Is there an easy way to combine two SQL Server 2005 databases into a single database? I want to take database 'A' and database 'B' and merge them both entirely into database 'C'.
Thanks!
It depends what you mean by "merge". If you have two disjoint sets of tables and want to transfer them into the same database structure, that's not a huge problem.
If you are needing to interleave or transform the data from A and/or B, they way to do it will be completely dependent on what you are trying to accomplish.
That's called "data conversion" in the business. It can be a full project in itself, there is no quick and dirty answer for your question.
I'm not sure if you want to do this by yourself or are looking for a tool that will help you. If latter is an option, take a look at RedGate's SQL Compare and SQL Data Compare. These tools will let you see the differences between the schemas(SQL Compare), as well as the data in each database(SQL Data Compare). Also, they're free for 14 days and fully functional during that period.
Hope this helps,

Right click the database and click export data, and then follow the wizard. Do the same for the other database.

I have a 25GB's text file with that structure(headers):
Sample Name Allele1 Allele2 Code metaInfo...
So it just one table with a few millions of records. I need to put it to database coz sometimes I need to search that file looking, for example, specific sample. Then I need to get all row and equals to file. This would be a basic application. What is important? File is constant. It no needed put function coz all samples are finished.
My question is:
Which DB will be better in this case and why? Should I put a file in SQL base or maybe MongoDB would be a better idea. I need to learn one of them and I want to pick the best way. Could someone give advice, coz I didn't find in the internet anything particular.
Your question is a bit broad, but assuming your 25GB text file in fact has a regular structure, with each line having the same number (and data type) of columns, then you might want to host this data in a SQL relational database. The reason for choosing SQL over a NoSQL solution is that the former tool is well suited for working with data having a well defined structure. In addition, if you ever need to relate your 25GB table to other tables, SQL has a bunch of tools at its disposal to make that fast, such as indices.
Both MySQL and MongoDB are equally good for your use-case, as you only want read-only operations on a single collection/table.
For comparison refer to MySQL vs MongoDB 1000 reads
But I will suggest going for MongoDB because of its aggeration pipeline. Though your current use case is very much straight forward, in future you may need to go for complex operations. In that case, MongoDB's aggregation pipeline will come very handy.
Would like to sort the (largely text) data by date tags first (separating the data by quarters, lets say, even if into different files). Then would like to perform standard functions like conditional sums on the data. Without a substantial programming/database background but with a willingness to spend a few days to learn, what's my best bet for a solution?
It sounds like you want to be able to do some queries on your data. I would look into a SQL database solution. The most difficult part would be getting your data into the database.
All of AWS's relational databases can import from text files:
Microsoft's SQL Server: http://msdn.microsoft.com/en-us/library/ms178129.aspx
Oracle: http://docs.oracle.com/cd/B28359_01/text.111/b28304/aload.htm
MySQL: http://dev.mysql.com/doc/refman/5.0/en/mysqlimport.html
I would base the decision purely on whichever one is easier to load your file. If you are budget constrained, you can download MySQL and not do this whole cloud thing. Just keep it on your local computer, assuming you have enough disk space to host the database.
After that's done, they all support SQL, which makes it very easy for you to query your data. If you don't want to write your own SQL, there are tools for you to create queries by drag and drop. But being a programmer, I highly recommend writing your own queries, or coming back here for some query help.
servers all sql server 2008, and win xp
i have the following task
create a huge database, DONE
distribute it to the 20 waiting servers!!
if there were two or three i would have taken the trouble of creating the db's on all of using sql server managemnt stdio
but i am guessing that there is an efficient way
please note,
only the copy of the database structure, the schema is needed not the values within the cells!
thank you
Or of course you should have been creating the scripts as you went along and putting them in Source control. Then you would have exactly which scripts you needed for this version of the software and be used to doing the same thing for later modifications. You would also script the data inserts for any lookup tables you need to build.
Not having that, you can script the entire database. or use a SQL compare tool. But I strongly urge you to start treating database code like all other code and scripting, storing it in source control and versioning it. Life is so much better when you do that.
What Gabriel McAdams has shown, or, Redgate SQL Compare does this very nicely also.
If you can spare the moolah, using a tool like Red Gate's SQL Packager is an option i have used in the past and it works well!
The tool can do a lot more as well and may not be worth the spend though if you do not need the other features!
In that case, Gabriels'option above is definitely the easiest one to go with!
I have a Databse "Product" in in sql 2008.I have another Databse "ORDER" in sql 2008.
Both exist in different servers.
Now the requirement is to Merge both databases, and test pointing the applications to this new DB.
Can anyone suggest the best way to accomplish this without losing the information?
I have 2 options.
1) Script the DB objects.(script both the DB and run this scripts inthe new DB)
2) Export DB
Which one in this is best or should i use any other methods to avoid errors.
I am new to SQL so please guide me with correct options.
Thanks

In my opinion the best way to achieve what you want is by just Exporting the database.
I think this is the best option because it's alot more safe then scripting the db's into a new one (a way to just get alot of frustration and errors).
Just try the exporting of your database first before trying to do anything with scripting (which obviously also takes alot more time). So try your fast solution first, and see if it will work.
(I see you are using sql-server 2008) Are you also using the management studio? If so, you can go into the tables in edit-mode and try to copy / paste rows into the new tables. I don't know how big your tables / DB's are, but this could also be an option.
Greetings,

As you say, two options are scripting or using the SQL server export/import wizard.
I've used both (for the same database as it happens)
A third option is to use Visual StudioTeam System 2008 Database Edition GDR.
In terms of a one time export and import then I'd recommend going with the wizard. This is very safe and also very straightforward. Particulary as you are new to SQL server, you want to take the approach that minimizes the risk.
The only downside to doing it this way is that it is perhaps a little less transparent than the other methods.
On the project where I merged databases I ended up using the scripting method but that was mainly because I had a project that was already using GDR to merge incremental database updates, so adding in a data merge script to that was a simple task - all changes needed to go through DBAs who unfortunately weren't very SQL literate (I know!) so keeping all the processes similar was a must.
I also took some of my learnings from scripting the data and applied them to setting up my reference data scripts, so the effort of scripting was not a one time cost.
Either way, the most important tip I can give is to back up the databases before doing any work on them.

I would like to compare two SQL Server databases including schema (table structure) and data in tables too. What is best tool to do this?
I use schema and data comparison functionality built into the latest version Microsoft Visual Studio 2015 Community Edition (Free) or Professional / Premium / Ultimate edition. Works like a charm!

Red-Gate's SQL data comparison tool is my second alternative:
(source: spaanjaars.com)
http://www.red-gate.com/products/sql-development/sql-compare/
http://www.red-gate.com/products/sql-development/sql-data-compare/
I like Open DBDiff.
While not the most complete tool, it works great, it's free, and it's very easy to use.
I am using Red-Gate's software:
http://www.red-gate.com
SQL Admin Studio from http://www.simego.com/Products/SQL-Admin-Studio is now free, lets you manage your SQL Database, SQL Compare and Synchronise, Data Compare and Synchronise and much more. Also supports SQL Azure and some MySQL Support too.
[UPDATE: Yes I am the Author of the above program, as it's now Free I just wanted to Share it with the community]
I'm partial to AdeptSQL. It's clean and intuitive and it DOESN'T have the one feature that scares the hell out of me on a lot of similar programs. One giant button that it you push it will automatically synchronize EVERYTHING without so much as a by-your-leave. If you want to sync the changes you have to do it yourself and I like that.
There is one tool with source code available at
http://www.codeproject.com/Articles/205011/SQL-Server-Database-Comparison-Tool
That should give flexibility as code is available.
dbghost is the best i have used to date. one of the best features i have seen is that it will generate SQL code to go between versions of a database based on the SQL you keep in source control, as well as a database. simple and easy to use.
I've used SQL Delta before (http://www.sqldelta.com/), it's really good. Not free however, not sure how prices compare to Red-Gates
Try DBComparer, it's free and fast:
http://dbcomparer.com/
Database Workbench can made it too
http://www.upscene.com/products.dbw.index.php
Cross database development
Use the Schema Compare and Migration
Tools to compare testing and deployed
databases, migrate existing databases
to different database systems.
you can also made it with database Comparer
http://www.clevercomponents.com/products/dbcomparer/dbcomparer.asp
I use it for Firebird and it works well.
Try dbForge Data Compare for SQL Server. It can compare and sync any databases, even very large ones. Quick, easy, always delivers a correct result.
Try it on your database and comment upon the product.
We can recommend you a reliable SQL comparison tool that offer 3 time’s faster comparison and synchronization of table data in your SQL Server databases. It's dbForge Data Compare for SQL Server and dbForge Schema Compare for SQL Server
Main advantages:
Speedier comparison and synchronization of large databases
Support of native SQL Server backups
Custom mapping of tables, columns, and schemas
Multiple options to tune your comparison and synchronization
Generating comparison and synchronization reports
Plus free 30-day trial and risk-free purchase with 30-day money back guarantee.
We are using an inhouse developed solution that is basicly a procedure with arguments of what you want included in the comparision (SP's, Full SP code, table structure, defaults, indices, triggers.. etc)
Depending on your needs and budget, it might be a good way to go for you as well.
It is quite easily developed as well, then we just redirect output of procedure to textfiles and do text comparisions between the files.
One good thing about it is that its possible to save the output in source control.

I've used Red Gate's tools and they are superb.
However, if you can't spend any money you could try Open DBDiff to compare schemas.
I would definitely go with AdeptSQL if you're using MSSQL. It's the least good looking but the most talented db compare tool amongst the ones I've tried. It can compare both the structure and the data. It tells you which tables exist on one db but does not exist on the other, compares the structure and data of the common ones and it can produce the script to synchronize the two. It's not free but has a 30 day trial (as far as I can remember)
I tried OpenDiff Tool . Great tool that is free and easy to use .
