Hi
Could anyone tell me how can I set auto increment to a field in MSSQL at design time? So that whenever I insert a new record from VB, it will insert that new record incrementing the field which is not a primary key automatically.
Thank you very much for everyone who are constantly helping me...
Im trying to design my time dimension and need to add a field tohandle null dates in the fact. So if at the time of ETL the date isntknown, referential integrity will be preserved. Kimball suggestsinsterting a record in the time dimension to handle this with adescription of 'Date not available' or something like that. Howeverif users are doing inner joins on the dimension they will obvisouslybe pulling the datetime field..what should be in the datetime fieldfor this particular record?
View 4 Replies View RelatedMy SSIS package has 19 XML Source inputs constructed of 4 different (XSD) Schemas. I'm trying to find a convenient way to refresh the underlying metadata at design time so that I don't have to open each XML Source, change the XSD reference, click on the columns display, change the XSD back to the original but updated XSD just to get say a new default column width for string data. Does anyone have a quicker way to force an SSIS package to pick up changes in a referenced XSD?

Is there a way to determine that "I'm in runtime" vs "I'm in design time"?
Dear all,
i have a question concerning the design time support when accessing different oracle database schemas with SSIS.
I'm using an OLEDB-Connection, and in general everything is working fine. I would like to access two different schemas. One for production and one testing. So i have stored my connection properties in a configuration file, which looks different for prod and test.
I'm not allowed to connect to the oracle db with the user in who's schema the tables are located.
(e.g. schema=prod, my user=readonly)
Normally i must type SQL like: "select * from prod.MyTable" for my production datasource and "select * from test.MyTable" for my test datasource.
In order to clean up my sql i use the oracle "alter session" command. (alter session set current_schema=prod) The command is stored with the connection properties within my configuration file.
All of my packages start with this sql statement for the oracle datasource. (The connection property RetainSameConnection is true and the package property DelayValidation is set.)
So the solution is working fine.
But during the development i have a problem. When crating a datasource i can't retrieve the metadata infromation or build sql with the provided tools, because of "Table of View not found" (ok, the alter session statement is missing)
So does anyone know how to define a alter session for the design time conneciton?
Maybe something with the "Extended Properties" of the connection?
Thanks for your help!

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
Hi all,
I have run into a problem! Im developing a SSIS package programmatically using C#. But when i create and add a container (foreachloop and sequence) the container is not becommming visible in design time in my intergration services designer (when i open the .dtsx package afterwards). Does anyone have a solution to this problem? It is only a problem with containers i create myself (it is working when im adding e.g. dataflow tasks to existing containers).

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:
-------
Fixture
-------
fix_id
fix_date
fix_played
----
Team
----
tem_id
tem_name
-----------
TeamFixture
-----------
fix_id
tem_id
homeorawayteam
goals
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!

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 -

Hi, all experts,
Is there a way in SSIS dev environment that will let you convert/cast data type at desing time?
Under data flow mappings, there are so many things you can do, but why I did not find any easy way to convert?
I got this validation warning about not supportng converting type DT_STR to DT_I4, or something like that on many occassions..
I am using OLEDB Source as source and SQL Server Destination as destination.
Am I missing something obvious?
Thanks!
I've seen a couple of posts in this forum on this subject. If anyone knows of a workaround it would be great to hear.
The problem is this. I'm writing a component that looks a bit like an OLE DB destination: it writes to something that looks like a table. During design time I want the component to update the list of available destination columns if they change - so I want Validate to return VS_NEEDSNEWMETADATA if it detects a change. However during runtime I only want to validate that the component will run ok. So I still want to check what the destination looks like but if, say, someone has just added a column then my determination is it is ok to procede with the execution.
ValidateExternalMetadata doesn't help in this case because I still want to validate against the destination. I just don't want to raise VS_NEEDSNEWMETADATA during runtime because it aborts execution and I can determine that although there is a change to the destination it is not one that will cause the component to fail.
Any thoughts and experience on this would be great to hear!

When I'm designing a merge join in BIDs, in particular a large one with say a couple hundred columns on the left part of the join (and only 1-2 columns on the right side), it takes 2-3 minutes to close and I notice it pegs the CPU on the computer during that time. I'm developing on a quad dual core 64 bit machine with 32 Gb of RAM.
What makes this problematic is if you have a several merge joins in the pipe, and you do something like add a column. Then you have to re-open every merge join to include that column, waiting 2-3 minutes for it to close. So adding a column to a pipe with 10 merger joins will take 20-30 minutes, most of which is just waiting for edit boxes to close. I've tried the options of "work offline" and setting the ValidateExternalData to false in the merge join property but those don't help. Anyone encounter this problem?
Thanks,

How to design at database level such a way so that when I implement a SQL query that returns one hundred thousand rows only display 25 rows at the client (Web page at a time). How can I accomplish this?
Once I display first 25 rows then how do I bring next 25 rows and so on. Can it be done via paging or there are other techniques. However I asked to design this in the database level. I am using MS SQL Server 2008. Front end Visual Studio 2010. I use C# for coding.
BEGIN TRAN;
INSERT INTO [dbo].[QuestManualProcess]
([ProcessFromDate]
,[LastProcessedFileDateStamp]
,[ProcessedOnDate]
[code]....
Conversion failed when converting date and/or time from character string/

View 3 Replies View Relatedwe have problems with our SQL Reporting Service 2012 (SSRS) server . We have setup Kerberos delegation between SSRS and the database server (SQL Server Always-on cluster) so users are authenticated down to the database. The issue occurs from time to time that SSRS loses the ability to delegate the user credentials to the database. At this point in time the Report Server logs contain rejected database connections because of ANONYMOUS logon. After restarting SSRS the problem is gone.

View 3 Replies View RelatedI 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

View 2 Replies View RelatedWorking on a new database where the Date and Time are stored in a Date Time Field.
Then working on an OLDER database file within the same SQL Database contains these 2 items as integers:
transDate = "71615" (July 16, 2015)
transTime = "12345" (01:23:45 AM)
How do we convert both of them into a single SQL DateTime field such as "2015-07-16 01:23:45.000" so that it can be used in a join restricting to a date time in a different SQL File that properly has the DateTime in it?
This works well for converting the transDate Part in the select statement:
dbo.IntegerToDate(at.transDate) as transDate
* That returns: "2015-07-16 00:00:00.000"
* The resulting data must work directly in a Microsoft SQL Server Management Studio Query using either using the "on" statement or part of the "where" clause. In other words, NOT as a stored procedure!
Also must be able to be used as a date difference calculation when comparing the 2 files Within say + or - 5 seconds.
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.
Hello:
My client has a db with the following structure:
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.
thx

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
