Databases :: Detecting Nulls In Output Parameter Using ODP?
May 17, 2010
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.
Here's how I'm declaring it using ODP.net:
cmd.Parameters.Add("p_status", OracleDbType.VarChar2, 200, DBNull.Value, ParameterDirection.Output)
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 am using a cursor to iterate through a small set of record (28), perform some maths on each record and then update the record / row.
The problem is the cursor pulls in all nulls for every field in every row
It also gives me 28 rows, 28 times (see below)

environment: VS2008, MySQL 5.1.45, .net Connector 6.2.2
Error msg:
NoNullAllowedException: Column 'idNames' does not allow nulls.
The MySQL DB has on "idNames" (Primary Key) a tick-mark for: primary Key, Not Null, Auto-Increment Also: I can add/retrieve records via the 'MySQL Query Browser'; I see the data via VS2008 'Preview Data'!
As said in the comment below; when the 'idNames' is explicitely given the rows.add works fine. So it seems that I miss something around the 'auto-increment' business!

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?

I am using LINQ.I have stored procedure as:
ALTER PROCEDURE [dbo].[usp_ATI_OA_GetCalculatedValue]
@OredrID BIGINT = 0,
@SubTotal MONEY OUTPUT,
@ShippingTotal MONEY OUTPUT,
[code]...
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)?
My stored procedure looks like this:

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

Am I missing a step or have some wrong code in this method?

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:
EXEC @GetNo = Generate '3'
Insert into customers (custid, name, phone ) values
( @GetNo, 'MSFT', '800-345-5678')
