I have an access database with over 210k records. they are a list of product codes. with associated product codes. I want to create an access query that associates only one product code per line but merges the associated products into a single column matched to that product code but sepertaed by a , (comma)
Example of columns in access database
Product code: Associated product
100000 2548741
100000 4578214
100000 1254712
100000 5687412
100000 1469787
100000 9874582
100000 5478126
I want the following
Product code: Associated product
100000 2548741,4578214,1254712,5687412,1469787 ,9874582, 5478126
Thanks in advance.
This is how to do in vba: http://support.microsoft.com/kb/318642
Create a SQL query that retrieves the data that you want.
Use some client-side code to format the data the way you want.
SQL is used to manipulate (retrieve, add, remove, update) data, not to format it in a specific output format.

In my Anylogic model I succesfully create plots of datasets that count the number of trucks arriving from terminals each hour in my simulation. Now, I want to add the actual/"observed" number of trucks arriving at a terminal, to compare my simulation to these numbers. I added these numbers in a database table (see picture below). Is there a simple way of adding this data to the plot?
I tried it by creating a variable that reads the database table for every hour and adding that to a dataset (like can be seen in the pictures below), but this did not work unfortunately (the plot was empty).
Maybe simply delete the variable and fill the dataset at the start of the model by looping through the dbase table data. Use the dbase query wizard to create a for-loop. Something like this should work:
int numEntries = (int) selectFrom(observed_arrivals).count();
DataSet myDataSet = new DataSet(numEntries);
List<Tuple> rows = selectFrom(observed_arrivals).list();
for (Tuple
row : rows) {
myDataSet.add(row.get( observed_arrivals.hour ), row.get( observed_arrivals.terminal_a ));
}
myChart.addDataSet(myDataSet);
You don't explain why it "didn't work" (what errors/problems did you get?), nor where you defined these elements.
(1) Since you want both observed (empirical) and simulated arrivals per terminal, datasets for each should be in the Terminal agent. And then the replicated plot (in Main) can have two data entries referring to data sets terminals(index).observedArrivals and terminals(index).simulatedArrivals or whatever you name them.
(2) Using getHourOfDay to add to the observed dataset is wrong because that just returns 0-23 (i.e., the hour in the current day for the current model date). Your database table looks like it has hours since model start, so you just want time(HOUR) to get the model time in elapsed hours (irrespective of what the model time unit is). Or possibly time(HOUR) - 1 if you only want to update the empirical arrivals for the hour at the end of that hour (i.e., at the same time that you updated the simulated arrivals).
(3) Using a Variable to get the database value each hour doesn't work because a variable's initial value is only evaluated once at model initialisation. You want an hourly cyclic Event in Terminal instead which adds the relevant row's value. (You need to use the Insert Database Query wizard to generate the relevant Java code for the query you need in the event's action.)
(4) Because you have a database table with specifically-named columns for each terminal (columns terminal_a and presumably terminal_b etc.) that makes it slightly more awkward. (This isn't proper relational table design where, instead of 4 columns for the 4 terminals, you'd instead have two columns for terminal_id and observed_value with a row for each time period and terminal combination.)
So your database query expression (in your Terminal agents) will need to use the SQL format (not the QueryDSL format) so that you can 'stitch in' the correct column name into the SQL.
I have a dataset including 3 columns :
ID transac (The unique ID of the transaction - Dimension)
Source (The source of the transaction - Dimension)
Amount € (The amount of the transaction - Stat)
screenshot of my dataset
To Count the number of transactions (for one or more sources), i use COUNT_DISTINCT function
I want to make the sum of the transactions amounts (for one or more sources). But i don't want to additionate the amounts of the transactions with the same ID !
Is there a way to do this calcul with a DataStudio function ?
Thanks for your answers. :-)
EDIT : I saw that we could do this type of calculation via SQL here and I would like to do this in DataStudio (so that I don't have to pre-calculate the amounts per source.)
IMO, your dataset contains wrong data. Each value should be relative only to that line, but this is not the case: if the total is =20, each line should describe the participation of that line to the total. With 4 sources, each line should be =5 or something else that sums 20.
To solve it in DataStudio, you need something like CALCULATE function in PowerBI, but currently DataStudio doesn't support this feature.
But there are some options to consider to repair your data:
If you're sure there are always 4 sources, just create a new calculated field with the expression Amount/4 and SUM it. It is not an elegant solution, but it works.
If your data source is Google Sheets, you can easily repair the data using formulas, like in this example:
Link to spreadsheet
For this spreadsheet, I used this formula in adjusted_amount column: =C2/COUNTIF(A:A,A2). With this column in DataStudio, just use the usual SUM aggregation function to summarize it correctly.
i need to store data about activity houses for youngsters which should be stores like 15-19, 12-20, 10-23, 10-19 etc.
and then i want to be able to search that which one or more of them matched the incoming query.
for example some one want to search for activity houses that are suitbale for 20 so it should return houses that have 12-20 and 10-23.
thanks in advance.
Create your table with 2 columns representing the range allowed, e.g., minCapacity and maxCapacity.
Then you can structure your query using BETWEEN. e.g.
... WHERE #request BETWEEN minCapacity AND maxCapacity.
I have a view which returns 4 columns, Date (filtered by day using datediff), Quantity, Document number.
The field Document Number returns an integer (1-8) but I need it to return for example (1 = Warehouse, 2 = Office, etc etc) Unfortunately, these values don't exist anywhere in the database.
Any help would be appreciated, on how to achieve this and whether this can stay within a view or has to be done via SQL query instead
One option is to use CHOOSE()
Example
Select choose(SomeIntValue,'Warehouse','Office', ...)

I'm fairly new to SQL and I have been issued my first report to build. I have written an SQL query to give me a set of results that I would like to publish in a report.
I have unioned about 20 small queries all containing the correct amount of columns. One column is a misc column with about 15 different descriptions in (this is what I want to count).
I have uploaded my data set and now want to be able to choose a cell in my report to bring back a certain description.
At the minute I'm using
=count(fields!misc.values)
and it's giving me the whole count, about 200.
I would like to know if there is any kind of "where clause" (filter) which I can use to state which description results I want to bring back.
You can use am expression to count the misc.value you need. It will work like a count using a where clause:
=Sum(iif(Fields!misc.Value ="Some description",1,0))
Example:
For count the FSMethod with MethodOne as value I used this expression:
=Sum(iif(Fields!FSMethod.Value ="MethodOne",1,0))
Note the expression sums by 1 if the FSMethod.Value is MethodOne.
For count the rows with FSMethod column with MethodTwo value.
=Sum(iif(Fields!FSMethod.Value ="MethodTwo",1,0))
Let me know if this can help you.
