I am using PHP to connect to endpoint to Virtuoso.
I have found SPARQL library and I have made some queries. The problem is that if I insert a huge string, Virtuoso doesn't allow me. When I do this query from Conductor, it is inserted. So I want to connect to database through sparqlib and insert my username and password. I haven't found anything like this. Is it possible?

I'm a newbie at cosmos db. and i'll be glad if someone help me to find how to catch queries that are going on local emulator. the reason why i'm asking is that now query string is appended in a few steps via linq and i need to be sure that query builder returns correct query string.
thanks in advance!
By the sound of it you are using the C# SDK and LINQ to query your database.
Once your LINQ query is ready you should be doing queryable.AsDocumentQuery() to generate a DocumentQuery object and the use that to do while(documentQuery.HasMoreResults) documentQuery.ExecuteNextAsync<yourtype>().
If that's not the case then you are using the SDK in an non optimal way.
All you need to do to get the generated SQL query is to do a .ToString() on the documentQuery object and you gonna get the translated query back.
In order to see the interactions between your application and Cosmos DB database, you can use Cosmos DB Profiler tool. It shows queries that are sent to Cosmos DB and stacktrace of relevant code that generated them.
The profiler shows statistics for each operation like duration, response status code, query execution metrics etc and also the request units for each request to a database what allows to optimize query costs.
It also alerts users about common pitfalls when using Cosmos DB and recommends how to resolve them.
Available reports provided by the profiler allow to analyze Cosmos DB usage by an application.
We have a database that we are connecting to via RODBC, the accounts have been given read only access on the database side, however if we log in via R we are able to read/write/execute. I have been using the read only command within the connection command as follows:
odbcConnect(dsn = "DSN",uid="un",pwd="pass",readOnly=T)
I've noticed that, while users cannot write to tables or write to new tables, they can create new tables. I would like to ensure that users are unable to modify the database to open this to a broader user group. Has anyone found a sure fire way to limit user access from the R side?
Per comments made by Gregor, the issue is not R side it is database side. The system that was being dealt with was performing security checks on a front end application rather than at the ODBC handshake. As such, R had no way of enforcing rules that were not enforced server side.
I am new to Progress. Previously I worked with Oracle, MSSQL and MYSQL. What is a great progress query tool, free or paid? I want to be able to write simple SQL queries.
In oracle i am using Toad,Pl/sql developer tool to connect oracle. Any thing in Progress 4gl?
Thank you
You can use any random SQL query tool that you like if the SQL engine has been exposed by the DBA. You just need login credentials and permissions just as you would for any SQL db.
Since you want to write SQL queries you should be looking for SQL access not 4GL tools. There is a very, very limited SQL subset embedded within the 4GL but that was created in the 80s and is little more than a marketing gimmick. For anything but trivial SQL you want to use the SQL-92 engine. Which means the DBA needs to have started a SQL broker, provided a port # for you and has granted appropriate permissions.
I am new to Oracle database and I wanted to create a database in Oracle. I followed this link to create a database:
http://www.fehily.com/books/createdb/createdb_oracle_11g_2.html
In Microsoft SQL Server, when we create a database, we use the create database command and the database creation is instantaneous [within fraction of seconds], but the Database Tool as described in link above took couple of minutes to create the database. Is database creation in Oracle this much slower?
Searching more about it, I have a feeling that this database created using above tool in Oracle is not equivalent to the database we create in SQL Server. Rather, the schema/user in oracle is appearing to be equivalent to database in SQL Server. Is it true?
So, If I want multiple databases in Oracle, do I create a single database and then multiple schemas inside that single database? And then are those multiple Schemas are my databases?
I am very much confused about all this. Can someone please refer me to a nice article/book that explains these things in oracle in detail?
For most purposes, yes you would indeed map a SQL server database to an Oracle schema (=user).
The term "database" in Oracle does not mean the same as in SQL Server. An Oracle "database" (from a technical point of view) is more like a SQL Server instance/installation, rather than a "database" in SQL Server.
SQL Server has two levels of namespace: database and schema. Whereas Oracle only has a single level of namespaces: a schema (which has a 1:1 relation to a user)
SQL Server and Oracle both support Schema.
A Schema is like a new database but it is not a new database
Maybe you are confused, Mysql doesn't support schemas but SQL server offers full support for it.
In mysql your database is a schema, to only difference is that it doesn't support multi schemas
For the part of creating multi databases or a single database if multiple schemas it all depend in your specific situation, you should test thinks like performance and how much money you want to spend, a multi database approach can be very expensive unlike a multi Schema approach
I've read in multiples websites that Azure doesn't support encryption.
However I'm migrating (more like a backup) an Azure DB to SQL Server using the "Azure SQL Migration Tool" and I'm getting a warning about scripting the views: "Encrypted objects will not be scripted".
Also found this note in their site: Problem fixed in v3.5.5. Basically, Stored Procedures, Views, UDF, Triggers ... any object that can be encrypted is check before hand. The objects that are encrypted are highlighted in yellow with red letters. On the summary page, a list of encrypted objects that will not be scripted will be displayed.
http://sqlazuremw.codeplex.com/workitem/5762
If Azure SQL supports encryption, how can I get the creation script for this view?
Windows Azure SQL Database (database-as-a-service) does not support encryption. However: If you run SQL Server in a Virtual Machine, you should have all features at your disposal, including encryption.
I can't explain what's happening with the migration from SQL Database to SQL Server, regarding creation scripts involving encrypted objects on the target side.
SQL Database still doesn't support encryption, so either you are reading from a SQL Server database, or there is a bug in the Wizard. There are no encrypted database objects in SQL Database as far as I know. If you are sure you are reading from SQL Database, just try creating an encrypted view in it and see what happens. From the MSDN documentation, creating an encrypted view is not supported: http://msdn.microsoft.com/en-us/library/windowsazure/ee336244.aspx.
I am curious to know if you are getting the same error with Enzo Cloud Backup: http://www.bluesyntax.net/backup20.aspx. Just use the free edition.
