I am new to PowerBI and trying to append 2 queries into new query. But it is repeating data from the first query set and not creating an Append(I think i am correct if it is same as UNION in SQL). Here are the snapshots:
Query1
Query2
Resulting Append
Let me know what is wrong in this
Regards
In your data set it is doing a Union on the data as you mentioned. Append in Power Query will NOT remove duplicates (like a UNION ALL in SQL), you will have to use a 'Group By' step or 'Remove Duplicates' step after the append to remove the duplicates
Hope that helps
Go to Edit Queries and select your Query1 then go to Home > Append Queries as New. Chose your two tables (Query1 and Query2) and hit OK.
This should exactly append the two queries, without repeating any duplicates.

I have an interactive grid which has a dynamic action to fetch returns from another table
begin
for c in (select
REW_SIZE,
IN_STOCK,
DESCRIPTION,
FINANCIAL_YEAR_ID
into
:REW_SIZE,
:IN_STOCK,
:DESCRIPTION,
:FINANCIAL_YEAR_ID
from
T_SORDER_PROFOMA_REWINDING
where so_id = :so_id)
loop
:REW_SIZE := c.REW_SIZE;
:IN_STOCK :=c.IN_STOCK;
:DESCRIPTION:=c.DESCRIPTION;
:FINANCIAL_YEAR_ID:=c.FINANCIAL_YEAR_ID;
end loop;
end;
When I had simple select into query, it gave "exact fetch returns more than requested number of rows" thn I applied the above code but it returns only 2nd row. I have 2 rows in the table for this ID.
For what I understand, you want to get some extra data columns. Your best shot is to create a view to join these table and deliver the columns you need. If you need editing, you will have to create an instead of trigger on the view as well, to do a correct dml on one or both tables.
create view which joins both tables
create instead of trigger (if you need editing)
query of the Interactive Grid should be on the view
This solution adds the extra data columns to the source of the IG, which is better and easier in my opinion.
I have the following query in M:
= Table.Combine({
Table.Distinct(Table.SelectColumns(Tab1,{"item"})),
Table.Distinct(Table.SelectColumns(Tab2,{"Column1"}))
})
Is it possible to get it working without prior changing column names?
I want to get something similar to SQL syntax:
select item from Tab1 union all
select Column1 from Tab2
If you need just one column from each table then you may use this code:
= Table.FromList(List.Distinct(Tab1[item])
& List.Distinct(Tab2[Column1]))
If you use M (like in your example or the append query option) the columns names must be the same otherwise it wont work.
But it works in DAX with the command
=UNION(Table1; Table2)
https://learn.microsoft.com/en-us/dax/union-function-dax
It's not possible in Power Query M. Table.Combine make an union with columns that match. If you want to keep all in the same step you can add the change names step instead of tap2 like you did with Table.SelectColumns.
This comparison of matching names is to union in a correct way.
Hope you can manage in the same step if that's what you want.
I have the following tables:- evaluations, evaluation_options and options. I am trying to create an evaluation and evaluation_option on one page.
To create the evaluation_option I will need evaluation_id after an evaluation is created. I am getting the option_id from a List of Value.
At this point, I am not sure how to get this done as I am new to PL-SQL & SQL.
For this, I did a dynamic query to create both tables. I don't think this is the best way of getting the job done, I am open up to resolve this in the right way.
This is my code:-
DECLARE
row_id evaluations.id%TYPE;
BEGIN
INSERT INTO EVALUATIONS (class_student_rotations_id, strengths,
suggestions) VALUES (:P12_CLASS_STUDENT_ROTATIONS_ID, :P12_STRENGTHS,
:P12_SUGGESTIONS);
SELECT id into row_id FROM EVALUATIONS WHERE ROWID=(select max(rowid)
from EVALUATIONS);
INSERT ALL
INTO evaluation_options (option_id, evaluation_id) VALUES
(:P12_APPLICATION_OF_BASICS, row_id)
SELECT * FROM DUAL;
END;
In my model I have table AssignedToUser that don't contain any NULL values.
Table TotalCounts contains number of tasks for each User.
Those two table joined on UserGUID, and table TotalCounts contains NULL value for UserGUID.
When I drop everything in one table there is NULL value for AssignedToUser.
How can I substitute value NULL for AssignedToUser for "POOL".
Under EditQuery I tried to Create additional column
if [AssignedToUser] = null then "POOL" else [AssignedToUser]
But that didnt help.
UPDATE:
Thanks Alexis.
I have created FullAssignedToUsers table, but when I try to make a relationship with TotalCounts on UserGUID - it doesnt like it.
Data in new a table looks like this:
UPDATE:

I believe the problem here is that your join has UserGUID values that are not in your AssignedToUsers table.
To correct this, one possibility is to replace your AssignedToUsers table with one that contains all the UserGUID values from the TotalCounts table.
FullAssignedToUsers =
ADDCOLUMNS(VALUES(TotalCounts[UserGUID]),
"AssignedToUser",
LOOKUPVALUE(AssignedToUsers[AssignedToUser],
AssignedToUsers[UserGUID], TotalCounts[UserGUID]))
The should get you the full outer join. You can then create the custom column like you described in the table and use that column in your visual.
You'll probably want to break the relationships with the original AssignedToUsers table and create relationships with the new one instead.
If you don't want to take that extra step, you can do an ISBLANK inside your new table formula.
FullAssignedToUsers =
ADDCOLUMNS(VALUES(TotalCounts[UserGUID]),
"AssignedToUser",
IF(
ISBLANK(
LOOKUPVALUE(AssignedToUsers[AssignedToUser],
AssignedToUsers[UserGUID], TotalCounts[UserGUID])),
"POOL",
LOOKUPVALUE(AssignedToUsers[AssignedToUser],
AssignedToUsers[UserGUID], TotalCounts[UserGUID])))
Note: This is equivalent to doing a right outer join merge on the AssignedToUsers table in the query editor and then replacing the nulls with "POOL". I'd actually recommend approaching it that way instead.
Another way to approach it is to pull the AssignedToUser column over to the TotalCounts table in a custom column and use that column in your visual instead.
AssignedToUsers =
IF(ISBLANK(RELATED(AssignedToUsers[AssignedToUser])),
"POOL",
RELATED(AssignedToUsers[AssignedToUser]))
This is equivalent to doing a left outer join merge on the TotalCounts table in the query editor, expanding the AssignedToUser column, then replacing nulls with "POOL" in that column.
In Dax missing values are Blank() not null. Try this:
=IF(
ISBLANK(AssignedToUsers[AssignedToUser]),
"Pool",
AssignedToUsers[AssignedToUser]
)
How do I do the equivalent of
SELECT *, id=1 AS calc_column FROM table
in Korma? (Obviously, id=1 is just a simple example).
Korma has sqlfn which can be used in fields as show here. If even that doesn't fit your need then you always have the raw function to feed in raw sql in main query.
