hi
i'm trying to connect to the server without giving the static connection string.
i want my application to access the connection string automatically. i'm using the follwoing code, but it doesn't give the connection string
ConnectionString = @"";
conn = new OleDbConnection(ConnectionString);
cmd = conn.CreateCommand();
can u please explain that what am i missing, as i've already used the same code once and it is still working, but now that i am using the same code at some other location in the application it is not working.
thanku for the time

ConnectionString = ConfigurationManager.ConnectionStrings("YourConnectionString")

Use a LEFT JOIN on the Book table.

Hi:
We are combining alot of old applications which each have their own tables and structures within those tables...not really compatible enough to combine straight out...but they could all use the "text" or similar sql server type and be put into one or two "super" tables with a type to differentiate them.
On one side, this would vastly simplify our schema and allow the data to be centralized. On the other, its not intuitive and could be confusing if we fall behind with our database schema documentation. But more importantly, having all of these applications hitting these one or two tables puts a fair amount of stress on our server.
This table might look something like this:
Application 1 is type 1
Application 2 is type 2
Application n is type n
Text1--Text2--Text3...--Textn--Type
val1 val2 val3 valn 1
val1 val2 val3 valn 2
val1 val2 val3 valn n
Any thoughts of this issue would be appreciated.
Thanks!

A database should contain data that is related, assuming you are talking about a RDBMS. If the data is not related then putting it all together in a few master tables will be confusing years from now, or even tomorrow if there is enough of it.
You could use master DBs for things like zip code and other common fields but to try to mash everything together would be a big mistake IMHO.

Hi cleako:
This is a very valid point...and it will grow.
Thanks!

Ok, scrapping this idea and leaving original tables intact...this just ignor every accepted database design practice I have learned...chalk it up to a bad idea 
|
|

|

Was this a boss' idea or yours?

whenever we connect to sql server it return timeout exception ErrNumber = -2
Query result return in query analyzer it takes 44 seconds and in ADO it returns Connection timeout
what we do?
First we create a datatset and then
create object of dataadaptor and call Fill method after 50 to 60 seconds it returns connection timeout
|
|
|
|

44 seconds is a fairly long time for even Query Analyzer. You can extend the DB connection time in the connection string, I think it defaults to 30 seconds.

You are quite correct. The CommandTimeout defaults to 30 seconds.

I'm not exactly sure what you are asking.
Are you asking for help with the data model such that you can store this information in the database?
Do you have a data model, but are unsure of how to query it?
Do you need help calling the query from your application?
Can you provide more information, please. It will help us answer your query accurately.

my application consist of multiple forms and i want to make the first form as log in form , all i want is to let the users assign their log in names and passwords and save these log in details on the log in table , as any application does ..

give me triggers advantages...
|
|
|

you can use them to stop unwanted inserts, or deletes, updates
you can use INSERTED, DELETED tables in triggers in SQL server to see new data
They are nice to preserve referentially integrity.
Other than that I cant think of a really cool use of triggers.
I guess one could also use them for additional security if some bad user got a valid connection string and attempted to hack you Dbase.
You could use a trigger say to test for logged in, and only then permit the users action

hi every one,
well a few days ago I posted a questio abt the problem in transactional replication . well now I've been able to setup the replication among the Databases (SQL Sevrer 2000) but still there are a few problems remaining to be solved:
1. while I was making the pull subscription there were a lot of errors on many tables like "cannot copy bulk to tablexyz", "Alter table statement failed due to foreign key constraint", "Cannot drop table.." etc but now there is only one error left on a products table that has a self join. it says some thin like "Alter statement failed due to foreign key same name contstraint " or somethin liek that. and I tried all the options in the snapshot tab of the article but every time there is some error like bulk copy error or this or somethin else. So right now I am absolutely void of any further ideas and God it really is frustrating. Can u plzz give me some clue of whats goin on. What should I do here. is there any alternative?
2. the tables that have been replicated are not passing the updates from the subscriber to publisher althouhg I have the "propagate updates using MSDTC" option selected. There are no vertical or horizontal filters here. and the thing is that the schema was already existing and I havent given a new name for the destination table. While I was practicing I noticed that this thing happens when u usethe same name for the destination table. So how can this issue be solved bcz I really can't afford to change table names now.
thanks for ur time...
