I want to move a database from our testing server to my local server. I don't have the option of back up and restore since I don't have permission. So I decided to use the generate script option to create all the scripts for the DB and then move over the database to my local server. The problem I'm facing is that most of these tables have foreign key relationships and when I generate the scripts, they are being generated in alphabetical order and therefore my scripts are failing. Is there a way to generate scripts where the tables are aligned based on their foreign key relationships? If not, is there some other way to achieve this?
You have to change some settings on advanced options. Remember setting the right compatibility level of your target server, this option can mess up your script.
I've used this tool to migrate many times from SQL Server 2019 to 2019 (Windows and Linux) and to 2012.
One thing you have to check before saving your script is the encoding when you have to include data.

I have an application that has been released for several years. I have updated the SQL Server database around 90 times and each time I have created an update SQL script, so when the user runs the new software version the database is updated.
I would like to amalgamate all the updates into a single SQL script to make deployment faster and simpler, is there an easy way to do this? I presume I could simply grab the latest database after it has run through all 90 updates via SQL Server Management Studio?
EDIT
For clarification; the software I wrote automatically applies new database updates when the user downloads the latest version. This is done via C# / .Net and look for an embedded sql script on startup in the format XX_update.sql calling each script one by one i.e.
1_update.sql - this creates the tables and initial data etc. This was my initial release database.
2_update.sql - updates to the initial database such as adding a new SP or changing column datatype etc
3_update.sql
4_update.sql
...
90_update.sql (4 years and lots of program updates later!).
Ideally, I would install my software and create a brand new database running through all 90 update scripts. Then take this database and convert it into a script which I can replace all 90 scripts above.
This is too long for a comment.
There is no "easy" way to do this. It depends on what the individual updates are doing.
There is a process you can follow in the future, though. Whenever an update occurs, you should maintain scripts both for incremental updates and for complete updates. You might also want to periodically introduce major versions, and be able to upgrade to and from those.
In the meantime, you'll need to build the complete update by walking through the individual ones.
I use a similar system at work and while I prefer to run the scripts separately I have amalgamated several scripts sometimes when they have to be deployed by another person with no problem.
In SQL Server the rule is that as long as you separate the scripts by go and use SQL Server Management Studio or another tool that process the batch separator properly there is no problem in amalgamating it, because it would look like separate scripts to SQL Server (instead of being sent to SQL Server as a one big script the tool send it in batches using the go as the batch separator).
The only problem is that if you have an error in the middle of the script, the tool would continue sending the rest of batches to the server (at least by default, maybe there is an option for changing this). That is why I prefer when possible using a tool to run then separately, just to err on the safer side and stop if there is a problem and locate easily the problematic command.
Also, for new deployments your best option is what you say of using a database that is already updated instead of using the original one and apply all the updates. And to prevent being in this situation again you can keep a empty template database that is not used for any testing and update it when you update the rest of databases.
Are you running your updates manaually on the server. Instead, you can create a .bat file, powershell script or a exe. Update scripts in your folder can be numbered. The script can just pick up updates one by one and execute it over the database connection instead of you doing it.
If you have multiple script files and you want them to combine into one,
rename these as txt, combine, rename the resulting file as sql.

This is easy. Download SQL Server Data Tools and use that to create the deployment script. If there's no existing database, it will create all the objects, and if targeting an older version it will perform a diff against the target database and create scripts that create the missing objects, and alter the existing ones.
You can also generate scripts for the current version using SSMS, or use SSMS to take a backup, and use a restore to in an install.
Is there a tool that will let me generate a single script containing all tables and views? Sql Publishing Wizard drops everything (so all data is lost) and recreates it. It does have an option to not drop, but in that case, it doesn't update tables that exist (if any columns have changed).
In SQL Server Management Studio 2008 you can right-click on a database in the object explorer, go to Tasks > Generate Scripts..., and that will give you the option to choose not only what object types you want to script, but whether or not you want to script the drop as well.
When you are making changes to existing tables, you should be writing alter table scripts to make the change and then putting them in source control like any other code. Then when you deploy a set of changes, you run the scripts you created for that deployment.
Otherwise, yes use SQL compare.
Should you look at the Red Gate products specifically SQL Compare. They'll handle any situation you could need concerning script generation and database synchronization. (You can get a trial license too, to try it out and see if it is what you need.)
Have a look at this tool can be used which has the capability to generate the create and drop scripts for the SQL server objects, provided in a configuration file.
This tool uses the same mechanism as SSMS tool uses to generate the script.
SQL Server Script Generator Tool (via C#)
Have a look at these:
WinSQL (Lite edition is free, other versions are reasonably priced + free trial)
OpenDbDiff (free)
You can also check out MyDbUtils which can create scripts for:
Stored Procedures
Functions
Views
Triggers
hope that everybody here is OK.
We are using VS 2008 as development tool, TFS 2008 as version control as well as build automation. Some of our developer use dbpro for databases changes and some use SQL Server management studio.
I am trying to automate build for Web Application built using C# and VB.Net.
Our scenario is such that we have a central database to which our web application connects.
Whenever we supply our clients with a new functionality or a bug fix, we supply them incremental builds.
The SQL script is checked into source control for every incremental build when they have made and tested there changes on our central DB Server.
I want to generate Differential script that can be run at the client as an incremental update script. Now to come about it is a problem. Sometimes our developers tend to forget the database change-sets and the script in the source control is missing an SP or a two.
Also, sometimes we need to insert default data into some of the tables that have strict stringent values and not test values. Like a table that contains Services provided by the panel, we add a new service name, signature, credentials and service address, etc etc in the ServiceTable. Besides this many other tables may have test data that may not be needed.
If we use DataCompare, it will generate changeset for required data (important for client to enable certain services) and our test data that was added to the database as a result of our testing of the functionality or bug fix.
Currently i am using SQLSchemaCompareTask (from Visual Studio 2008 Team Database Professional Power Tools API) in the TFSBuild.proj file of the build definition for TFS 2008.
Using SQLSchemaCompareTask, the script generated contains database names like [dbo]. etc which are not desired as the script fails when run against SQL Server 2000 databses (Some of our client still use SQL Server 2000) databases as teh backend of the application.
Also default data can't be generated by this process.
To overcome this problem, i have to come up with a solution that can compare databases and generate script automatically that does not have to be manually reviewed again before being sent to the client.
Please suggest effective methodology of such SQL script generation and suggest whether two different databases may be used or something ? Is there any toolkit or api that can enable build automation for SQL Server databases?
Thank you all.

Steve
Try to use SQL Examiner Suite for this:
http://www.sqlaccessories.com/SQL_Examiner_Suite/
The tool compares both schema and data and produces synchronization scrips (or differentials scripts). You can automate script creation with supplied command-line tool.
Rather than collating many individual change set scripts (and therefore occasionally missing objects out), why not use schema compare and data compare to create a single script from your database project using a database equivalent to your client's on the target? This should create a script tailored to their requirements.
In data compare you can exclude test data records that you don't want pushed to your client by unchecking them in the lower grid.
I was wondering if there is a way to automatically append to a script file all the changes I am making to my columns, tables, relationships etc...
The thing is I am doing a lot of different changes on a TEST db and the idea will be to apply this change script when I move the test db to production... hence keeping production data but applying all schema and object changes.
Is there an easy way to do this? Can it also migrate database diagram changes?
I have seen how you can create a change script each time I do a change but this means I have to copy and paste into a master file. Actually pretty easy!
I was just wondering if I was missing something?
Do not make changes to the test server using the UI. Write scripts and keep them under source control. You can test your scripts starting from backups of the live data and you can tune yoru scripts untill they achieve the desired result. Then you can check in the scripts for reference and later apply them on the live server. See this article Version Control and Your Database.
BTW, check out the SSMS toolpack, I think it may do what you want (I'm not sure). My advice stand none the less: version your schema, use explicitly created/saved scripts, use source control.
There's no way to directly generate a "delta" script in SSMS.
However, if every time you publish changes, you script out the entire database, including data, to SQL using the SQL Server Database Publishing Wizard you should be able to extract diffs between the versions and get your deltas that way.
If money is no object, you can purchase Visual Studio Team System Database Architect edition and use its fantastic database comparison tools to generate and version control exactly the diffs you want.
Try using TableDiff , that came with SQL Server 2005.
SQL Server 2005 TableDiff Utility

We have the process where when a developer gets done with a change, they then script it out and check it into Subversion. In Subversion we have a folder for Tables, Stored Procs, Data, etc. They script it out so it is repeatable (i.e. don’t insert the new data if it is already there.) This is important to do anyway so you keep the history of changes for a given object in the database.
In the past, we would just enter each of the files that we wanted scripted out into a text file (i.e. FileListV102.txt). When we were ready to make a release we would do “get latest” on all of the files (from VSS back then.) We then had a simple utility that would read the “file list” file and open each of those files in turn concatenating them into an output file. That is pretty easy to code.
We outgrew that and now we have a release management tools (which can be found here and will be on sale mid September), that takes all of the files and creates a big SQL script file out of it. It does it in the order that you would expect based on the folder names – so files found in the "Tables" folder are done before those in the "Data" folder, etc.
Either way, once you are done you have a big SQL script file that you can then apply to a fresh copy of production and that is what you test against.
I know I'm way late to the party, but I just wanted to add that there are tens of third party products out there. Some are very good, some are very cheap or free, and some are a mixture. I listed 22 here:

We have been using a relatively new software called Kal Admin.
It has Change Management feature and let distributing selected changes to other databases very easily. We used to do it by comparing two databases but it not satisfy our need for change tracking.
BTW Kal Admin has Metadata and data compare capabilities as well.
I have been developing in VB.NET and SQL Server 2008 for a while now, but haven't got into live installs yet. In the database system I used be on it had the ability to archive multiple tables into a .dga file, as it was called. I could then restore the .dga file into another database or on another server.
I'm looking for the easiest way to accomplish something similar in SQL Server.
If you want to transfer specific tables, then using Data Transformation Services (right click on the database in SQL Server Management studio and select "Import Data" and it will bring the dialog up for it). Of course, this assumes that you have both databases available to you.
If you are comfortable with replacing the database as a whole, you can easily backup the database and then restore it into a new one through SQL Server Management studio (or through calling the appropriate SP).
I would go for one of the following :
From MS SQL Management Studio, right click on the database / Tasks / Generate scripts
From Visual Studio, in the Server Explorer tab, "publish to provider"
Both will launch a wizard allowing you to export the tables you want the way you want (including data or not, creation scripts or not, etc etc.)
If you want to move tabless without data, the simpliest thing is to script the tables you want and run the script.
We script all our db changes and commit them to subversion and then run them as part of the deplyment process.
If you want to put the whole database on prod including data (scrub out test records first!), then do a backup and restore onthe other server.
For future changes, wescript all our db changes and commit them to subversion and then run them as part of the deployment process. There also are tools that look at the structural differnces bewteen the two servers and creates scripts. REd-Gate's SQL Compare is really good for this.
In addition to HLGEM's suggestions, you can look into SSIS if this is an ongoing process.
