I need to create a numeric field that would calculate the number of records in a cross-reference field. My version of RSA Archer GRC is 6.5.
As I understd, there isn't any standard function for this type of calculations. At least I can't find it. I can use Data Feed for this task, but calculated field is much better solution.
Alexander you can use COUNTA([Cross-reference Field]) and that will return the number of cross-reference numbers linked to the record
If you want to simply count the number of records in a cross-reference, related record or a sub-form, use the COUNTA function, either in a calculated text or a numeric field:
COUNTA([Cross Reference Field])

For some time now I have the impression that a field and a column are the same thing in SQL server but today I stumbled across the statement that they are not actually the same thing. It was stated that a field is the intersection of a row and a column, so if a table has 10 rows and 10 columns it will have 100 fields in total.
I looked at Microsoft Docs and this is what it says:
A column is collection of cells aligned vertically in a table. A field is an element in which one piece of information is stored, such as the eceived field. Usually, a column in a table contains the values of a single field.
In this case then it looks like they are not the same thing.
I would highly appreciate it if someone can clarify this! Thank you in advance!
A field is part of a row, not a table, a "column of a row", if you will.
However, a lot of people use these terms interchangeably, and you can (read: have to) often deduce what they actually meant by the context of the sentence.
In some contexts, a field may refer to an element within a data value, where a column contains the entire data value. A common example is a date data type, where the month, day, and year are fields within the column. Spatial data types (e.g., the PostGIS data type in Postgres) is another example, where the x coordinate, y coordinate, and spatial reference ID are all fields within the column. Some kinds of identifiers have application-specific fields within them, where, for example, the first two characters carry some information, the next four characters convey some other information, etc. In cases like these, the distinction between column and field is important.
I am attempting to use VLookup to match a "Purchase Number" to a specific "Invoice Number". To accomplish this, I have several identifiers about the purchase that I put together to come up with a special "Concat ID". I then have a list of Invoice Numbers that also has the same list of identifiers to create the same "Concat ID'.
The problem I am running into is that the set of identifiers is not unique (aka a purchase of 10 Computers might happen multiple times a year, therefore it is in my list multiple times). Because of this, when I use Vlookup to match the 2 IDs, it always is giving me the same Purchase Number for each time the Concat ID is found (which is just the first occurrence of that Concat ID).
Since there is no other data that would allow for matching (because Invoice date and purchase date are not always the same date or even close to one another), I am just wanting to ensure that each Invoice Number has a unique purchase number.
I'm not sure if its possible, but I was hoping I would be able to perform the vlookup then just skip to the next time the Concat ID is found, allowing for no duplicates, but that hasn't been feasible for me. Because this is a file of 16000 rows, any insight is very appreciated.
I'm sure that's not the clearest explanation, so I've attached a screenshot of the 2 examples in case anyone has any insight. I've been using a simple VLookup, but I'm open to trying VBA or any other suggestions everyone has. As always, thank you Stack community in advance for any help/insight!
Purchase Info
Attempted Matchup with Invoice Info
I'm still not sure what you expect to do with the ConcatID purchase number, but to return the purchase numbers that match your specific ConcatID, generated in the manner you describe in your question, and "skipping to the next" in the case of identical ConcatID's, you can do something like the following;
Note that I made a Table out of your original data, and am using structured references. This allows a much smaller amount of data to be processed compared with referencing the entire column, and will also autoadjust the range as you add/remove rows
Also note that if your Table starts in other than Row 1, you will need to make an adjustment in the formula to account for that.
G2: =INDEX(PurchaseTbl[#All],AGGREGATE(15,6,1/1/(PurchaseTbl[Concat ID]=F2)*ROW(PurchaseTbl),COUNTIF($F$1:F2,F2)),7)
and fill down as far as needed
I've got a really dorky solution, but maybe it will help.
Use this formula to create a unique ID for each row. It will count how many times the specific Concat ID has been used previously in the table, then append it to the end. You can use the Concat ID Unique in your VLookup to get the correct Purchase Number.
=D2 & "_" & (COUNTIF(D$1:D1, "=" & D2))
Unlike Tablix, I was not able to use limiting expression such as =ceiling(rownumber(nothing)/6) in Matrix.
Do you have any ideas to achieve limiting no. of columns in matrix- in design only, without touching dataset.
Or I should create it in Tablix?
Any suggestions please?
I think the only way you could achieve this would be to specify the column and row that you want your data to appear in from within your source dataset.
This could be achieved by taking a row_number and then doing integer division (<row_number value>/6) to get the row it should fall into and then modular division (<row_number value>%6) to get the column it should fall into.
From here you can build up your tablix grouping on your row and column fields.
I am New in MS Access My Question is How to make AutoNumber Column to make an Random Numbers but with some Condition like Make Number from 10 digits only and Positive
As far as I know:
There is an option to Randomly generate an AutoNumber column. There isn't an option to make them only positive and 10 digits.
I actually use this in one of my tables, and typically the length is 8+ digits, however there are negative numbers. Neither fits your criteria.
If you go to the design view of your Table, select the column in question. Make sure the Data Type is AutoNumber, and locate the Field Properties pane at the bottom. You can select Random in the New Values dropdown list.
Unfortunately, I think you would have to take this into your own hands and create a public function to do this for you.
I want to create data that contains info about my supplier making it auto generate his ID.
For example, SupplierID I want it to appear as - SID001, SID002 all to auto generate after each other.
How do I do this with SQL?
Ask yourself this: what are the costs of doing this? In particular, what is required to compare two strings versus comparing two numbers? To generate strings from numbers?
Then ask yourself, what value is added by having an id of 'SID0001' rather than just 001?
Then ask yourself, is there an easy way to display a prefix without redundantly storing it for each row? (Answer: yes, with a database view).
You could just use a sequence or identity column and store the prefix in a separate column, or alternately, if the table in question will only ever have suppliers with a prefix of SID, don't store the SID part at all and simply add it at the application level.
You could check for the next ID available and concatenate your prefix with that value. The result should be inserted in the SupplierID column.
Some databases(Oracle, postgres etc) support a sequence for number part. Some(mysql) have an auto increment feature, so you get new number when inserting.
You could then concatenate with string to generate string based IDs.
