DataSource Controls :: Return Value From Stored Procedure To C# Code Behind?
Mar 16, 2010
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).
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..
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?
i have a grid bound to sqldatasource control which gets its data from stored procedure. in page load event i code a dropdownlist where i take the selectedvalue parameter for the parameter query. only when a second dependant dropdownlist is selected (coded in dropdownlist1 selected event)is data returned ?
Is it possible to return multiple values from a stored procedure? Basically, if I execute the stored proc on the C# side, then on the SQL side I do multiple calculations. Let's say I have 5 int values I need returned to the C# side.
Am stuck with this sql stored procedure/asp.net vb.
I want to call the stored procedure and for it to return a true or false if successful ie username and password match.
My stored procedure works fine, and I can call it from my vb, however I stuck as to how I get it to return a result of true or false, 1 , 0. I just get a blank page.
Initially, I have tried to use stored procedure. But I changed my mind and preferred to call sql query in codebase with command text. However, it stills tries to find initially-called stored procedure (which is neither called or exists).I think that it is related caching. But I tried it with different browsers it did not work.What might be the reason?
I am trying to allow users to grab their stored procs and call certain ones from within code. I can get the stored procedures and then fill a dropdown with them, but what I cannot find at this point is how to get the parameters that each stored procedure needs. I would like, once an SP is chosen from the dropdown to make a call to the db with that sp name and grab its paramter list so I can report what needs to be sent in to the user.
I 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.
The database I am using has a schema called EQB and as such, my stored procedures are named as EQB.usp_SelectFunds, EQB.usp_SelectAccount, etc.
On the select tab of the Configure Data Source screen, I choose to use a stored procedure. The dropdown shows my stored procedures, however, the schema name does not show up in front of the stored procedures in the drop down. I see only usp_SelectFunds, usp_SelectAccount, etc.
I select one of the stored procedures and when I click TEST, I get the message that the stored procedure is not found. If I instead choose to use a SQL statement instead on the configuration screen and enter EXEC EQB.usp_SelectFunds and click TEST, it works fine.
Why are my stored procedures not showing up correctly in the stored procedure drop down and how can I fix this?
how can I create stored procedure and write my select statement in it, I know how to create dataset then put type stored procedure and assign it to the sp ... what I want is writing my sp... how can I make it ?
check the following code, this is what I want to write put I don't know where or how !
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.
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 have a stored procedure and i want to return a value from that procedure and returned value i want to store in a variable Stored Procedure is create procedure simpleproc(OUT pcount int)begin set @pcount=(select count(*) from testtable); end
Now i call this proc from C# code
string query="CALL simpleproc(@count)"; MySqlCommand commond = new MySqlCommand(); MySqlParameter returnValue = new MySqlParameter("@count", DbType.Int32); returnValue.Direction = ParameterDirection.ReturnValue; commond.Parameters.Add(returnValue); commond.CommandText = query; commond.Connection = con; // I already set the connection in con and opened it commond.ExecuteNonQuery(); int count = Int32.Parse(command.Parameters["@count"].Value.ToString());
What should i have to change to get return value in count
