YTD Concept

Apr 15, 2008

Hi Friends,
Can anybody help in introducing the YTD Concept:

My Table[ Monthly_Highlights_tb ] schema should contain like below:
[Month] [Base_Amount] [YTD]
APR-07 1000.00 1500.00
APR-07 500.00 1500.00
MAY-07 2000.00 3500.00
jUN-07 5000.00 8500.00

WHEN I run the below query:

UPDATE t
SET t.ytd = (SELECT SUM(q.base_amount) FROM Monthly_Highlights_tb q WHERE q.[month] = t.[month] AND q.[month] <= t.[month])
FROM Monthly_Highlights_tb t

output is coming as:
[Month] [Base_Amount] [YTD]
APR-07 1000.00 1500.00
APR-07 500.00 1500.00
MAY-07 2000.00 2000.00
jUN-07 5000.00 5000.00

cAN anybody correct the query?

Basic Concept Clarification

The distinction between Entity and Relationship is obvious to me. But I am confused by Table. Table describes Entity, Relationship, or both?

Thanks for any input.

Nested Table Concept In SQL Server

May 8, 2004

Hi all,

What is the equivalent for Oracle's nested table concept in SQL Server ?
Is there anything like TABLE( ) function to select from nested table as in Oracle ?

Eg in Oracle :

SELECT t.* FROM TABLE(nested_table_datatype) t;

( like the above query used in Oracle PL/SQL and 'nested_table_datatype' is a table datatype created in Oracle using 'create type ...' syntax )

Please give the equivalent for above...

Thanks,
Sam

How Can I Dynamically Build Sql SELECT Using ASP 1.0 Array Concept

Jun 6, 2007

The below code is ASP 1.0 to dynamically search a database and I want to use the same concept for a ASP.Net 2.0 solution.  Do I do this in the code behind or on the aspx page and if on the aspx page what controls do I use for the array split?  Basically where do I start.  It took me a long time to get this old code working, I am hoping it is simpler in 2.0.
Thank you
OLD ASP 1.0 code to dynamically build a Sql Select statement for searching a database using one or more search words entered by user.
If Request.Querystring("kwdSearch") <> "" ThenDim kwdString, ArrKwdString, iCountiCount = 0 kwdString = Replace(Request.Querystring("kwdSearch"), "'", "''")ArrKwdString = Trim(kwdString)ArrKwdString = Split(kwdString, " ",-1,1) For iCount = 0 to UBound(ArrKwdString) If iCount < UBound(ArrKwdString) Then  Criteria = Criteria & "tblLinkInfo.L_Keywords LIKE '%" & ArrKwdString(iCount) & "%' AND "  Else  Criteria = Criteria & "tblLinkInfo.L_Keywords LIKE '%" & ArrKwdString(iCount) & "%' " End ifNext    RS.Open "SELECT * FROM tblLinkInfo Where (" & Criteria & ") AND L_Enabled = 1 ORDER BY " & SortBy & "L_Rank", CNN, 3 If RS.EOF Then  If Rs.State Then RS.Close  RS.Open "SELECT * FROM tblLinkInfo WHERE L_Description LIKE '%" & Replace(Request.Querystring("kwdSearch"),"''","'") & "%' AND  L_Enabled = 1  ORDER BY " & SortBy & "L_Rank", CNN, 3  End If
  RESULTS --- Display results with Repeater1.DataBind(); etc
  Exit SubEnd If

Enterprise Product Develepment (concept To Rollout)

Apr 2, 2004

Hi

I am involved in a product development and want to understand the current best practices from the conception to product rollout. I have few questions. Appreciate your help and suggestions

Our project in a nutshell: Our team has developed the apps. using GUI-Oracle Forms & DBMS-Oracle 8i/9i with weblogic, Corba, windows 2000 server environment. It’s meant for 1000s of users with million of data. We are trying to integrate additional services/capability - messaging (wireless, chat etc.). As per the initial plan we have a central database and users will be using a local footprint database. The deltas (the changes) will be synchronized with the central database at a frequency say daily or nightly... We are concerned that having the database at the users desktop could leave the door wide-open for others to take a look at our code/design...

Questions:

1. UML case tools-- What’s the best tool available in the market as we want to revisit the design phase and identify the things that have been missed out in the prototype-(which was developed by a third-party)?
So far we have used ERWIN to extract the data model...

2. How can we eliminate the need to have a local footprint database at the users desktop.?. Since there is a lots of data, retrieving the data via internet could be very slow for users? (hope this is the case!) That’s what led our team to think of having a local database at the users desktop. Someone suggested to use the data files or caching the data.. Appreciate if anyone shed some light on this.. Is there a better way to do it?

3. Client connectivity: What are the softwares needed at the users PC. Since we use Oracle Forms to develop the application, do we need to install the oracle clients at the users PCs? how to establish the connectivity from the Users PC to our server and to the database. IF we have to use the oracle client, does that require licenses for every User? What do we need to consider from the network connectivity stand point.

4. Application Rollout: how to package our finished product - application exe that is installable across wide array of environment. (we thought of install shield). how do we test it for accuracy etc.,

5. Database optimization: In addition to DBA help, is there any product or proceedures to ensure dataModel optimization, SQL query performance etc.,

Appreciate you sharing your valuable thoughts on this with us..

DB Design :: Can Use Another Server / Disk To Store Files Using FileTable Concept?

May 11, 2015

I tried samples of FileTable in SQL Server 2012 to store files in database. I have following questions.

1. When I right click on FileTable, and say Explore File Table Directory, I was taken to a directory. But if I search the same directory in my server/machine, the directory is not available.

2. Can I use some external server/disk as a directory for FileTable?

3. How easy is to use FileTables using .Net web applications?
