I would like to show data as a single row instead of multiple rows.
For example, a certain user has two status associated, like maybe "Pending Approval" and "Waiting Email Verfication". Instead of showing these statuses on two different rows, I would like to show as one row.
John Smith Pending Approval
John Smith Waiting Email Verfication
John Smith Pending Approval, Waiting Email Verfication
There could such multiple states for this user, but all show in one row.
Declare @t table([Name] varchar(20),[Status] varchar(50))
insert into @t values
('John Smith','Pending Approval'),('John Smith','Waiting Email Verfication')
--,('User2','Pending Approved'),('User2','Sent email'),('User2','Other activity')
--Select * from @t
select Result = [Name] + ' ' + Stuff((Select ',' + CAST([Status] as varchar(100)) from @t t2 where t1.[Name]
= t2.[Name] for XML Path('')),1,1,'')
from @t t1
group by t1.[Name]
John Smith Pending Approval,Waiting Email Verfication
I wondered if Sql Server supported somehow to do that?
By that, I mean having the structure on one database and the data on another.
The purpose is to be able to lunch a set of integration tests that would get the data on the test database but would execute the stored procedures from the original database.
I didn't found much on google, so I suppose this isn't possible.
Edit: I didn't said, that I'd like to leave the stored procedures as they are, prefixing table names with a database would be too much work. Ideally it should be a config parameter or something like that.
The stored procedure is executed on a server not a database. You can have
multiple databases on one server.
Not so sure about that, I may be wrong though.
We have multiple databases in one single server, indeed, but some databases contain some procedures and other databases contain other procedures, so I'd say that the database is the procedure's owner.
Anyway, linked servers may be a solution indeed, but it would require to prefix the table names with the server/database name. We actually have too many stored procedures, so this is not an option right now.
If you try running a stored procedure that stores to the c:\ drive, see where the file ends up. Now there is most likely a way to change behavior of where a process runs but I use the defaults. See sp_who also will show you what is running on a given server.
You can run a stored procedure from one linked server on another by using the server/database name. Within a stored procedure I like to have the database with the table so if it is ran from another database it still runs. I think this is called fully qualified but I do not remember. But database.schema.table is what I suggest and with the new schema importance in 2005/2008 referencing the schema should be the minimum. (We still currently use dbo for our tables though).
If you try running a stored procedure that stores to the c:\ drive, see where
the file ends up.
Are you talking about Sql Server, or Windows Server? Checking the location of a file stored from a stored procedure makes me believe you are talking about the second one.
If you have an Sql Server that has two databases, db1 and db2, and you create a Stored Procedure only on db2, trying to run that stored procedure from db1 won't work.
Check the details of EXEC sp_who you'll see that the dbname is specified.
We too are referencing the schema, and we still use dbo too by the way.
I think that the only way would be prefixing all our table/views/etc. calls with the database name, the name should be a parameter (if we're running tests then the data should be retrieved from the test database, otherwise it should get the data from the context's database). If we use a parameter, then, that would mean converting all our procedures to dynamic sql. Considering that we almost have 3000 stored procedures, this is not an option, as said before.
I was wondering if Sql Server supported some sort of parameter, indicating that it should read the data from another database, while executing a procedure from another (without having to edit the stored procedures, this is a key factor).
If the synonym is on the test server and points to the code on the production server then any change to the prod server should immediately be available to the test server. You run the code on the test server but it is the code from production.
Or am I not seeing the problem?
Give a man a mug, he drinks for a day. Teach a man to mug...
USE tempdb;<br />
-- Create a synonym for the Product table in AdventureWorks2008R2.<br />
CREATE SYNONYM MyProduct<br />
FOR AdventureWorks2008R2.Production.Product;<br />
-- Query the Product table by using the synonym.<br />
USE tempdb;<br />
SELECT ProductID, Name <br />
FROM MyProduct<br />
WHERE ProductID < 5;<br />
Maybe I'm not seeing it, but how would you manage to use the same procedure and call different databases depending on who called the procedure?
Let's say we have db1 and db2 and we're doing:
SELECT A, B, C FROM dbo.Table
What I need is to call the data from db1 if the application made the call, but go read the data on db2 if the call was made by the build server (the unit/integration tests).
