In Azure Data Studio one can download extension of multiple SQL clients and run SQL Queries, but wanted to check if in latest version of SSMS if we can do same things. Reason being one has to deal with multiple clients for running queries across multiple databases.

I've recently joined a company with a mixed set of databases that include a Redshift cluster and some SQL databases. I'd like to use a single IDE to access both for analytical reporting, so I don't have to switch between tools. I'm currently using workbench, which works, but it's not clicking with me.
I do like Azure Data Studio, but it's SQL Server and Postgres only. Given the similarities between Redshift and Postgres, I thought I'd see if I could connect using the Postgres driver.
I've installed the Postgres extension and can "connect" to the database. However when I try to explore the database using the tree view, I get the error message 'Cannot Expand Node'. When I run a simple query that works in workbench, e.g.
Select * from [server].[database].[table]
I get the following Error message:
Started executing query at Line 1
cursors can only be used within the transaction that created them.
Total execution time: 00:00:00.019
I know I'm trying to do something that shouldn't be done. And if I can't, I can't. But has anyone here managed to get a redshift connection going in Azure Data Studio?
FWIW, I've come across a GitHub Repository that may be a Redshift driver for data studio - but this looks like a clone of the Postgres driver, with no activity since march (not even renaming the 'Postgres' titles to Redshift)... and therefore I'm dubious.
As the title says, I need to restore a SQL Server 2012 database (express) to a SQL Server 2008 R2 production database.
I cannot find a way to do so.
The scripting seems to fail due to the size of one of the tables having about 300.000 records.
Any way to "downgrade" the 2012 database?
Thanks
Michael
You CANNOT do this - you cannot attach/detach or backup/restore a database from a newer version of SQL Server (2012) down to an older version (2008 R2) - the internal file structures are just too different to support backwards compatibility. There's no way, no trick, no hack, no magic to make this happen. Period.
You can either get around this problem by
using the same version of SQL Server on all your machines - then you can easily backup/restore databases between instances
otherwise you can create the database scripts for both structure (tables, view, stored procedures etc.) and for contents (the actual data contained in the tables) either in SQL Server Management Studio (Tasks > Generate Scripts) or using a third-party tool
or you can use a third-party tool like Red-Gate's SQL Compare and SQL Data Compare to do "diffing" between your source and target, generate update scripts from those differences, and then execute those scripts on the target platform; this works across different SQL Server versions.
I know the basic syntax of queries but otherwise I'm a beginner with SQL.
I have an SQL file (.sql) and I downloaded a couple programs (pgadmin and sql workbench).
I have no idea how to get from where I am now to actually writing queries and finding information. How do I set up so I can actually import my SQL file and start writing queries?
pgAdmin is the default GUI for PostgreSQL.
SQL Workbench is a free, DBMS-independent, cross-platform SQL query tool.
Either way, you need to connect to a database to actually run queries. The DBMS can either run on your local machine or you can connect to a remote server - where you need access privileges of course.
I'm having trouble running sql commands to my database on Windows Azure. Previously I had no problems at all running my commands and stored procedures with SQL management studio until I added another database on the same server. I can still connect and even se all the tables and both databases i SQL management studio but I cannot run any commands.
If I use the online management portal I am able to run my SQL but not with SQL management studio.
select * from nextlabel.[Article]
and it gives the folowing error:
Invalid object name 'nextlabel.Article'.
Any ideas on how to connect properly to one of the databases or if I'm doing something else wrong?
Suppose I have multiple Oracle databases in the same server. Now I want to connect to particular database and query a table just like SQL Server 2008. How to start particular Oracle database?
If you are using SQL*Plus, the most common syntax for opening a connection is
sqlplus user_name/password#tns_alias
In this example TNS_ALIAS is the TNS alias for the particular database you want to connect to (most likely "XE" based on your followups to inium's answer). If you want to connect to a different database, you would need to specify a TNS alias for that specific database.
Note that since you are coming from a SQL Server background, the SQL Server definition of a database is rather different than the Oracle definition. What SQL Server calls a database is similar logically to what Oracle calls a schema (and similar physically to what Oracle calls a tablespace). So when you're dealing with Oracle, it's much more common to have many schemas in a single database than to have a large number of databases on a server. This is particularly true if you're using the Express Edition (Oracle XE) where you're generally limited to one database per machine.
go to cmd and type sqlplus <database-name>/<database-password>
You can use SQL Developer, it's similar to SQL Enterprise Manager 2005. Just create a new connection using the db user name and password.
