Changes To Cloned Database Are Affecting The Original
Oct 20, 2006
I am trying to use SQL Express to support unit testing of functionality which requires database access.
I created an express database (.mdf) which contains a database snapshot which is the database environment that each test expects to see when it starts. Through the execution of the test the database will be modified arbitrarily and I need to reset the database to the original state before the next test executes.
Here's what I do today:
Before Test:
The original database is copied to a unique location in the temp directory
A unique database name is generated (GUID-based)
I connect to the new database file with:
When I do this, everything seems to work correctly but when I re-open the original database it has changed unexpectedly and includes the modifications that were made by the test as it ran.
Can anyone explain why this is happening and/or provide a solution?
Is there a way to copy the structure from one database to anotherwithout affecting the actual data?For example, I added new fields and stored procedures to a db in mydevelopment environment. There are a lot of them.I now want to make the same changes to my production environment db butdon't want to affect the data. Only the fields, stored procs &constraints and stuff pertaining to the structure of the db should bechanged.Does anyone know of a program that can do this or can this be done inMS SQL Enterprise Manager.Any help would be appreciated.7078895

I have an original database that I want to copy once to another database. Then I want to update the data weekly with the data of the original database. I don€™t change any tables or columns in that part of the database. Just some tables more in the €˜new€™ database (than the tables from the original database) with some references to the tables that have to be updated weekly. How can I do this? (if you know what I mean... it's a sort of a datawarehouse where different sources come together.. that part that represents the original database is just a part of the datawarehouse. That part is exactly the same structure as the original database.)
I need a little help with a cloned SQL 2005 install. We have a couple of Virtual Machines that SQL 2005 was installed on. The install was orginally completed on <pc1> and then duped over to <pc2>. The problem now is that <pc2> is showing information from <pc1> everywhere. I have reviewd this document: http://msdn2.microsoft.com/en-us/library/ms143799.aspx, and it doesn't seem to help any. I have used the sp_dropserver command with 'droplogins' to try to recreate the logins for <pc2> but it's still showing the logins from <pc1>. Can someone please help me out, I'm not sure what I'm doing wrong here. Thanks!
Hi,Good morning to All. While doing practice I did some modifications to some tables in Northwind database.Now, how can I get my original tables back again? Take Oracle for example:We can modify table data. But when we run demobld.sql script then all tables will replaces with original entries. Like this I want in SQL Server also. Is there any such facility available in SQL Server? Thanks in advance,Ashok kumar.
I made a copy of a database "sac_prod" and named the new copy "vgs_prod". Now, when I do a backup of the new database, it still shows the name of the original. Is there any way to change this so it will be the same as the new database name?Here is the BACKUP script:BACKUPdatabase vgs_prod TODISK='\sac-srvr1data$TechnicalSharedProductionSQLBackup LasVegasvgs_prod_CopyOnly.BAK' with COPY_ONLYHere is the messages I received from this BACKUP:Processed 1752 pages for database 'vgs_prod', file 'sac_prod' on file 1.Processed 6 pages for database 'vgs_prod', file 'sac_prod_log' on file 1.BACKUP DATABASE successfully processed 1758 pages in 0.412 seconds (34.955 MB/sec). I would like to change the file 'sac_prod' to be 'vgs_prod' in lines 1 and 2 just above. Thanks,
I am working on a project that contains several databases in SQL and many settings. The problem I am encountering is that I want to be able to update the program for all my customers. That is no problem.
The problem I am meeting is where, when the program is updated, all the settings and all the information in the databases reverts to the default values, or the values that were compiled with the new update.
I want to be able to update their program without deleting all the settings they have.
I cannot open now my database after changing it name from the folder where it is save and also changed back to its original name.Message recovery pending now is appearing as shown below.Any chance that I could recover my database back?
I have a table with 23 columns. 8 columns are not always filled by users and so valued to default. Would this affect the overall performance of querying this table? Should I separate those 8 columns and link with a one-to-one relation?
I have a table "PageInfo" wich has columns "PageID, Title(has "AboutUs" as one of the values), DateModified, Active". My other table is "AboutUs" and has columns "ID, WhatsNew, Welcome, Active".
My goal here is that if table "AboutUs" is affected as an "INSERT" or an "UPDATE" on any row, I want "PageInfo.DateModified" WHERE "PageInfo.Title = AboutUs" to be updated with "getDate()". Don't know if I'm clear enough but thanks in advance.
I would like to know how to add SELECT row to a table variable. It's not for my SELECT syntax(code following is just an ugly example) that I want help it's for the use of table variable. Your help will greatly appreciate!!!
ex : DECLARE @MyTestVar table ( idTest int NOT NULL, anotherColumn int NOT NULL)
SET @MyTestVar = (SELECT idTest, anotherColumn FROM tTest)-- This cause an error :-- Must declare the variable '@MyTestVar'. ???? What?
We are approaching the "go live" date of a big application upgrade, so while the application is being upgraded i was asked to lock out all users and backup all databases and make sure the data isnt changed during a period of time
It turns out, as one of my databases is being replicated to another server, i cant put that database in read_only mode, or restricted_mode, without removing the replication.
Removing the replication means i have to set it up again and that means another 3 hours added to an already cram-packed weekend without sleep!
How I can lock out the users to make sure there are no changes to a database other then read_only/restricted_mode/single_user ?
I need to estimate the effort required in writing some SSIS packages. Could anyone provide some pointers to the various factors (E.g. number of tables, source, etc.) which influence the effort estimate for SSIS packages?
In my SELECT query I have: MIN(a.orderdue) AS 'Oldest order date'
This works in that it brings through the oldest order date, however it brings through a date format like: 2015-06-11 11:30.000
So I amended the SELECT query to:
MIN (CONVERT(varchar(17),a.orderdue,103)) AS 'Oldest order date'
This brings the date through as 11/06/2015, which is preferable.
But I have noticed that doing this has affected the output: the MIN function no longer returns the first (oldest) date, but a completely different value.
Obviously my changing the formatting for the date has affected the MIN output. Is there any way I can amend the formatting of the date without this happening?
Got a good question to ask. At the moment, I do not have any control over the reporting server webserver. This is due to the company's policy. The webhosting is controled by antoher department.
Anyways, the question is the following:- Is there a way to customize the config file for the htmlviewer (css style sheet, rendering and others) for a specific client without affecting the rest ?
There are about 20 clients on a server, and I am responsible for one of them. I had customized my config file to render or allow only two formats for this particular client. Since I don't have any control over the websever, I just can't replace the config file without affecting the others. How do i do this ? I just want th config file to ONLY affect a certain client's HTMLViewer and not the others. I tried to do some research on this, but came up empty handed.
We have a HP server with windows 2003. MS sql 2005 was installed on it. The third party databases were installed. SP1 was never installed. This server (paahouentsqlp) PROD was cloned and placed on a vm server.
When server came up on vm enviornment the server name was changed to (paahouentsqlt) TEST. Nothing was done to the SQL environment. No registery entries were altered. No sp_dropserver or sp_addserver were ran. TEST server seems to be running ok.
I have attempted to install sp1 on TEST server (paahouentsqlt). The enumeration process takes about 1-2 hrs. When I finally get a screen all product selections are grey out except for SQL Server Native Client, Setup Support File, MSXML 6.0 Parser, SQLXML4, Backward Compatibility, and MS SQL Server VSS Writer. Than I'm prompted with a couple of NEXT screens, than Finish.
When I look at the product version it still shows it as the original 9.0.1399
from the December 2004 _Redmond Magazine_, "Finding Gold in Yukon":http://redmondmag.com/columns/artic...ditorialsID=838"Developers will also pick up the usual new-version enhancements to T-SQL,including error handling, recursive queries, a ROW_NUMBER function, a PIVOTrelational operator and more."ROW_NUMBER???? What possible purpose could that have???
I got an issue with encrypt and decrypt. I encrypted a data, say 'ok', then I decrypt the encrypted data, but what I got is not 'ok'. but if I encrypt a column, then after decryption, those data asr same with the original data in that column.
When using @original_{0}, how does this work if you are using a stored procedure instead of inline SQL? For example, if my update parameters are like this : <UpdateParameters> <asp:Parameter Type="String" Name="ProductType" /> <asp:Parameter Type="String" Name="OpportunityType" /> <asp:Parameter Type="Double" Name="Value" /> <asp:Parameter Type="String" Name="Probability" /> <asp:Parameter Type="Int32" Name="OpportunityID" /> </UpdateParameters>
And my stored procedure like this : CREATE procedure dbo.UpdateOpportunity ( @ProductType int, @OpportunityType int, @Value money, @Probability int, @OpportunityID int) as update Opportunity set ProductType = @ProductType, OpportunityType = @OpportunityType,[Value] = @Value, Probability = @Probabilitywhere OpportunityID = @OpportunityID Do I need to change both cases of @OpportunityID in my stored procedure to @original_OpportunityID for it to work?
I managed to get fuzzy grouping working. The relevant output (_key_in and _key_out) are stored in a new table that is a copy of the old table + fuzzy grouping columns.
How do i get SSIS to store the _key_in and _key_out in the original table? The new matching column _key_out refers to the new key: _key_in. How could i get SSIS translate that to a matching column that refers to my original key?
I have a tempdb that was created at 1Gig. I don't know why but I want to shrink it below the original creation size. Is there a way to shrink this file or create a new file and delete the old?
I have tried shinkfile and shrink database with no luck.
I restored a backup of a database running SQL Server in W2K to my own laptop (Windows XP) for report testing pourposes. The restore worked perfectly, but when I ran the store procedure that returns my "report" set I noticed that several of the fields within the result set are different, the number of rows and customers are a perfect match to the production report. The fields that are different are calculated fields that invoque a user defined function, which again are exactly the same on both databases. I tried dropping the stored procedure and the 4 functions and recreating them again but I get the same results, the number of rows, the customers and all "non" function calculated fields are perfect, only the fields calculated with the functions are wrong.
Does anyone know how to get the original Login name, while a context switch is in effect.. For example during the use of Original login to SQL is Wayne Then Execute as Test
Now I need to know that Wayne is the Login and not Test
none of the standard things work, they all use the current context (suser_sname, etc)... Books online includes the following text
SYSTEM_USER returns the name of the currently executing context. If the EXECUTE AS statement has been used to switch context, SYSTEM_USER will return the name of the impersonated context. Use the LOGIN() function to return the name of the original login during impersonation.
But I cannot find any function called LOGIN() anywhere?
Say I have a result set with two fields numbers and letters.
1 A3 A1 B2 B
The result set is ordered by the letters column. How can I select the distinct numbers from the result set but maintain the current order? When I tryselect distinct Number from MyResultSet
it will reorder the new result set by the Number field and return
123
However, I'd like maintain the Letter order and return
I have been using the below query to copy a record of data that exists in several draft tables to the original tables. how do i change this query such that i can input multiple records at one time so multiple records get copied to original tables from the draft tables
At this time when i feed mutiple requestids to my query it simply errors out
SET NOCOUNT ON GO DECLARE @oldrequestid varchar(50),@newrequestid varchar(50) DECLARE db_cursor CURSOR FOR SELECT RequestId from report_request_draft where requestid in (320762)
