Does running the stored procedures slow down the user's login at all? In other words, does the stored procedure have to finish before the asp continues? Or can I just trigger the stored procedure and then continue on with login and browsing, from the script perspective. I have done only limited stored procedure work, so fogive me if I am being dense.
I assume the db server would happily go off and run the stored proc while the user continued with his session, but I am unsure. If the user can continue browsing the site after logging in without any percieved delay, then this would seem to be the solution I am looking for.
Thanks

Hi
Does running the stored procedures slow down the user's login at all?
In my case, no - it will depend on how many users you have and if your table is properly indexed. You can run some tests against your db to check how long does it take. Remember: the SP will run only once a day. Even if there's a little delay, it will be just for the first user of the day (and it could be you, if you wake up early  )
does the stored procedure have to finish before the asp continues?
I would say yes, because you may check your data against an out of date table, in case the SP is still running in background.

Wanderley

Thanks for the help!
You gave me a couple of ideas I hadn't thought of before. That was what I needed, some fresh angles on the problem.
I wanted to do the check on session start, but I didn't want to slow down all the logins too much. It totally hadn't occured to me to flag myself with a file so it didn't always run. (Slaps self on forehead  ) Sometimes you just get too involved in a problem and forget the simple solutions.
That coupled with moving the code into an SP should do the trick nicely.
Thanks again,
Jason Jystad

What is the most efficient method of identifying duplicate records in my database? The duplication is likely to be in more than one field but within the same table. I don't want to enforce non-duplication using a primary key as the duplicates won't neccessarily need to be removed.
I thought of building up a list of the unique entries and then comparing each record against this but it seems like it would take an awful long time.
Cheers

Hi
Imagine you have a table with 2 fields (name and age):
1. To find duplicate names, use SELECT [name], COUNT(*) AS TOTAL FROM [table] GROUP BY [name] HAVING COUNT(*)>1
2. If you need to check both fields, just add [age] in SELECT and GROUP BY.
HTH
Regards,
Wanderley
ps: COUNT(*) will give you the number of times your field is duplicated

Thanks for your response - it's a great help.
How would I adjust the query to print out the duplicate records in grouped by the duplicate names ie
Name Age Shoe Size
Tom 12 6
Tom 12 7
Tom 12 8
Steve 26 12
Steve 26 13
(Excessive amount of sample data, I know)
Cheers

Hi
Do you want just a list of unique names or you need to know the duplicated ones? From your example:
Name Age Shoe Size
Tom 12 6
Tom 12 7
Tom 12 8
Steve 26 12
Steve 26 13
John 12 9
Do you want Tom, Steve and John (without duplicates) or Tom and Steve?
Regards,
Wanderley

Hi Wanderley - thanks for the help so far,
I want to find all the records which are duplicated. Those which are duplicated, I want to be able to list each of the duplicated records giving the user the option to pick which one is the correct one. All the records for which there is only one entry should not be displayed. Does this make sense?
So I want to display the information as displayed above. The database would probably also contain many records which were not duplicated which have not been displayed.
Can this be done?

Hi
Assuming that you're checking for duplicated names, you could do something like this:
1. Create a combobox and fill it with all duplicated names using SELECT [Name] FROM [your table] GROUP BY [Name] HAVING COUNT(*)>1
2. Create a listbox (or listview) and fill it with all records that match with the name selected on combobox using SELECT * FROM [your table] WHERE [Name] = 'selected name on combo'
This way, you'll have all duplicated names on the combobox - whenever you select a name, you can clear and fill the listbox and select the correct one.
Is it too confusing? 
Please let me know if you still have problems.
Regards,
Wanderley

Thanks again Wanderley.
I understand what you said and it's pretty much what I thought in the first place. Thanks for your help.

Does anybody know, if it is possible to create a new dBase file using ADO? During my tests I had to learn that my provider does not support creation of this file. Is there any other provider? Sample code below:
Using the connection string to create an Access-file is no problem (see strcnn).
Thanks.
#include "stdafx.h"
#import "c:\winnt\system32\dllcache\\msadox.dll" no_namespace
#import "c:\winnt\system32\dllcache\\msado15.dll"
#include "iostream.h"
#include "stdio.h"
#include "conio.h"
void CreateDatabaseX(void);
int main(int argc, char* argv[])
{
printf("Start...\n");
HRESULT hr = S_OK;
hr = ::CoInitialize(NULL);
if(SUCCEEDED(hr))
{
CreateDatabaseX();
printf("\nPress any key to continue...");
getch();
::CoUninitialize();
}
return 0;
}
void CreateDatabaseX()
{
HRESULT hr = S_OK;
_CatalogPtr m_pCatalog = NULL;
//Set ActiveConnection of Catalog to this string
//_bstr_t strcnn("Provider=Microsoft.JET.OLEDB.4.0;"
// "Data source = c:\\Projekte_test\\create\\new.mdb");
_bstr_t strcnn("DSN=dBASE-files");
try
{
hr = m_pCatalog.CreateInstance(__uuidof (Catalog));
m_pCatalog->Create(strcnn);
}
catch(_com_error &e)
{
// Notify the user of errors if any.
_bstr_t bstrSource(e.Source());
_bstr_t bstrDescription(e.Description());
printf("\nSource\t\t: %s \nDescription\t: %s \n ",(LPCSTR)bstrSource,(LPCSTR)bstrDescription);
}
catch(...)
{
cout << "Error occured in include files...."<< endl;
}
}

I Suggest that you try and find a OLE DB provider for dbase or (xbase) before attempting to do this.
You are trying to execute functionality for dbase with the Access OLE DB provider.
There are various third parties that sell OLE DB Provider for xbase.

Hello!
You need to tell the Jet engine that you're using 'dBase 5.0' then you also need to install Borland BDE otherwise you will only be able to use the database in read-only.
I always use an .udl file to specify the connection (no change of the program if I need to change database).
Hope this will help!
// Mike
PS! I have not tried to create a dBase database only reading and writing to existing databases.

Hi,
I, also, am tasked with creating new dBase files using C# in the Visual Studio .NET and ADO .NET.
If you got yours working, would you please share your steps and solution with me, by email?
Thanks, Don.

Hi,
I'm Using an SQL statement "Select * from User_info order by user_name" i am getting the results in ascending order the problem is the Null values are arriving at the last when i want then to be first in acsending order the same applies with descending the appear first when i want them last can any one help me out with this\
Thanks in Advances ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

You could filter the NULL valued records out and make this into a two stepped process
e.g. first select all the NULL values
Select * from user_info where user_name IS NULL
then
Select * from user_info where user_name IS NOT NULL order by user_name

Hi,
I am using db fetch for accessing data from the database, in bulk, but when my table has more than
255 columns, bulk fetch neglects the remaining columns abnd fetched only 255 of them. please advice.

I want to handle the WillChangeField event in my RecordsetEventsVt derived class
One of the parameters is a VARIANT FIelds that is a SAFEARRAY.
I verify that it is a VT_ARRAY | VT_DISPATCH variant, and the parray if well filled.
But when I try to find an element whith the COleSafeArray::GetElement, the resulting variant is nothing.
Is somebody can tell me hown to trap the FieldPtr inside the SAFEARRAY Fields parameters?

(C++!)I tryed to insert some data into Excel table with use of Excel type librarys and figured out it is slow as hell. Then i tryed to find out some
other solution and started to play with ODBC. I opened ADOX::_CatalogPtr to Excel file and tryed to insert new table; it didnt work! Then i have tryed some other methods like SQL (CREATE TABLE...) on that connection and everything failed! Same happened when i tryed to create new column in same table with ->Append(...) and SQL method and allso both failed. Same was with inserting data into existing column...
Anyone knows how to insert some data there trough ODBC???

Hi all.
Does anyone ever encounter a skipping recordset in DTS via active-x script?
My situation is like this, I am running a dts process which uses a recordset to retrieve each record in a table (using recordset object), then pass some of the values into a ADO command object to execute a stored procedure with the parameters from the record that I retrieved. I keep doing this until the recordset hits EOF. If the process is successful, I would delete the record via adoRec.Delete 1 (adoRec is my record set object) then do adoRec.Update. Then I do a move next to retrieve the next record in the table. However, sometimes the record set does not go through each record in the table but it skips some records. The problem would gone after I restart the SQL server (version 7).
Anyone know what is the cause and solution for this problem?

(Beginner to SQL/MSSQL).
I have created some SQL scripts (e.g. for repopulating tables for test), and saved them to external file (e.g. repopulating tables). I want to get SQL server to execute the scripts. I do *not* want to use an interactive utility (e.g. Query Analyzer, though that's where I generated and saved the scripts), nor a command-line utility (e.g. osql, though it does precisely what I'm trying to do). I do not want to store them as stored procs in a db. I want to do it from code (actually C# & ASP.NET application, though that shouldn't matter).
The files are accessible to the SQL server. What I want is a SQL statement like:
EXEC <file-path>
but I can't find anything like this. Yes, I could write code to open the file and append all the text to a string I finally submit to an ExecuteNonQuery(), but this seems brain-damaged to me (is this in fact what osql does?).
*Surely* there's something for this?
TIA

Does anybody have experience in updating dBase files using ADO. In my simple project I allways receive an error telling me that I do not have the right to update while using pRecordSet->UpdateBatch(adAffectAll).
Thanks

Update MDAC and you can update dBase files.
