I have this storde procedure that I add to my dbml file, when I do that it does not recognize the return type. The return type is a string, how do I set that it should be a string?
View 6 RepliesI have a stored procedure in SQl and i am calling through Entity framework through import functions. Stored procedure is returns columns from 2 different tables.. now what should be return type at Entity framwork end ?
View 1 RepliesI have an update function in my data layer which is defined as:
public int UpdateRBTable(parameters ...) This calls a SQL Server Stored Procedure to perform an update function on the database.
The process does its job for updating the table. However, the stored procedure has a return value (which indicates how many rows were updated), but this return value is not returned to the application. The application always shows that a zero was returned from the stored procedure.
I have a SQL table containing a timestamp column. This table is displayed in ASP using GridView control. The timestamp column is indicated in the DataKeyNames property of the GridView. I'm using TemplateFields for all columns and a ItemTemplate HiddenField control connected to the timestamp column using Eval.
<asp:TemplateField
ItemStyle-Wrap="false"
Visible="false"
HeaderText="timestamp"
SortExpression="timestamp">
<ItemTemplate>
<asp:HiddenField
ID="gv_hid_timestamp"
runat="server"
Value='<%#
Eval("timestamp") %>'
></asp:HiddenField>
</ItemTemplate>
</asp:TemplateField>
The data is displayed properly. I'm trying implement the optimistic concurrency in C# using the value of above mentioned timestamp and a stored procedure. The SQL stored procedure expects the @timestamp as varbinary(8). I'm not sure how to pass the value of gv_hid_timestamp back to the stored procedure. I'm using the following:
command.Parameters.Add("@timestamp", SqlDbType.Binary).Value = Byte.Parse(((HiddenField)gv.Rows[row].FindControl("gv_hid_timestamp")).Value);
resulting in the following error: "Input string was not in correct format." (I also tried different data types but with similar result). I want to be able to pass this parameter programmatically from C# and not have to specify it on the UpdateParameters list.
I have a stored procedure with 6 input parameter and 4 output parameter. In My asp.net - C# code I execute the stored procedure and return the parameter, first of all it gave me this error :
Procedure or function w_create_order has too many arguments specified. That I'm not sure why is that because the number of parameters is right, the only thing is may be the way that I used is not right.
Second, I would like to show the parameter in the label control in my page, I'm not sure how to do this.

I have a stored procedure with 6 input parameter and 4 output parameter. In My asp.net - C# code I execute the stored procedure and return the parameter. Stored procedure executed correctly, but the return values are empty. I would like to show the return value on the page. Stored procedure works fine and return value in sql manager.
This is my code:
SqlCommand cmd = new SqlCommand("w_create_order", connection);
cmd.CommandType = CommandType.StoredProcedure;

cmd.Parameters.AddWithValue("@in_order_class", "WEB");
cmd.Parameters.AddWithValue("@in_owner_code", "OP");

cmd.Parameters.AddWithValue("@in_cus_key", null);
cmd.Parameters.AddWithValue("@in_lab_key", null);
cmd.Parameters.AddWithValue("@in_invoice_number", null);
connection.Open();
cmd.ExecuteNonQuery();
//output parameters
//output parameters
cmd.Parameters.Add("@ord_key", SqlDbType.Int, 500);
cmd.Parameters["@ord_key"].Direction = ParameterDirection.Output;
cmd.Parameters.Add("@ord_invoice_number", SqlDbType.Int, 500);
cmd.Parameters["@ord_invoice_number"].Direction = ParameterDirection.Output;
cmd.Parameters.Add("@via_ship_via_code", SqlDbType.NVarChar, 500);
cmd.Parameters["@via_ship_via_code"].Direction = ParameterDirection.Output;
string message = (string)cmd.Parameters["@via_ship_via_code"].Value;
cmd.Parameters.Add("@ord_ship_after_date", SqlDbType.DateTime);
cmd.Parameters["@ord_ship_after_date"].Direction = ParameterDirection.Output;
Label1.Text = message;
connection.Close();
I'm having a hard time to return a string value. I usually do this by passing an int, which works just fine. Now, I need to pass a string but couldn't. Is this possible? Or int is only type that SQL can return?

I'm not so familiar with stored procedures but I'm interesting in moving most of my web selects to stored procedures. I'm working with .net based website and all my data access is something like this:
[Code]....
But now I want to improve some process and make tunings. For that I want to use stored procedures, so instead of the "SELECT ...." sentence I'll put stored procedure name. My problem is how to return a table from one.
Long story short, it would be a lot easier for me to just return two values (from a many-column table, like combining columns) than to combine them in my asp project. I'm just having many problems with binding to a dropdownlist, and it would be easier not having to guess what index the column is I need :)
So, let's just say my table, "Building", has 5 columns - BuildingID, PracticeID, PracticeName, Address, & Zip (there are many more in my real table).
I already have a stored procedure that is "SELECT * FROM Building ORDER BY PracticeName". What I would like, is something that returns column values together with literal characters, like:
PracticeID - PracticeName (Address) AS First
I know I could use "SELECT PracticeName AS Name FROM Building" to simply change the name of the column I'd receive, but I want to add literal characters ( "-" and "(" and ")" and " ") with specific columns I choose.
Since I have about 20 columns in my table and I only want about 6, I don't need to SELECT *, but only those 6. That's easy enough. But since I would still like these six columns combined, I'm not sure what to do.
Again, what I want is to return something like:
PracticeID - PracticeName (Address) AS First BuildingID - Zip AS Second the "-" and "()" and " " need to be included and returned from SQL, not when I retrieve them)
How can I execute a stored procedure using sqldatasource and get the return value in vb.net.
View 2 RepliesIn my asp.net page I pass paremeters to a stored procedure and then inside a try blog the foloving line: affectedRows = ssqldbsorce.insert
never returns expected result from stored procedure.
Inside stored procedure event if I explicitely write the following line "return 5" for example, it never returns 5, only -1, 1, 2
For example here a very simple one without output parameters(I still should be able to return a value without output parameters, right?):
ALTER PROCEDURE [dbo].[createUser]
@regCode varchar(10)
AS
SELECT * FROM dbo.reg_code WHERE reg_code=@regCode
....
---other statements, and for the sake of the example lets return 5
RETURN 5
Is there something wrong with doing it thi way, here is also a tutorial, according to which it should work just fine: [URL]
Is there another way maybe in the assp.net page to capture the value in the variable from a stored procedure.
i want to retrieve the return value of following stored procedure in my Data Access Layer of ASP
CREATE PROCEDURE Procedure_login
So I am getting this error message:
Cannot implicitly convert type 'System.Data.SqlClient.SqlParameter' to 'string' I have a stored procedure on SQL 2000 returning an email from a database table (aspnet_Membership). The email type from the table is nvarchar. I have a method (in C# in the code behind) that gets that value. But the debugger doesn't like the last line:
return returnEmail; // returnEmail is a string variable we created to capture the stored procedure's return value
I've tried doing returnEmail.toString() in several places, but still get the same error message for the last line of code (returning the email).
This is the stored procedure:
I have a stored procedure which returns a value to state if the userlogin is valid. but i want to return the data and store it in a data session as i will require the user details in the checkout page.
is it best to get individual parameters out of the stored procedure then assign the variables to a datatable which is then assigned to session Or how can i get all the details returned from the stored procedure for the table? not sure which would be the most effective solution?
While using an insert query for a certain table, can I used a select statement to know whether there's an already existing value in the stored procedure using a return value where insert occurs? Or do I need to separate a procedure?

View 1 RepliesI am using .net framework 3.5 and sql server 2008.
In my project coding, I want to call stored procedures in sql server 2008.
return value is the object list which references the entity.
But I have the questions.
If in the entity named as "order", is it matching the properties or created through entity constructor??
In my case, I have two properties and one constructor which match one property.
public class orders
{
orders ( string orderid)
{
this.orderid=orderid;
}
public string orderid {get;set;}
public string orderno{get;set;}
}
I am realitivly new to c# and I am trying to do something that is probably simple, but I might just be over thinking it.What I want to do is have an image change based on a return of a sql data call. I am using a stored procedure that reads values and uses a case to switch between red, yellow, green for status. For example, I have nine items that the SP goes through and returns one of the colors. What I would need is if it detects a red, change the image to red and so forth. Now, when I execute the SP in C# I can get the data but it always just reads the last value. So if it had a red in there and the next one is a green, it uses the green. I even thought about reading the colors and using an IF statement adding the values to determine which color should be used.

When it is bound to a datagrid. I do a grdELTCompletions.DataBind() and it shows that it's SELECTING, but returns nothing. I can execute the SP in MS SQL and it works fine. I just need know what elements of either the datasoure (sql to execute the SP) or the datagrid to find the error. Or even if there is a SQL log I can look at..
