I need advice on my design.
I'm developing a system that track the catalog distribution.
I have a 5 table.
Company Table - Store list of company. Each company can have many staff.
Staff Table - Store list of staff.
Catalogs Table - Store list of catalog. Each catalog can have many revision.
PKEY id
name
latest
CatalogsRev Table - Store list of catalog revision.
PKEY catalogID -> Catalogs.id
PKEY year
Staff_Catalog Table - Each staff can have many catalog revision.
PKEY staffID -> Staff.id
PKEY catalogID -> CatalogsRev.catalogID
PKEY year -> CatalogsRev.year
Is the above table good enough to track which company do not have latest catalog revision?
For the Catalogs Table should I use a trigger to update the Catalogs.latest column everytime a new CatalogsRev is entered?
I've read some article on the web says trigger is slow, but in my situation is it suitable to use trigger?
We replicate a SQL2000 database (DataBaseA) to a SQL2000 database (DataBaseB) by using the Restore function and hasn't change its logical name but only the physical data path and file name. It is running fine for a year. We use the same way to migrate the DataBaseB to a new SQL2005 server with the Restore function and the daily operation is running perfect. However, when we do the Backup of DatabaseB in the SQL2005, it just prompt the error message
System.Data.SqlClient.SqlError: The backup of full-text catalog 'DataBaseA' is not permitted because it is not online. Check errorlog file for the reason that full-text catalog became offline and bring it online. Or BACKUP can be performed by using the FILEGROUP or FILE clauses to restrict the selection to include only online data. (Microsoft.SqlServer.Smo)
Please note we left the DataBaseA in the old SQL2000 server.
Please help on how we can delete the Full-text catalog from DatabaseB so we can do a backup
"SSIS 2012 Catalog doesn't have option to give read access to SSIS Catalog to view package run reports" ... Any luck allowing power developers / operators access to READ the SQL 2012 SSIS Execution Reports without granting them SSIS_Admin or Sysadmin?
According to this link posted back in 2011 (w/ Microsoft's feedback in Nov 2011: "We’re closing this issue as “Won’t Fix.” At this point the bug does not meet our bar for resolving prior to SQL Server 2012 RTM. As we approach the SQL Server 2012 release the bar for making code changes gets progressively higher." URL....Regarding Permissions to SSIS Catalog, here are the findings. We can give access in three ways:
1. READ Access – We can provide a user db_datareader access. With this the user can see the objects within the SSIS catalog database, but cannot see the reports.
2. SSIS_ADMIN – Add the user to this database role in SSISDB. With this the user can view the reports. But it also provides them privileges to modify catalog information which is not expected. We can add it using below script EXEC sp_addrolemember 'ssis_admin' , 'REDMONDPAIntelAnalyst'
3. SYSADMIN - Add the user to this server role. This will make the user an admin on the SQL server. This is not intended. Is there any method available which will have provision to give read only access to see SSIS Catalog package execution reports and not having modify Catalog access.
Frank writes "Any suggestion on the best design to store data for resource management so that data can be displayed afterwards in something like a gantt chart.
For example, you have to asign resources, say personID 1 to 100 to fill positions A, B, C, D, E and F
A position must always be filled. A person can only fill one position at a time. You want to be able to detect overlaps when you do your planning.
So if person 2 is in position B from 1 Jan to 15 March, he is currently unavailable, but he should be availabe in my planning for any position from 16 March onwards etc.
Possible queries - 1) list all positions not filled during period XXXX to YYYY 2) List all persons available to fill a certain postion during period XXXX to YYYY 3) List any overlaps where a person is assigned to different postions during overlapping time frames..."
I'm using SQL Server 2008 R2 Management Studio. I have a view that I'd like to index. Obviously, that requires that the view be schema bound to the underlying table. I have found myriad explanations for how to programmatically create a schema bound view, but I've never created a view like that before, and since I'm more a mechanical engineer than a database manager, I'd like to be able to do it the 'easy' way, by just creating the view in Management Studio by going to the database, right clicking on 'Views', clicking on 'New View...' and then, hopefully, checking some box somewhere that schema binds the table to the view.
I need to develop a strong licensing solution based on the database accessed... Currently our solution is easily hackable because the the license information is kept in the database of your choice and is not dependant on some static information, the current encryption key is static and kept in the software so it can be hacked easily. What i want to do to change this is simple in nature but i don't know how to get that one particular info i need. I want to get some kind of unique identifier for a database (catalog) that sql server could generate. This info must be static and must not be movable. If for example, someone would backup and restore, this information would not be transfered with the backup. Thus, a user that backups his database and restores it on another database server or another database catalog even on the same server would corrupt his license since the Unique ID returned by the SQL Server would be different; the hashing code would change and thus the decryption would fail. Is there any such info i can query using SQL that will not require admin rights?
I got the following error msg last night, in fact running anything in a query window. My solution was to stop and restart the SQLServer, but not ideal in a production environment. Anyone know what the cause/solution could be?
TIA, Neil
sg 910, Level 17, State 1 Could not allocate a new object descriptor for required system catalog in database '1'. Another database must be closed or objects in another database dropped in order to open this database. Msg 2812, Level 16, State 4 Stored procedure 'sp_who' not found.
While attempting to query a Full-Text enabled database where a catalog exists for the database, I receive the following error: "Full-text catalog %database% is in an unusable state. Drop and re-create this full-text catalog." I have dropped and re-created the full-text catalog numerous times with no luck. I have also stopped and restarted the SQL Server service and Full-Text service engines mulitple times with no luck. Other items to note are, we're running SQL 2005 64 bit Enterprise Edition SP1 on a Windows 2003 server. We have an identical setup in development and full-text indexing works without any hitches. I have also checked both the SQL server permissions and the local file-system permissions and they also seem to be more then adequate; in addition, they match the security configurations of our development environment. Lastly, the production database is a restore of the development database.
In short, I'm hoping that someone may have a potential solution other then reinstalling SQL Server...which may end up being the only solution.
Im trying to register my CLR UDF in SQL 2005 using this code CREATE FUNCTION GetSomething() RETURNS INT AS EXTERNAL NAME MyAssembly.MyFunction.MyMethod When I run it against my DB I get this error: Assembly MyAssembly was not found in the SQL catalog of database MyDB Ive successfully registered my custom assembly in the DB (I see it under Assemblies folder), and Ive set CRL Enabled to 1 in my DB. What am I doing wrong? Thanks in advance
Ok, I'm doing a football database for fixtures and stuff. The problem I am having is that in a fixture, there is both a home, and an away team. The tables as a result are something like this:
It's not exactly like that, but you get the point. The question is, can I do a fixture query which results in one record per fixture, showing both teams details. The first in a hometeam field and the second in an away team field.
Fixture contains the details about the fixture like date and fixture id and has it been played
Team contains team info like team id, name, associated graphic
TeamFixture is the table which links the fixture to it's home and away team.
TeamFixture exists to prevent a many to many type relationship.
Make sense? Sorry if this turns out to be really easy, just can't get my head around it at the mo!
In the v1.2 CTP version, the DatabaseMetadata methods for getting information about objects in a database (i.e. getTables(), getColumns(), ...) errors if your current database connection is in a different database than the object you are quering.
Is this the intended behavior going forward?
In my case I have access to both database A and database B. My current connection is in database A , but I am looking up object in database B.

After detaching the database I placed the database files and log files in the D folder as C drive was full. When i try to attach the files I am getting an error Failed to attach database Microsoft SQL Error 7622 (QCFTCAT Full text catalog).
I checked there is a folder in C drive by name QCFTCAT and the C drive has no space. What does this folder means please let me know on the same.

I actually work in an organisation and we have to find a solution about the data consistancy in the database. our partners use to send details to the organisation and inserted directly in the database, so we want to create a new database as a buffer database to insert informations from the partners then make an update to the main database. is there a better solution instead of that?
Hello everyone,I have a webcontrol that uses database-structures alot, it uses the system tables in SQL to read column information from tables. To ease the load of the SQL server I have a property that stores this information in a cache and everything works fine.I am doing some research to find if there are anyway to get information from the SQL server that the structure from a table has changed.I want to know if a column or table has changed any values, like datatype, name, properties, etc.Any suggestions out there ?!
I have a system that basically stores a database within a database (I'msure lots have you have done this before in some form or another).At the end of the day, I'm storing the actual data generically in acolumn of type nvarchar(4000), but I want to add support for unlimitedtext. I want to do this in a smart fashion. Right now I am leaningtowards putting 2 nullable Value fields:ValueLong ntext nullableValueShort nvarchar(4000) nullableand dynamically storing the info in one or the other depending on thesize. ASP.NET does this exact very thing in it's Session State model;look at the ASPStateTempSessions table. This table has both aSessionItemShort of type varbinary (7000) and a SessionItemLong of typeImage.My question is, is it better to user varbinary (7000) and Image? I'mthinking maybe I should go down this path, simply because ASP.NET does,but I don't really know why. Does anyone know what would be the benifitof using varbinary and Image datatypes? If it's just to allow saving ofbinary data, then I don't really need that right now (and I don't thinkASP.NET does either). Are there any other reasons?thanks,dave
Hi All,Can u please suggest me some books for relational database design ordatabase modelling(Knowledgeable yet simple) i.e. from which we couldlearn database relationships(one to many,many to oneetc.....),building ER diagrams,proper usage of ER diagrams in ourdatabase(Primary key foreign key relations),designing smallmodules,relating tables and everything that relates about databasedesign....Coz I think database design is the crucial part of databaseand we must know the design part very first before starting up withdatabases.....Thanks and very grateful to all of you....Vikas
I have installed 2 SQL Server 2005 Express sample databases from 2 books, ASPnet 2.0 and ADOnet 2.0. The ASPNETDB.MDF was shown in App_Data and Database Explorer, but not in the SQL Server Management Studio Express. The AdoStepBy Step database created by a ConfigDB.exe was displayed in the Management Studio, but not in the App_Data, or Database Explorer.
Is this the way SQL Server 2005 runs the 2005 databases for SQL Server 2005 Express only? Or also in SQL Server 2005?
In SSMS, I connect Object Explorer to a partially contained database using a contained user login with password. This user has a database role of dbdatareader. When I try to expand the Tables in the database, I get the error:
The SELECT permission was denied on the object 'extended_properties', database 'mssqlsystemresource', schema 'sys'. (Microsoft SQL Server, Error: 229)
Is there a way to set permissions for the contained user so that this could be done?
Hi All, I am designing database where few of the master tables will reside in different database or in case different server. Scenario is Server "A" with Database "A" may host the "Accounts" table. Server "B" with Database "B" may host the "Product" table. I am designing database "Project" which will hosted in Server "A". My application requires this master tables [readonly access] as data inserted in my application refers this tables. Also there are reports to be generated which refer this tables. How do i design my database and sql queries? I am thinking of approach of having equivalent tables created in my database and writing service which keep tables in my database in sync. This will ensure good perfomance during transaction and reports as they will need to refer this table locally as opposed to different database or different server.
Any thoughts on above approach?? or any better/standard way for such scenarios ?
Thanks in Advance. Your inputs will be of great help.
Online US Searchable Map of the 50 US States. Users search criteria is the following: Query records by selecting state, county, then record. Each County table has 10-20 tables. All databases combined = 500MB and TLogs = 100MB.
How would you re-design a relational DB where users could query data by state-county-record. Currenty the DB's are created by the County of each state which creates hundreds of DB's in SQLServer with no realtionship to each US state. What would be the best design to ensure good performance, data integrity and maintenance? Would you create 1 DB with all 50 states, create 4 DB's and divide by region(N,S,E,W), 50 DB's of each state or leave it as is with each county it's on DB? Any suggestions would be appreciated.
Hello, I am designing my first database with 5 tables for a demo project and am not sure if it works. an example below.2 of the many things I want visitors to the site to do is find a company by the industry sector they belong to,..andwhat sort of service or products they can supply. For instance a Employment agency maybe under professional services Table 1 Customer Customer_ID = primary key,,,, Sector_ID = Foreign keyComapany Name, Address, Phone, Postcode etcTabel 2 Industry SectorsSector_ID = primary key,,,,Customer_ID= foreign key banking, Education,Prof Services, etc Table 3 Trading ActivityTrading_ID = primary key,,,,Sector_ID = Foreign key, Products_ID= FkEmployment Agent, School, Lawyer etcTable 4 ProductsProducts_ID = primary key,,,,Trading_ID = foreign keySupply frozen foods, transport services, sports goods, etc Table 5 Account Account_ID = primary key,,,,Customer_ID = foreign keyAccount Name, Credit Limit, Payment Terms, Open date, Account contact etc One big point of confusion is, can I have the Customer_ID from the principal Customers tablein every table as a foreign key or must the tables be chained together one after the other as such. Advice appreciatedThanks
Hi, I need a hand with designing a database. I am collecting results from a survey which has the following questions: Call ref? How did you place your support call? Were you satisfied with the amount of time you had to wait until getting acknowledgement of the support call placed? 1 = very satisfied and 10 = very unsatisfied. How happy were you with the customer service you received upon placing the support call? 1 = very unhappy and 10 = very happy.How satisfied were you with the amount of time you had to wait until you heard from an engineer? 1 = very satisfied and 10 = very unsatisfied. How satisfied were you with the time taken to get your problem/query resolved? 1 = very satisfied and 10 = very unsatisfied Did you feel the engineer had enough knowledge to deal with your call? 1 = very good and 10 = not very good Overall how satisfied were you with the support call placed? 1 = very satisfied and 10 = very unsatisfiedIs there anything we can do to improve the quality of the support and service you received? I want to store this in a database. Obviously I want to use best practice for design, normalisation etc. The stumbling block I am coming accross is the fact that each question has a number and each question has a score from 1 to 10 and storing this in the database. Any help appreciated! Thanks Andrew
I am creating database tables for company testimonials. Database columns: name, position, companyname, comment, service we provided. My question is that for each company - may have a multitude of different services from us, and different people with different positions in the same company may make comments. What is best practice for putting this db structure together? Thanks Andrew
Can anyone tell me how can i design database architecture for the Table Category & Product...so that i can make N-level entity relation....I have database in SQL SERVER 2000.
I guess I am confused about something and need some help. I am looking at a database schema for about 20 tables in a database. I noticed that the firstcolumn in each table Is some type of Id. For example StudentId,TestId etc.Where the Id is a unique numeric sequential value. So I have some questions?1- Do these Id's act as what are called indexes for the table?(Unique indexes)2- If the answer to 1 is correct, then how do I create these unique indexes? Is it as simple as declaring the Id column as the primary key and that this value will be generated automatically upon insert? 3- Is it necessary to have an Id column for every table, or may I only do it for a few of them?4. In relation to Question2, what do I need to do, so that the Id column will automatically be created when someone inserts a value into the database table with an ID column. For example here are two sample tables StudentsInfo StudentId<PK> Name Age 1 Mark 33 2 Jill 23 3 Mary 25 PersonalInfo Name<FK> SocialSecurity Address MajorMark 324-444-3342 15 Elm ArtJill 888-888-8998 21 North ScienceMary 876-777-2344 18 Byle Music

Hi !!We are designing a system where we ask people for their interests and store in into the database and send customize email. Following are the questions:1) Should we use Identity column as Primary Key and CustomerID column? OR we should create Custom CustomerID and use it as Primary Key? (I have read few articles about Identity column as Primary or not Primary, but need little advice what to accept)2) We have a Tables called : Interest & Customer_InterestCustomer Table:CustomerID, Customer Name, Address, Email, Signup DateInterest Table:InterestID, InterestNameCustomer_Interest: (Need suggestion for How to design this)Should Table be design like:Option1: CustomerID, InterestIDOption2: CustomerID, Interest1, Interest2, Interest3, Interest4i.e.Lets Say: Customer table has CustomerA, CustomerB, CustomerCInterest table has Interest I1, I2, I3, I4Lets Say CustomerA Signedup for Interest I1, I2, I3 and CustomerB signed up I1, I4As per Option1:Customer_Interest Table witll haveCustomerA, I1CustomerA, I2CustomerA, I3CustomerB, I1CustomerB, I4ORAs per Option2Customer_Interest (Where Interest Column is bit column..... 1 = Signed up, 0 = Not Signed upCustomerA, 1, 1, 1, 0CustomerB, 1, 0, 0, 1Which way we should design? 3) If we select Option2, and if we are displaying data in ASP.NET Page, will there be any issue if we use 3 tier architecture?Thanks !!!
