I'm super confused how to apply the if/else statement in an Access table field, not a query. Please help! Here is what I'm required to do based on the table I constructed:
Fill in the overall rating field, using this formula: If the is available field is false, the overall rating is “pending”, regardless of the scores. Otherwise, if each rating score is 9 or above, the rating is ''excellent"; if the interview average is 9 or above and one rating score is less than 9, the rating is ''very good"; if the interview average is less than 9 and one (or both) rating score is 8 or above, the rating is "erratic"; otherwise the rating is "reject".

From Access 2010 onward you can indeed create calculated fields in a table. To do that, open the table in Design View, enter the name for the new column and choose Calculated as its data type.
Use the Expression Builder or any external text editor to build/write the expression for the calculated field. There is only a limited subset of functions available to be used in a calculated table field. So in this case the Expression Builder actually is helpful, as it shows only functions that can be used in this context.
To achieve the result as per your requirements, you will need an expression with several nested Iif-Function calls. (The Switch function is not available here.)
The actual expression will be same as you would use in a query.
This is how you can do it, if you really want to. – I agree with the commenters that in almost any case it would be better to use a query to do any calculation of this kind.

I realize that this question is quite basic. And I have found various answers on various other forums - all of which use SQL which for the purpose of this assignment (it is for school) I cannot use. I have to physically type the answer into the Field box.
The question reads as such: "Add a calculated field in the third column. Name the field ExtendedAmount. This field should multiply the quantity ordered (from the Order Details table) by the unit price for that item (from the Products table). This will calculate the total amount for each order. Format the calculated field as Currency and change the caption to Total Dollars. Change the Total row to Sum."
I have attached a screenshot of what I tried, in Design View, as well as the relationships of the tables required for the question and other parts of the query. When I click "Run" that is where I hit a snag - it provides and other box which says, "Enter Parameter Value" which as I understand it should be supplied by the Order Details Table.
Does anyone have any idea as to what I can do to fix this? Here is the expression I built as well --- ExtendedAmount: ([QuantityOrdered]*[UnitPrice])
Thanks,
Josh
The quantity field is called [Quantity], not [QuantityOrdered]. Adjust your expression accordingly.
We're trying to create a template date prompt to be used across multiple universes, and also be used against multiple date fields (for instance, Transaction Date, Invoice Date, etc)
The prompt should display a list of values like the below (there's about 30 total):
Date Range START_DATE END_DATE
-------------------- ------------------------------ --------------
D: Yesterday 12/02/2015 12/03/2015
M: Month Before Last 10/01/2015 10/31/2015
M: Month to Date 12/01/2015 12/02/2015
Our initial attempt at this (creating a derived table, and then some aliases against the derived table, with one alias for each date type such as Transaction Date, Invoice Date, etc) was a failure - the sql generated is wrong, and includes the sql that's just supposed to provide the list of values. I think we need to use a different approach entirely.
Thanks for reading so far. I would greatly appreciate any ideas! Feel free to ask questions and I'll edit my notes to answer.
EDIT - we're using UNV (legacy Universe Design tool)
I'm going to assume you have an existing (dimension) table that contains a record for each date and the necessary columns to hold the different representations. You can also create a derived table for this.
Here are the steps to achieve what you described (sorry, no screenshots, this is off the top of my head):
Create the required dimension objects (based on your date table) in a separate class in the universe (you can hide this class at the end; the end user shouldn't see them).
Take one of the date dimension objects (e.g. Transaction Date, Invoice Date. …), enable the LOV option and edit it (which should bring up the query panel).
In the query panel, select all the dimension objects, created in step 1, that you want to show in your LOV. Important: the object holding the value to be returned, should be placed first in the query panel. Run the query (nothing will appear though).
Make sure that you enable the option to Export the LOV, otherwise your customisations will be lost upon exporting the universe. Optionally, enable the option to refresh the LOV each time the user calls it.
As you can't really define a single, reusable LOV in UDT that you can reference in different dimension objects, you'll have to perform this for each dimension object that you would want to have this LOV.
One way around this annoyance may to define the customised LOV once, note down the generated LOV name (about 8 alphanumeric characters long) and then replace the LOV name in the other dimensions with that LOV name. I'm can't guarantee that this will work though.
In contrast: with IDT you can define a customised LOV like this once (either in the Data Foundation Layer or the Business Layer), and then reference it as much as you want.
I have two tables and from that I am generating a query. I have columns in my query with field type yes/no. These are basically columns to determine the race of a person. The user enters information in yes/no for various races. I want another calculated column in the query which checks for all other race columns and calculates values in it.
I have to check for a few conditions in for the values in columns
For example:
1) If Hispanic is chosen, the new column should say hispanic(no matter what other options are selected. This is like a trump card)
2) If more than one is selected, then new column entry should say "multi"
3) If none of the options are selected, it should say "unknown"
4) If exactly one of them is selected, then that race should be displayed
Can anyone help me with this? I am new to Access
I can't code it for you but I can point you in the right direction. What you want to do is take all the tests you explained above and put them in a coded format :
iif ( condition, value_if_true, value_if_false )
Since you have a lot of possible outputs i'd use something like a Case Statement where you can test for all the possibilities.
Follow this link if you need any info on how to code both type of statements (iif and case).
Once you have tried something like this, you can comeback with a specific question if you encountered a problem in the process.
Good luck with your database.
I have a large table with the following fields:
Date
Product_ID
AmountEUR_Field1
AmountEUR_Field2
AmountEUR_Field3
AmountEUR_Field4
AmountEUR_Field5
where each AmountEUR field represents the sales amount for a product.
The reason for having 5 different AmountEUR fields is that they are based on different Currency Rates (in example BeginingOfMonthRate, AverageMonthRate, EndOfMonthRate etc.).
I now want to copy a specific AmountEUR field to another table, but the AmountEUR field to be copied varies over time (sometimes it is AmountEUR_Field2, other times it is AmountEUR_Field5).
Therefore I need to select a specific column based on a variable from another table. (that variable should then have value between 1 and 5).
I have been thinking about making a new field called AmountEUR_ToBeUsed that is updated with the correct AmountEUR_Field, but that brings me back to the same problem of selecting the specific column I want copied.
Can a solution be made within the Access query designer, or do I need some VBA code?
You can just make this with the Access Query designer.
Specifically you will need the function IIF.
For instance, if you want to specify that before a date you wish to use AmountEUR_Field1, and otherwise AmountEUR_Field5 you can say:
IIF(somedate<#1/1/2011#,AmountEUR_Field1,AmountEUR_Field5)
Note, depending on the settings of your PC, you may have to say:
IIF(somedate<#1/1/2011#;AmountEUR_Field1;AmountEUR_Field5)
In a report model I have some entities which have attributes which are integers (set to integer datatype) but should not be summed or aggregated in any way.
For examples ID's.
But when I create reports with the wizard, sometimes the report builder will try to sum the values even though it doesn't make sense to sum ID's.
For example let's say I have a list of cars sold in a month. In january I've sold 2 cars, one with the ID 101 and one with the ID 210. In report builder I will then - when using the wizard - get the number 311 for the summed values. I can remove it afterwards, but I would like this to not happen at all (since the end-users will be confused)
I need a way to say to the report model: This is an integer, but it is not really a number you should sum up
Well the wizard isn't perfect as you've found out. It does it's best in trying to figure out what to do. All that you can really do is remove =Sum(carID.value, "datasetname") when it automatically puts it there. Or if you don't need to sum anything at all delete the footer of the table. A workaround perhaps would be to do a Convert in your SQL to make your ID's a varchar.
If you drag an integer field onto the table it generates a sum by default. This is not always what you want - e.g. when the field is an Id or a status code that is the same for all rows shown.
Right-click the "<<Expr>>" and bring up the "Expression..." dialog. Replace "Sum" with "First" - e.g. =Sum(carID.value, "datasetname") becomes =First(carID.value, "datasetname") If the values are the same in all rows, then the first value will do. If not, there are also other functions like Last, Min, Max.
This is a bit of a kludge, but it works for me. I used my text editor to edit the RDL (XML) file and replace "Sum(" with "", then searched (carefully) for the ")" and replaced with "". I only replaced this inside of the ... Reopen in report builder without issues.
