I'm trying to concatenate 3 different tables in powerBI, with powerQuery but I couldn't find the solution for it. The closest I could find is appending the query, however it does not concatenate the table shown below.
Example:
Im trying to concatenate table Code1 to Code2 to Code3 (bottom 3 tables) to look like the top one.
Thank you very much for your help
Alternate method
In Table3, add column, custom column,
= Table1
then expand
Add column, custom column
= Table2
then expand
Add a custom column to each of your queries, all with the same value. For my test I just used the value of 1.
Then merge Query 1 to Query 2 on your custom column. Next, merge that query to Query 3 again on the custom column. Once you rearrange the columns you will get an output that looks like this:

I have a DAX table "Sumtable" that calculates the the number of rows in "Maintable" for two cases: (1) all rows in Maintable and (2) the subset of rows where Cat = "A".
Sumtable = {
("Full set", COUNTROWS(Maintable)),
("Subset", COUNTROWS(FILTER(Maintable, Maintable[Cat] = "A")))
}
I want to viz Sumtable and make it respond to filter settings on Maintable. For example when I select Maintable[Sex] = "Male" the totals in Sumtable should reflect that. What is the right way to accomplish this?
For example when I select Maintable[Sex] = "Male" the totals in Sumtable should reflect that.
Just make this two measures instead of a calculated table.
If you want these measures to appear under Sometable, you can create a one-row, one-hidden-column table with two measures, instead of two calculated columns.
And when you hide all the non-measure columns on a table it becomes a "Measure Table" with a differentiated icon.

I have a Redshift table I want to alter adding a new column, which values are derived from an existing column on the table.
Basically, only adding a column "year" which extracts the year from the column "snapshot_date".
Any ideas how to achieve that? Tried following code, but it errors out.
ALTER TABLE test_schema.table_name ADD year AS ( extract(year from snapshot_date) );
I would like to get a single value from "table2.MappedValue" for every record in table1 in Power Query Editor,
I have two tables, that have a many to one relationship, table2 is just a mapping table:
table1: ID | Values
table2: ID | MappedValue
when I try Table.Column(#"table2","MappedValue"), I get a list and not a single value.
I can do that from Table tools-> New Column, but I was wondering if that is possible in Power Query Editor.
You can do this by merging queries. In the query editor go to Home tab and select table1 click on merge and merge with table2. Next step is to expand your new column by selecting the dubble arrow in the column and select the column you want.
It's probably extremely simple but I can't find an answer. I have created a new column and I would like to use the DAX syntax to fill the column with hardcoded values.
I can write this: Column = 10 and I will get a column of 10s but let's say my table has 3 rows and I would like to insert a column with [10, 17, 155]. How can I do that?
Try using DATATABLE function
Table = DATATABLE("Column Name",INTEGER,{{10},{17},{155}})
You can also put more columns with their own data if you want to, check this
https://learn.microsoft.com/en-us/dax/datatable-function
Assuming your table has a primary key column, say, ID, you could create a new table with just the column you want to manually input.
ID Value
---------
1 10
2 17
3 155
You can create this table either through the Enter Data button or create it using the DAX DATATABLE function as #Deltapimol suggests.
Once you have this table you can create a relationship to your existing table in the data model at which point you can either use this new table in your report to get the values you need or if you really need them in the existing table for some reason, you can pull them over using the RELATED function in a calculated column.
Table1 = GENERATESERIES(1, 3)
Table2 = DATATABLE(
"ID", INTEGER,
"Value" INTEGER,
{{1, 10},{2, 17},{3, 155}}
)
Now you can create a relationship from Table1 to Table2[ID] and then define a calculated column on Table1 as follows:
ValueFromTable2 = RELATED(Table2[Value])
If you don't want to create a relationship, then you could use the LOOKUPVALUE function instead in a calculated column on Table11.

I am trying to generate a calculated column B from column A. Notice that column B is basically the same rows as column A except it's offset by 2 rows. I'm trying to generate this with DAX but I don't even know where to begin. I would appreciate any help.
You can use in PowerBI the PowerQuery Editor to append a Column with 2 "null" values (as numeric type) like the example below:
append column in powerbi example
To get this result:
final result of "column B"
Think is a easy way to get what you want.
