How do I define a relationship using SQL Server Management Studio?
I can create a view and drag columns between tables easily enough. Is there a way to do this with tables and not views?
Any help appreciated.
Thx
Hi,I have a table with uniqueidentifier column as its primary key. If I insert a record into this table by defining the key of this record in VB code (Dim myId As Guid = Guid.NewGuid ... is it??), is it possible that I receive the primary key violation error since the new record has an id which is already exists in the table? Thanks in advance

Hello
I have this 3 tables, Customer, Transaction and Book. Since a customer can buy the same book more than one time, I've defined Transaction_Nr as primary key of Transaction and put Customer_Nr and Book_Nr as foreign keys. So the layout is more or less like this :
Customer {Customer_Nr, Customer_Name}
Transaction {Transaction_Nr, Date, Book_Nr, Customer_Nr}
Book {Book_Nr, Book_Name}
So now my question is, would it have been better, to define Transaction_Nr, Book_Nr and Customer_Nr as a combined primary key or to leave Transaction_Nr alone ? What would be the difference ?
Thanks !
Hi All,
I have two tables.First is CAT_TABLE_LIST ;FIELD_NAME OPPOSITE_NAME TBL_NAMEHeight (mm) COL_1 TBL_13Cylinder volume (cm³) COL_5 TBL_13Torgue (daN.m) COL_7 TBL_13Cylinder weight(kg) COL_13 TBL_13Pump Type COL_9 TBL_13Fuel Consumption Col_22 TBL_22Color Col_41 TBL_09--------------------------------------------------------------------Second is TBL_13 (there are a few tables for each distict value for CAT_TABLE_LIST.TBL_NAME column );STOCK_CODE COL_1 COL_5 COL_7 COL_13 COL_9FC-25 12,5 5 15.000 45 DP 75FT-45 27 9 40.000 35 DP 101--------------------------------------------------------------------the CAT_TABLE_LIST.TBL_NAME holds relevant table name and CAT_TABLE_LIST.OPPOSITE_NAME holds columns names of that relavant table.The issue is, the columns of relevant tables dynamicly created. I mean if i insert new row to CAT_TABLE_LIST like that;INSERT INTO CAT_TABLE_LIST ('Size(USA)','Col_77','TBL_13')the new column will created for TBL_13 ;ALTER TABLE TBL_13 ADD Col_77 VARCHAR(200)And if i delete a row from CAT_TABLE_LIST, in the same transaction the column will droped from relevant table, as followsDELETE CAT_TABLE_LIST WHERE TBL_NAME ='TBL_13' AND OPPOSITE_NAME='Col_77'goALTER TABLE TBL_13 DROP COLUMN Col_77--------
Expected select query result is (for TBL_NAME = 'TBL_13' AND STOCK_CODE ='FC-25' ) .....STOCK_CODE OPPOSITE_NAME FIELD_NAME VALUEFC-25 COL_1 Height (mm) 12,5FC-25 COL_5 Cylinder volume (cm³) 5FC-25 COL_7 Torgue (daN.m) 15.000FC-25 COL_13 Cylinder weight(kg) 45FC-25 COL_9 Pump Type DP 75------------------------------------------------------------------------------How can i get this result ?

Hi there,
I'm trying to follow Lesson 1 for using XML Data in a Report here: http://msdn2.microsoft.com/en-us/library/ms345338.aspx
When I go to my local wsdl I see that the target namespace is:
http://schemas.microsoft.com/sqlserver/2005/06/30/reporting/reportingservices
I create my datasource to point to my local asmx and tested it by going directly to the URL which worked. I then create a dataset in my report which points to this datasource and has this as the query string:
<Query>
<SoapAction>http://schemas.microsoft.com/sqlserver/2005/06/30/reporting/reportingservices/ListChildren</SoapAction>
</Query>
I've created 2 parameters - Item (/) and Recursive (1).
When I try and execute the query, I get the following error:
An error occured while executing the query.
Error while reading xml response.
Error while reading xml response. (Microsoft.ReportingServices.DataExtensions)
Any help would be appreciated. Thanks.
Now, I don't know if what I want to do is possible, but here goes. In the table I want to query, there is an "approval status" column, of type Int32. There are four approval levels, 1, 2, 3 and 4. What I want to set up is a query in the table adapter that can return all entries of one or more approval levels. In "raw" sql, I would do something like: SELECT * FROM facility_table WHERE (approved IN (1,2,3));What I want to do though, is to have the list of approval codes to be a parameter that I can pass to the table adapter query, so the where clause becomes "WHERE (approved IN (@approval))", and I pass a string with the list of approval codes. But the query designer doesn't want to cooperate with me, as it insists that "@approval" should be an int32.Any suggestions?

I built a very simple report which uses a query to define the options in the parameter€™s dropdown. I used that same dataset to define the default for that parameter (meaning that it will just pick the first row from the dataset and use that as the default). When I run the report watching a Profiler trace on the SQL database, it runs that query twice. (Presumably, that€™s once to fill the dropdown list and once to figure out the default.) That seems silly to me since it is the same query that is the same dataset in Reporting Services. Is there any way around this? My parameter bar is rendering twice as slowly as it should be.
I've tested against SSRS 2005 SP1 and the CTP of SP2.
HI Experts,
I have same table structures in two database and one master table which contains Table id, Table name,primary key, data type of primary key. i have to comapare
Tables in both tha database and as per result i have to do insert,update or delete.
for that i have written query :
DECLARE @rowcount_mastertable FLOAT
SET @rowcount_mastertable = (select count(*) from master_table)
DECLARE @TABLE_ID float,
@TABLE_NAME varchar (100),
@primary_key varchar (100),
@Primarykey_DATATYPE varchar (50),
DECLARE @COUNTER FLOAT
SET @COUNTER = 1
WHILE (@Counter <= @rowcount_mastertable)
Begin
SET @TABLE_NAME = (SELECT TABLE_NAME FROM MASTER_TABLE TABLE_ID = @COUNTER)
SET @primary_key = (SELECT primary_key FROM MASTER_TABLE WHERE TABLE_ID = @COUNTER)
SET @Primarykey_DATATYPE = (SELECT Primarykey_DATATYPE FROM MASTER_TABL WHERE TABLE_ID = @COUNTER)
--In below line i want to declare a variable and datatype should be same as what we got from master table so that i can use this @MAX_primary_key to fetch --max of primary key from table name where table id is 1
DECLARE @MAX_primary_key @Primarykey_DATATYPE
SELECT @MAX_primary_key = MAX(@primary_key) FROM @TABLE_NAME
WHERE TABLE_ID = @COUNTER
---But by running it i am getting error that "Incorrect syntax near '@Primarykey_DATATYPE'. and "Must declare the variable '@MAX_primary_key'.
Please suggest

I am pretty new to SQL Server 2005 and SSIS. I am trying to dynamically load files into SQL Server 2005 using files/paths contained in tables. I have a key table in my SSIS package that defines which files should be processed, some default values that will be associated with each file (ie CompanyKey and PeriodKey) and the file path (see below for example):
CompanyKey
PeriodKey
ProcessFlag
FileName

The package I am developing is supposed to loop through this table checking for files with ProcessFlag = TRUE. For those files, it will load all of the records/columns (prefaced with the company and period keys) into a common table.
Do I have to manually create data sources for each file or is there a way to dynamically define the connection and process the connection?
Any assitance you could provide would be greatly appreciated!
Thanks.

Hi!
I'm assisting in the creation of a development enviroment with SQL Server 2005, and I need to assign some custom roles, in particular, a Stored Developer Role should be able to create, modify and execute Stored Procedures but they should not be able to alter tables or views, but should be able to retrieve/insert data from those tables.
I've tried with the default roles in 2005 to no avail.
Is there a relatively easy way to accomplish this with a database alredy populated with objects of both kinds? (SP's and Tables / Views)
Thanks!
Can someone verify that an assembly containing an interface with an event definition, such as...
public interface A {
event EventHandler Foo;
}
... can never be loaded under SAFE or EXTERNAL_ACCESS ?
It appears that the compiler-generated add_xxx and remove_xxx have the MethodImpl(MethodImplOptions.Synchronized) attribute defined by default, and "Explicit synchronization is not allowed". The same limitation also applies to classes by default, although technically one is able to define the implementation directly (clearly not ideal).

I have created a menu report listing available reports and am setting the Jump to settings of each text box in the list to take the user to the relevent report. But I am having a problem setting up drill down to reports with multivalued parameters.
What I want to happen when the user drills down is for the report to open up with no parameter values selected. This works for single value parameters where I have set Null as the default value. But I have not been able to figure out how to do this with MVPs. Does anybody know if this is possible?
As a workaround I have been using Jump to URL (rather than Jump to report), which has no problem opening the report without having to pass any values for the MPV. But I do not like using this as I use different DEV/UAT and PROD environments so would have to amend the URL for each environment.
Seems like this should be possible... Any idea?
Cheers, Mike
PS: I should add I can Jump to reports with MVP without specifying a parameter in development studio but not when the report is published.
Ok, so I open up a book on beginning sql and it discusses relationships.There is something that appears wrong. I am not understanding how the book is describing the one to one relationship. In it's figure, it shows that the same agency can have two different artist id's. But according to it's definition of one to one list can be related from both tables.Can someone explain this further please?Thanks in advance.
View 3 Replies View RelatedHow do you show many to many relationships in ASP.NET with datasources?
I can retrieve the information from the database easily but I can't manage to save that information into a variable so that i can then call for only information in the M2M table related to the ID Key I want. For example..1 <asp:Label ID="lblTestLabel" Text='<%# DataBinder.Eval(Container.DataItem, "title_id") %>' Runat="server" />

3 <script language="VB" runat="server">
4 sub Page_Load(sender as Object, e as EventArgs)
5 Dim lblTitleID As Label = Repeater1.FindControl("lblTestLabel")
6 Response.Write(lblTitleID.text)
7 End Sub
8 </script>
When I try to run this script it dosn't work and I get the error:
System.NullReferenceException: Object reference not set to an instance of an object.
For line 6 of the code above. Is there a way to just retrieve information from a datasource without storing information into a label first?
PS: I use sqldatasource tags to retrieve information like:1 <asp:SqlDataSource ID="DataSet1" runat="server"
2 ConnectionString="Driver={MySQL ODBC 3.51 Driver};server=localhost;database=;user=;pwd=;option=3;"
3 ProviderName="System.Data.Odbc"

We have a table with approximately 150 colums and 2/3 of them are bit datatypes. We do not expect much activity on this table. Does it make sense to separate it into a few tables instead of 1 with one-to-one relationships? Will the join(s) significantly slow down our web application? Thank you
