Currently, I have two CSV datasets in Tableau Dashboard as below:
Table A:
Account_Number
ID
AN_1
ID_1
AN_2
ID_2
Table B:
ID
Full_Name
ID_1
Name_1
ID_2
Name_2
I want to merge the two tables so that it can become:
Account_Number
Full_Name
AN_1
Name_1
AN_2
Name_2
How can I do that using SAQL in Tableau? Many thanks!
Work-around: It seems that there is no option to perform INNER_JOIN like in SQL, so I am currently stuck. I have messed around with group by and replace but all not working like what I expected...

I'm using Access 2016 to view data from a table on our SQL server. I have a massive audit log where the record being viewed is represented by a "FolderID" field. I have another table that has values for the FolderID (represented as "fid") along with columns identifying the record's name and other ID numbers.
I want to be able to replace the FolderID value in the first table with CUSTOMER_NAME value from the second table so I know what's being viewed at a glance.
I've tried googling different join techniques to build a query that will accomplish this, but my google-fu is weak or I'm just not caffeinated enough today.
Table 1.
EventTime EventType FolderID
4/4/2019 1:23:39 PM A 12345
Table 2
fid acc Other_ID Third_ID CUSTOMER_NAME
12345 0 9875 12345678 Doe, John
Basically I want to query Table 2 to search for fid using the value in Table 1 for FolderID, and I want it to respond with the CUSTOMER_NAME associated with the FolderID/fid. The result would look like:
EventTime EventType FolderID
4/4/2019 1:23:39 PM A Doe, John
I'm stupid because I thought I was too smart to use the freaking Query Wizard. When I did, and it prompted me to create relationships and actually think about what I was doing, it came up with this.
SELECT [table1].EventTime, [table1].EventType, [table1].FolderID, [table1].ObjRef, [table1].AreaID, [table1].FileID, [table2].CUSTOMER_NAME, [table2].fid FROM [table2]
LEFT JOIN [table1] ON [table2].[fid] = [table1].[FolderID];
You can run this query and check if it helps!.
Select EventTime, EventType , CUSTOMER_NAME AS FolderID FROM Table1, Table2 Where Table1.FolderID = Table2.fid;
Basically, 'AS' is doing what you want here as you can rename your column to whatever you want.
I have a question in regards to adding data to a particular column of a table, i had a post yesterday where a user guided me (thanks for that) to what i needed and said an update was the way to go for what i need, but i still can't achieve my goal.
i have two tables, the tables where the information will be added from and the table where the information will be added to, here is an example:
source_table (has only a column called "name_expedient_reviser" that is nvarchar(50))
name_expedient_reviser
kim
randy
phil
cathy
josh
etc.
on the other hand i have the destination table, this one has two columns, one with the ids and the other where the names will be inserted, this column values are null, there are some ids that are going to be used for this.
this is how the other table looks like
dbo_expedient_reviser (has 2 columns, unique_reviser_code numeric PK NOT AI, and name_expedient_reviser who are the users who check expedients this one is set as nvarchar(50)) also this is the way this table is now:
dbo_expedient_reviser
unique_reviser_code | name_expedient_reviser
1 | NULL
2 | NULL
3 | NULL
4 | NULL
5 | NULL
6 | NULL
what i need is the information of the source_table to be inserted into the row name_expedient_reviser, so the result should look like this
dbo_expedient_reviser
unique_reviser_code | name_expedient_reviser
1 | kim
2 | randy
3 | phil
4 | cathy
5 | josh
6 | etc.
how can i pass the information into this table? what do i have to do?.
EDIT
the query i saw that should have worked doesn't update which is this one:
UPDATE dbo_expedient_reviser
SET dbo_expedient_reviser.name_expedient_reviser = source_table.name_expedient_reviser
FROM source_table
JOIN dbo_expedient_reviser ON source_table.name_expedient_reviser = dbo_expedient_reviser.name_expedient_reviser
WHERE dbo_expedient_reviser.name_expedient_reviser IS NULL
the query was supposed to update the information into the table, extracting it from the source_table as long as the row name_expedient_reviser is null which it is but is doesn't work.
Since the Names do not have an Id associated with them I would just use ROW_NUMBER and join on ROW_NUMBER = unique_reviser_code. The only problem is, knowing what rows are null. From what I see, they all appear null. In your data, is this the case or are there names sporadically in the table like 5,17,29...etc? If the name_expedient_reviser is empty in dbo_expedient_reviser you could also truncate the table and insert values directly. Hopefully that unique_reviser_code isn't already linked to other things.
WITH CTE (name_expedient_reviser, unique_reviser_code)
AS
(
SELECT name_expedient_reviser
,ROW_NUMBER() OVER (ORDER BY name_expedient_reviser)
FROM source_table
)
UPDATE er
SET er.name_expedient_reviser = cte.name_expedient_reviser
FROM dbo_expedient_reviser er
JOIN CTE on cte.unique_reviser_code = er.unique_reviser_code
Or Truncate:
Truncate Table dbo_expedient_reviser
INSERT INTO dbo_expedient_reviser (name_expedient_reviser, unique_reviser_code)
SELECT DISTINCT
unique_reviser_code = ROW_NUMBER() OVER (ORDER BY name_expedient_reviser)
,name_expedient_reviser
FROM source_table
it is not posible to INSERT the data into a single column, but to UPDATE and move the data you want is the only way to go in that cases
I am trying to build a temp table with grouped data from multiple tables (in an SP), I am successful in building the data set however I have a requirement that each grouped row have a unique id. I know there are ways to generate unique ids for each row, However the problem I have is that I need the id for a given row to be the same on each run regardless of the number of rows returned.
Example:
1st run:
ID Column A Column B
1 apple 15
2 orange 10
3 grape 11
2nd run:
ID Column A Column B
3 grape 11
The reason I want this is because i am sending this data up to SOLR and when I do a delta I need to have the ID back for the same row as its trying to re-index
Any way I can do this?
Not sure if this will help, not entirely confident of your wider picture, but ...
As your new data is assembled, log each [column a] value in a table of your own.
Give that table an IDENTITY column to do the numbering for you.
Now you can join any new data sets to your lookup table and you'll have a persistent number for each column A.
You just need to ensure that each time you query new data, you add new values to the lookup table.
create table dbo.myRef(
idx int identity(1,1)
,[A] nvarchar(100)
)
General draft as below ...
--- just simulating some input data here
with cte as (
select 'apple' as [A], 15 as [B]
UNION
select 'orange' as [A], 10 as [B]
UNION
select 'banana' as [A], 4 as [B]
)
select * into #temp from cte;
-- Put any new values into the lookup table
-- and they will be assigned a new index number by the identity column
insert into dbo.myRef([A])
select distinct [A]
from #temp where [A] not in (select [A] from dbo.myRef)
-- now pull your original data for output, joining to the lookup table to get a ref number.
select T.*,R.idx
from #temp T
inner join
oer.myRef R
on T.[A] = R.[A]
Sorry for the late reply, i was stuck with something else, however i solved my own issue.
I built 2 temp tables one with all the data from the various tables (#master) and another temp table (#final) to house all the grouped data with an empty column for ID
Next i did a concat(column1, '-',column2,'-', column3) on 3 columns from the #master and updated the #final table based on the type
this helped me to get the same concat ids on each run
I am trying to create one spx which based upon my ID which is 1009 will move 9 columns data to new table:
The old table has 9 columns:
CD_Train
CD_Date
CD_Score
Notes_Train
Notes_Date
Notes_Score
Ann_Train
Ann_Date
Ann_Score
userid - common in both tables
ID - 1009 - only exists in this table
and my new table has:
TrainingID,
TrainingType,
Score,
Date,
Status,
userid
TrainingType will have 3 values: Notes, CD, Ann
and other fields like score will get data from notes_score and so on
and date will get data from notes_date,cd_date depending upon in which column cd training went
status will get value from Notes_Train, cd_train and so on
based upon this, I am lost how should I do it
I tried querying one sql of users table and tried to do the join but I am losing the ground how to fix it
No idea yet, how to fill your column trainingId but the rest can be done by applying some UNION ALL clauses:
INSERT INTO tbl2 (trainingType,Date,Score,Status,userid)
Select 'CD' , CD_date, CD_score, CD_Train, userid FROM tbl1 where CD_date>0
UNION ALL
SELECT 'Notes', Notes_Date, Notes_Score, Notes_Train, userid FROM tbl1 where Notes_date>0
UNION ALL
SELECT 'Ann', Ann_Date, Ann_Score, ANN_Train, userid
FROM tbl1 where Ann_date>0
I don't know as yet whether all columns are filled in each row. That is the reason for the where clauses which should filter out only those rows with relevant data in the three selected columns.
I'm handling this problem here in company: We have different customers, that need different fields in the same table, but we do not want to have a table with 300 columns, which is inneficient, hard to use and so on. Example:
table_products have this fields: product_id, product_name, product_cost.
then, the first client 'X' needs the field product_registerid.
the client 'Y' needs the field product_zipareaid.
That happens by different causes. Example: they are from different states, that have different rules.
At this moment we came up with this solution, which i don't like:
product_id, product_name, product_cost, product_personal. In this product_personal we have saved values like '{product_registerid:001;product_zipareaid:001-000131}'.
I came up with a theoretic solution: extend the table, and the sql will know when i do a query in the extended table, and shou me the column with the main table's column. Something like:
table_products with columns product_id, product_name, product_cost.
table_products_x with column product_registerid.
table_products_y with column product_zipareaid.
And the querys would return:
1.
select * from table_products where product_registerid = 001:
product_id, product_name, product_cost, product_registerid
1, iphone, 599, 001.
2.
select * from table_products where product_zipareaid = 000-000110:
product_id, product_name, product_cost, product_zipareaid
1, iphone, 599, 000-000110.
So, im accepting different suggestions for solving our problem.
Thank you in advance!
One approach would be to add a single Extended Properties table, that would look something like this:
Product_id (FK)
Client_id
PropertyName
PropertyValue
And so it would be populated with values like:
Product_id Client_id PropertyName PropertyValue
1 x product_registerid 001
1 y product_zipareaid 000-000110
Then you just join table_products to Extended_properties on Product_Id and put the Client_id(s) you want in the WHERE clause.
Note that you'll probably end up wanting to use a PIVOT query to get multiple extended properties for each client.
