How To Reference Items From Different Database?

Jul 20, 2005

Hi all,

I have two databases DB_External and DB_Internal.

I am writing some stored procedures (in DB_Internal) that reads from
the tables in DB_External. I execute my stored procedures from
DB_Internal.

Everytime I want to read the tables in DB_External, I have to refer to
the table as DB_External.dbo.tableName.

Is there a better way of declaring the database DB_External up front
in the stored procedure so I don't have to pre-fix "DB_External.dbo."
in all the table names?

Thanks in advance,
June Moore.

SQL Server 2012 :: Identify Sets That Have Same Items (where Set ID And Items In Same Table)

Feb 25, 2015

I am struggling to come up with a set-based solution for this problem (i.e. that doesn't involve loops/cursors) ..A table contains items (identified by an ItemCode) and the set they belong to (identified by a SetId). Here is some sample data:

SetIdItemCode
1A
1B
24
28
26
310
312
410

[code]....

You can see that there are some sets that have the same members:

- 1 and 10
- 2 and 11
- 7, 8 & 9

What I want to do is identify the sets that have the same members, by giving them the same ID in another column called UniqueSetId.

Reporting Services :: Group And Sum Items / Sub-items Into One Record

Apr 10, 2015

I'm having an issue creating a report that can group & sum similar items together (I know in some ways, the requirement doesn't make sense, but it's what the client wants).

I have a table of items (i.e. products).  In some cases, items can be components of another item (called "Kits").  In this scenario, we consider the kit itself, the "parent item" and the components within the kit are called "child items".  In our Items table, we have a field called "Parent_Item_Id".  Records for Child Items contain the Item Id of the parent.  So a sample of my database would be the following:

ItemId | Parent_Item_Id | Name | QuantityAvailable
----------------------------------------
1 | NULL | Kit A | 10
2 | 1 | Item 1 | 2
3 | 1 | Item 2 | 3
4 | NULL | Kit B | 4
5 | 4 | Item 3 | 21
6 | NULL | Item 4 | 100

Item's 2 & 3 are child items of "Kit A", Item 5 is a child item of "Kit B" and Item 6 is just a stand alone item.

So, in my report, the client wants to see the SUM of both the kit & its components in a single line, grouped by the parent item.  So an example of the report would be the following:

Name | Available Qty
--------------------------
Kit A | 15
Kit B | 25
Item 4 | 100

How I can setup my report to group properly?

Copy Items From One SQL Database To Another...

Apr 15, 2007

...such as stored procedures, tables etc.

Initially this started as a case of "doh, I should just be using one database here, not two", and I was simply wanting to copy database tables. In VS2K5 I tried as there is a right click menu option of copy when a table is selected but this doesn't work for me with any database object of any kind. So fast forward to the present...I now am attempting to deploy an app to a hosting service, 1&1.com. I am allowed only one database in my current package, which should be fine for now. So I had to combine the ASPNETDB along with 2 other databases. It took a bit of time, but I got everything done, I thought, and posted to the servers. While debugging I get an error saying a stored procedure can not be found. And it indeed is not.This really confuses me as I made the changes in VS2k5, shut down and restarted to make sure I didn't miss anything, then used SQL Server Man. Studio to make a .bak file to upload to my hosting service. It never occurred to me to verify the changes I made in VS2k5 were actually on the database when viewed there. Well, they aren't, and I have no idea why. That would be issue #1 I suppose.So after giving the background info here, what I am looking for help with is how to get the changes I am making in VS2k5 to also be present when viewed from SQL Server Man. Studio as the only means of posting a db to my hosting provider is by using a .bak file.Also, why is it a project template I download has a .mdf file I am not able to even see in SQL Server Man. Studio? I guess if I had this answer the issue would be resolved.TIARegards,Joe

Database Tree Says 'No Items' ???

Oct 30, 2001

I just started having this problem. When I log into SQL2000 enterprise manager and click on my database, the main directory tree shows up. When I click on the Database tree to display all of the different databases on the SQL server, the text 'No Items' shows up. I can not get to any databases, but I am connected to the SQL server. Does anyone have a solution for this problem?????

I have tried re-inatalling and all of the service packs.

How Do I Reference A Table In One Database From A SQL Script Running In Another Database?

Jan 5, 2007

I am construvcting a number of databases, some of which containsensitive data and most of which do not. I am attempting to handle thesecurity issues involved in protecting sensitive data in part byputting it in its own database. If the sensitive data is in a databasecalled d_SensitiveData, and in that database there is a table called't_A' (I know, not very informative, but this is only a triviallysimple example :-), and I have a script running in a database'NotSensitiveData' (i.e. there is a statement at the beginning of thescript "USE NotSensitiveData"), how do I referenece the primary key intable 'A'?I tried a variety of things like:ALTER TABLE t_nsXADD CONSTRAINT FK_PersonID FOREIGN KEY (p_idPerson)REFERENCES SensitiveData.t_A (p_idPerson);The above is, in fact, my latest attempt. Everything I tried hasfailed precisely at the point where I specify a table in a differentdatabase. So what is the trick to refering to a table in one databasewhen using another database?This will be used in a ASP.NET v3 application where one of the things Iwant to do is have the authentication provider be a different databasefrom the one used for the main application data.Does anyone know of an example I can download from the web that doesthe same sort of thing I want to try, with some discussion of securityissues involved (i.e. what I can do to harden the application and dataserver)?NB: I am an application developer, not a DBA nor a systemadministrator.ThanksTed

DB Design :: Generate A Script To Choose Only Top 10 Items From Each Table In Database?

I know how to generate scripts that would contain insert queries of all records in all tables. But how can I limit this to top 10 records only from each table?I can select "Data Only" when generating the script, but it generates insert queries for all data. How can get the script to have only top 10 record insert statements? These top 10 should be ordered by the primary key.

How To Reference A Table In A Different Database?

Apr 5, 2006

I have 2 databases in sql server. let us say database1 = db1 and database2 = db2
Now both the databases have a same table called table1 with the same fields.

IF data in db1.table1 is updated then data in db2.table2 should be updated automatically.

There are many ways we can do this. one way is to create a INSERT trigger on db1.table1.

But i would like to avoid trigger
Is there something in SQL server where I can just link table1 of db1 to db2 and delete the table1 in db2. That means db2 is using the same table that of db1.

Thanks

Invalid Object Name When Trying To Reference A Database

Mar 19, 2006

Hi There
Let me start by explaining what I am trying to achieve as there may be a better way to perform this. I have two databases and I want to refer to four tables - one in one database and three in the other in a sql select statement.
When I use the query builder in VWD I can only see tables for the database that is defined in the connection string - so therefore how do I add tables from another database? After reading a few posts I realized that all I have to do is use the syntax: database.owner.table (or [database].[owner].[table]). Unfortunately this didn't work and came up with the error "Invalid Object Name".
Assuming that I must have got the owner incorrect I used the Query Tool in SQL Server Express Edition and it worked perfectly! So my sql must be correct, but why will it not work inside VWD?
The two databases are named assessment and aspnetdb - the assessment database contains the table reviews and the aspnetdb database contains the tables TutorDetails, EmployerDetails and StudentDetails.
Here is the connection string and sql:
Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Assessment.mdf;Integrated Security=True;User Instance=True
SELECT Reviews.Programme, aspnetdb.dbo.TutorDetails.Tutor_DisplayName AS [Tutor Name],
aspnetdb.dbo.EmployerDetails.DisplayName AS [Employer Name], aspnetdb.dbo.StudentDetails.Student_DisplayName AS [Student Name]
FROM Reviews INNER JOIN
aspnetdb.dbo.StudentDetails ON Reviews.StudentID = aspnetdb.dbo.StudentDetails.Username INNER JOIN
aspnetdb.dbo.EmployerDetails ON Reviews.EmployerID = aspnetdb.dbo.EmployerDetails.UserName INNER JOIN
aspnetdb.dbo.TutorDetails ON Reviews.TutorID = aspnetdb.dbo.TutorDetails.UserName
WHERE (Reviews.ReviewID = 15)
Disregard the value of '15' in the WHERE statement as this was just put in to ensure I got some valid data back, this will be replaced with a variable eventually.
I know the sql statement works properly, I think the problem may be something to do with either the connection string - any ideas would be much appreciated.
Regards
Stuart

Connecting To Database - Object Reference Not Set Error Message

Feb 11, 2005

I've got code that on my own machine (visual studio .net 2003 and iis and sql server all exist on this box) works great. I display my test page, which loads a dropdownlist on page_load. This works great on my own machine.

When I move the code to our dev environment. Web server and database servers on separate boxes. I get the error "Object reference not set to an instance of an object" when i try to open the connection to the database. I thought it had to do with permissions and I check all through sql server and everything looks great. I then thought it was the connection string. I still haven't ruled this out, but I wrote a quick vbscript app to attach to the database and try to pull a record. The vbscript worked fine. So, the code works fine on my computer, but not on the web server. The connection does work with vbscript, but through my asp.net web app I get the "object reference" error.

All code below...

ASP.NET webpage:
private void Page_Load(object sender, System.EventArgs e)
{

if( !IsPostBack )
{
// Create a command object for the query
string mySelectQuery = "select id from vw_abcd order by ID";

SqlCommand myCommand = new SqlCommand(mySelectQuery,sqlConnection1);
sqlConnection1.Open();

DropDownList1.DataSource = myCommand.ExecuteReader(CommandBehavior.CloseConnection);
DropDownList1.DataBind();
sqlConnection1.Close();

RangeValidator1.MinimumValue = "1";
RangeValidator1.MaximumValue = DropDownList1.Items.Count.ToString();
}
}

Connection string on my machine:
workstation id=wXXXXXX01;packet size=4096;user id=testuser;password=testpass;integrated security=SSPI;data source=wXXXXXX01;persist security info=False;initial catalog=TestDB"/>

Connection string on web server:
network library=DBMSSOCN;data source=xxx.xx.xxx.xxxinstance1;user id=testuser;password=testpass;initial catalog=TestDB


vbscript:
Dim connConnection, rstresultset
strConnectionString = "driver={Sql Server};server=xxx.xx.xxx.xxxinstance1;user id=testuser;password=testpass;database=TestDB"

Set connConnection = CreateObject("ADODB.Connection")

connConnection.Open strConnectionString
Set rstresultset = createobject("ADODB.Recordset")

rstresultset.ActiveConnection = connConnection

rstresultset.Open "select id, comment from testtable", connConnection

msgbox rstresultset(0)
msgbox rstresultset.Fields(0).Value



Error message and stack trace:
Object reference not set to an instance of an object.

at System.Data.SqlClient.ConnectionPool.GetConnection(Boolean& isInTransaction)
at System.Data.SqlClient.SqlConnectionPoolManager.GetPooledConnection(SqlConnectionString options, Boolean& isInTransaction)
at System.Data.SqlClient.SqlConnection.Open()

Any ideas what's going on?????

SQL 2012 :: Unable To Add Service Reference In A CLR Database Project?

Apr 17, 2014

I created a CLR procedure with a service reference in Visual Studio 2010 that is being used in SQL Server 2008 R2. We recently tried to deploy it to a 2012 SQL Server, but were unable to due to compatibility issues. When I tried to upgrade the package to Visual Studio 2013 I got this error message:

Unable to cast object of type 'Microsoft.VisualStudio.Data.Tools.Package.Project.DatabaseFileNode' to type 'Microsoft.VisualStudio.Data.Tools.Package.Project.Internal.FolderNode'

I tried to create this using the 2012 Data Tools, but was unable to add a service reference with the GUI. It appears Microsoft has removed this functionality. My company has a third party app that we have limited control over, which is why we need this functionality.

Counting Items

Jun 22, 2004

Hi,

I'm trying to include the COUNT(*) value of a sub-query in the results of a parent query. My SQL code is:

SELECT appt.ref, (Case When noteCount > 0 Then 1 Else 0 End) AS notes FROM touchAppointments appt, (SELECT COUNT(*) as noteCount FROM touchNotes WHERE appointment=touchAppointments.ref) note WHERE appt.practitioner=1

This comes up with an error basically saying that 'touchAppointments' isn't valid in the subquery. How can I get this statement to work and return the number of notes that relate to the relevant appointment?

Cheers.

What's A Best Way Of Tagging Items?

May 13, 2008

Hey everyone,

I'm working on a document management system that will allow the users to tag docs. Would it better in terms of performance and general maintenance to have all the tags comma de-limited in a column of the doc record, or have each tag in a row of an associated table?

Thanks in advance!
