Why? This will be inefficient when there are native drivers available. Why not take a look at the Factory pattern that MS used with .NET 2? This allows you to work in a reasonably database agnostic fashion. Take a look at the classes DbConnection and DbCommand in System.Data.Common to get an idea as to how it all works.
Deja View - the feeling that you've seen this post before.

Also, look up dataprovider factory on msdn. This will give you some good info.

Hi,
I am getting the exception " Procedure or function SummerizeInsert has too many arguments specified." But so far my coding is correct. also i noticed this error comes when the loop is going through for the second time.

Would you care to show the code so that we can verify this?

It appears your insert command exists prior to the loop. The loop adds the necessary parameters. On the second iteration it adds the parameters again to the command. So there are now two sets of parameters in the command. (Hence the too many parameters exception)
You need to either
* setup the parameters once (before the loop) and assign the values only on each loop.
Or
* remove all the parameters in the command at the start of the loop.

It seems, the connection is not closed, so you are passing into stored procedure
number of ther required parameters multpileid by number of rows in your DataTable.
I am not sure, this was your intend

AS THE ERROR INDICATES YOU HAVE PASSED MORE VALUES TO THE PROCEDURE/FUNCTION THAN REQUIRED.

This means, you haven't closed the connection to your db server. So, you are passing the parameters twice!

mysql has limit to show limited rows
but how what does mssql have?
i want to make a paging like code
i have stumbled on this code
select tag, difference from (
select top 4 * from (
select top 8 *
from flexi_pump
order by tag asc
) as newtbl order by tag desc
) as newtbl2 order by tag asc
it works great, but what if the last page only has one row. this sql query shows the last four, not only the last one. (my table has 9 rows)

Hi All,
I want to know how to insert multiple rows
in SQL Server 2005.
Please anybody can help me.
|
|
|
|
|
Some ideas:
* Call INSERT multiple times
* Call INSERT with a SELECT that returns multiple rows.
|
|
|
|
|
how can i remove duplicate row in any table.
i have no column having constraint.
so how can i do it.
how can i find number of diplicate rows in any table.
|
|
|
|
|
Are all your values of your rows the same or just a special collum?
I think it might work with:
delete from TableName t1 where collum = (select colum from TableName t2 where t1.Value = t2.Value)
;
I am not quiet sure if this work, but it might.
I hope I could help you 
See you
|
|
|
|
|
i use one table.in that many row having equal values in all column.i want anly first row of duplicate rows and other rows deleted.
|
|
|
|
|
In this case you might have to write t1.Value = t2.Value and t1.Value2 = t2.Value2 and ...
depend on how many collums you have. I hope it work coudn´t test it. But I think it will do.
