I think this will work if the number u require is always
1 less than the max number.
Here is the command for the column which have random values.
select max(colName) From tblName where
colName not in( select Max(colName)From tblName)

Both result sets from the stored procedure will be present in the dataset - That is why it has a collection of Tables.

Hi All
I am writing an app that is a time tracking systray utility but the scope has grown. The Version 1 release used a local Access DB to store Data but now management want to sync it centrally to an SQL server so group wide reports can be pulled.
In short I am looking for direction on the best way to tackle this.
SQL Sample Table
CustomerID (int) Identity = Y (i.e. Auto incrementing)
CustomerName (Text 50)
DeleteFlag (int)
RecordTimeStamp (timestamp)
MS Access
CustomerID (int) I Get the SQL ID for the record and put here)
CustomerName (Text 50)
DeleteFlag (int)
My first thought (well within the first 10) was to check the SQL timestamp and only add records that were newer that the last stored timestamp.
Thoughts

At that point why even use the Access database at all?

Don’t forget to add a developerID to that list, wont be long and management will want to know who’s working on which projects.

Hi All,
I am newbie for .net. I have created the simple console application and trying to create connection to SQL database.
Here is my code for console app:
<br />
#include "stdafx.h"<br />
#include "vcclr.h"<br />
#include "atlstr.h"<br />
#using "mscorlib.dll"<br />
#using "System.dll"<br />
#using "System.Data.dll"<br />
<br />
using namespace System;<br />
using namespace System::Data;<br />
using namespace System::Data::SqlClient;<br />
<br />
int _tmain(int argc, _TCHAR* argv[])<br />
{<br />
CString hello("Hello");<br />
gcroot<SqlConnection ^> m_SqlDbConnection = gcnew SqlConnection(gcnew String(hello)); <br />
return 0;<br />
}<br />
I have the following exeption
An unhandled exception of type 'System.ArgumentException' occurred in System.Data.dll
Additional information: Format of the initialization string does not conform to specification starting at index 0.
on the string
gcroot<SqlConnection ^> m_SqlDbConnection = gcnew SqlConnection(gcnew String(hello));
Please help me to resolve the problem or point me to the article.
P.S. I found that CString defined as in the atlstr.h
typedef CStringT< TCHAR, StrTraitATL< TCHAR, ChTraitsCRT< TCHAR > > > CAtlString;<br />
typedef CAtlString CString; Maybe it helps.

It failed because the connection string you provided it, "Hello", isn't a valid description of what kind and which database you want to connect to. You might want to have a look at ConnectionStrings.com[^] for many examples of what connection strings for various databases are supposed to look like.
My C++ is really rusty, but it loks like you need to back away from the database stuff for now and start by learning the basics of CLI before you jump into the deeper end of the .NET Pool.

We can Build our DATABASE, I just wanted to know a brief about this ,Though not to create but to have general Idea about it.

I don't understand what you mean by "Build" a database as opposed to "create" a database?
|
|
|
|
|
Ok , Sorry for ambiguity.
what I mean here is: we can develop our own datsbase same like that of MS Access

If you want. I don't, personally, see the need as many highly skilled people who are well versed in the theory and implementation of database systems created things like MS Access, SQL Server and the like. Microsoft spends billions of dollars on creating those pieces of software and I'm sufficiently aware of my own abilities to realise that I could no where near match what they do.

You want to build your own database server ? Or, you want to build your own front end generator for databases from a variety of sources ?
This belongs in teh C++ section, I can't imagine doing it in any other language, and SQL and ADO are not going to help you.

Well, VistaDB was written in C# so it isn't impossible.
Also, when he writes his database software he'll most likely want to be able to access it in a .NET application so he's going to have to write a provider for it.

No, but probably stupid, if he wants it to perform and scale as well as Access or SS ( not that they scale as well as each other )

That's what C++/CLI is for.

Well, if you just want to know how it is done, why not look at the source for some open source databases. Do a search for SQLite or MySQL. If you want to be more esoteric and go for an object oriented database then search for db4o.

Have you thought of doing an internet search for it: MySQL Source Code[^]
The search results above will give you links to documentation of the Source Code as well as the source code itself.

SELECT MIN(BankID) AS DBComboValue, (BankSortCode) As DBComboText, BankName, BankAddress3<br />

Return @@RowCount
I have the following code to retrieve a count of rows in a result set. It works but I don't want the result set to be returned. All I want is the RowCount. My original approach was to use COUNT in the main query but I couldn't seem to get this working due to the grouping I perform. Therefore I decided to use @@RowCount and hence my current problem.
Thanks in advance.

Remove all the items from the SELECT list and replace with COUNT(*). Remove the ORDER BY clause.
If the grouping causes a problem, do it as a subquery
SELECT COUNT(*) FROM (SELECT ... )
You can then access the value using ExecuteScalar from your application.
