Distribute Data Securely In SSExpress

Apr 20, 2006

I would like to distribute some data in SqlServer Express which only my application can read from.

My question is - is it possible to secure a database so that only a specified user would have read/write permissions. Even the sa acount should not have the permission to read or write to the database although it would retain the right to drop the database.

One option I believe is to encrypt the data but I would prefer not to incur the performance penalty associated with this.

Any insights would be appreciated.

Thanks

T-SQL (SS2K8) :: Distribute Data Into Groups Based On Existing Numbers?

Aug 11, 2014

i've been looking at moving one of our processed from excel (+vba) into t-sql to make life easier but am stuck.

We have lots of tasks that are assigned to work groups which we want to distribute evenly across the work groups. This is a simple task for ntile.. However when these tasks are no longer required they are removed which leaves the groups uneven. When new tasks are added we want to still try to keep these groups balanced.

EG Existing groups :

GroupName - Task Count
Group1 - 1000
Group2 - 999
Group3 - 998

If we were to add 6 new tasks they would have more assigned to Group 2 & 3 as they have less than group 1.

Task 1 - Group3
Task 2 - Group3
Task 3 -Group2
Task 4 - Group1
Task 5 - Group2
Task 6 - Group3
Sample tables
Create table GroupTable
(GroupID int, Name varchar(200) )
Insert into GroupTable values (1,'Group1')
Insert into GroupTable values (2,'Group2')
Insert into GroupTable values (3,'Group3')

Create table Jobs(jobid int identity(1,1), name varchar(100),Groupid int)

--Existing tasks

Insert into Jobs(name,Groupid) values ('Task1',1)
Insert into Jobs(name,Groupid) values ('Task2',1)
Insert into Jobs(name,Groupid) values ('Task3',1)
Insert into Jobs(name,Groupid) values ('Task4',1)
Insert into Jobs(name,Groupid) values ('Task5',2)
Insert into Jobs(name,Groupid) values ('Task6',2)
Insert into Jobs(name,Groupid) values ('Task6',2)
Insert into Jobs(name,Groupid) values ('Task7',3)

-- New tasks

Insert into Jobs(name) values ('TaskA')
Insert into Jobs(name) values ('TaskB')
Insert into Jobs(name) values ('TaskC')
Insert into Jobs(name) values ('TaskD')
Insert into Jobs(name) values ('TaskE')
Insert into Jobs(name) values ('TaskF')

This gives us 6 unassigned tasks and a uneven group assignment

GROUPNAME TASK_COUNT
<none> 6
Group1 4
Group2 3
Group3 2

This means the new tasks will be assigned like this

TaskA - Group3
TaskB - Group3
TaskC - Group2
TaskD - Group1
TaskE - Group2
TaskF - Group3

Embedded And Distribute MSDE On CD

Mar 18, 2004

Hi,

I am trying to find something like a light version of SQL Server 2k to store data for an application that will be distributed through a cd.

Since we also have a web front end for this application when the user is online, we prefer that we can reuse the code for connection on both the cd and the web.

Any idea what will work?

I have come accross MSDE 2k but was not able to find any documentation on the pros and cons for this product regarding its capacity, the type of data it can handle, security, ...

Please give me some pointer.

Thanks very much.

How Could I Distribute RS Load Among Multiple Cores?

Mar 17, 2007

Hi all,

We just bought a server with 2 quad core xeon processors to host a web application with reporting services.

Our reports are quite heavy. I wrote custom data processing extensions for them and some take up to 45 minutes to render.

When a web user runs more than one report at the same time, only one of the eight available cores is processing the request. When two different web users are each running a single report, the same thing happens. It looks like no matter how many reports are running at the same time, only one core chokes.

I would like to be able to execute each report request on a different core. How could a change my data processing extension or my Reporting Services settings to achieve that?

Any help would be appreciated,
Dom.

Data Reader Or Data Adapter With Data Set?

Dec 4, 2007

I have used both data readers and data adapters(with datasets) in the projects that I have worked on. I am trying to get some clarification on when I should be using which one. I think I am doing this correctly but I want to be sure I am developing good habits.

As the name might suggest, it seems like a datareader is for only reading data. I have read that the data adapter and dataset are for a disconnected architecture. Or, that they can be used for this type of set up. I have been using the data adapter and datasets when writing to a database and the datareader when reading from a database.

Is this how these should be used? Is the data reader the best choice for reading data? Am I doing this the optimal way from a performance stand point?

SQL Server Admin 2014 :: Change Data Capture(CDC) For Data Warehouse / Reporting?

Aug 12, 2015

I have a requirement to implement CDC for 50+ tables to implement incremental data changes warehouse/reporting rather than exporting the whole table data. The largest table is having more than half a billion records.

The warehouse use a daily copy of OLTP db (daily DB refresh). How can I accomplish this. Is there a downside in implementing CDC just for the sake of taking incremental changes on the tables?

Is there any performance impact if we enable CDC on OLTP db?

Can we make use of the CDC tables on the environment we do daily db refresh so that the queries don't hit OLTP database?

What is the best way to implement CDC to take incremental changes for reporting.

Data Conversion From String To Decimal When Saving Data To SQL Server 2005 Using An ADO Recordset

Feb 12, 2008

Hello,

I am wondering what conversion rules apply, when a string, which contains a number, is saved to a SQL Server 2005 into a column of type decimal.

This is the code I€™m using (C++):

CString cValue = "0.75"
_variant_t vtFieldValue;
vtFieldValue = _variant_t(cValue)
pRecordSet->Fields->Item["MyColumn"]->Value = vtFieldValue;

"pRecordSet" is an ADO recordset. The database column "MyColumn" is of type "decimal(19,10)".

The most important question for me is, if the regional settings of the database server or the regional settings of the client PC are considered during the conversion from the string to the decimal value. For example in standard French regional settings the "." would not be recognized as decimal separator.

I am also wondering if the language of the database instance, in which this data is saved, is considered during this conversion or any other settings of this database instance.

So my general question is: Does anybody know exactly what rules apply during the above mentioned conversion?

Thank you for your help.

Regards,
Volker

Power Pivot :: Structural Data Model Changes In Data Source Leads To Errors

Oct 12, 2015

I've question about how to handle structural datamodel changes in a datasource of PowerPivot. Suppose I'm developing a starmodel in SQL Server and sometimes a datatype changes or a name of a field changes in a table. It seems to me that PowerPivot handle this not gracefully as Analysis MD does (mostly). I received an error because of a wrong fieldname or even no error when a dattype changes in PowerPivot. Is this common or do I something wrong here. Does this mean that every time the datamodel changes the PowerPivot should be recreated? Or am I missing the clue here?

Data Flow Stuck In Phase The Final Commit Data Insertion Has Started

Jun 19, 2007

Hello,



I have noticed that for one of my data-flows, the process is really long during the phase "the final commit data insertion has started".

To be accurate, the process is fast until it reaches this phase. It happens often when I load millions of lines.



The extraction is done from a database SQL Server 2005 to a database SQL Server 2005, on the same server (with the SQL Server native provider).

I used a SQL Server destination but I have tried with an OLE DB destination and it is the same situation.



Why the process could be so long during this phase?

There is a way to optimised my package to avoid that?



Any idea is welcome.



Thanks.

Guillaume
