Queries :: Calculate Moving Average - Make Table Query Type Incorrect
Aug 16, 2015
I found the attached example a while back (can't find the site again though ) and it calculates a moving average. I've hacked out the parts I need for my own work and I can create my moving average query without an issue.
However, I need to extract the MA data into a table so planned on using append. I kept getting type errors so I tried make table to see what type it was creating and it appears to be Short Text rather than a number.
I've added an extra button and Make Table query to the example.
As far as I can tell from the code, the moving average value when calculated is a Single. However, when I write it to the table, its a Short Text.
How do I make the created Table use Number Type for my calculated moving average?
Using Access 2013

Is there any formula or any way to calculate moving average on access? What I need is to calculate a value based on data from the past 3 months:
I have following structure for example:
Column A ----- Column B -------- Column C
ValueA1 ------- Value B1 ---------
ValueA2 ------- Value B2 ---------
ValueA3 ------- Value B3 --------- =average (ValueB1, valueB2, valueB3)
ValueA4 ------- Value B4 --------- = average (valueB2, valueB3, valueB4)
My main point id how to calculate values for column C.

I obtained data for earnings by industry for men and women over time (5 years). I developed crosstab query that showed the average earnings for men and women for the 5 years.
Now I want within this query to calculate the differential between men and womens average earnings and calculate a percentage within this crosstab query. I tried to use Expressionbuilder with little luck.

I am trying to construct a crosstab that averages a calculated field from a previous query. It is returning a "Data Type Mismatch" message.
The field I am trying to average is a subtraction of dates to find total days. I assume my field is not a number so I have tried to wrap it in CDbl() to change the type.
The formula is
Code:
CASE_DAYS: CDbl(IIf([Actual Close Date]-[Creation Date]>=0,[Actual Close Date]-[Creation Date],""))

I have a query that pulls data from a table called Data. I'd like to add a column to the query that will be the moving average -- For example, for a Month Beginning Date of 12/2013, it would average the SumOfCount variable for 10/2013, 11/2013, and 12/2013.
This is the sql code for my query without the moving average:
SELECT Data.Behavior, Sum(Data.Count) AS SumOfCount, Data.[Month Beginning Date], [First Name + Last Name].Wing, Data.[Full Name]
FROM Data INNER JOIN [First Name + Last Name] ON Data.[Full Name] = [First Name + Last Name].[Full Name]
GROUP BY Data.Behavior, Data.[Month Beginning Date], [First Name + Last Name].Wing, Data.[Full Name]
HAVING (((Data.Behavior)="PRNs") AND ((Data.[Full Name])=[forms]![report parameters]![fullname]));
How to insert that column into my code?

Have searched but could not find my solution. I have a bowling league database and I am doing averages based on games bowled. On certain averages the results are incorrect. Such as
Tot pins = 1169 divided by
tot games = 6
the result should be 194.83
but the result in my query is 196
have tried the Round function, Abs function and cLng function to no avail.
Thank you

I have to create a query to calculate the Base Income per room.
Guest 1-4 is the standard room rate say $125/day, guests 5 & 6 pay additional $20 charge per day. Guests staying for seven days or more receive a 10% discount. How to build this expression into a query in access. If it was Excel that would be easier.
Table info I have is:
Room
Arrival Date
Departure Date
No of Guest (per room)

i have a query that pulls a read-only SQL table, i have check in that table and the date field is set up as a Date/Time type, however the db was set up with the date and time in the same field. (1/1/2014 9:00:00 AM)
I have set up the SQL code below to pull out just the Date and not the time. however when i enter my criteria on the form, only the correct month and days load, it pulls in all other years with that month/day.
my Access level - on the lower end of medium experienced.
SELECT IIf(InStr([dbo_Rides]![ApptDatetime]," "),Left([dbo_Rides]![ApptDatetime],InStr([dbo_Rides]![ApptDatetime]," "))) AS [Date], IIf(InStr([dbo_Rides]![ApptDatetime]," "),Mid([dbo_Rides]![ApptDatetime],InStr([dbo_Rides]![ApptDatetime]," ")+1)) AS [Time]
FROM dbo_Rides
WHERE (((IIf(InStr([dbo_Rides]![ApptDatetime]," "),Left([dbo_Rides]![ApptDatetime],InStr([dbo_Rides]![ApptDatetime]," ")))) Between [Forms]![frmMain]![subTCTools].[Form]![snavHistory].[Form]![subnDriver]![txtFromDate] And [Forms]![frmMain]![subTCTools].[Form]![snavHistory].[Form]![subnDriver]![txtToDate]));

I have a query (that gets it's data from several other queries) with a column called "max." The data in the column is correct, but when I call on the query in VBA, it shows me incorrect data.Here is where I call the query:
Code:
Dim db As DAO.Database, qdf As DAO.QueryDef, rs As DAO.Recordset
Dim strReport As String
Set db = CurrentDb()
Set qdf = db.QueryDefs("7-ErrorsReport")
qdf.Parameters(0) = Forms!frmmain!dt1.Value
qdf.Parameters(1) = Forms!frmmain!dt2.Value
qdf.Parameters(2) = Forms!frmmain!d2.Value
[code]....
The query looks at a table of employees and finds out if they have been issues a warning letter before, then prints out a corresponding report based on the "max" warning level they are at.The problem arises when an employee graduates from a 6 month probation period - all letters in that period should be ignored. As i said, they are ignored correctly when i run and view my query ("7-ErrorsReport") because they are filtered out at that point, but for some reason when this code runs, it somehow sees the previously issued letters which are stored in a table and likely in some of the other queries.
I am not sure if there is some issue with the query tree I have set up which is necessary to get the results I need, or if something is wacked with the was I am using it as a recordsource.

Currently using a lot of Power Pivot Tables which in part calculate "averages" - but when the data comes form a Query that contains a calculated field using the iff() funtion such as: Outcome: iff(Status = "P", 1,0) we end up with a lot of zeros that create a problem in calcuating a true average. In the following example 2,3,0,1,0,0 the average is "1" but if the zeros were blank the average would be "2" because the blank cells would not be counted.
Is ther a way to have something like: Outcome: iff(status = "P",1,"blank") but what I want is ether 1 or a blank cell, NOT TEXT. If we use "" for the false outcome we still have cells that look blank but are in fact text cells and are counted in calculating average.

I have a parameter query that contains information on a list of people and contains 3 checkboxes: alumni, parent, business
In this query, I am trying to use parameters to filter the results based on these three fields i.e.
true, false, true would return all records where either alumni, business or both are true, and parent can be either true or false.
false, true, false would return all records where only parent is true, and the other fields do not matter.

I am developing a Make Table Query from 2 tables, one of which has an "Employee Name" field (lastname,firstname) and the other table has separate fields for LastName and FirstName. I've been able to accomplish almost what I need by:
WHERE ((([Table 1].[EMPLOYEE NAME]) Like [Table 2].[LAST NAME] & "*"));
Which works fine except when there are 2 employees having the same last name, then it generates duplicates. I suspect there must be a way to do this by incorporating the first name field in the sql statement but that's beyond my ability. I realize that names are not good things to base a query on, but the 2 existing tables have been preset and populated by others and I don't really have the capability to change them.

I have a report that comes from a query with multiple expressions. The expressions look something like this:
IIF([TimeArrive]>[TimeTriage],DateDiff("n",[TimeArrive],[TimeTriage])+1440,DateDiff([TimeArrive],[TimeTriage]))
This works great and my report gives me my columns for each expression in minutes they way it should. Now here is the question...is there a way to insert a text box for each column/expression so I can calculate the Average for each column/expression?
i.e. I want the report to show the average minutes of Expr1 and Expr2, etc at the bottom of each column.

I am trying to run a make table query that involves using a linked table in Ms from a SharePoint list. However, a few columns I wish to include in my Make table query are calculated columns from the SharePoint list.
The make table query will not run saying "Calculated columns are not allowed in SELECT INTO statements".
Can any think of a solution or a potential work around to this?
I need to create a table with these columns in it.

I have a running total query that seems to run but when I try to total the query results then Access will be "Not Responding". I tried to change it to a Make Table query because I need to use the running total result in another query. So I created a table but when I try to run the make table query it just says "Run Query" at the bottom. Here is the query:
SELECT [OTMissing].[Employee], [OTMissing].[AsOf], [OTMissing].[HRsEarn], (SELECT Sum(OT1.[HRsEarn]) FROM [OTMissing] As OT1
WHERE OT1.[Employee]=[OTMissing].[Employee] AND OT1.[AsOf] <=[OTMissing].[AsOf]) AS RunningTotal, [OTMissing].[RemainPP] INTO OTGenerated
FROM [OTMissing]
ORDER BY [OTMissing].[Employee], [OTMissing].AsOf;
My OTMissing query is 47061 rows. Does that have something to do with it? The only other thing it might be is that most of the records have 0 although I'm not sure why it would be a problem I thought I would at least mention it.
