I am trying to sum values that are under a related table i.e.:
Sum([ServiceLines.Services.total_price])
But have had no success. I am currently getting the first value of the related table instead of a sum of all the values.
Am I doing this wrong or is this behavior not supported?

I have a quite big table as input where two fields (Id, StartTsUtc) form a unique key. the TimeStamp shows several updates for this unique key
Wanting to keep only the latest update for each (Id,StartTsUtc), I'm applying the argmax function
| summarize argmax(TimeStamp, *) by Id, StartTsUtc
The result is correct, but the columns seem to have 'max_TimeStamp_' added in their column name
Why would that happen ? And how can this be avoided ?
Is there a way to easily remove 'max_TimeStamp_' from each columname ? The columns are dynamic, so it's not possible to use a project-rename using a fixed list
You should use "arg_max()" instead of "argmax()". "argmax()" is the old version that had this undesirable behavior.
Right now im using Smartsheet API 2.0 were i can update only using a RowID (basically a fixed row number) in a Smartsheet. Instead i need to update using a value from a column which i created.
To update a cell you'll need both the row id and the column id. If you want to set a cell values for all cells created after adding a column you'll need to loop over all existing rows and update each of them.
Concerning performance and best practise, while using update rows you can send a batch of rows.
I encountered very strange issue in teradata today.I created one table from another table using following syntax:
create table a.xyz as a.abc with data;
so obviously xyz will be created exactly same as abc(including column attributes). Also data will be same. However if I execute query to get size of that table using allspace or tablesize, new table is taking more size than original table? May I know why it should be the case? I checked skew factor as well for curiosity, surprisingly skew factor of new table was less(ideally it should be same because same PI and same data). abc having UPI and one column got column level compression as well, but of course both these attributes copied in new table as well.
May I know what is happening here?
I have multiple data sets that drive the Pentaho report. The data is derived from a handful of stored procedures. I need to access multiple data sources within the report without using sub reports and I believe the best solution is to create open formulas. The SINGLEVALUEQUERY I believe will only return the first column or row. I need to return multiple columns.
As an example here my stored procedure which is named HEADER in Pentaho (CALL Stored_procedure_test (2014, HEADER)), returns 3 values - HEADER_1, HEADER_2, HEADER_3. I'm uncertain of the correct syntax to return all three values for the open formula. Below is what I tried but was unsuccessful.
=MULTIVALUEQUERY("HEADER";?;?)
The second parameter denotes the column that contains the result.
If you dont give a column name here, the reporting engine will simply take the first column of the result. In the case of the MULTIVALUEQUERY function, the various values of the result set are then aggregated into a array of values that is suitable to be passed into a multi-select parameter or to be used in a IN clause in a SQL data-factory.

I want to show the string value as one of the measure value. When a fact table has a integer value and string value respectively and also has some foreign table's keys. Then I could show the integer value as a measure value, but I couldn't show the string value as a measure. Because Measure element in schema of cube (written in XML) doesn't allow that a measure value doesn't have 'aggregator'(It specify the aggregate function of measure values). Of course I understood that we can't aggregate some string values. But I want to show the string value of the latest level in hierarchy.
I read following article. A figure (around middle of this page) shows a cube that contains string value as a measure value. But this is an example of Property value of Dimension table, so this string value isn't contain in fact table. I want to show the string value that contains in fact table.
A Simple Date Dimension for Mondrian Cubes
Anyone have some idea that can be shown the string value as a measure value? Or I have to edit Mondrian's source code?
I have had the same problem and solved it by setting the aggregator attribute in the measure tag to max.
e.g.
\<Measure name="Comment" datatype="String" column="comment" caption="Comment" aggregator="max"/\>
Why does it need to be a measure?
If no aggregation would naturally be applied to it and you just want the string value, it is a dimension, not a measure. Trying to force it to be a measure is not the best approach.
I think the figure you reference is just showing a drillthrough, and that the only actual
measure is Turnover. The report layout is slightly misleading in terms of dimensions and measures.
You can just use the fact table again in the schema as a dimension table if for some reason you don't want to split this out into a separate physical table.
Sounds like the string may be high cardinality to the integer, possibly 1:1. Depending upon the size of your cube, this might or might not be a performance challenge. But don't try to make it a measure.
Good luck!
