The On-premises Database have tables and those tables columns types are UDTs, for this reason created same UDTs and tables using these UDTs on the cloud.
But when trying to syncing them its shows error not supporting UDTs, So am I missing something or is there any workaround to do syncing with UDTs?
Here if SQL Azure allows to create UDTs & also allows to create tables using those datatypes, then why not allow to sync?
FYI "SQL Azure" is called now "SQL Database" so if you find reference to Windows Azure "SQL Database" you can consider applied to your requirement as well.
SQL Database does not support user-defined data types, extended properties, Windows authentication, or the USE statement.
However the November 2010 update to SQL Server 2008 R2 includes support for SQL Database. The Generate Scripts Wizard now allows you to script for database version SQL Database so the scripts generated are directly compatible to be executed on SQL Database. The scripts thus generated are compatible with SQL Database and can be compiled on SQL Database without any further modifications. So your UDDT or custom data types can my transferred to SQL Database through this migration script.
If your Database is pre-SQL Server 2008, you can use the "Schema Migration with pre-SQL Server 2008 R2" section from this article.
unfortunately, there is no workaround at this time. The Data Sync Service is largely based on Sync Framework and it doesn't support UDT as well. The Data Sync Service supports spatial data types in the latest release though.

I am working on migrating an application from one server to the other. According to the connection string of this application, it is touching different databases. Meaning a view query in DB1 will touch a table in DB2. So while migrating this application, I constant get to see chain of 'Database unavailable' errors and every time I see such error, I have to migrate that specific database.
I am wondering, since we have ER diagrams to know about relationships between tables in a database, is there any way in SQL server to know the relationships/linkages between different DATABASES in a server? Are there any tool that does this?
Depending on number of databases you have, here would be a somehow quick way you can find that out (number of required search = number of available databases in the server):
Use 'SQL Search' application of Red-get
(https://www.red-gate.com/dynamic/products/sql-development/sql-search/download)
and search for the other database names one after another by selecting
your database of interest. Select all objects.
If you have metadata oriented design (a Stored Procedure looping through the names of different other Stored Procedures / Functions from different databases which are stored in a table as metadata and executing them with a wrapper Stored Procesure), then you will have make use of SQL Locator software (http://www.sqllocator.com/Downloads.html) to search for database names in SQL Table values.
Both of the above software are free.
You need to have SSMS (SQL Server Management Studio) installed to be able to use this application. After installation, ‘SQL Search’ will be directly available in your SSMS as an add-on.
SQL Locator can be directly used by providing the SQL Server name and your SQL Server credential.
Note:- The above steps will help you find out the referenced databases from a certain database within the same SQL Server. If you need to find out databases from Linked Server (I do not believe your question is asking that anyways), then you will have to smartly utilize the same above tools to find the external server reference by searching the external server name.
Is it possible to query (or better, join) data from two different database systems? Let's say I have postgresql and SQL Server and I want to join a table from postgres to a table in SQL Server?
It doesn't matter which programming language.
What about utilizing a linked server? I use one to query an AS400 and join the results back to Microsoft SQL Server.
Quote from Microsoft documentation:
Configure a linked server to enable the SQL Server Database Engine to
execute commands against OLE DB data sources outside of the instance
of SQL Server. Typically linked servers are configured to enable the
Database Engine to execute a Transact-SQL statement that includes
tables in another instance of SQL Server, or another database product
such as Oracle. Many types OLE DB data sources can be configured as
linked servers, including Microsoft Access and Excel. Linked servers
offer the following advantages:
The ability to access data from outside of SQL Server.
The ability to issue distributed queries, updates, commands, and transactions on heterogeneous data sources across the enterprise.
The ability to address diverse data sources similarly.
I have this SQL Server 2005 DB and we are upgrading to a new DB in SQL Server 2008. The schemas would be slightly different between the databases. What would be a best option to copy data from the old DB to the new DB.
Define "slightly different". Integration Service is probably the way to go.
Since the schemas are only slightly different, I would suggest making a full backup of the SQL2005 DB and restoring it on the SQL2008 server. Once you have the direct copy, use a script to migrate the data on the few tables where the schema is different.
It really depends on the definition of slightly.
Use Integration Service to design a whole package, or you can connect to the 2005 instance from within 2008 SSMS and right click on the tables and select "Import Data". This will bring up an Wizard that will do the work for you (through SSIS) and let you copy the data right over.
Another option is to use SQL Server Data Tools, which is a new tool from MS that has a schema compare tool where you can actually generate the scripts to create the tables and related objects.

Does anyone know if Data Quality Services in Sql Server 2012 can be used against Oracle databases to improve their quality? I've had a look around the Sql Server site and can't determine if it can or not.
Thanks,
Steve.
There are two ways to use Data Quality Services over Oracle DBs.
Via the DQS SSIS cleansing component - you can use this as part of an SSIS flow that retrieves the data from the Oracle DB, cleans it within the SSIS flow using the DQS component, and then sends it back to the Oracle DB.
Via the use of the Linked Server functionality of SQL Server. See http://social.technet.microsoft.com/wiki/contents/articles/7540.accessing-your-data-on-remote-servers-for-dqs-operations-by-linking-servers.aspx for more information on how to do this.
I have a SQL server database (Tables, Views, SP...). I need to convert this database to Oracle 10g. How can I do it?
Transferring the data will be easy; SQL Server integration services can do that, or Oracle's SQL Developer.
However, views and stored procedures are different between Oracle and SQL Server. SQL Server uses T-SQL, Oracle uses PL/SQL. These are not very compatible and I don't know a tool can automatically convert between the two. If your database relies on specific T-SQL features, you will need a developer to do the conversion.
Get the jTDS jdbc driver from sourceforge.
Add it to Oracle SQL Developer.
Tools > Migration > Migrate
Create a migration repository in your new Oracle database.
Create a new migration project.
Point it to your SQL Server database.
Convert it - mind the data types.
Migrate the data:
online row-by-row inserts over JDBC. Fine for SMALL/test boxes.
offline - use micrsosoft's unload utility to pull the sql server down to flat files. SQL Developer will create SQL*Loader scripts to put them over into Oracle.
If you have GoldenGate licensed, use that to move the data over and to synch changes from one system to the other in case you need to keep both up and going.
Start looking at the migrated T-SQL procs and functions. SQL Developer will leave comments for code blocks it wasn't able to translate...but you will need to TEST and VERIFY every single translation. Customers can see upwards to 80-90% translation rates for their T-SQL, but it could be as low as 50%...it just depends on the nature of your code.
The entire process is described here.
I wrote a white paper, with Sybase ASE as the example source platform, here. The process is identical for SQL Server. It has step-by-step guidance with screenshots.

There is step by step documentation including videos on how to migrate SQL Server to Oracle DB. You find it here:
Migrating from Microsoft SQL Server to Oracle
Or you can use a tool to do the job for you like Ispirer - Migrate Microsoft SQL Server to Oracle
You basicaly setup an Oracle Server, once its ready you migrate your tables using a software made for that. I guess this script can do the job:
