I'm kind new in this forum but I'm stuck in a problem and I need our help.
I Have one table with several lines where each line represent one project, then in another table I'll have many tasks that need to be done in each project, each task would have a percentage of at what level is, and the result of this two tables is one table where I'll have the process Id and also the percentage of accomplished with the average of the last entries of every tasks values.
I can't figured out the query that needs to be done to have the result that I want.
Can anyone help me? You can see follow the link bellow to see tables and the result that I want.

I didnt understand the colors of rows you used, but with your description, i think this is the query you are looking for:
select P.id_Proceso, P.SubProceso, avg(R.estado)
from Processos P
join Registros R
on P.ID = R.Id_processo
group by P.id_Proceso, P.SubProceso

So my basic goal is to create a database for a shopsystem, which is my task to do for my IT course. I tried to create a UPDATE-Query, that collects all the Sale Positions ("tblPosition.PositionAnzahl") ordered with a SELECT-Query and groups it by the products ordered, to have an overview about how often each product has been sold.
I want to do this to keep track of how many items are still left in the inventory.
The Query was supposed to update 1 field ("tblArtikel.ArtikelVerkauft") in my table "tblArtikel", in which all my articles and their information is stored.
However, i just found out that you cannot run UPDATE-Queries, that use SELECT-Query data, as i get a error, that says "Operation must use an updateable query".
This is the code i used for the query:
UPDATE tblArtikel as a JOIN
(SELECT p.PositionArtikelID, Sum(p.PositionAnzahl) AS SumOfPositionAnzahl
FROM tblPositionen as p
GROUP BY p.PositionArtikelID
) p
ON a.ArtikelID = p.PositionArtikelID
SET ArtikelVerkauft = p.SumOfPositionAnzahl;
Is there another way to keep track of all the Items left in my inventory, apart from doing what i did?
Here are screenshots of the 2 tables (the depending fields are circled red):
tblPositionen with field PositionAnzahl
tblArtikel with field ArtikelVerkauft
I have not worked with SQL before and only learned about it during 45 min, so ther emight be an easy way for this, but i would still appreciate every answer from you guys.
I'm using Tableau to show some schools data.
My data structure gives a table that has all de school classes in the country. The thing is I need to count, for example, how many schools has Primary and Preschool (both).
A simplified version of my table should look like this:
In that table, if I want to know the number needed in the example, the result should be 1, because in only one school exists both Primary and Preschool.
I want to have a multiple filter in Tableau that gives me that information.
I was thinking in the SQL query that should be made and it needs a GROUP BY statement. An example of the consult is here in a fiddle: Database example query
In the SQL query I group by id all the schools that meet either one of the conditions inside de IN(...) and then count how many of them meet both (c=2).
Is there a way to do something like this in Tableau? Either using groups or sets, using advanced filters or programming a RAW SQL calculated fiel?
Thanks!

PS: I add a link to my question in Tableu's forum because you can download my testing workbook there: Tableu's forum question
I've solved the issue using LODs (specifically INCLUDE and EXCLUDE statements).
I created two calculated fields having the aggregation I needed:
Then I made a calculated field that leaves only the School IDs that matches the number of types they have (according with the filtering) with the number of types selected in the multiple filter (both of the fields shown above):
Finally, I used COUNTD([Condition]) to display the amounts of schools matching with at least the School types selected.
Hope this helps someone with similar issue.
PS: If someone wants the Workbook with the solution I've uploaded it in an answer in the Tableau Forum
I am doing a beginners' SQL tutorial and I started to wonder whether a simple SQL query on this table: http://www.sqlcourse2.com/items_ordered.html could tell the number of items (also 1) which have only been purchased more items at a time, so there is no record which contains the quantity column with a value of 1 AND the item. I am really beginner at this so please try to keep it simple.
Thank you in advance!
Welcome to the fascinating world of SQL.
Well - I'm not giving you the answer, but a hint (after all, it's a training and your own thinking and finding the solution would be the best way for you to learn something new).
The way you formulate your question is somewhat puzzling.
When I combine what you ask with what is possible with SQL, the question that would make sense to me would be that you need to list (or count, I did not understand that very well) the items (or the complete rows in the table with matching item, that was not clear either), that were never sold with a quantity of 1.
If that's what you need, you will need a subselect to get all distinct items that were sold with a quantity of 1, and select the rows from your base table whose item value is not in the list you get from the subselect.
Do you need more hints?

Been rattling my brain for a while and I could not get pass how to do the SQL query that will show the relationship/connections between my two tables.
I'm working on an IT equipment inventory program. I have two tables;
SELECT serial_number, model, ship_dat, status FROM items_list
SELECT item_serial, connected-to_serial FROM connections
All items like desktops, laptops, monitors, etc are on the items_list table. To track down the relationship/connections of the items, I created the connections table. IE, Monitor with serial_number=Screen#1 is connected to a Desktop with serial_number=Serial#1. It works ok with my Window Form application because I
used a datagridview control to list all devices simple SQL query.
However, when trying to show the relationship/connection on SQL Reports I've ran out of ideas how to do it. I'm aiming to get the report look like below or something along the lines. I just need to show the connections between the items.
Thank you
You should be able to do this with a table in SSRS if that is what you are using. The query you would need to drive the table of all related items would be:
SELECT item_serial, connected-to_serial, mainItem.*, connectedItem.*
FROM connections
INNER JOIN items_list mainItem ON connections.item_serial = items_list.serial_number
INNER JOIN items_list connectedItem ON connections.connected-to_serial = connectedItem.serial_number
You can of course tailor the SELECT statement to your needs, mainItem.* and connectedItem.* will not give you the most descriptive column names. Using column aliases (found under column_alias here) you can give a more descriptive name to each column.
From here you should be able to use a table and create a row group on the main item (either name or serial number) to get the type of look you are looking to achieve here. I believe the Report Wizard actually has most of the functionality you are looking for and should handle the bulk of this. You may have to move some of the cells around to get the look you are going for though.
So, basically, I have two tables called "dadoscatalogo" and "palavras_chave", with a common field, "patrimonio" which is the primary key of "dadoscatalogo".
I'm using a servlet to connect to the database with these tables, and passing a query to search for entries based on some search criteria that's defined by the user.
Now, since the user can search for entries based on information present in both tables, I need to do an INNER JOIN, and then use WHERE to search for that info. I'm also using LIKE, because the user may pass just part of the information, and not all of it.
So, to test it all out, I tried passing it a few parameters to work with, and see how it went. After some debugging, I found out that there was some mistake in the query. But I can't seem to be able to point out exactly what it is.
Here's the test query:
SELECT dadoscatalogo.patrimonio
FROM dadoscatalogo
INNER JOIN palavras_chave
ON dadoscatalogo.patrimonio=palavras_chave.patrimonio
WHERE dadoscatalogo.patrimonio LIKE '%'
AND dadoscatalogo.titulo LIKE '%tons%'
OR palavras_chave.palchave LIKE '%programming%';
So, basically, what I'm trying to do with this query is, get all the primary keys from "dadoscatalogo" that are linked to a record with a "titulo" containing "tons", or a "palchave" containing "programming".
PS. Sorry for the names not being in English, hopefully it won't be too much of a distraction.
EDIT: Right now, the tables don't have much:
This is the dadoscatalogo table:
http://gyazo.com/fdc848da7496cea4ea2bcb6fbe81cb25
And this is the palavras_chave table:
http://gyazo.com/6bb82f844caebe819f380e515b1f504e
When they join, I'm expecting it to have 4 records, and it would get the one with patrimonio=2 in dadoscatalogo (which has "tons" in titulo), and the one with palchave=programming (which would have patrimonio=1)
As per my understanding run below query:
SELECT dadoscatalogo.patrimonio
FROM dadoscatalogo
INNER JOIN palavras_chave
ON dadoscatalogo.patrimonio=palavras_chave.patrimonio
WHERE dadoscatalogo.titulo LIKE '%tons%'
OR palavras_chave.palchave LIKE '%programming%';
