End user column sort - PowerBi - dynamic

Wanted to know if there is a way where the end user can custom sort a column
For example we can add a conditional column sort like below and can use 'sort by column' option to custom sort a column. Is there a way where we can add a parameter in M and end user can switch between different sorting for the column? For example if he
Zone |Sort
North | 1
South | 2
Central | 3
East | 4
West | 5
There is a new Dynamic M query parameter in preview in power bi march update but couldn't make it to work
If it cannot be achieved via parameters then what would be the best approach?

Returning a value based on multiple conditions in excel

Consider the following data:
Item | Overall | Individual | newColumn
A | Fail | Pass | blank
A | Fail | Fail | blank
B | Fail | Pass | issue
B | Fail | Pass | issue
C | Pass | Pass | blank
I have the logic built out for the first 3 columns already. There are two levels of fails in this data:
overall, and
individual.
If any of the individual fail, the overall fails. Sometimes the overall can fail even though all the individuals are fine. This logic is already built out.
I am trying to find a formula for the newColumn. If all the individuals are a pass for a given item (example item B), but the overall is still a fail, the cell should return the text "issue". It is ok if it returns issue twice, not sure if you can non-dupe that part. I've tried various forms of countifs/and/ors and creating columns that count distinct values but I always find a scenario where it will break the logic.
Try this:
=IF(COUNTIFS($A$2:$A$6,A2,$C$2:$C$6,"Fail"),"blank",IF(B2="Fail","Issue","blank"))
As required
If you add a new column with the formula:
=IF(B2="Fail",IF(COUNTIFS(A:A,A2,C:C,"fail")=0,"issue",""),"")
Then this should work on the assumptions:
For each item if one of the overalls are false they are all false
The only two possible values are "Pass" and "Fail" for columns B & C
If you require the word blank instead of a blank cell then use:
=IF(B2="Fail",IF(COUNTIFS(A:A,A2,C:C,"fail")=0,"issue","blank"),"blank")

Matrix in SQL/VB.net

i have a Datagrid that stores the number pencils produced each day of the month it looks like this:
Pencil | day 1 | day 2 | day 3 | ... |day 31
Red 0 0 13 0 0
blue 5 1 0 8 0
yellow 0 9 5 0 0
I need to save this data into SQL table but im not sure what's the most efficent way to design the table in SQL.
I was thinking about creating a table in SQL with the fields:
pencilmodel
date
quantity
and then in vb.net making a loop that saves 1 by 1 each cell of the datagrid in to the table, but i dont think this is the best way since i will have like 30 rows and a month has 31 days max so it will be 30*31= 930 times.
Im using VB.net and SQL Server
i would create the table that way (as you suggested):
ID | pencilmodel | ProducedDate | Quantity
1 blue dd-mm-yyyy 7
2 red dd-mm-yyyy 4
3 yellow dd-mm-yyyy 6
also, dont loop and insert each row to database, its not efficient, add it to a dataset first and then update it using DataAdapter.Update or bind a dataset to the datagrid view:
How to: Bind Data to the Windows Forms DataGridView Control
I dont know if this one is relevant but why dont you create a fields based on the date and time? lets say like this in your PC
12/14/2016
You can create a program that will create a field for you everyday for example when the day passes by then add a column look like this.
__________________________________
|12/14/2016|12/15/2016|12/15/2016|
so what will happen is you dont need to loop in DGV you just do your INSERT COMMAND
you just need some modifications and validations in here like
if Date_Has_Been_Changed then
Create Table Add Columns
End If

Value to table header in Pentaho

Hi I'm quite new in Pentaho Spoon and I have a problem:
I have a table like this:
model | type | color| q
--1---| --1-- | blue | 1
--1---| --2-- | blue | 2
--1---| --1-- | red | 1
--1---| --2-- | red | 3
--2---| --1-- | blue | 4
--2---| --2-- | blue | 5
And I would like to create a single table (to export in csv or excel) for each model grouped by type with the value of the group as header and as value the q value:
table-1.csv
type | blue | red
--1--| -1-- | -1-
--2--| -2-- | -3-
table-2.csv
type | blue
--1--| -4-
--2--| -5-
I tried with row denormalizer but nothing.
Any suggestion?
Typically it's helpful to see what you have done in order to offer help, but I know how counterintuitive the "help" on this step is.
Make sure you sort the rows on Model and Type before sending them to the denormalizer step. Then give this a try:
As for splitting the output into files, there are a few ways to handle that. Take a look at the Switch/Case step using the Model field.
Also, if you haven't found them already, take a look at the sample files that come with the PDI download. They should be in ...pdi-ce-6.1.0.1-196\data-integration\samples. They can be more helpful than the online documentation sometimes.
Row denormalizer can't be used here if number of colors is unknown, also, you can't define text output fields dynamically.
There are few ways that I can see without using java and js steps. One of them is based on the following idea: we can prepare rows with two columns:
Row Model
type|blue|red 1
1|1|1 1
2|2|3 1
type|blue 2
1|4 2
2|5 2
Then we can prepare filename for each row using Model field and then easily output all rows using text output where file name is taken from filename field. In this case all records will be exported into two files without additional efforts.
Here you can find sample transformation: copy-paste me into new transformation
Please note that it's a sample solution that works only with csv. Also it works only if you have the same number of colors for each type inside model. It's just a hint how to use spoon, it's not a complete solution.

Generate automatically all the variables and value labels in SPSS

I have the variable labels and value labels in a table in my database, like this
id_variable_label | variable_label | id_value_label | value_label | id_father_label
---------------------------------------------------------------------------------------------------------
1 | father_label | null | null | null
null | father_label | 1 | child01 | 1
null | father_label | 2 | child02 | 1
Is there a way to generate automatically all the variables and value labels when I import the data from my database through a ODBC connection?
There isn't a direct way to do this, but if you read that table as an SPSS dataset, it would be pretty simple to generate the labels with a little Python code.
Note also that if your labeling is static, you can use APPLY DICTIONARY to copy labels from one dataset to another, so saving one fully labeled file would allow you to propagate that to others that are similarly structured.
You can use SPSS syntax to create variable and value labels.
See the SPSS commands VARIABLE LABELS and VALUE LABELS.
Here's a tutorial here that explains how you can use them.
You could generate the syntax from your database.

Highlighting Values in a Crystal Reports Crosstab based on sibling values

I have crosstab which has row columns indicating different classes, and then peoples names across the top.
| | Required | Person 1 | Person 2 | Person 3 |
| Class 1 | 8 6 | 1 6 | 3 6 | 4 6 |
| Class 2 | 6 2 | 3 2 | 2 2 | 1 2 |
Each field contains 2 values The first value is the number of hours spent in the class, the second field is the number of hours required for certification.
The Required field id my grand total summary.
In the cross tab expert the fields are defined as follows.
Rows:
Command.descr -> a field containing the class names
Columns:
Command.fullname -> a field containing students full names
Summarized Fields:
Sum of Command.evlength -> summation of all time spent in a given course
Max of #required -> this formula returns the number of required hours based on the course name
I am trying to highlight the field Sum of Command.evlength if it is greater than or equal to the value of Max of #required.
My solution was to perform background formatting. Right-Click on the Sum of Command.evlength field, select Format Field. Click the borders tab, check Background, and enter a formula.
The formula I was using is:
if CurrentFieldValue >= {#required} then color(152, 251, 152) else crNoColor
This is not the correct formula. My crosstab has been placed in the footer, which causes {#required} to contain the last value in the grid which in the above example is 2.
From my research I thought I would have to use GridRowColumnValue(row or column name) to access the value of {#required} in the crosstab, but I could not come up with the correct string to represent it.
Does anyone have a way for me to correctly perform this comparison?
Frustratingly I don't think you can use the highlighting expert to compare to a dynamic value. You could swap the columns round then add the following formulas:
To the max_of_required background colour:
whileprintingrecords;
global numbervar required_hrs := currentfieldvalue;
crNoColor;
To the sum_of_command.evlength background colour:
whileprintingrecords;
global numbervar required_hrs;
if currentfieldvalue >= required_hrs then
crRed
else
crNoColor;
I think there are a few other ways but i'm not as confident with those so start here.
