How To Apply Table Changes In My Production Database?
Sep 29, 2007
Here is the scenario:
- I have one production database and one test database.
- In the test database i have done a few changes on the structure - mostly adding new fields in the tables.
- Now i want to apply the table changes to my production database.
Does anyone have any suggestions on how i should do that?
I mean, of course i could just manually check every field and update the changes - but that could take a while -
i guess there are some better ways this could be done, like:
- backup data
- delete tables
- recreate tables using structure of test database
- reinsert data
Is this the correct way? Are there any easy ways to do this?
The changes i made should not make problems regarding data that is already stored (like changing a string field to int)
Hi... I'm reading the MS Press 70-442 Self-Paced Training kit, and I'm having problems with this example. I'd like help getting it to work correctly, or understand why it is isn't working the way I planned.
On page 67, the lab is about the APPLY operator (CROSS APPLY and OUTER APPLY). I first have to input a sample table-valued function into the AdventureWorks database:
Code Block CREATE FUNCTION fnGetAvgCost(@ProdID int) RETURNS @RetTable TABLE (AvgCost money) AS BEGIN WITH Product(stdcost) AS ( SELECT avg(standardcost) as AvgCost FROM Production.ProductCostHistory WHERE ProductID = @ProdID ) INSERT INTO @RetTable SELECT * FROM Product RETURN END
and then run a sample T-SQL statement
Code Block SELECT p.Name, p.ProductNumber, Convert(varchar, cost.AvgCost,1) AS 'Average Cost' FROM Production.Product p CROSS APPLY fnGetAvgCost(p.ProductID) AS cost WHERE cost.AvgCost IS NOT NULL ORDER BY cost.AvgCost desc
My problem is with the WHERE clause... According to page 56, CROSS APPLY returns only rows from the outer table that produces a result set, so why do I need to explicitly filter NULL values?
When I remove the WHERE clause, the query retrieves lots of NULL AvgCost values.
Again, according to page 56, it is the OUTER APPLY that returns all rows that return a result set and will include NULL values in the columns that are returned from the table-valued function.
So, in short, I don't see the difference between CROSS APPLY and OUTER APPLY, using this example, when I remove the WHERE clause?
(Please refrain from introducing another example into this question.)
I am interested in applying 7.0 log files to 2000 database, that has been previously restored from a 7.0 version database. Assuming that the original database is one in the same, is this possible?
I'd like to select the last unshipped order, or if none is open, the last shipped order, for each customer. I noticed that all the examples on line for OUTER APPLY involve table-valued functions, but I have read (in a book I don't have here) that a subquery can work. The following shows what I want, but it isn't valid syntax: SELECT c.CustomerName, oa.OrderNumber, oa.Status FROM Customers c OUTER APPLY ( SELECT TOP 1 CustomerID, OrderNumber, CASE WHEN ShipDate IS NULL THEN 'due ' + CAST(DueDate AS VARCHAR) ELSE 'shipped ' + CAST(ShipDate AS VARCHAR) END AS Status, CASE WHEN ShipDate IS NULL THEN DueDate + 1000 -- Give open orders priority. ELSE ShipDate END AS SortOrder ORDER BY SortOrder ) AS oa ON oa.CustomerID = c.CustomerID
Hi I have a production table in SQL Server 2005 that has approx 500,000 records---every 6 hours this table needs to be truncated and filled
The basic SSIS package uses a script compentant and imports the data into a staging table which has the same structure as the production table. I have a final Execute SQL Task that Truncates the production table and does a Insert into production-select * from stage table.
Takes around 30 seconds to run this last Execute SQL Task--problem is there is a risk that our webservice will query this table during the Execute SQL Task and return incorrect results.
Q1: In this last Execute SQL Task if I used a BEGIN TRANSACTION and COMMIT TRANSACTION; will this be any quicker ?
Q2: In this last Execute SQL Task- would it be better to use a RENAME TABLE technique in TSQL--any code examples ??
Q3:Is there any way in TSQL I can compare EVERY FIELD in two tables ie Stage and Production which have identical data structures and figure out a way to update only the records that changed? Is SQL Server Replication the best way to do this
I have two tables 1) tblCustomer (ID, Name, City) 2) tblemp (ID, NAME, Dept.ID, tblcustomer.ID) Both the tables have ID as PKA emp can be either assigned a) All customers b)single customer c) NO customer Pls note:- there will never be 2 or 3 customer linked to emp (my actuall requirement tables are different but to explain i am using the above tables) I know how to assign single customer......but had problem how to link all customers and "no customer" Please tell me if the following solution is right?1) I will manually insert a record in tblCustomer with id 0 as " all customers" and will not allow the user to delete it 2) store null in FK if it is "no customer" Also please tell me is it ok to store one more value in tblCustomer as -1 and take it as "No customer" I have a DDL in the Employee page which should be displaying the names of allthe customers with 2 extra values "ALL CUSTOMERS" and "SELECT" Select is the default value in DDL which says "NO CUSTOMER" selected yet Thank youSara

If I have a database backup from sunday, and a failure occurs monday... Can the backup .mdf and .ldf files be attached, and the backup log after the point of failure be applied to them? The problem I am having is it looks like you can only restore from a .bak file, and then apply the log at the point of failure. IT doesn't look like you can restore the .ldf/.mdf files, and then apply the backup log from the point of failure.
Can someone please help? I'm in desparate need of fixing this !
I have a table (named table1) with 20million rows. It takes around 11 minutes to apply the primary key to this table. There are some tables with over 100 million rows so based on the previous time if my calculations are correct it will take close to an hour apply this primary key for tables with around 100 million rows.
My current solution is to create another table (named table2) with no indexs or primary keys. Pump over only like 5 days worth of data, then apply the primary key. Then have a script that will eventually populate table2 with the rest of the data gradually. When I say gradually I mean like insert like every 100k per hour or something. Keep in mind this table2 is heavily updated with new records.
I have an issue where i am mandated to enforce RI on an applications database (a good thing). but I have several common lookup tables where many of the "codes" reside for many different code types. I also have the mandate that i cannot change the underlying DDL to make composite keys to match the codes table PK. I am currently looking at creating indexed views on top of the Codes table to seperate the logical tables it contains. This is several hundred views.
I do know that I do not want to write several hundred triggers to enforce RI. Table schema below, the CdValue column is the column that is used throughout the hundreds of tables that use this codes table, and their corresponding column is not named the same.
CREATE TABLE dbo.CodesTable ( PartyGrpId INT  NOT NULL  , CdTyp  VARCHAR ( 8 ) NOT NULL  , CompId INT  NOT NULL  , CdValue VARCHAR ( 8 ) NOT NULL  , CdValueDesc VARCHAR ( 255 ) NULL  , AltValueDesc VARCHAR ( 100 ) NULL
[Code] ....
I did though run into one forum where a person brought up a great idea. Filtered Foreign Keys, what a novel concept, if it could work it would make so much less code to fix an issue like this.
ALTER TABLE dbo.BusinessStatus WITH NOCHECK ADD CONSTRAINT FK_dbo_BusinessStatus_CodesTable FOREIGN KEY (LoanStsDtCd) REFERENCES dbo.CodesTable (CdValue) WHERE CdTyp = 'Status'
I have a non-partitioned table (TableToPartition) and I want to apply an existing partition scheme (PartSch) to it using a query. I didn't find any option so I used the StorageCreate Partition wizard to generate the script.why this clustering magic needed if it is dropped at the end? Isn't there another way without indexing to partition a table, say something with ALTER TABLE? (SQL Server 2012)
BEGIN TRANSACTION CREATE CLUSTERED INDEX [ClusteredIndex_on_PartSch_635694324610495157] ON [dbo].[TableToPartition] ( [ID] )WITH (SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF, ONLINE = OFF) ON [PartSch]([ID]) DROP INDEX [ClusteredIndex_on_PartSch_635694324610495157] ON [dbo].[TableToPartition] COMMIT TRANSACTION
I need to translate a user€™s regional setting into one of our own language codes before I send it through as a filter to the model query. If our language codes were the same, the filter would look like this in the report filter - Language Code = GetUserCulture() Which translates to this in the database query (for us english) - table.language_code = 'EN-us' And of course I need it to look like this - table.language_code = 'ENG'
I would like the logic to be globally available to all report writers (ie not forcing each report writer to have an iif or case stataement). I was thinking custom assemblies or maybe a database function, but at this level of the filter, I cannot seem to figure out how to embed a database function call to apply to the filter criteria like this Language Code = dbo.ConvertFcnIWrote(GetUserCulture()) Or how I would access the custom assembly in the filter expression.
Do you have a recommended implementation for this situation?
I am using CROSS APPLY instead of UNPIVOT to unpivot > one column. I am wondering if I can dynamically replace column names based on different tables? The example code that I have working is based on the "Allergy" table. I have thirty more specialty tables to go. I'll show the working code first, then an example of another table's columns to show differences:
select [uplift specialty], [member po],[practice unit name], [final nomination status] ,[final uplift status], [final rank], [final uplift percentage] ,practiceID=row_number() over (partition by [practice unit name] order by Metricname) ,metricname,Metricvalue, metricpercentilerank

We often have to migrate changes to sql server 2000 databases fromdevelopment to production. Normally we dump the sql from Enterprise Managerfor production and development and do a diff (using CSDiff - downloadable forfree).From the diff information we create some scripts to add new tables or alterexisting tables as required. This is time consuming and error-prone.I am now trying the following:1. Backup up the Development database2. Delete the Development database3. Restore the Development database as Development_Backup3. Use the the sql script to create the new Development databasestructure from scratch4. Use Data Transformation Services to migrate the data fromDevelopment_BackupThe problem is that many of the 'sys' tables are empty. For example table'sysforeignkeys' is empty.Is there an easy way to rebuild the data in the 'sys' tables?Thanks
We are installing an application with MSSQL database at our users place.Now we have two instances of the same database:- developing database, on which we are working at- production database, which is at our user's place.That 2 databases would have to be syncronised.Users will of course enter some data into production database. How can wechange the production database do reflect changes we have made on thedeveloping database?D.--
My applications group wants to do a table transfer from one server to another as a means of refreshing the information on the target on a scheduled basis. That means that reports could be running against the target table during the transfer. This has introduced erroneous reports because the object transfer initially truncates the table, then transfers the data. If reports are running during the transfer, they might retrieve no data or only part of a table. I wrote a procedure to make a copy of the table to be transferred, then transfer that new table to the target machine, then drop the target table, then rename the transferred table. Now, I have the slightly smaller problem of doing a DROP TABLE when users are accessing the table. I can't set the database to 'dbo use only' because there are other tables in the database that must be available. Is this really a replication application?
I developed an asp.net application in visual web developer 2005 express edition and SQL sever 2005 express with Advanced services. The application has been deployed and iam wondering what tools are availabel to for backing up my data. Are there any tools i can use to back-up my database. Iam not talking of third party tools but tools a vailable in sql sever 2005 express with advanced services or visual web developer express. OR can write a vb.net Sub procedure that i run and have my database backed up. If so where can i start or what other options may i explorer.
Can anyone help me in this issue: How do we replicate database changes (like tables) from QA to production without losing Production data. We already tried using the DTS export but it is dropping the destination tables before export which will result in data loss in the destination database.
We have a database in production which has free space about 200 GB in Data files and Index files, I want to shrink Data files and Index files.If I do incremental shrink in daytime does it hurt the performance of the database or please advise what is the best practice.
I have a production database with a backup job that creates files with thenaming convention dbname_db_200503291800.bak. I want to schedule a restorejob that will retire yesterdays backup. How can I write my restore statementso that it will specify the backup file with yesterdays date.Thanks
we are having 2 prodction servers in our environment. and we are planning to perform database mirroring between them.i want to mirror server 1 databases to server2 and server 2 databases to server 1. is this possible??
if possible , can any one give me a link to document where i can find more info on this, or send me the steps what i need to done for this...
Hi all, I have a site which used a SQL Express database. On my development machine, it works perfectly. As soon as I move it to the production machine, it doesn't work at all. I am pretty confused by what is going on and I really don't want to install Visual Studio on my production machine just to debug it. I am hoping someone might have an idea what could be happening. Oh, and I have tried setting Everyone to Full Control on the App_Data directory just to test. Still breaks. Below is my web.config connection string: <connectionStrings> <add name="database_sqlexpress" connectionString="Data Source=.SQLEXPRESS; AttachDbFilename=|DataDirectory|MyDatabase.mdf; integrated security=true; user instance=true"/></connectionStrings>
We're using SQL Server 2000 as back end in our web project. The problem is we've 3 different copies of same database - one each for Development, Test and Production sitting in 2 different machines.
My question is - is there any tool for comparing the objects (tables, stored procedures, etc) ?
I have been looking for some documentation that would support or rejectmy opinion on Production -vs- Development naming conventions. Ibelieve that each environment should be housed on separate servers withidentical names, access, users, stored procs....... If you eitheragree or disagree with this methodology, I would appreciate your input.TIA,Bill
Is there any tool available to migrate the data from the SQL Server test database to SQL Server production database. Data Migration should be based on a condition which can be given as an input for a table by the user. The dependant tables also should be migrated based on the condition. i.e data subsetting based on the matching conditions.
Ex : Salary > 2000
The rows of the table which matches the condition alone need to be migrated for the corresponding table. Also its dependant table's rows should be migrated based on the given condition. Please help me with a tool which can automate this.
I am trying to refresh a test database with data from a production database. Both database structures are identical, e.g. constraints, stored procs, PK, etc. I am trying to create a package in SSIS that accomplishes this task and I am having extensive problems. The import export wizard is out of the question because the constaints are not carried over, plus when I try to refresh the data using the import export wizard, it fails on 1 specific table because of a column in that table named "Error code". I think "Error code" is a micrsoft keyword, so it fails on this column. Does anyone know a workaround that I can do to accomplish this simple task, that could be completed in minutes using DTS. I understand that SSIS is not as straight forward as DTS, but this task is something that DBA's do on a regular basis and therefore should not be this difficult.
