Hide a column in Grafana panel - regex

I have a query:
Select * from my table
That gives me 20 fields.
There is 3 columns that all begin with index in column name that I want to hide.
I could explicit all fields in query, but for 17 fields, it might not be the best solution.
In Options,
I use this regex, /index(.*)/
When I change the column header, I can see the header of the 3 columns is changing which means my regex is OK.
But when I change the type from String to Hidden, all my column except time disappear.
Is there something I am missing ?

How to make a existing column "unique" in PowerBI, so I can form a "one-to-many" relationsship?

I have 40 tables. One table has 20 rows, and one of the columns have 1385 distinct values.
I would like to use this in a relationship with another table.
TableName(1385 rows) Column:Name:(1385 distinct values)
But when I try to do this in Powerbi/Manage-Relations, it will only accept the option "Many-to-Many" relationship. It reports that none of the column are "Unique".
Well, the data in the column is unique. So how can I configure this column to be unique so I can use it in a "One-to-Many" relationship"?
Do I have to edit the DAX expression and put the "DISTINCT" keyword in the expression for that column? And How?
Now I have:
}, {"Columnname", Int64.Type}, {
what you can try is to perform remove duplicates in that table(i know its already contains distinct values but you can give it a try)... and/or just load the data again.
Best way would be when you group your data in the query editor. This way your table has only distinct values and you can create your relationship.
In the query designer under Home > Group By you can group after your column.
Example
Table:
Table (2):
Relationship (One to Many):
Result:
I hope this helps.

Split a column of lists into multiple columns in PowerBI

I have imported a JSON file into PowerBI and it contains a column in which the values are of type "List". I am looking to expand that column into multiple columns.
Specifically, the data contains a Sprint Name, the start date and the end date of the sprint, along with some other values associated with each sprint.
Trying to use "Expand to new rows" duplicates each sprint instance, creating a table that looks like this, duplicating each sprint instance multiple times for each associated value:
Sprint Name Value
JAN(S1Dev) 2019-01-01
JAN(S1Dev) 2019-01-13
JAN(S1Dev) {attribute}
JAN(S1Dev) {attribute}
JAN(S2Dev) 2019-01-14
JAN(S2Dev) 2019-01-31
JAN(S2Dev) {attribute}
JAN(S2Dev) {attribute}
FEB(S1Test) 2019-02-01
FEB(S1Test) 2019-02-15
... ...
I would like to do something similar to the "expand" feature, which instead creates a new column with each attribute rather than a new row. This is currently vastly increasing the size of my table for no reason, while also making the data practically un-useable. Any help would be appreciated, cheers!
I have found a very simple solution to this, but as it took me some time to figure it out I will answer my own question instead of deleting it to help others in the future...
Upon importing the JSON data into PowerBI first select "Convert to Table" to view the data as a table with editable properties.
Next, click the arrows pointing away from each other at the top of the column of Lists, and select "Extract Values".
Select a delimiter to use for concatenating values, I am choosing a comma since I know that the data contained within the list does not have any commas in it. If your data contains commas within it, choose something else. Similarly, if your data contains one of the delimiters, do not choose that as the delimiter.
It should now display a comma-separated list where it previously displayed "List" in orange text.
Now, right-click on the column and select "Split Column" then choose "By Delimiter"
Select the delimiter that you previously chose, and under "split at" select "Each occurrence of the delimiter" then click OK.
Your column should now be split into multiple columns based on the list!

Work with matrix (I can't edit visualisation)

I have this table in Power BI, But I can't do another table.
How I can do this?
Now the values are grouped by date (different fields have information under one date, next the same fields are grouped by another date)
I want the values in the columns to be grouped by field (one field has date information next to it).
Edit1:
I can't set Date on the 2nd place in the grouping
Because date is column, traffic,orders,rev,costs- are values
You need to set Date on the 2nd place in the grouping, after a field containing traffic, orders, etc.
EDIT:
You need to unpivot these columns first, for example, in PowerQuery. Use Edit Query. This results in transforming your 4 columns to 2: Attribute and Value. Attribute will be your first grouping parameter. 2nd will be Date. Value column goes to values.
If you need your source query somewhere else, you may create new query for this very report only. It is done by first right-clicking original one and selecting Reference Query, and the doing any edits. This will keep original query intact.

classic report and derived columns

I have a classic report 2 columns are coming from the table and the 3rd column is a derived column.
I want to compute the values of the 3rd column based on the value of the 2nd column like if the 2nd column value is 1 then I want to put '-' in the 3rd column if it is >1 then in the 3rd column I want to put 'More than one dates'
And I want to have filters in the 3rd column header with the values that I put, I this case '-' and 'More than one dates'
And when I select the filters I want the report to be filtered accordingly.
I have a put a screen shot of the report.
Please can anyone let me know how to accomplish this.
Any help will be more than welcome
Apex 5.1 and Firefox
Snap Shot of the Report
Your SELECT-Statement should look something like this:
select ULA_ORDER_NUMBER,
COUNT,
CASE WHEN COUNT = 1 THEN '-' ELSE 'More than one dates' END as FILTER
from YOUR_TABLE
For the filter just "double click" on the COUNT column header.
This is what it looks like:
Hope this helps you.

Splitting column values with Sybase and ColdFusion

I need to trim the date from a text string in the function call of my app.
The string comes out as text//date and I would like to trim or replace the date with blank space. The column name is overall_model and the value is ford//1911 or chevy//2011, but I need the date part removed so I can loop over the array or list to get an accurate count of all the models.
The problem is that if there is a chevy//2011 and a chevy//2010 I return two rows in my table because of the date. So if I can remove the date and loop over them I can get my results of chevy there are 23 chevy models.
I have not used Sybase in a while, but I remember its string functions are very similar to MS SQL Server.
If overall_model always contains "//", use charindex to return the position of the delimiter and substring to retrieve the "text" before it. Then combine it with a COUNT. (If the "//" is not always present, you will need to add a CASE statement as well).
SELECT SUBSTRING(overall_model, 1, CHARINDEX('/', overall_model)-1) AS Model
, COUNT(*) AS NumberOfRecords
FROM YourTable
GROUP BY SUBSTRING(overall_model, 1, CHARINDEX('/', overall_model)-1)
However, ideally the "text" and "date" should be stored separately. That would offer greater flexibility and generally better performance.
