Send Null Values To A Stored Procedure In C#
Jul 11, 2007
Hi
I am new to C# . I have a stored procedure which takes 4 parameters
GetSearchComplaint( Comp_ID , strViolator, strSts, FromDate, ToDate), These parameters can be null.
And i have 5 textboxes from which i send the parameters.
I am validating the input like this :System.Nullable<int> Comp_ID;
if ((txtsrchCompID.Text).Trim() == "")
{Comp_ID = null;
}else if ((txtsrchCompID.Text).Trim() == "")
{
try
{int i = int.Parse(txtsrchCompID.Text);
Comp_ID =i;
catch
{mesage += "Complaint ID is not valid";
}
}
When i run this i get this error ---'Use of unassigned local variable 'Comp_ID'
I get the same error for FromDate(DateTime) and ToDate(DateTime) . but not for string variables strViolator and strSts.
How do i pass the null value to the stored procedure? pls help..

I have created some stored procedures that I wish to share with another user in another database. How can I extract this code, other than cut and paste, since I have quite a few? Is it possible to duplicate database object "stored procedures"? How about a script that would recreate them in the target database?
Any help would be appreciated.
Thanks!

I thought I could just copy over some asp.net code like: System.Web.Mail.MailMessage mailMessage = new System.Web.Mail.MailMessage();
But VS2005 doesn't seem to want me touching System.Web.Mail.
Any ideas?
Thanks,

I have a pivot transform that pivots a batch type. After the pivot, each batch type has its own row with null values for the other batch types that were pivoted. I want to group two fields and max() the remaining batch types so that the multiple rows are displayed on one row. I tried using the aggregate transform, but since the batch type field is a string, the max() function fails in the package. Is there another transform or can I use the aggragate transform another way so that the max() will work on a string?

Version: ASP.Net 2.0Language: C#Hello Everyone!I'm saving data from a function to an SQL Server 2000 db via a stored procedure. There are a few fields which are conditional and thus need not be passed to the procedure everytime. Under those circumstances I need to store null values in the fields.The problem is if I the value of the parameter as null, VS throws the error that a required parameter is not passed. I tried setting 'IsNullable' property of the parameter to true but it works for only those fields who are declared NULL in the stored procedure (For e.g. @DOB DATETIME = NULL).Strangely, this works well in classic ASP.Does anyone know how to accomplish this? Note, altering stored procedures is not an option for me.Thanks a lot!

If I have a stored proc which has 2 input variables and for example
the 2nd one is null or not provided what is the best way to turn this null
into a wildcard. If the second one is an int and not provided should I
but a checknull statement in the proc and convert this to a wildcard %. I believe if I do I need to change the where clause "where field1 = @var "
to where field1 like @var". Any input appreciated

Hi Everybody,
I am trying to setup a stored procedure that runs through a Reminders table and sends an email to users based on DateSent field being smaller than todays date. I have already setup the stored procedure to send the email, just having trouble looping through the recordset.
Code Snippet
CREATE PROCEDURE [dbo].[hrDB_SendEmail]
AS
BEGIN
DECLARE @FirstName nvarchar(256),
@LastName nvarchar(256),
@To nvarchar(256),
@ToMgr nvarchar(256),
@Subject nvarchar(256),
@Msg nvarchar(256),
@DateToSend datetime,
@Sent nvarchar(256),
@ReminderID int,
@RowCount int,
@Today datetime,
@Result nvarchar(256)
-- Get the reminders to send
SELECT
@ReminderID = r.intReminderID,
@DateToSend = r.datDateToSend,
@FirstName = e.txtFirstName,
@LastName = e.txtLastName,
@To = e.txtEmail,
@Subject = t.txtReminderSubject,
@Sent = r.txtSent
FROM
(auto_reminders r INNER JOIN employee e ON r.intEmployeeID = e.intEmployeeID) INNER JOIN ref_reminders t ON r.intReminderType = t.intReminderTempID
WHERE
(((r.datDateToSend)<20/12/09) AND
((r.txtSent)='False'))
-- Send the Emails
WHILE(LEN(@To) > 0)
BEGIN
EXEC @Result = sp_send_cdosysmail @To, @ToMgr, @Subject, @Msg
END
-- Mark the records as sent
IF @Result = 'sp_OAGetErrorInfo'
BEGIN
SELECT @Sent = 'Error'
END
ELSE
BEGIN
SELECT @Sent = 'True'
END
UPDATE auto_reminders
SET
auto_reminders.txtSent = @Sent, auto_reminders.datDateSent = @Today
WHERE
intReminderID = @ReminderID
END
GO
From the code you can probably tell I am new to writing stored procedures, so I apologise for any obvious errors. My major problems are :-
how to loop through each record
how to get todays date
whether the struture of the procedure is correct
Also, if you think there is an easier way or a better method, please suggest it. I am open to any suggestions you may have,
Thanks in advance

Hi !
I have a problem with the unique identifier and don't know how to solve it.
I have a stored procedure, called from my ASP.NET page, which inserts a new record into a table. I need to get the Id of the row just inserted in order to use it as a parameter of another stored procedure which inserts a new row with this value and other values.
I tried with SCOPE_IDENTITY but i don't know how to ask for this value to the first stored procedure and stored it into an ASP variable.
Dim cmd As New SqlCommand
cmd.CommandText = "Insertar_Contacto"
cmd.CommandType = CommandType.StoredProcedure
cmd.Connection = connect
Thanks!!

Hello everyone,I need advice of how to accomplish the following:Loop though records in a table and send an email per record. Emailrecipient, message text and attachment file name - that's all changesrecord by record.Is it doable from a stored procedure (easily I mean, or am I better offwriting a VB app)?

If match, extract matching records for that Category from Both Tables (Categories.CategoryID, Products.ProductName, Products.QuantityPerUnit) and e-mail them based on E-Mail Address from Parent (Categories ) Table. If no E-Mail Address is listed, do not create output file. In this instance Category Id = 3.Basically I want to select 1st record from Parent Table (Here is Category) and search for all matching Products in Products Table. And Create an E-mail and sending just those matching records. Repeat the same process for remaining rows from Categories Table. I am expecting my E-Mail Output like this: For Category Id: 1

My Tables are in SQL 2005. I was thinking to read the Category records in a Data Reader and within the While Loop, call a SP to retrieve the matching records from Products Table. If matching records found, call System SP_Mail to send the E-mail. The drawback with that for every category records (Within While Loop) I need to call my SP to get Products Data. Will be OVERKILL? Ideally I would like extract my records with one call to a SP. Is there any way I can run a while loop inside the SP and extract Child Data based on Parent Record? Any Help or sample URL, Tutorial Page will be appreciated. Thanks

I'm trying to write a stored procedure for a search criteria. A user will have few controls on ASP.Net webpage to enter/select the search criteria, based on which , it returns the data.
A Textbox( to enter Username), A Textbox (to enter Employee name),
A DropDownList (To select the profile. Its Id is sent as parameter) &
A DropDownList (To select status). This is where I am stuck.
The last dropdown has 3 list items
1. --All-- value is null/empty
2. Active value is 0
3. Blocked value is 1
Though the Database table will have only 0's and 1's for the status column, the user should be able to see all records when -all-- is selected.I also tried excluding the status parameter and its condition, but no luck either way.

Hello,I'm trying to pass a null object to a stored procedure to update a SQL Table boolean field with a null value. My SQL Table boolean column allows nulls.I'm using an InfoObject which has several properties all corresponding to fields in the SQL Table. One of those fields is a boolean. I create an instance of the InfoObject in my code and assigns values to the various properties. The boolean property in question (call it InfoOjbect.BooleanProperty) is not assigned anything. I then call my StoredProcedure passing the InfoObject to it (using the DotNetNuke DAL architecture) and the final result is the Table's boolean column is populated with a 0 and not a NULL. If I explicitly define the InfoObject.BooleanProperty = null.nullboolean before passing it to the Stored Procedure, the same thing happens. How do I pass a null to the SQL database for a boolean field? I've tried making InfoObject.BooleanProperty = dbnull.value but it won't let me do this saying "dbnull cannot be converted to a boolean." Do I have to explicitly create my InfoObject properties to allow for a null to be assigned to it?Any help would be greatly appreciated. I'm using the DotNetNuke DAL architecture passing my InfoObject through a dataprovider to the sqldataprovider which calls the SQL Stored Procedure to add the new record to the Table.Thanks in advance for any help.

If you write a stored procedure to "SELECT MAX" from a table and the answer is null since the table is empty, how is the null answer returned to the program from the stored procedure? Do you actually get the letters "NULL" or do you just get a space? How should you define your variable in your program?
Thanks in advance!

In a VB.NET script, I am adding the dbnull value to a parameter that will populate a smalldatetime column:
cmd.Parameters.Add("@unitHdApprove", System.DBNull.Value.ToString)
The stored procedure then defines the input as smalldatetime:
@unitHdApprove smalldatetime,
However, the result is that the record is inserted with 1/1/1900 as the date value, instead of <NULL>.
I'm guessing that this occurs because the conversion of a '' to date will return 1/1/1900, and VB requries the parameter value to be a string (at least with this syntax), so System.DBNull.Value.ToString really equals ''.
I've rewritten the proc to accept the date as a string instead, and then for each date, cast it to a smalldatetime or set it to null as is appropriate. But this is a really bulky way to do things with more than a few dates! Is there any way to change what is in my VB code so that the procedure will insert the actual null value?
Thanks,
Sarah

I have a table which has 10 columns which make up the secondary key. 1or more of these columns can be set but the remaining columns in thesecondary key will be null. For example :id k1 k2 k3 k4 k5 k6 k7 k8 k9 k10 data-------------------------------------------------0 1 1 - - - - - - - - test01 1 1 1 - - - - - - - test12 1 1 2 - - - - - - - test23 1 1 3 - - - - - - - test34 1 1 3 1 - - - - - - test45 1 2 1 - - - - - - - test56 1 2 2 - - - - - - - test6Each row represents a node in a tree structure, the secondary keycolumns point to which node in the tree. The above example has onenode in tree branch 1, three nodes in tree branch 1-1, one node inbranch 1-1-3 and two nodes in branch 1-2.My question is how can I write a single stored procedure to returnonly the nodes in a given tree branch without needing logic based onlooking for NULL parameters. I have written the stored procedurebelow. If I want to retrieve all nodes in branch 1-1 (ie; test1, test2and test3) then I want be able to call :execute "mysp Test" 1, 1But this only returns a single record, test0. The reason for this isobvious if you look at the stored procedure. What I really need is wayof sayingexecute "mysp Test" 1, 1, NOT NULLso that it returns all records in branch 1-1 where Key3 is NOT NULLbut all subsequent keys are null, ie; Key4-Key10 are NULL. The storedprocedure must work with any number of secondary keys though, so Icould use it to call :execute "mysp Test" 1, 1, 3, NOT NULLwhich would retrieve test4.Can anybody help me out here?Thanks for reading.Here's the stored procedure as it stands :CREATE PROCEDURE [dbo].[mysp Test]( @key1 smallint,@key2 smallint=NULL,@key3 smallint=NULL,@key4 smallint=NULL,@key5 smallint=NULL,@key6 smallint=NULL,@key7 smallint=NULL,@key8 smallint=NULL,@key9 smallint=NULL,@key10 smallint=NULL ) ASselect * from TreePositionTestwherekey1=@key1 andkey2=@key2 andkey3=@key3 andkey4=@key4 andkey5=@key5 andkey6=@key6 andkey7=@key7 andkey8=@key8 andkey9=@key9 andkey10=@key10GO

( @a int, @b int, @c varchar(50), @d varchar(50))
now from front end(I'm using c#.net)
I want to send the values according to some criteria
So in the process...I've only values for @a & @c ...
so In order to reduce the code of sending Null values explicitly to other parameters...
can't I set like default values for it so that If I don't send values to certain parameters it will have the default value or Null value.
like I want something like this:
create procedure dummy
( @a int NULL, @b int NULL, @c varchar(50) NULL, @d varchar(50) NULL)

I have a stored procedure where I gather some data and then insert the data into a table variable. I then attempt to go through each row of the table variable, asign the values to local variables to be inserted into other tables. However, the local variables show as NULL.BEGIN
DECLARE @tblcontact table
(
SOKey int,
Cntctkey varchar(60),
Cntctownerkey int,
LASTNAME varchar(32),
FIRSTNAME varchar(32),
WORKPHONE varchar(32),
EMAIL varchar(128),
processed int DEFAULT 0
)
INSERT INTO @tblcontact (SOKey, Cntctkey, Cntctownerkey, LASTNAME, FIRSTNAME, WORKPHONE, EMAIL)
SELECT ...
DECLARE @ID int,
@sokey int,
@cntctkey int,
@cntctownerkey int,
@name varchar(65),
@email varchar(128),
@phone varchar(32)
WHILE EXISTS (SELECT * FROM @tblcontact WHERE processed = 0)
BEGIN
SELECT @ID = MIN(SOKey) FROM @tblcontact WHERE processed = 0
SELECT @cntctkey = (CAST(LTRIM(REPLACE(Cntctkey,'CN',' '))AS int)),@cntctownerkey = Cntctownerkey, @name = FIRSTNAME + ' ' + LASTNAME, @phone = WORKPHONE, @email = EMAIL, @sokey = SOKey
FROM @tblcontact
WHERE @ID = SOKey AND @cntctkey <> '43778'
INSERT INTO tciContact (Cntctkey, Cntctownerkey, CreateType, EMailAddr, EmailFormat, EntityType, ExtUser, Name, Phone, UpdateCounter)
VALUES (@cntctkey, @cntctownerkey, '0', @email, '3', '401', '0', @name, @phone, '0')
UPDATE tsoSalesOrder
SET Cntctkey = @cntctkey, UserFld4 = 'temp'
WHERE SOKey = @sokey
UPDATE @tblcontact
SET processed = 1 WHERE @ID = SOKey
END
END
