Access 2013 Calculation with If Statement - ms-access

Maybe someone can help me. What I am trying to do is to create a calculation with an If Condition. I'm doing my current calculations in the field within my DesignerView.
=Summe([Menge/Liter])
=Summe([Menge/Liter]*[Preis/Liter])
Here i need to have that it only calculates the tables that have status = 1
Is there a way how to do this?

Use IIf Function:
=IIF(status = 1, Summe([Menge/Liter]*[Preis/Liter]), Summe([Menge/Liter] ))
Or is it:
=IIF(status = 1, Summe([Menge/Liter]*[Preis/Liter]), "")

SSRS - IIF error in Report Builder

I am having an issue with a divide by zero error that I have half way worked through.
Basically I need (EstimatedValuePlanned - EAC) / EstimatedValuePlanned
I have the following, however I am still getting #Error on some:
= IIF (Fields!EstimatedValuePlanned.Value = 0 , 0,
Fields!EstimatedValuePlanned.Value - Fields!EAC.Value)
/
SUM(Fields!EstimatedValuePlanned.Value)
I have changed the code around several times but I still either get Error or NaN
Thank you
IIF will always evaluate both parts of the function, so when SUM(Fields!EstimatedValuePlanned.Value) is zero you will get the error even though that's not what will be returned.
Try using a SWITCH statement. SWITCH stops once an expression returns True.
Something like this
= SWITCH(
SUM(Fields!EstimatedValuePlanned.Value) = 0 , 0,
True, (Fields!EstimatedValuePlanned.Value - Fields!EAC.Value) / SUM(Fields!EstimatedValuePlanned.Value)
)
The True expression simply acts like an else
UPDATE WITH SAMPLE
I created a new report added a dataset and set the dataset query to be the following (just to generate some dummy data).
DECLARE #t TABLE (EVP float, EAC float)
INSERT INTO #t VALUES
(1,2),
(2,3),
(5,4),
(0,2),
(1,0),
(0,0)
SELECT * FROM #t
I then added a table, set the first to columns to be EVP and EAC respectively and set the 3rd column to an expression as follows.
=SWITCH (
Fields!EVP.Value = 0, 0
, True, (Fields!EVP.Value - Fields!EAC.Value) / Fields!EVP.Value
)
The report design looks like this.
And when it's run this is the result....
Try replicating the above steps and see if you can get it to work like this first then review difference to your report.
I got it to work with:
=IIF (Fields!EstimatedValuePlanned.Value = 0 , 0,
Fields!EstimatedValuePlanned.Value - Fields!EAC.Value)
/
IIF(Fields!EstimatedValuePlanned.Value =
0,1,Fields!EstimatedValuePlanned.Value)
Thank you both

Multiple Or in an IIF function

Given this data: Complete Dataset
I only want to get the Total_AR of those TransactionYrMonth=ParameterPeriod so I produced it using this code:
=IIF(
IsNothing(Sum(Fields!Total_AR.Value)),0,
Sum(IIF(Cdate(Fields!TransactionYrMnth.Value)=Cdate(Parameters!Period.Value),
Fields!Total_AR.Value,0)
)
)
From there, I got this dataset:
Filtered Dataset
Now, what I need to do is to get the sum of the first 3 service months starting from January to March that is equal to the latest transaction month which is April.
So the sum should be equal to $204,329 + -$96,640 + -$259,008 = -$151,319
To make it possible, I tried to use a code like this:
=Sum(IIF(
Cdate(Fields!TransactionYrMnth.Value)=Cdate(Parameters!Period.Value) And (
Cdate(Fields!ServiceYrMnth.Value)=DateAdd(DateInterval.Month, -3, CDate(Parameters!Period.Value)) Or
Cdate(Fields!ServiceYrMnth.Value)=DateAdd(DateInterval.Month, -2, CDate(Parameters!Period.Value)) Or
Cdate(Fields!ServiceYrMnth.Value)=DateAdd(DateInterval.Month, -1, CDate(Parameters!Period.Value))), Fields!Total_AR.Value,0
))
I have no luck producing it. I even got an error saying
‘Textbox11.Paragraphs[0].TextRuns[0]’ contains an error: [BC30516] Overload resolution failed because no accessible 'IIf' accepts this number of arguments.
Anyone, please help?
I got a solution already using this code:
=Sum(IIF(
Cdate(Fields!TransactionYrMnth.Value)=Cdate(Parameters!Period.Value) And
CDate(Fields!ServiceYrMnth.Value) >= DateAdd(DateInterval.Month, -3, CDate(Parameters!Period.Value)) And
CDate(Fields!ServiceYrMnth.Value) <= DateAdd(DateInterval.Month, -1, CDate(Parameters!Period.Value)), Fields!Total_AR.Value, 0
)
)

Sum values in ssrs with excluding one field

I have a report and need to Sum values from Input_Type (they are Actuals, Adjustment, Estimate, Forecast and Budget, but I need to exclude Budget).
If I use this condition, I get an error.
=SUM(IIF(Fields!INPUT_TYPE.Value = "Actuals" + Fields!INPUT_TYPE.Value = "Adjustment" + Fields!INPUT_TYPE.Value = "Estimate" + Fields!INPUT_TYPE.Value = "Forecast",Fields!VALUE.Value, 0), "GlobalReport")
Could you please help me?
Try the reverse of what you're attempting to write.
=SUM(IIF(Fields!INPUT_TYPE.Value = "Budget", 0, Fields!VALUE.Value), "GlobalReport")

Webmatrix if statement issues. any ideas?

I have written a SQL query, which extracts the lowest weekly price for a property stored in my database:
var rPropertyId = Request.QueryString["PropertyID"];
var cheapestrate = "SELECT TOP 1 * FROM RateInfo WHERE PropertyID=#0 ORDER BY RateWeekly ASC";
var qcheapestrate = db.QuerySingle (cheapestrate, rPropertyId);
I'm pretty confident that this statement is correct. The problem i have, is that not ALL propertys have pricing, so i only want to show this price if they do. I have created the below if statement, but it's telling me i'm missing an ; somewhere?
#if(qcheapestrate=!null){
Rates From qcheapestrate.rateweekly per week
}
So i'm trying to check if the query returns an entry. if it does, i want to show the lowest "rateweekly" value. Hopefully this all makes sense!
Try this...
#if(qcheapestrate!=null){
<text>Rates From</text>
#qcheapestrate.rateweekly
<text>per week</text>
}

Sqlalchemy: Produce OR-clause with multiple filter()-Calls

I'm new to sqlalchemy and could use some help.
I'm trying to write a small application for which i have to dynamically change a select-statement. So I do s = select([files]), and then i add filters by s = s.where(files.c.createtime.between(val1, val2)).
This works great, but only with an AND-conjunction.
So, when I want to have all entries with createtime (between 1.1.2009 and 1.2.2009) OR createtime == 5.2.2009, I got the problem that i don't know how to achieve this with different filter-calls. Because of the programs logic it's not possible to use s= s.where(_or(files.c.createtime.between(val1, val2), files.c.createtime == DateTime('2009-02-01')))
Thanks in advance,
Christof
You can build or clauses dynamically from lists:
clauses = []
if cond1:
clauses.append(files.c.createtime.between(val1, val2))
if cond2:
clauses.append(files.c.createtime == DateTime('2009-02-01'))
if clauses:
s = s.where(or_(*clauses))
If you're willing to "cheat" by making use of the undocumented _whereclause attribute on Select objects, you can incrementally specify a series of OR terms by building a new query each time based on the previous query's where clause:
s = select([files]).where(literal(False)) # Start with an empty query.
s = select(s.froms).where(or_(s._whereclause,
files.c.createtime.between(val1, val2)))
s = select(s.froms).where(or_(s._whereclause,
files.c.createtime == datetime(2009, 2, 1)))
Building up a union is another option. This is a bit clunkier, but doesn't rely on undocumented attributes:
s = select([files]).where(literal(False)) # Start with an empty query.
s = s.select().union(
select([files]).where(files.c.createtime.between(val1, val2)))
s = s.select().union(
select([files]).where(files.c.createtime == datetime(2009, 2, 1)))
