Passing Null / Empty String To Oracle Stored Procedure?
Mar 1, 2010
We have an ASP.NET web service that invokes a stored procedure on our DB (Oracle 11g). The problem is that the call to the procedure blows up every time an empty string is passed as one of the parameters. We're seeing an ORA-01084 error, which indicates to me that call is failing before the procedure is actually run.
Here's the procedure, minus some logic that I believe is not relevant:
[Code]....
As an experiment, I modified the web service to pass null rather than an empty strings. When null is passed in, I see an error indicating "wrong number or types of arguments in call to 'CREATEREPORT."
I also tried passing DBNull.Value whenever the params were null/empty, but that resulted in the error
Parameter 'p_column_id': No size set for variable length data type: String.
(Of course, p_column_id was the empty parameter in this case).
So, how can I successfully pass empty strings as parameters to my stored procedure? We definitely want to allow the p_column_id parameter to be empty.
we recently upgraded an application (.NET 2.0) that we maintain to use Oracle 11g. The application uses MS Enterprise Library 2.0. We've found that when the database.ExecuteNonQuery(Oracle.DataAccess.Client.OracleCommand) method is called, it bombs when the stored procedure expects a parameter as a number, but receives a string. This didn't happen prior to upgrading. If I cast the parameter to an Int, I don't recieve the error. Was something possible missed during the upgrade? The issue occurs regardless if we are hitting an 11g database, or a 10g database.
EDIT: I neglected to mention that this same issue does not occur when ExecuteDataReader is called (handles implicit conversion of the datatype).
I'm trying to pass the text value of a text box as a query string value to a stored procedure. I was hoping someone could point me in the right direction. Button Code:
[Code]....
Stored Procedure:
[Code]....
The results page datalist:
[Code]....
Code Behind of results page:
[Code]....
I'm sure i've got this entirely backwards. However if I change the NULL value in the stored procedure with some string value (eg."Donkeys") it pulls all the values that contain "Donkeys" into the datalist on my results page.
i want to send mails internally and externally for eg. i want to send mail to my boss in the company and also to the customer which doesnt belong to our domain.
[URL]
and also i want to attach an excel file which is stored in my computer. so how am i going to access that file through the same procedure and then attach the file and send it to both internal as well as external email ids.
I am trying to create a method which will access the database via a SqlDataAdapter. I have passed two parameters month and year. When I run it, I get the error "Object reference not set to an instance of an object". I have posted the complete code below. Please take a look..
I want to return all rows from a SQL Server 2008 database table into a SQL data source if a textBox field is blank. So I made a stored procedure with an if @date IS NULL clause.
Although the stored procedure seems to be working fine in Visual Studio 2008 the actual webpage displays no results.
I am guessing I have to send a DBNull value to the stored proc if textBox.Text == string.Empty. I tried the SqlDataSource1.SelectParameters.Add but it seems that I get a conversion error from DBNull.Value to string.
Is this the source of my problems or am I missing something else? How would I pass DBNull.Value to a stored proc if a textfield is blank?
i have a stored procedure to update a table. not all fields are required and some can be blank.for example, title is not required, but when it's blank i get an error
Dim ptitle As New SqlParameter("@title", SqlDbType.NVarChar, 20) ptitle.Value = objFormat.CheckSQL(title) myCommand.Parameters.Add(ptitle) ex {"Procedure or Function 'sp_UpdateUser' expects parameter '@title', which was not supplied."} System.Exception
how can i fix it so that it allows for nulls if the data field is blank?
I have a Procedure which should return only 1 Record on selecting record according to Priority.
BEGIN DECLARE @Accounts nvarchar(MAX) SELECT @Accounts = ISNULL([map_user_modules].[Accounts], '') FROM [map_user_modules] WHERE [map_user_modules].[id_user] = 231 AND [map_user_modules].[id_module] = 5 IF ((@Accounts = '') OR (@Accounts = 'All')) SELECT @Accounts = null
BEGIN Select @@ROWCOUNT as Priority2 END IF @@ROWCOUNT = 1 BEGIN Return END
BEGIN Select @@ROWCOUNT as Priority3 END IF @@ROWCOUNT = 1 BEGIN Return END
BEGIN Select @@ROWCOUNT as Priority4 END IF @@ROWCOUNT = 1 BEGIN Return END
In the above statement Suppose we take a scenario where Select @@ROWCOUNT as Priority3 is executed, I get two tables returned, One is the Table returned by Select @@ROWCOUNT as Priority3 and the other is the Table returned by Select @@ROWCOUNT as Priority2 which has no Records. How can I eliminate the Empty table that returns no records.
Via the button1_ click event I retrieve all files in a directory (Example Follows)
[Code]....
I now need to check whether this filename exists as a field in a SQL Server table. For example, if the directory retrieves a file named ExampleFile.txt which does not exist in the (Table = TableFileStore;s Field = FileRetrievals) then I want to insert the filename.
How do I construct a stored procedure to pass the filename(s) into a stored procedure as a parameter? Do I need to also create an array of filenames and pass the array into my stored procedure? Does the stored procedure belong within the foreach loop?
I have a SQL stored procedure on a SQL server that uses a variable to create a new database. This works in SQL I have a connection string that works I have added a sqldatasource to a webform, and configured the datasource to connect to the remote SQL database and am able to select my stored procedure. I am able to bind the variable to a control in the sqldatasource wizard (often two of the same control appear- if that is significant)
When I test the sqldatasource in the configuration wizard and put in a manual entry, the procedure runs and works
It is on the web page I am having troubles. I want the user to enter a name in a text box, click a button/link, and run the procedure. Ive used buttons and links...but not in the right way I think, becuase when I click them the stored procedure doesnt run.
As mentioned above, I have selected the right control in the sqldatasource wizard. So what do I need to do now?
How do I pass a dataset object to a stored procedure? The dataset comprises multiple tables and I'll need to be able to access them from within the SQL.
I have an .ASPX form. All I want to do is simply "Submit" the form field values into a database.
"I have been tasked with re-writing the entire .ASPX form to use "Stored Procedures" instead of a "SQL-String" to insert form values. I think I have most of the form submitting to the database, except the "Radio Buttons" just say "NULL".
I do not know how to progam the Radio Buttons to insert the value (Yes, No, N/A) the user chose into the database. I have GOOGLED but cannot find an answer, and some answers are too complex for my level of understanding at this point.
I need to take the following code and change it so it just calls a Stored Procedure. If you could show me "Stored Procedure" code and how to change my current code to work with the Sproc it would be much appriciated. Here is the code.
I have "11" groups of Radio Buttons I need to change. Here is an example of one of the rows.
<tr> <td><input type="radio" name="group1" value="yes"></td> <td><input type="radio" name="group1" value="no"></td> <td><input type="radio" name="group1" value="N/A"></td> <td><asp:Label ID="Label22" runat="server" Text="Surfaces exposed to corrosives pH between 5 and 9."></asp:Label></td> </tr>
Summary: I just want to call a stored procedure and store the value the user chose into my database.
I need to send an array of strings to a stored procedure and then use that array of strings to create a filter of the data returned.for example I need need to send the following array to the strored procedure:
[Code]....
and use that array to run the fillowing sql command:
I'm strugling with this problem for quite some time and I've tried many different solution but nothing works. In my application there are 3 textboxes. First is mandatory but user can leave second and third empty. I that case I want that application insert NULL.
Here is .aspx code:
[Code]....
c# code:
[Code]....
Stored procedure:
[Code]....
I've tested code when user fills all 3 textboxes and it's working fine. If one second or third (or both) textbox(es) is(are) empty I wish to insert NULL into table. I've tried with DbNull.Value, null, 0, "3232131" and nothing works. I always get error Input string was not in a correct format. which is strange since code works when 2. and 3. tbs are filled and I'm not inserting string. And I've specified that table allows inserting of null values.
I am a rookie developer here and I have tried looking around for an answer but I am little confused. I have a stored procedure that calls multiple stored procedures when I go to create a new contact.[Code]....
I though I could use the OUTPUT Command to copy out the NewContactID but I am getting all kinds of syntax errors. I am confused as to what I am missing here.
I am using DAAB with stored procedures. I use stored procedures more then once if possible. If I add a parameter later in stored procedure, I have to supply value for this in functions where it is even not being used as well, other wise it shows an error that number of parameters are not same. if I add parameter in last of parameter list in stored procedure and set a default value for it and I may have not to provide value for this from functions where I am not using it.
