,127,130,134,136,137,143,144,146,147,148,149,154,155,156,157,162,163,164,165,170,171,172,173,183,184,185,186,192,193,194,195,201,202,203,204,210,211,212,213,263",","),0,1)
However, it doesn't look like the SSRS expression editor wants to accept the "IN" operator. Which is strange, because all the examples I've found that solve this problem use the IN operator.
Any advice?
Try using IndexOf function:
=IIF(Array.IndexOf(split("1,2,3,4,...",","),fields!sort_order.Value)>-1,0,1)
Note all values must be inside quotations.
Consider the recommendation of #Jakub, I recommend this solution if
your are feeding your report via SP and you can't touch it.
Let me know if this helps.
In SQL you can compare a field against a set in the form
[Foo] In {"Bar1", "Bar2", ... , "BarN"}
However I'm having trouble working out how to move a filter expression into something like this. That is, for now, I end up with:
Filter(
[MyHierarchy].[Foo].Members,
[MyHierarchy].CurentMember.Name = "1"
OR [MyHierarchy].CurentMember.Name = "2"
...
OR [MyHierarchy].CurentMember.Name = "N"
)
Since I have 20-30 comparisons, and a moderate chance of the heirarchy name changing, I'd much rather maintain a set and a hierarchy name than a long expression. Is there any way to accomplish this?
Worth bearing in mind that the context is an Excel CubeSet function, so I'm a little limited in terms of defining my own members in the WITH clause.
Assuming you have a set named SelectedMembers, you could use
Intersect([MyHierarchy].[Foo].Members, [SelectedMembers])
You could of course also code this directly, i. e.
Intersect([MyHierarchy].[Foo].Members,
{
[MyHierarchy].[Foo].[1],
[MyHierarchy].[Foo].[2],
...
[MyHierarchy].[Foo].[N]
}
)
But it might be more convenient to have the set already defined in the cube calculation script - if that is possible.
I think this is a really general programming question, since boolean syntax is more or less the same in a lot of common languages.
But still my question is for php and javascript mainly.
Suppose I want to write an if statement which returns true if a variable is equal to 2,3, or 5.
And this variable has a very long name, so like this:
if((An_Object_With_A_Long_Name.Has_Also_An_Array[With_An_Index_Too]==2)
|| (An_Object_With_A_Long_Name.Has_Also_An_Array[With_An_Index_Too]==3)
||(An_Object_With_A_Long_Name.Has_Also_An_Array[With_An_Index_Too]==5))
{
return true;
}
and I really want my code look shorter, it is less depressing to read it months after :)
so can I simplify this into something like
if(An_Object_With_A_Long_Name.Has_Also_An_Array[With_An_Index_Too]==2||3||5)
Thanks for help !
Cheater way out: For that if statement, assign An_Object_With_A_Long_Name to Object i. (If you plan to have to compare this variable several times, assign Object i the pointer of An_Object_With_A_Long_Name.
I'm trying to figure out if there's a way in mathematica where I can solve for particular variables when given other variables and a set of equations. Essentially there are 6 variables, and I'm given 3 of them and have to calculate the others using these equations-
Variables-
B,Qs,f0,R,c,L
Equations-
f0=1/(2*Pi*Sqrt[L*c])
Qs=(w*L)/R
w=2*Pi*f0
B=f0/Qs
We are given the values of any 3 of those variables and have to figure out the rest using those values.
I was thinking perhaps using Eliminate but I'm not sure exactly how that would be structured as I've only used it previously with set variables that don't change and a single output.
When using the Solve function with Mathematica, you can specify for what variables you want Solve to specify the solutions. Note that Solve may not be able to find expressions in terms of these variables (if the equations you give it are contradictory or insufficient) or for all values as some functions have no inverse or only partial inverses.
Your question looks a lot like homework in Electromagnetics, but here is an example with your original problem. You will have to adapt these ideas to give to Solve the set of variables you are looking for. Also remember to use == to specify equality testing. A simple = is for immediate assignment to a variable.
Solve[{f0 == 1/(2*Pi*Sqrt[L*c]), Qs == (w*L)/R, w == 2*Pi*f0, B == f0/Qs}, {f0, B, c}]
{{f0->w/(2 [Pi]), B->w/(2 [Pi] Qs), c->L/(Qs^2 R^2)}}
Here is the single line from one of my functions to test if any objects in my array have a given property with a matching value
Return ((From tag In DataCache.Tags Where (tag.FldTag = strtagname) Select tag).Count = 1)
WHERE....
DataCache.Tags is an array of custom objects
strtagname = "brazil"
and brazil is definitely a tag name stored within one of the custom objects in the array.
However the function continually returns false.
Can someone confirm to me that the above should or should not work.
and if it wont work can someone tell me the best way to test if any of the objects in the array contain a property with a specific value.
I suppose in summary I am looking for the equivalent of a SQL EXISTS statement.
Many thanks in hope.
Your code is currently checking whether the count is exactly one.
The equivalent of EXISTS in LINQ is Any. You want something like:
Return DataCache.Tags.Any(Function(tag) tag.FldTag = strtagname)
(Miraculously it looks like that syntax may be about right... it looks like the docs examples...)
Many Thanks for the response.
Your code did not work. Then I realised that I was comparing to an array value so it would be case sensitive.
However glad I asked the question, as I found a better way than mine.
Many thanks again !
