DataSource Controls :: .net Call To A Sql Server Proc?
Jul 7, 2010
I have a .net 3.5 page that calls a short sql server procedure which compiles fine. When the code is called
from a webpage(.net) it runs the first time it is executed. However on the second time it throws an error saying "There is already an object named 'strPKHoldUp' in the database." StrPKHold is a variable that I
declare in the code as seen below.... I have never had a problem before with declaring a variable and having it "save or cache" in the database so you can use it again. Any idea how to solve this? I tried
moving the DECLARE statement around a little bit but that didnt. I changed the variable name to something else and it works one time but fails after that...

i'm a total newbie with asp.net mvc and here's my jam:
i have a 3 level list box which selection on box A shows options on box B and selection on box B will show the options for box C.
I'm trying to do the whole thing in asp.net MVC and what i see is that the nerd dinner tutorial uses the ORM method.
so i created a dbml to the database and drag the stored proc inside. i create a datacontext object but i don't quite know how to connect the result from the stored proce which should be multiple rows of data and make it into a json. so i can keep all the json data inside the html page and using jquery i could make the selection process faster. i don't expect the data inside the three boxes to change so often thus i think this method should be quite viable.
Questions:
So how do i get the stored proc part
to return the data as json?
i've noticed some tutorial online
that the json return result part is
at the controller and not at the
model end.
Why is that?
Edit
FYI, i find what i mostly wanted to do here.
For the json part, i referenced here.

I have a table with two indexes, PK_WClient (clustered) and SMonths (non-unqiue, non-clustered), we have a data import that works on the .net side, it imports data via C# into the table. Every time we complete the import the sections of the asp.net site that use that table are very slow, just when pulling the new records, old records are fine. so we reindex that table for both indexes and things are fine again. Rather than us having to reindex manually in sql server 2005 each time, is there a way to get this to happen via a stored proc or from the c# side? this way when the client gets the project, we don't need to run the index, they can just use the site to import data and behind the sceens the reindex can happen once the import is done.

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.

I have to write stored proc to get the daily transaction for a specified date. Right now what i do is everytime i log a transaction in table3 I update table 2 with the count. Then i use table 2 to write the stored proc and to get the desired result. I have pasted my stored proc below with the output. My problem is when another subsystem is added in the AppInfo table i need to update my stored proc because i have hardcoded the subsystem name.

I have a stored proc. that returns the USL & LSL values for each of the 8 different Metrics. say, Defect Density (Upper Specification Limit) USL = 0.30 & Defect Density (Lower Specification Limit_ LSL = 0.05). Simillarly for 8 different Metrics. Why I need these Spec. Limits ?...Because I want o compare my project's Metrics Value displayed in the Grid View with the corresponding USL & LSL value of the same Metrics. IF Metrics Value is outside of USL & LSL Then I want to Mark the Metrics in Red Color.

I've modified an existing strored procedure. It originally had one ouput parameter in the stored proc and it was set up as follows in the c# code that called it:
cmd.Parameters.Add("@Var1Param", SqlDbType.BigInt);
if (Var1 == 0)
cmd.Parameters["@Var1"].Value = DBNull.Value;
else
cmd.Parameters["@Var"].Value = Var1;
cmd.Parameters["@Var1"].Direction = ParameterDirection.InputOutput;
cmd.ExecuteNonQuery();
// Get Var1
Var1= dataMorph.ToInt64(cmd.Parameters["@Var1"].Value.ToString());
Just to clarify, this parameter was declared as OUTPUT in the stored proc but as inputoutput in the C# code. This worked fine. I have added another parameter to the same stored procedure and I want to retrieve both from the C# code. The C# code now is as follows:.................................
