I am new to Oracle database. I have downloaded Oracle Database Express Edition 11g Release 2 and installed it on my laptop but when I open the database it opens command line. Is there any GUI software available? Please help me to get for the write one.
Oracle SQL Developer is a free graphical tool for database development. With SQL Developer, you can browse database objects, run SQL statements and SQL scripts, and edit and debug PL/SQL statements.

I have followed the instructions for setting up a new ODBC connection to CosmosDB. I would like to use this ODBC connection in an SSAS tabular project but I don't see a way to do that. I am on SSDT 15.1. When I click the "Others" data source for OLEDB/ODBC in SSAS, it only gives me build options for OLEDB. It's not clear how I would use this to connect to my CosmosDB ODBC.
Has anyone figured out how to do this? According to Microsoft it is possible but they have no instructions for it.
It is possible. Launch the "ODBC Data Sources (32-bit)" app and setup a system DSN as described in this article. Then open "ODBC Data Sources (64-bit)" and setup a system DSN with the exact same name as the 32-bit DSN. The reason is that Visual Studio is 32-bit so when performing some steps it requires a 32-bit driver, but once SSAS loads the table into memory that occurs in a 64-bit process which requires the 64-bit driver. Setup these DSNs on your workstation and on the workspace server (local if using the integrated workspace or on a dev server if using a remote workspace).
Using ODBC drivers inside Analysis Services Tabular doesn't seem to be very well documented. Basically you need to use the OLEDB for ODBC driver.
When creating a new connection in Visual Studio in your SSAS model, instead of choosing the driver from the dropdown, just type in the following connection string:
Provider=MSDASQL;DSN=YourDsnNameHere
If you prefer inline connection strings that make deploying easier to do without ODBC DSNs then you can use this connection string:
Provider=MSDASQL;DRIVER={Microsoft DocumentDB ODBC Driver};Host="https://yourcosmosdbname.documents.azure.com:443/";AuthenticationKey="authKeyHere!";LocalSchemaFile="c:\folder\yourCosmosSchema.json";KeyEncrypted=true;NumberOfRetries=5;DSNType=0;Consistency=1
Regardless of which connection string you will probably have to write a query such as select * from CollectionName rather than picking from the table list.
If you are using 1400 compatibility level models (Analysis Services 2017 or Azure Analysis Services) then you should consider using the modern get data experience which has native Cosmos DB integration that's a lot more polished.
I have been tasked with building an application for a Windows laptop that engineers can take out into the field where there is no internet access. Then, they will add data through a form and once they get back and have internet access, they can then hit a "Sync" button and send the data they collected to an external SQL Server database.
The database is SQL Server 2016 and the application is going to be a C# .NET desktop application. My question is what options are available for the database when there is no internet access? I don't really want to do Excel or Access. I really like SQL Server Compact but it seems dated. Is SQL Server Compact still relevant with the latest .NET Framework or is there something newer that everyone uses?
You could try creating a ssis package that syncs data between the offline database and live database.
The ssis package can be executed either as a sql server job that runs at intervals
or
from a stored procedure . Please find the below link on how to execute a package from stored procedure.

The stored procedure can then be called from inside the application.
I was working with Oracle 11g and now I wish to migrate into Microsoft SQL Server 2008 for academic learning purposes. I have my DDL in a .txt file with all the syntax compatible with Oracle. Now I have to create the same tables and insertions in SQL Server. What are the possible options to convert or import my existing database created in Oracle to SQL Server ?
Take a look at this link
http://technet.microsoft.com/en-us/library/hh313159.aspx
It describes step by step the procedure of migrating ORACLE database to Microsoft Sql Server database.
To Convert Oracle 11g to SQL Server 2012, Microsoft provides a tool called SQL Server Migration Assistant for Oracle (SSMA).
Below are very high level steps:
Download SSMA for Oracle from this Link. Make sure you have
downloaded SSMA for Oracle and SSMA for Oracle Ext Pack. Install one
after another.
Note: At the time of installation, it will give option for DB
Instance and also for creation of Master password. Keep a note of
them. You might need them later.
Open SSMA and create a new project.
Connect to Oracle DB.
Connect to SQL Server 2012.
Convert schema of Oracle.
Migrate data of Oracle.
Synchronize with SQL Server.
Youtube link for a straight forward conversion.
MSDN PDF link for Datatype and other extensive information on the conversion.
The above is only to get you started, even I am not sure about few options like Sequence and DBLinks. Good Luck.
My course requires me to connect to an Oracle database server at the university for my project. I am provided with a url (like oracle.xyz.edu) and username and password. How can I connect to the database from Visual Studio. I have only dealt with SQL Server 2008. I don't know how to go ahead with setting up the database. I tried to install Oracle Instant Client, but could not find a setup exe to install. The instant client download zip consists of a set of files. Where can I find the steps to connect to Oracle database from VS.
Do you need to use the Oracle Instant Client? Or would it be acceptable to you to download and install the full version of the Oracle client?
The full version of the Oracle client is generally what ought to be installed on a developer machine. The Instant Client is a very slimmed down version of the client that is designed for developers to distribute along with their Windows applications on machines that do not have or need any way to access the database other than via the application. As a developer, I'd strongly recommend the full version of the Oracle client if only because it includes various additional utilities like SQL*Plus and SQL*Loader.
The full Oracle client is available for download from OTN on the same page that the database is available. For example, the Oracle 11.2 client for 64-bit Windows is a 615 MB download on the OTN site.
Don't use ODBC. Use ODP.NET (Oracle's Instant Client) Oracle Data Provider for .NET. (Read technical notes in provided link.)
I come from a linux/apache/php/mysql background. For my current project, I am forced to write web services using ASP.NET. I have installed visual studio and created an ASP.NET web service project. The web service I'm creating will use a SQL database backend. I see that visual studio installed "SQL Server Express 2008." I can see that there is a service called "SQL Server (SQLEXPRESS)" that is running. My question is, how do I run queries against this database? Where's the front end? What tool do I use to create databases and tables? Is there something else I have to install?
I feel completely lost and my google-fu fails me. There are so many different SQL products from microsoft that I can't tell what is the easiest path to just having a simple database with tables I can query from my development machine. With MySQL, I would install the MySQL database, download MySQL query browser and start firing queries at it. How can I do that with Visual Studio/SQL Server Express?
You can download SQL Server Management Studio from here. This is the GUI for working with SQL Server. It will let you create databases, tables, stored procedures, etc. as well as writing queries and manually edit data in the tables.
Aside from SQL Server Management Studio, you can use the Server Explorer tab in Visual Studio (by default on the right side, next to Solution Explorer) to add a data connection. You can do most of the most common database tasks (create/query tables, create views, etc) from there.
there's a command line tool that installs with SQL Server (all versions) called SQLCMD.exe, should be in your install path.
Visual Studio also lets you create dbs, run queries, look at table structures and data (including creating and deleting them, etc), you do that by opening your Server explorer window and making a connection to your local instance (.\SQLExpress by default).
Finally, as the other person mentioned, SQL Server Management Studio Express is a free download, and well worth the time it takes to install.
