hi all,
How do i avoid duplicate records on my database? i have 4 textboxes that collect user information and this information is saved in the database. when a user fills the textboxes and clicks the submit button, i want to check through the database if the exact records exist in the database before the data is saved. if the user is registered on the database, he wont be allowed to login. how can i acheive this?
i thought of using the comparevalidator but i'm not sure how to proceed.
thanks
Hi,
I've got a database called Webmine which is running with multi users.
I want to duplicate it to generate archive.
My problem is that I can't duplicate the MDF file (and the ldf file optionally) without detach the webmine db and reattach after the duplication.
Detach this database is a problem durring this processing of duplication because we can have users always working on Webmine.
Is there a way to proceed without detach Webmine ? Or perhaps it's stupid or dangerous to duplicate a DB if users are always working (that's my position but here, everybody does not agree with this position so can anybody certify
I've got or not reason ?
Thanks to your answers

Instead of me testing my scripts on my main commerce database I was wondering if there was an easy way to duplicate my most currnet database as another database...
that way if I screw up I can just delete it and try again
I looked at the restore as in enterpirse manager, but I don't think thats it
I have built a template database which I'm finally pleased with, however I want to periodically duplicate the design - not data into a new database. How can I duplicate a database? I was hoping to right mouse, copy, then right mouse, paste, and then be prompted for the new name but no such luck.

from the sample data you can see that there are multiple records is there a way of clensing the data using a sql command?
is there any issues such as performance on clensing it etc?
are there any strategies that should be implemented at the data tier so as to prevent duplication of data?
Hi folksI know just enough about MS-SQL to be dangerous, so feel free to warnme off this it's too much for a non-expert.We are using SQL 2000 as the back-end for website. We would like tocreate a duplicate of the database (on the same server). Then we'd usethem like this:Database A: read-write DB accessed by web administratorDatabase B: read-only 'live' DB accessed by the web serverThe smarts: setting up a way to maintain Database A, have it beaccessible internally (maybe different IP, maybe different port) andwhen a change is approved, have that change replicate to Database B tobe visible on the website.I'm wondering if it's something I can do myself with the rightreading, or I'm going to have to hire some SQL know-how to help meout.Dave
View 1 Replies View RelatedHello Everyone:
I am using the Import/Export wizard to import data from an ODBC data source. This can only be done from a query to specify the data to transfer.
When I try to create the tables, for the query, I am getting the following error:
Msg 2714, Level 16, State 4, Line 12
There is already an object named 'UserID' in the database.
Msg 1750, Level 16, State 0, Line 12
Could not create constraint. See previous errors.
I have duplicated this error with the following script:
USE [testing]
IF OBJECT_ID ('[testing].[dbo].[users1]', 'U') IS NOT NULL
DROP TABLE [testing].[dbo].[users1]
CREATE TABLE [testing].[dbo].[users1] (
[UserID] bigint NOT NULL,
[Name] nvarchar(25) NULL,
CONSTRAINT [UserID] PRIMARY KEY (UserID)
)
IF OBJECT_ID ('[testing].[dbo].[users2]', 'U') IS NOT NULL
DROP TABLE [testing].[dbo].[users2]
CREATE TABLE [testing].[dbo].[users2] (
[UserID] bigint NOT NULL,
[Name] nvarchar(25) NULL,
CONSTRAINT [UserID] PRIMARY KEY (UserID)
)
IF OBJECT_ID ('[testing].[dbo].[users3]', 'U') IS NOT NULL
DROP TABLE [testing].[dbo].[users3]
CREATE TABLE [testing].[dbo].[users3] (
[UserID] bigint NOT NULL,
[Name] nvarchar(25) NULL,
CONSTRAINT [UserID] PRIMARY KEY (UserID)
)
I have searched the "2714 duplicate error msg," but have found references to duplicate table names, rather than multiple field names or column name duplicate errors, within a database.
I think that the schema is only allowing a single UserID primary key.
How do I fix this?
TIA

Hi all.. I've been scouring the forums for about 6 hours to no
avail. This is a really simple question. I'm trying to have
a registration page that lets the user input name, email, desired
username, and password. I want to check the username and email
fields to make sure ppl cannot sign up twice. So from what I've
gathered I have a couple of options:
1) i can set up a unique constraint on the database columns,
2) i can run a select statement before inserting,
3) i can store the whole database column in a variable then search through it.
My question is how to do option 2? All of my transactions are through a sqldatasource object in c#.
Our programs have and would like to continue keep the same data in multiple database. Example phone numbers. Us DBAs are tring to convince them not to.
Other than keeping the data current, what avantages are there to keep data in one location for multiple application to access.
Hi all,
I want to transfer a database from one MS SQL Server 7.0 to another.
When I create a new database (SQL Server 7.0) and then try to load a backup, I always end up with a message that the backup database is not identical with the destination database. That is correct and I know it, so what!? Is there any other possibility to transfer a database other than Export/Import. Using this method took me about 48 hours for 6 GByte database!
All suggestions are welcome
Thank you

I've begun to get the above error from my package. The error message refers to two output columns.
Anyone know how this could happen from within the Visual Studio 2005 UI? I've seen the other posts on this subject, and they all seemed to be creating the packages in code.
Is there any way to see all of the columns in the data flow? Or is there any other way to find out which columns it's referring to?
Thanks!

How can I compare numerous rows in the same table that have the same fname, lname and access_id but different identity values (and other columns) and then keep only the one row which is the most current based on a date col?
This seems so easy, but today I just can't come up with it. Do I have to use a cursor of some kind?

Hi guys,
i have the following tables:
Table1:
[PKID] WITH INDEX "IGNORE DUPLICATE KEY"
Table2:
[FKID]
and i have the following SQL statement:
insert into Table1
select distinct FKID
from Table2
where FKID not in (select PKID from Table1)
The above SQL statement is in a DTS package which raises "Duplicate key ignored" error... i can't see how that can happen since i am already checking the key if it already exists. ..
Please help !!!

I'm currently working on a Game DB, To where i can set Primary Key's and such, otherwise the Emu reads it wrong. The current table i am working on, has duplicate row's of every row. (3600 rows instead of 1800) and the duplicates have the same ID as the original row. How would i go about Deleting the Duplicate rows without harming the original? (Sql 2005)

I have a stored procedure that inserts records into a table with a Unique Clustered Index with ignore_Dup_Key ON.
I can run the stored procedure fine, and get the message that duplicate keys were ignored, and I have the unique data that I want.
When I try to execute this in a DTS package, it stops the package execution because an error message was returned.
I have tried setting the fail on errors to OFF, but this has no effect.
I found the bug notification that says this was corrected with service pack 1, and have now updgraded all the way to service pack 4, and still get the issue.
I tried adding the select statement as described as a work-around in the bug, and still can't get it past the DTS.
I have verified the service pack, re-booted, etc.....
I am trying this in MSDE 2000a.
Thoughts or comments? Thanks!
