I want to do some visualization on Tableau with AdventureWorks 2014 data but my data is not showing on Tableau. I ran the query on SQL server-it ran successfully but did not show results. I need Product Cost, Product ID and Sales reason on Tableau. Kindly help.
SQL extract
Select * from
[Production].[ProductCostHistory] as pc
inner join [Sales].[SalesOrderDetail] as sod
on pc.ProductID=sod.ProductID
inner join [Sales].[SalesReason] as sr
on pc.ModifiedDate=sr.ModifiedDate
Your query is wrong... specifically the join on SalesReason. You are going to want to look at the SalesOrderHeaderSalesReason table, and the SalesOrderHeader table at a minimum. Start with the Sales Schema and go from there.
Here's a good diagram of the Data Model for the Sales Schema (part of it). There are others out there easily found on google.
I have a MSSQL database with 3 tables: Journals, Customers, and UserAccounts.
I'm trying to query Journals for transactions per account manager. This table has a customer ID column that links to Customers.
The Customers table has a ACC_Manager column that links to UserAccounts via UserID.
Inside the UserAcounts table are first and last name columns.
So it would be
Select
Journal.amount,
Customer.name,
UserAccounts.first
From
Tables
where
Journal.ACC_manager = 'Matt'
I'm having issues joining the tables so I can query using UserAccounts.first. Could anybody help? Thanks
Try the following. I didn't get exact column names so don't just use this code without modifying it a bit to suit your specific needs:
SELECT
j.amount,
c.name,
u.first
FROM
Journals j
JOIN Customers c ON
c.customerID = j.customerID -- Exact column names?
JOIN UserAccounts u ON
u.UserID = c.ACC_Manager
WHERE
u.first = 'Matt'
You may also need to use LEFT JOIN as opposed to JOIN. Read up on JOINs to be sure.
I have a couple of tables that have data in them that I am looking to get information from. Here is the rundown....In table 1 I have bunch of columns that I am pulling data from, one of the columns is a user ID (which is a number)that was the last userID to modify a record. In table 2 I want to pull in the name of that user based on the ID that is pulled from the other table (this table has both the userID and the username).
so my final query would have the columns in table 1 as well as the username from table 2 to show that was the user to last edit the record. I assume this has to be done in a nested select statement but for the life of me I cannot come up with the correct syntax.
Can anyone help me out?
Thanks

Yes, you need a very basic join that link both tables together.
Select t1.UserID,
t2.UserName
FROM table1 t1 INNER JOIN
table2 t2 ON t1.userid=t2.userid
select t1.*, t2.{username} from table1 as t1
join table2 as t2 on t1.{userId}=t2.{userid};
change {username} with the actual column name of user
similarly {userId} with appropriate column name in tables.
Hope it helps you.
this is standard inner join query, to learn more consider reading: http://www.w3schools.com/sql/
I'll start by saying hello! This forum has been a great help to me over the past few months, but have only now joined and asking my first question.
I'm working with the Northwind database in SQL Server 2008 r2 to build a vb.net application. I've been wrecking my head for a week trying to figure out how to make an order/invoice form. I can get the information I need to display using separate stored procs (GetCustInfo, GetOrderInfo, GetProductInfo, or something like that), but I'm having trouble figuring out how to display them on the form.
When I select all the info I need in one sp (as in the Invoice view which comes built in the db), I get 2155 rows, which is the number of items which have been ordered in the company history.
What I want to do is display this information, but navigate by OrderID (which would give me 830 rows, each with a certain number of products related to the OrderID). So I'm thinking I need different stored procs related which can be related in some way.
I'd really appreciate any help that can be given on this.
Many thanks in advance.
p.s. I have screenshots of the Northwind sample app which shipped/ships with Access, which is really what I'm trying to recreate in SQL Server. Unfortunately, no code!

Yes you can achieve it by many ways and SP is one. Just create a SP to select that related products passing OrderId as a input parameter.
Some options (with contrived examples):
You can ALTER existing stored procedures to get what you want (not recommended if you want to use the existing procedures for other queries).
ALTER PROCEDURE usp_ExistingProcedure
AS
BEGIN
SELECT t1.Value
, t2.Value
-- Supose that this was the addition we made to an existing stored procedure
, t2.ValueTwo
FROM TableOne t1
INNER JOIN TableTwo t2 ON t1.ID = t2.ID
END
You can CREATE new stored procedures for your queries; in the above example, it would be a create procedure with a new name.
You may be able to create a VIEW to obtain what you need - this will operate a little differently.
CREATE VIEW uv_ApplicationView
AS
SELECT t1.Value
, t2.Value
, t2.ValueTwo
FROM TableOne t1
INNER JOIN TableTwo t2 ON t1.ID = t2.ID
You can pull the query directly from the VB application, though if you want to reuse it for something else, I wouldn't recommend this approach.
// A re-usable approach calling a stored procedure
SqlCommand myQuery = new SqlCommand("EXECUTE usp_myQuery", sqlConn);
// A query directly in the C# code:
string msQuery = "SELECT t1.Value, t2.Value, t2.ValueTwo FROM TableOne t1 INNER JOIN TableTwo t2 ON t1.ID = t2.ID"
// Later ...
SqlCommand myQuery = new SqlCommand(msQuery, sqlConn);
In SharePoint 2003 there is a table called "AllUserData" which is used to store data for all lists and documents: http://msdn.microsoft.com/en-us/library/dd358229(v=PROT.13).aspx
I'm interested in 3 main columns in this table:
tp_ContentType
tp_DirName
tp_LeafName
In SharePoint 2010, this table exists; however, the above columns are removed or moved somewhere else.
Where could I find those columns associated with a sharepoint list/document in SharePoint 2010? To which table have they been moved?
I appreciate this requires proper understanding of the SharePoint 2010 database schema.
(reading from database structure directly is not the recommended approach, I know; just please answer my question if you can.)
What I tried was to find out the list of columns with a similair names with the below script:
select b.name as ColumnName, a.name as TableName
from sysobjects a
join syscolumns b
on a.id = b.id
where a.type = 'u' and
((b.name like '%dir%')) or (b.name like '%leaf%') or (b.name like '%contenttype%'))
order by 2
It returned some tables and columns but I'm not sure this is the right way to find those.
I couldn't find any documentation about this either?
Hope the question is clear.
Thanks,
