I've started using Enterprise Library and have the following questions:1)How do I add output parameter to this query and how do I get it back:
public int InsertDoc(HDocument document)
{
Database db = DatabaseFactory.CreateDatabase();
int result;
var reader = db.ExecuteNonQuery("sp_InsertDocument",
document.AddedDate,document.AddedBy, document.Title))
.
.
.
}
The db.AddOutParameter requires paremetrers that I don't have like DbCommand.2)I have a few methods that work with database (I transfer from ADO.net) stored procedures, do I have to declare : Database db = DatabaseFactory.CreateDatabase(); in each one of them or I can reuse it?
instead of returning my output paremeter value in my stored procedure to my label it returns the default value i set my output parameter to. why cant i put my output parameter into my text label
Dim reader As SqlDataReader cmd.Parameters.AddWithValue("@tour", "2365") cmd.Parameters.Add("@tourname", SqlDbType.VarChar) cmd.Parameters("@tourname").Direction = ParameterDirection.Output
The problem is that, how to return OUTPT value to dTtoal and the remaining. Because now it's show assigned values as 1, 2, 3, 4 resp. I mean the bold values.But, if I execute SP using EXEC then it works fine, shows result correctly.
I have a stored procedure with output parameter. I encapsulate it with Table Adapter and BLL. Call it using ObjectDataSource in conjuction with formview, just like the one in Data Access Tutorial. How do I get the output parameter in event INSERTED of the ObjectDataSource in code behind (VB)?
We have a stored procedure which creates and returns as output the next value in line:
[Code]....
Yes, the dullards who created this system not only failed to use an identity for the primary key of this table, they then proceeded to add 1 to a varchar column to create the new value, thus insuring it can never be anything but numeric.
Sigh. I'm told we cannot address that obvious deficiency now, and we have to leave the column as varchar. Double sigh.
If I execute this sproc from SSMS, the hh_num variable is returned as expected:
[Code]....
However, when I run it through the application, the parameter I set up as output does not get its Value attribute changed:
[Code]....
I've verified that the "@hh_num" maintains its direction and name through the ExecuteNonQuery call, but its Value remains an empty string.
I am trying to return a sum total figure from a stored procedure by using the output parameter. When I execute the stored procedure in SQL it returns 0 or a valid number like it should but when I try to use the webmethod listed below I keep getting a 0 even when I should get a valid number back.
ALTER PROCEDURE spGetCustSum @CustomerCode CHAR(4), @Sum AS INTEGER OUTPUT AS BEGIN......
Am I missing a step or have some wrong code in this method?
I am having some trouble with the below code snippet. It is a stored procedure which executes on load that has an output parameter which should display in a label. Familiar which Vb however not so much in C#.
I have a gridview that has the header row modified in order to add new records; the gridview is bound to a sqldatasource control. In my code behind, i handle the insert in the following manner:
[Code]....
I know the insert is occuring because the new record shows up in the grid after the databind, but the output parameter is not picking up the scope_identity() value...what am i doing wrong with the output parameter?
I'm converting my application from using System.Data.OracleClient to Oracle.DataAccess.Client and I've noticed some weird behavior.
I am calling a stored procedure that sets an output parameter value. Under some circumstances, a null value gets assigned to this value and I need to detect it.
The old Microsoft driver for Oracle would read the value as an empty string. However, ODP is returning a value {null} (per Visual Studio's debugger), which is not equivalent to null, DBNull.Value, nor an empty string. As a result, the code doesn't branch correctly now.
I have a GridView sourced by a SQL Server stored procedure with several databound fields, including a money column for item values. My stored proc returns the data through a SELECT and everything looks good. The stored proc also has a single output parameter that sums the total value of the displayed data, and this value is displayed in a label above the GridView.
in order to allow my design to keep recently inserted record on a formview i decided to use an output parameter.Currently I have a data layer helper and a class that allows my table to have crud operations. I have modified my insert stored procedure to the following:
My stored procedure requires an input parameter -- @CompanyName -- and has one output parameter - @CompanyID. This is how I always handled stored procedures that did NOT use output parameters. How do I grab the value coming from the output parameter?
I have stored procedure that increments a number. I am supposed to use the newly generated number and insert it into a table. My question is how do I execute the stored procedure, with a hardcoded value of 3 that it expects as a paramter, receive the number it generates as the output parameter and use it in the insert statement.
Here is the stored procedure code:
CREATE PROCEDURE [dbo].[Generate] @myid int, @next_no int output AS update mytable set mynumber=mynumber + 1, @next_no = number where myid=@myid RETURN
Here is my insert statement, that I tried and it failed:
I am trying to get the uniqueidentifier value from a insert SP and retreive that using a sqldatasource and pass that value to store files in the relevent folder.
I always thought we had to use a DataReader or a Dataset to read a given SQL data but i realized that it is not necessary to use them to read an SQL Output Parameter(im not a SQL expert).
I have article.aspx page that there is some Textboxs and fileupload control and insert when users click on btnInsert their data insert into database below is Behind code
i have 2 questions about output cache:1.is it just me , or does it seems that it is used only after the second time that the user reaches the webpage? if so, why, and how can i tweak it to my needs? my guess is that it wouldn't be logical to cache every time a user reach a webpage, but only when it happens enough times.2.i know that i can use "varybyparam" for using the output cache when the parameter doesn't change , but it seems that it would use the output cache even if there is no parameter , or if the specified paramter is not there. is there a way to overcome this?3.an old question that somehow marked as "answered" , yet i didn't solve : suppose i created a user control and i gave it values through the CTOR via the aspx file . is it possible to show the values from within the split/design mode? remember that i've talking about ASP.NET and not simply C# winforms . i write this because this question was on :[URL]and the answer that i got was for C# and winforms . i've tried to do the same for ASP.NET , but i've failed.
