Microsoft refers to creating an instance of a SQL Data Warehouse on Azure (NB NOT SQL Database), but there is no instance there that I can see. Please see attached screenshot of the Azure Portal Marketplace after typing in "SQL Data Warehouse".
This is part of their Data Science Associate Certification (Step 1 here: https://learn.microsoft.com/en-gb/learn/modules/understand-the-sql-dw-connector-with-azure-databricks/2-setup-the-environment) so would really appreciate if anyone can advise on how to get around / resolve this ??
NB if I try to create instead a SQL Database I come unstuck at step 4 in the above link as there is no option for "Select Performance level".

SQL Data Warehouse is now renamed as "Azure Synapse Analytics."
This is now Dedicated SQL Pool(formerly SQL DW)
Please create Azure SQL Data Warehouse database using the following method.
Click Create a resource in the upper left-hand corner of the Azure portal.
Select Databases from the New page, and select SQL Data Warehouse under Featured on the New page.
Fill out the form.
Select an existing Server or click Create new to create and configure a new server for your new database.
When finished, make sure you create a firewall rule that adds your client IP so you can connect to your database.

I have tables from my SQL Server 2008 R2 that have a schema. I manage to transfer some tables to sql developer but the tables with schema did't transfer. How to do?.
You can use DTS (Data Transformation Service) at SQL Server Side or you can configure Gateway at oracle side. To Use DTS you should have oracle client on the machine where you are executing DTS.
DTS will ask you for source and destination and it's credential. So as you need to migrate from SQL to Oracle. In source tab select "Microsoft OLEDB Provide for SQL Server" as Data Source, Put IP Address / Server Name in Server Name DDown. If you have Window Authentication then let it be and select database and go to Next. If you have login ID and Password, select SQL Server Authentication put Login Id and Password, Select you database and then click on Next button.
In destination Tab select "Microsoft OLEDB Provider for Oracle", then click on Properties. And put TNSName into Server Name (You configured using NETCA in Oracle Client on the machine) and LoginId and Password.
After you get connected it will display to use query or complete table, you just click on next without selecting any option.
Then it will display all tables from source, select the table you need to migrate then click on next till finish.
For Gateway configuration, take help from this link.

I’m trying to copy a SQL Server table, schema and data, from Server A to Server B. The SQL Server table is just a reference table which hasn't been populated for some reason on Server B. Can anyone advise how the entire table could be copied across please? On SQL Server 2000/2005.
So far we've tried a long-winded approach by copying the .mdf and .ldf files from Server A to Server B with a plan to then copy the table across into the Server B database but we are having some difficulty re-attaching the database to Server B.
Please can anyone help?
Kind Regards

Using SQL Server Management Studio (SSMS):
In Object Explorer right click on source database name, Tasks.. -> Generate Scripts.. - opens Generate and Publish Scripts dialog. Click Next to choose objects, choose "Select specific DB objects", expand Tables, choose your table. Next, setup script destination, for example New query window and (important step!!) - click Advanced, and set "Types of data to script"="Schema and data" and "Script USE DATABASE"=False, OK, Next, Next, .. wait .. Finish. Now you have got complete SQL script to reproduce this table with data. Connect to destination DB and run it.
Tested with SSMS 2014, but as I recall this feature should be available starting from SSMS 2005.
you can use the import/export data wizard in management studio, the wizard will create for you a new table in the server B with the same structure of the table in the server A. before using it you need to have at least one database in sever B.
This confirms why this is one of favourite forums.
Both these methods work beautifully :
Generate Scripts (when altering Types of data to script"="Schema and
data")
Export and Import
Interestingly Generate Scripts works with SQL Express perfectly but the Export method does not save unless you have at least SQL Server Standard Edition.
Thanks so much everyone
Cheers

Try this:
SELECT * INTO destination FROM source
But, it will not copy the indexes and key information or you can also try import/export data task from SSMS.
I am trying to run following SQL:
INSERT INTO Suppliers ( [SupplierID], [CompanyName])
Select [SupplierID], [CompanyName] From [AlexDB]..Suppliers
and got an error "reference to database and/or server name in is not supported in this version of sql server"
Any idea how to copy data between databases "inside" the server?
I can load data to client and then back to server, but this is very slow.
I know this is old, but I had another manual solution for a one off run.
Using SQL Management Studio R2 SP1 to connect to azure, I right click the source database and select generate scripts.
during the wizard, after I have selected my tables I select that I want to output to a query window, then I click advanced. About half way down the properties window
there is an option for "type of data to script". I select that and change it to "data only", then I finish the wizard.
All I do then is check the script, rearrange the inserts for constraints, and change the using at the top to run it against my target DB.
Then I right click on the target database and select new query, copy the script into it, and run it.
Done, Data migrated.
Since 2015, this can be done by use of elastic database queries also known as cross database queries.
I created and used this template, it copies 1.5 million rows in 20 minutes:
CREATE MASTER KEY ENCRYPTION BY PASSWORD = '<password>';
CREATE DATABASE SCOPED CREDENTIAL SQL_Credential
WITH IDENTITY = '<username>',
SECRET = '<password>';
CREATE EXTERNAL DATA SOURCE RemoteReferenceData
WITH
(
TYPE=RDBMS,
LOCATION='<server>.database.windows.net',
DATABASE_NAME='<db>',
CREDENTIAL= SQL_Credential
);
CREATE EXTERNAL TABLE [dbo].[source_table] (
[Id] BIGINT NOT NULL,
...
)
WITH
(
DATA_SOURCE = RemoteReferenceData
)
SELECT *
INTO target_table
FROM source_table
Unfortunately there is no way to do this in a single query.
The easiest way to accomplish it is to use "Data Sync" to copy the tables. The benefit of this is that it will also work between servers, and keep your tables in sync.
http://azure.microsoft.com/en-us/documentation/articles/sql-database-get-started-sql-data-sync/
In practise, I haven't had that great of an experience with "Data Sync" running in production, but its fine for once off jobs.
One issue with "Data Sync" is that it will create a large number of "sync" objects in your database, and deleting the actual "Data Sync" from the Azure portal may or may not clean them up. Follow the directions in this article to clean it all up manually:
https://msgooroo.com/GoorooTHINK/Article/15141/Removing-SQL-Azure-Sync-objects-manually/5215
SQL-Azure does not support USE statement and effectively no cross-db queries. So the above query is bound to fail.
If you want to copy/backup the db to another sql azure db you can use the "Same-server" copying or "Cross-Server" copying in SQL-Azure. Refer this msdn article
You could use a tool like SQL Data Compare from Red Gate Software that can move database contents from one place to another and fully supports SQL Azure. 14-day free trial should let you see if it can do what you need.
Full disclosure: I work for Red Gate Software
An old post, but another option is the Sql Azure Migration wizard
Use the following steps, there is no straight forward way to do so. But by some trick we can.
Step1 : Create another one table with the same structure of Suppliers table inside [AlexDB], Say it as SuppliersBackup
Step2 : Create table with the same structure of Suppliers table inside DesiredDB
Step3 : Enable Data Sync Between AlexDB..Suppliers and DesiredDB..Suppliers
Step4 : Truncate data from AlexDB..Suppliers
Step5 : Copy data from AlexDB..SuppliersBackup to AlexDB..Suppliers
Step6 : Now run the sync
Data Copied to DesiredDB.
If you have onprem version that has the sp_addlinkedsrvlogin, you can setup Linked Servers for both source and target database then you can run your insert into query.
See "SQL Server Support for Linked Server and Distributed Queries against Windows Azure SQL Database" in this blog: https://azure.microsoft.com/en-us/blog/announcing-updates-to-windows-azure-sql-database/
Ok, i think i found answer - no way. have to move data to client, or do some other tricks. Here a link to article with explanations: Limitations of SQL Azure: only one DB per connection
But any other ideas are welcome!
You can easily add a "Linked Server" from SQL Management Studio and then query on the fully qualified table name. No need for flat files or export tables. This method also works for on-prem to azure database and vice versa.
e.g.
select top 1 ColA, ColB from [AZURE01_<hidden>].<hidden>_UAT_RecoveryTestSrc.dbo.FooTable order by 1 desc
select top 1 ColA, ColB from [AZURE01_<hidden>].<hidden>_UAT_RecoveryTestTgt.dbo.FooTable order by 1 desc
A few options (rather workarounds):
Generate script with data
Use data sync in Azure
Use MS Access (import and then export), with many exclusions (like no GUID in Access)
Use 3-rd party tools like Red Gate.
Unfortunately no easy and built-in way to do that so far.
I would recommend SSMS SQL Server Import and Export feature. This feature supports multiple connection configurations and cross-server copy of selected tables. I have tried .NET Sql Server connector, which works very well for the Azure SQL databases.
I am using Oracle 9i, Please suggest how can I select data from one remote database and insert the data in the local database?
Also suggest how the data can be copied from a remote to remote database.
You need to create a database link.
Please refer to this link: http://download.oracle.com/docs/cd/B10501_01/server.920/a96521/ds_concepts.htm#12354
excerpts:
example:
CREATE DATABASE LINK sales.us.americas.acme_auto.com CONNECT TO scott IDENTIFIED BY tiger USING 'sales_us';
query:
For example, using a database link to database sales.division3.acme.com, a user or application can reference remote data as follows:
SELECT * FROM scott.emp#sales.division3.acme.com; # emp table in scott's schema
SELECT loc FROM scott.dept#sales.division3.acme.com;
Based on the vagueness of the question. Make a backup of production and restore it in development.
If you are talking Microsoft SQL then you can create a Linked Server. Here is an article about doing this in SQL 2008, but you can do it in earlier versions as well. Then you can select from it using a four part name LinkedServer.database.schema.table
http://msdn.microsoft.com/en-us/library/ff772782.aspx
Define a link from the development server to the prooduction server. You can then use a select based insert to copy data into the development server.
Use the SAMPLE clause on the select to retrieve a percentage of the data. For child tables use a WHERE exists clause to copy child rows for which the parent was sampled.
I am new to SQL and I am facing problems. When I create any table, I can't view it. Also, is it possible to enter the data into the table via management studio?
Like Harry 1234 xyz?
If you entered the query right, and it shows that the commands have been successfully executed, you should be able to see the created table with no entries by using select * from table_name.
If you still cannot see the data, try refreshing the database. Now you should be able to see your data.
Many database engines support entering data directly without SQL statements (like Harry 1234 xyz) like Microsoft SQL Server, MySql, etc. How you do it will depend on which database engine you're using.
You have to refresh "Object Explorer" in Management Studio.
It doesn't know that you created an object via SQL script
