LookUp Entities And Roles Against Multiple Entities?
Sep 10, 2007
Apologies if this has already been asked and answered, though I haven't found it via search.
In my report model I have a lookup entity that consists of a Code field (PK) and a Description field this is linked to a parent entity (table) and works fine, e.g. the description is shown in the parent entity instead of the FK code. However this lookup entity would be useful linked to many other entities (tables) which use the same FK code linked to the lookup entity's Code field (PK) for use of the Description field. In my first attempt I linked the lookup to a second table entity but unlike the originally linked table entity, this is not shown as the description in report builder, only the role appears and I have to select the role then the description from the 2 fields displayed (Code, Description), additionally I get shown the related first table entity.
Firstly can a lookup entity be linked to multiple tables?
Secondly, if so am I forgetting something so only the description is shown like in the first linked table entity?
Thirdly, if I correct the problem is there a property I need to enable/disable to stop the first linked table entity appearing in the second table entity entity list in report builder or should I just leave it?
Any help/advice/suggestions would be appreciated, and apologies for long list of questions but all the books and help files I have used don't seem to use imperfect/real life data sources and examples.
Thanks

Dear GroupCan anyone provide a sample query for the following scenario?Let's assume I want to search for an order someone placed which mightbe an individual or company. An individuals first name is stored incolumn FirstName And the individuls last name in column LastName of thecontact table and the company name is stored in column CompanyName ofthe company table.If a user issues a query with CName parameter how can I search allthese columns and tables at the same time to see if there's a match? Imight add that there's a column in the orders table that holds0=Contact 1=Company but ideally I don't want to use this column.Thanks very much for your help and efforts.Martin

Hi,
I’ve three questions, would someone answer them please,
I have 3 entities:
The book entity(BookNo,BookNmae,AuthorName,Price...etc), the MembershipCard entity(CardNo,MembershipNo,ClientNo,PublishDate,EmpNo..etc), and the Client entity(ClientNo,ClientName,ClientAddr,ClientPhoneBookNo,RequiredBookNo,..etc)
1-What is the relationship degree between them, is it ternary or binary?and Why?
I'm so confused ,my answer is ternary, I made a (1:m) relationship between the clients entity and the books entity (a client may buy more than one book), (1:m) relationship between the employee entity and the books entity (an employee may sell more than one book)and a (1:m) relationship between the employee and the Client(an employee may serve more than one client(is it right or it's (M:N)).
So is my answer is right or wrong, please help me to understand, I’m so confused.
2- Is the cardinality degree between the Client entity and the book entity , (0,N) for the client entity and (1:N) for the book entity??
3-What is the best model to use in designing data in general,Chen's model or Crow's Foot and why?I think it's Crow's one ,for it's more arranged and easy to read.
with thanks

I created a report model with a single "data source view." The datasource view has three tables "Business, XRef, Employee" and a named query "PeopleCount" based on these tables. The smdl [design] view shows "Business, XRef,Employee" as "entities" and does not show the named query from the "data source view" (I don't know if that is normal). I published this report model to the reporting server (its showed "success").
I then used Report Builder to open the report model as a "chart", and it shows there is only one entity for me to play with, its called "XRef." Why do the other tables ("Business" and "Employee") not show up in the Report Builder's list of entities?
My own guess is that "XRef" is the only "actionable" table for making a chart. Indeed, I notice that among its "fields" is one called "Business Title" (which apparently comes from the Business table). But I also notice it does not have an "Employee Name." Why have the former and not the latter? Again, my own guess is that the type of the Employee.Name field, a nvarchar(MAX), might be considered unusable for reporting, since it is a "max" size. Thoughts?
I am using SQL Server 2005 RTM, which is running on Win 2K3 Server SP1.

Why is it that only SOME of the tables in my database show up in the Entities pane?
There are a total of six tables in my database, yet only three of them are available to me in the Entities pane. I have looked at permissions, etc, and I am using the SA account. It seems like I should see either ALL or NONE of the tables, but that is not the case.
What am I missing?

Hi,
A Composite entity can be made out of two Primary Keys (PK) of two different entities. Therefore it can be called as a link table. Therefore the composite entity depends upon the other two entites. Therefore the composite entity is a exsitence dependent on the other two entities.
Therefore do every composite is a weak entity?

Hi Everyone,
I'm attempting to design a schema for a project I working on. The idea is that I can store a list of documents and associate meta data with them.
The problem is that I don't know what that meta data will be at design time. The user will create the meta data fields in the software. For the first design I just had a table called meta field that contained the meta field defintion, and another table called itemdata that contained the document primary key, the metafield primary key and a value encoded as a varchar. This works fine while the list of documents is small.
Another idea I've thought of is to have seperate tables for all of the metafields. This would allow me to be very specific about the values that can be stored in that column etc. It also turns out that for the kind of queries I'm doing its about 4 times as fast. The only problem is that the software will need to create these tables at run time.
What I would like to know is, is this a really bad idea? If so why?. Also are there any other ways I can store this kind of data?
The kind of queries I am doing are find all the documents where metafield 1 is A and metafield 2 is B and metafield 3 is C and metafield 4 is D etc.
Cheers,
Mark

Our customer (of our ecommerce system) wants to be able to preservedeleted entities in the database so that they can do reporting,auditing etc.The system is quite complex where each end user can belong to multipleinstitutional affiliations (which can purchase on behalf of the user).The end user also has a rich trail of past transactions affiliationsetc. Thus in the schema each user entity is related to many otherswhich in turn relate to yet others and so on.In the past when a user was deleted all of his complex relationshipswere also deleted in a cascading fashion. But now the customer wantsus to add a "deleted" flag to each user so that a user is never_really_ deleted but instead his "deleted" flag is set to true. Thesystem subsequently behaves as if the user did not exist but thecustomer can still do reports on deleted users.I pointed out that it is not as simple as that because the user entityis related to many, many others so we would have to add this "deleted"flag to every relationship and every other entity and thus have"deleted" past purchases, "deleted" affiliations - a whole shadowschema full of such ghost entities. This would overtime degradeperformance since now each query in the system has to add a clause:"where deleted = 0".I assume this is a standard problem since many organizations must havethis need of preserving deleted records (for legal or other reasons).I tried to talk them into creating a simple audit file where all thedeletions will be recorded in XML but they were not too happy withthat.Is there a more satisfying solution to this than have this "deleted"flag?Thanks for your help,- robert

I have the following data stored in a column in a table:
£10,000.00 & ' " % < > Guðmundsdóttir Björk Lårs Marqués María-Jose Carreño Quiñones
I query this in a stored procedure using the FOR XML clause and universal table, and store the result in an XML data type variable:
DECLARE@ResultXML
EXECUTE[someStoredProcedure] @Result OUTPUT
This data (as XML) is then written to a file; in order to do this, I CONVERT the data to NVARCHAR since there are unicode characters in the source:
DECLARE@strResultNVARCHAR(MAX)
SET@strResult= CONVERT( NVARCHAR( MAX ), @Result, 1 )
Now this works fine, except on inspection, SQLServer has decided to render the data thus:
£10,000.00 & ' " % < > Guðmundsdóttir Björk Lårs Marqués María-Jose Carreño Quiñones
Why it has changed the apos and quot entities to the corresponding character but not the other entities is beyond me.
how to preserve XML entities?

I have a database that tracks players for children's sports clubs. I haveincluded representative DDL for this database at the end of this post.A single instance of this database supports multiple clubs. I would like toadd support for letting each club define and store custom information aboutarbitrary entities. Basically, allows the clubs to define custom entities(i.e tables) and associated custom attributes (i.e. fields) that may berelated to existing tables (such as Player and FootballClub) or existingentities. For instance, a club may define a PlayerAssessment entity thatrecords all player assessments.To do this, I plan to support the following use case:1. FootballClub admin creates a new entity and gives it a name anddescription (Entity is only accessible to this FootballClub).2. FootballClub admin indicates that the new entity has a M:1 relationshipwith the Player table (this will add Player_ID as a FK attribute).- {An entity may have no relationships.}- {Relationships are also supported to other entities.}3. FootballClub admin specifies the names and domain/types of any dataattributes (i.e. fields) of the entity.- {An attribute's type may be constrained to a few allowable types likeRelationship, Integer, Float, Currency, Date, Time, DateTime, Name,Description and Memo.}4. System creates entity as specified.A few constraints:1. Any entity defined is "private" to the defining club. Other clubs aren'taware of it although they may define custom entities of their ownwith the same name and attributes. [Perhaps there is a way to sharedefinitions of identical entities?]2. A club doesn't have to define any custom entities.Ideas I've considered:1. Generate DLL and create actual tables- Restrict such customizations such that while admin is setting up entities,no other user is allowed to use the system.- Once entity definition is complete, generate an actual table using DLL.Table and column names might be changed to enforce uniqueness/validityconstraints - this suggests a need for table/column name mapping.- PROS: Easy to implement.- CONS: Doesn't scale since only a limited number of tables can be created.DDL on a live, shared system?. Scary!!All users for all clubs will be locked out while entity iscreated.2. Generate DDL and create actual tables in secondary database(s)- Same as above except that the user tables are created in secondary [,shared] databases.- PROS: Reassurance that DDL is never run on the "core" dataAll users don't have to be locked out.- CONS: Doesn't scale since only a limited number of tables can be created.{ Unless I start creating additional databases too!. }Still needs to DDL on a live, shared system.Has anyone done anything similar?. Any ideas on how it might be done?. Inparticular, is this possible without having to execute DDL on the livedatabase?Kunle=================== BEGIN DDL ===================CREATE TABLE FootballClub (Club_ID int IDENTITY,Name char(80) NOT NULL,Area char(4) NOT NULL,League char(4) NOT NULL,City char(30) NOT NULL,PRIMARY KEY (Club_ID))goexec sp_primarykey FootballClub,Club_IDgoCREATE TABLE Player (Player_ID int IDENTITY,First_Name char(30) NOT NULL,Initials char(30) NULL,Last_Name char(30) NOT NULL,Date_Of_Birth datetime NOT NULL,Position char(4) NULL,Club_ID int NULL,PRIMARY KEY (Player_ID),FOREIGN KEY (Club_ID)REFERENCES FootballClub)goexec sp_primarykey Player,Player_IDgoCREATE TABLE UserAccount (User_ID int IDENTITY,Club_ID int NOT NULL,FullName char(80) NOT NULL,Logon char(20) NOT NULL,PWD_Hash char(60) NOT NULL,PRIMARY KEY (User_ID, Club_ID),FOREIGN KEY (Club_ID)REFERENCES FootballClub)goexec sp_primarykey UserAccount,User_ID,Club_IDgoexec sp_foreignkey Player, FootballClub,Club_IDgoexec sp_foreignkey UserAccount, FootballClub,Club_IDgo=================== END DDL ===================

I have scoured the internet looking for someone who has run into this issue with no such luck!
Product: Reporting Services 2005 Analysis Services 2005
Our users use Report Builder as an ad-hoc report tool. Data sources for Report Builder come from Report Servers and Analysis Servers.
I have run into issues where a user will select a source for their report that is based on an AS cube. When they select an attribute (field) from a selected entity in the Report Builder Explorer and drop it on the canvas, all entities except the one the field was selected from disappear.
For example:
A cube has a fact table called "Annual Income" with dimension of employee and demographics. In Report Builder, the entities would be listed in the left hand Report Builder Explorer window as
Annual Income
Employee
Demographics
If I select attributes from Employee or Annual Income, as usual, you will see the related hierarchies of the remaining entities. However, if I select an attribute from Demographics, then the Annual Income and Employee entities just disappear and all I can see is the Demographics entity and its attributes.
Has anyone run into this and if so, any ideas? This is becoming extremely frustrating. I have deleted and rebuild cubes, individual dimensions, and everything else I can think of.
Your responses are appreciated,
Scott

Let's say I have an rdlc report for customers, and it has three sections with subreports:
CUSTOMER_INFO (name, phone, e-mail)
ITEMS
OBSERVATIONS
As the page only has 21cm and the report grows horizontally, I need to repeat the WHOLE report with all of its sections after every 4 customers. So if I have 5 customers, there would be three pages(let's say every subreport takes 1 page) for the first four customers, and then another three pages(with every section once again) just for one customer.
Is it possible? It doesn't seem somehing out of the ordinary, but I can't figure how to make it work. Everytime there is more than 4 customers, the report breaks its layout trying to accommodate the records in a new table below the tables of each subreport.
The expected result would be to bring all of exceeding data to new pages.

Hello:
I am still working on my project, but figured I would share my findings with the community, on how I imported my SQL Server database tables into a new SQL Compact Edition database. Unfortunately, I haven't figured a workaround to the IDENTITY_INSERT issue, but other than that, I will proceed.
1) I downloaded and played with the tool presented in the article "Generate SQL Insert statements for your SQL Server 2000 Database" I made the following modifications . (my modification can be found here)
a) Disable scripting dependencies
b) Add a filter for objects to script
c) Prompt for each table from which to export data
2) From the scripts output by this tool, I had to (which I may integrate into the tool later... who knows)
a) Remove 'On Primary' statements after the create table statements.
b) Remove date defaults.
c) Most other SQL generated by the tool seemed to work.
3) Execute each 'Create Table' statement individually.
4) For the Data Import, I had to add semi-colons to the end of each Insert Line.
5) I Have found no workaround for the IDENTITY_INSERT issue. If anyone has a good idea, I would love to hear it. In my case, I was importing the DotNetNuke core store module tables populated with about 2500 products and 20+ categories consisting of a simple categories table and products table. I imported the categories table into a fresh MS Access database file, and then ran the update query against the attached products table in the original SQL Database, then regenerated the insert statements, and imported the data generating fresh product ID's. This database will only be read only, so it didn't matter about maintaining the Product ID's, just the relationship between the products and categories.
Separately, I found a great blog article on how to embed a SQL script as a resource for your application and run it on your applications first run, so my steps above would provide a quick foundation for generating that sql script.

Hello,
I am new user of SQL Server. I have some problems with these words. I want to make my database works in my specified permissions. I will specify permissions with schemas and these schema wants an owner. I want this owner should be my user. When creating a user it needs a valid login. I am selecting my login and it occurs and error says this login has an different user. I am specifying permissions with roles. But i can't make association all of them. I hope i told my problem to you as well. If you explain these words to me and tell me how can i do my database's works with my own schemas, users and roles i'll be grateful. Thanks for advices.
Happy coding...

I have a TechFactTable containing the following information --- TechName1, TechName1 ... etc. There are 5 techs assigned to one record for round the clock service. For this fact table that I'm creating, I need to use a TechDimension (TechIDs, TechNames) to create a ID mapping that can be used in the fact table. The fact table needs to use the TechIDs not names.
I'm trying to create, can I set my lookup (ref table = TechDimension) to look up all 5 of these IDs at the same time?
For example,
Code Snippet
[TechFactTable]
TechName1 TechName2 ...
--------- ---------
Obama Clinton
[TechDim]
TechIDs TechNames
---------- -----------------
1 Obama
2 Clinton... ...
So i've set up my lookup query to return the TechDim info using something like
Code Snippet
SELECT T1.TechID AS TechID1,
T1.TechName AS TechName1,
T2.TechID AS TechID2,
T2.TechName AS TechName2
... (etc)
FROM TechDim T1 LEFT JOIN ON TechDim T2 ON T1.TechID = T2.TechID
After this I mapped my columns in the lookup so that I had
TechFactTable TechDim
TechName1 ------> TechName1
TechName2 ------> TechName2
and then return the newly added columns TechID1 and TechID2 but all in the SAME LOOKUP?

Is it possbile to have multiple fuzzy lookup within a data flow?
I need to have at least 3 fuzzy lookup in a data flow. Here're the conditions that I try to find match: 1=Zip&City, 2=Zip&State, 3=City&State. I've the first fuzzy lookup working fine. After that, I've a conditional split to get any unmatch, then use another fuzzy lookup for a second condition...at this point, I get the error saying "The package contains two objects with duplicate name of output column _Similarity..." I do not need to get the _Similarity and _Confidence, so is there a way to exclude them from returning in the output?
Any comments?

In a Lookup component I've defined a SQL query which returns a sorted resultset. For each Lookup component input row I want to have a single output row. Problem is that for each input row there is possibility of multiple matches in SQL query resultset. From all of the possible multiple hits I want only the first one to be returned, and if no match is found then no output row. How to implement this?

Please indulge my ignorance, as I have only been using SSIS for a couple of weeks.
I'm trying to create a data warehouse using two input tables.
A column needs to be added to one table by using a lookup into the second table.
SSIS seems to handle the "no matches" and "single match" cases perfectly.
I can't for the life of me figure out how to properly handle multiple matches.
SSIS defaults to the first match, but I need to compute the "best" match.
Many thanks in advance

Apologies if my post does not fit into this forum. I initially tried the SQL Server Data Access forum but I now think my question is more security related.
Is it possible for a web user who has been successfully authenticated with forms authentication to be authorised to use a SQL Server 2000 role depending on a particular ASP.NET 2.0 role that they have been authorised to use? I understand that that I can assign a SQL Server 2000 role to the ASPNET or NETWORK SERVICE account but this will grant access to anonymous web users to the database role. I can ensure that I only call stored procedures which access sensitive data in web pages that are in restricted by ASP.NET roles. However, it would be nice to also restrict stored procedures via the ASP.NET 2.0 Forms Authentication roles.
If this is not possible have you got any bright ideas how I could restrict access to stored procedures who are anonymous web users.
Many thanks,
Mark

I'm developing an ASP.NET2.0 application which accesses a SQL Server 2005 Express database. I plan to use integrated security for access to the database.
I'm confused about the relationships between Windows groups, the ASP.NET web.config file <allow roles=.../> and SQL Server roles.
I would like to create a Windows group to which I can assign multiple users and grant that group access to a Web Site using windows authentication and also grant that windows group access to the database my web application uses.
I have gotten the combination of Windows Authentication to the web site and to the database to work for a specific windows user but I am having trouble determining the combination of database security entities I must create to allow access to my database by members of the windows group.
For a Windows user:
1. Create Windows user
In SQL Express
2. CREATE LOGIN FROM WINDOWS WITH DEFAULT_DATABASE =
3. CREATE USER FOR LOGIN
4. CREATE ROLE
5. EXEC sp_addrolemember <role-name> <user-name>
For a Windows group, what would be the equivalent commands necessary to grant a windows group access to my database? Specifying the Windows Group name in sp_addrolemember does not appear to be sufficient even though the documentation states that a windows group name is a valid value for the member name argument.

After reading Books Online, I am still confused with Database Role vs Application role.
My intention is to control the end users' authority on the database, where the end users will access through Winforms client application. With proper assignment of schema and database roles to an user, I believe this will enough to control the permisison of an user.
If this is the case, why Application role exists? When and why should I use Application Role? How is it different from Fixed Database Role?

I can get this to work on a local desktop instance of SQL server, but not on my development server or production box. Any help is greatly appreciated.
Also I've stripped down the incoming data for the lookup to a very simplified version of what I'd like to use, but if I can't get it to work then I can't add addtional columns to match with.

I am in the process of locking down the SQL Server in an environment that is considered to be in production (pilot stages) and there is no staging or test environment that mirrors it. I need assistance in determining the server and database roles to assign to existing logins, most of which currently have sa and dbowner rights. Because it is not a development environment, I need to be sure that downgrading the server and/or database level permissions will not break any functionality.
I'm starting with the logins that have the SA fixed server role. These logins need to be able to install applications that require the use of a backend database, which will be stored on SQL Server. In addition, through the installation process a new login/password for the newly created database(s) is normally created. For the existing logins with the SA fixed server role, will downgrading to the securityadmin and dbcreator roles be sufficient to facilitate those needs, or are those too much/ too little? And should any user account ever be granted the SA role? If so, what questions could I ask to determine this need?
Since these install process for these applications usually prompt to install using SA or local system account to authenticate to SQL to create the new database(s), that account should have securityadmin and dbcreator roles to create the database and its tables, as well as add a new login to that database.
Please address this question, keeping in mind that the logins will only be performing the described actions, installing apps using SQL Server as the backend database and adding a login to that database (which may or may not be done during the installation process).
Thank you,

I work in the healthcare area, and am handling the survey data ETL's. There are around 8 different survey areas and based on information received from them for the visit they reference, I want to pull in more info from our invoicing database. My idea is this:
1.) Pull in the flat file to an ODBC staging table
2.) Cache all invoice records that fall between the MIN(Date of Service) and MAX(Date of Service) from the staging table.
3.) First lookup the information needed on patientID, providerID, date of service, and billing location.
4.) For the surveys that didn't match on those 4 columns, try looking up based on patientID, date of service, and billing location (since I could be 99% sure this would still return the record I need).
5.) For the remaining surveys, lookup based just on patientID and date of service. These records will be flagged for manual review because clearly, if a patient has multiple appointments in the same day, this will be prone to error.
However, in trying to use only 3 of the columns in the lookup, I get the error saying basically that I need to utilize all 4. Is there a way around this, or is there an entirely different way I should be approaching this? The reason I thought cache transform was the answer is because I will need to run a different package for each lookup, as the data and logic between each survey will vary, but the invoice data "pool" will stay the same regardless.

My report has two data sets that hold inventory from two different departments.
ds_DeptA and ds_DeptB
I have a table, that pulls the DeptB status of DeptA record and displays it. This returns empty when the lookup fails to make a match, which is fine. Typically means DeptB does not have the record yet. I need to count these empty (null) feilds and populate it in a Text box outside of the table.
I just can't figure out the syntax with multiple datasets. I can't use the lookup expression as part of the count expression since the count expression is not contained in a table that has a dataset.
table: ds_DeptA
fields:
ID
Name
date_set_to_DeptB
<<Expr>> =Lookup(Fields!ID.Value,Fields!DeptA_ID.Value,Fields!DeptB_Status.Value, "ds_DeptB")

(Error! hr=80040e21, hrDesc=Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work
Here is the code to connect to database which i am using.
CDataSource db;
CDBPropSet dbinit(DBPROPSET_DBINIT);
dbinit.AddProperty(DBPROP_AUTH_INTEGRATED, OLESTR("SSPI"));
dbinit.AddProperty(DBPROP_INIT_CATALOG, (const char *)bDatabase);
dbinit.AddProperty(DBPROP_INIT_DATASOURCE, (const char *)bServer);
dbinit.AddProperty(DBPROP_INIT_LCID, (long)1033);
dbinit.AddProperty(DBPROP_INIT_PROMPT, (short)4);
dbinit.AddProperty(DBPROP_INIT_TIMEOUT, (short)150);
hr = db.Open(_T("SQLOLEDB.1"), &dbinit);
if (FatalError(hr, "db.Open", buf))
{
*iErrorCode = hr;
return S_OK;
}
Any help, appreciated.
