Any Easy Class Method To Update About 100 Fields Of A Database Using Stored Procedure?
Feb 1, 2007
Hi all,
I am using C# for ASP.NEt 2003.
I would like to know if there is any easy method to update a database with about 100 fields in it.
At present, I pass all the values of the controls on the web form to the stored procedure as parameters like :-
myCommand.Parameters.Add("@CustomerID", SqlDbType.Int).Value = txtCustomerID.text
Like this, I add all 100 parameters.
Is there any easy method to do it using a class or any other methods?
Thanking you in advance,
Tomy

I am new to Sql, so I think this is a really easy question.
But I am working on a 2005 MSSQL database.
When I add columns to an existing application with data and tables already being used, and the new column will be set to Database Null.
What is an easy way to quickly add the data to all the rows in the table.
For example if I am adding a checkbox, I've been doing it manually, add the column, change all the rows to False, one by one.
And then I can change it to Disallow DBNull.
As I get more and more users this could be a very time consuming process.
So the name of the Table is classifeds_Ads and let's say the column I want to add is Bonus and it needs to be filled with False.
How do I do this???
Thank you in advance

Hi Everyone,
I ran into something interesting this afternoon as i was trying to create a stored procedure.
<code>
Create Procedure GrabRecentPresentations
As
Select * from tablePresentations Order By PresentationID DESC
Go
</code>Works fine.. but if i try to do this
Create Procedure GrabRecentPresentations
As(
Select * from tablePresentations Order By PresentationID DESC
)
Go
I get an error: incorrect syntax near the keyword 'Order'
It seems that by adding those two ( ) i get the error... does anyone know why this happens or a way to make it so that i can keep those beloved parentheses? Furthermore.. why does the error only pop up when i have those in? THanks

Hi,Plz, I need some info (SQL2000) :)A stored procedure is like this:"Select table1.id, table1.txt, (select table2.nr from table2 wheretable2.fk_table1=table1.id) as nr where table1.id<>10"The essence here is that "select table2.nr from table2 wheretable2.fk_table1=table1.id" returns either the integer in table2.nr, or NULLif there isnt a match. The whole sentence runs EXTREMELY slow...3-4 sec.What is wrong?"select table2.nr from table2 where table2.fk_table1=table1.id" runs quicklyoutside the stored procedure. The original sentence without the "nr" (Selecttable1.id, table1.txt where table1.id<>10) runs quickly too...But together it slows down dramatically..why? I should mention that thesub-query could return NULL if theres no match in table2...But i cant seewhy that should slow things down (remember - it runs fine outside the SP)?Thx,PipHans---Outgoing mail is certified Virus Free.Checked by AVG anti-virus system (http://www.grisoft.com).Version: 6.0.518 / Virus Database: 316 - Release Date: 11-09-2003

A stored procedure was created to update a database.
But, I don't know how to trigger it in code:
This is the example to create a dataset for Dropdownlist,
Dim da As New SqlDataAdapter(myCommand)
Dim ds AS DataSet = new DataSet() da.Fill(ds)
This way doesn't work for triggering the stored procedure for updating database
How to trigger the stored Procedure for updating the database in the code?
Thx.

Does anyone have code example on how to concatenate fields in a SQL Server stored procedure?
I would like to create a stored procedure to concat (off_name ' ' off_fname ' ' off_prior) to a field to bound to a combobox.
Thanks,

We have a static class that makes an HTTPWebRequest to get XML data from one of our vendors. We use this as input to a stored proc in SQLServer2005. When I compile this class and call it from a console application in visual studio it executes in milliseconds, everytime. When I compile it, create the assembly and clr function and execute it in SQLServer, it takes around 14 seconds to execute the first time, then on subsequent requests it is again really fast, until I wait for 10 seconds and re-execute, once again it is slow the first time and then fast on subsequent requests. We do not see this behavior when executing outside SQLServer. Makes me think that some sort of authentication is perhaps taking place the first time the function is run in SQLServer? I have no idea how to debug this further. Anyone seen this before or have any ideas?
Here is the class:
Code Snippet
using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.IO;
namespace Predict.Services
{
public static class Foo
{
public static string GetIntradayQuote(string symbol)
{
string returnQuote = "";
HttpWebRequest request = (HttpWebRequest)(WebRequest.Create("http://data.predict.com/predictws/detailed_quote.html?syms=" + symbol + "&fields=1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,28,30"));
request.Timeout = 1000;
HttpWebResponse response = (HttpWebResponse)(request.GetResponse());
StreamReader streamReader = new StreamReader(response.GetResponseStream());
returnQuote = streamReader.ReadToEnd();
streamReader.Close();
response.Close();
return returnQuote;
}
}
}
When I run call it from a console app it is fine.
I compile it into a dll and then create the assembly and function as follows:
Code Snippet
drop function fnTestGetIntradayQuoteXML_SJS
go
drop assembly TestGetIntradayQuoteXML_SJS
go
create ASSEMBLY TestGetIntradayQuoteXML_SJS from 'c:DataBackupsCLRLibrariesTestGetIntradayQuote_SJS.dll' WITH PERMISSION_SET = EXTERNAL_ACCESS
go
CREATE FUNCTION fnTestGetIntradayQuoteXML_SJS(@SymbolList nvarchar(max)) RETURNS nvarchar(max) AS EXTERNAL NAME TestGetIntradayQuoteXML_SJS.[Predict.Services.Foo].GetIntraDayQuote
go
declare @testing nvarchar(max)
set @testing = dbo.fnTestGetIntradayQuoteXML_SJS('goog')
print @testing
When I execute the function as above, again, really slow the first time, then fast on subsequent calls. Could there be something wrong with the code, or some headers that need to be set differently to operate from the CLR in SQLServer?
Regards,
Skipper.

Does anyone know how to pass a list of fields into a stored procedure and then use those fields in a select statement. Here's what I'm trying to do.
I have a front end application that allows the user to pick the fields they want return as a record set. Currently, all this is being done in the application. But, I'd like SQL to do it, if it's possible.
I'd pass the following into a stored procedure.
Set @Fields = "First, Last, ID" -- This is done in the application
Exec usp_return @Fields
Obviously, the following fails stored procedure doesn't work ...
CREATE PROCEDURE @FIELDS varchar(255) AS
SELECT @FIELDS FROM MY_TABLE
~~~~~~~~~~~~~~~
Any ideas?

I have some columns of data in SQL server that are of NVARCHAR(420)format but they are dates. The dates are in DD/MM/YY format. I want tobe able to convert them to our accounting system format which isYYYYMMDD. I know the format is strange but it will make things easierin the long run if all of the dates are the same when working betweenthe 2 different databases. Basically, I need to take a look at theyear portion (with a SUBSTRING function maybe) to see if it is greaterthan 50 (there will not be any dates that are less than 1950) and ifit is concatenate 19 with it (ex. 65 = 1965). Then, concatenate themonth and day from the rest to form the date we need in NUMERIC(8).So, a date of January 17, 2003 (currently in the format of 17/01/03)would become 20030117. In VB, the function I would write is somethinglike the following:/*Dim sCurrentDate as StringDim sMon as stringDim sDay as StringDim sYear as StringDim sNewDate as StringsCurrentDate = "17/01/03"sMon = Mid(sCurrentDate, 4, 2)sDay = Mid(sCurrentDate, 1, 2)sYear = Mid(sCurrentDate, 7, 2)If sYear < 50 ThensYear = "20" & sYearElseIf sYear > 50 ThensYear = "19" & sYearEnd ifsNewDate = sYear & sMon & sDay*/I was thinking of doing this in a Stored Procedure but am really rustywith SQL (it's been since college).The datatype would end up being NUMERIC(8). How I would write it if Inew how to write it would be: grab the column name prior to theprocedure, create a temp column, format the values, place them intothe temp column, delete the old column, and then rename the tempcolumn to the name of the column that I grabbed in the beginning ofthe procedure. Most likely this is the only way to do it but I have noidea how to go about it.

In the code sample below, case eLABEL, eENGUNITS works ok. The target SQL field is defined as varchar(50).
The second section is not so happy. It is attempting to write to an SQL field defined as binary(2)
Executing an SQL script to excercise this line results in error:
System.Data.SqlClient.SqlException: Incorrect syntax near the keyword 'foreign'
where 'foreign' is the name (FieldDef.sFldName) of the SQL field being written.
The c# code composes the following command:
"UPDATE " + acPointType + " SET " + FieldDef.sFldName +
" = @data_params WHERE VEC = '" + acVECName +
"' and name = '" + acPointName + "';";
What is the proper syntax for the second case set?

Hello,
I'm writing a fairly involved stored procedure. In this Stored Procedure, I have an update statement, followed by a select statement. The results of the select statement should be effected by the previous update statement, but its not. When the stored procedure is finish, the update statement seemed to have worked though, so it is working.
I suspect I need something, like a GO statement, but that doesnt seem to work for a stored procedure. Can anyone offer some assistance?

Is it possible to execute a stored procedure in one database, which thenitself executes a stored procedure from another database? We have decide tosplit our data into a tree structure (DB1) and data blobs (DB2) (we areusing MSDE and we have a 2gb limit with each DB so we've done it this wayfor that reason). I would like to, say, execute a stored procedure in DB1,passing in the data blob and other details, DB1 will create a tree node inDB1 and then add the blob record to DB2. DB1 will wrap in a transaction ofcourse, as will DB2 when it adds the blob. Is this possible?

Details :
Reporting Services 2000, SQL 2000 database, Visual Studio . Net 2003
In Report Design view
In "Data" tab, I can see records for column 'sRCName' returned from the stored procedure(usp_GetRouteCodeData) after clicking '!' icon. When I moved to "Preview" tab, I am getting below error message.
"The value expression for the textbox €˜sRCName€™ refers to the field €˜sRCName€™. Report item expressions can only refer to fields within the current data set scope or, if inside an aggregate, the specified data set scope."
Observation : there is no value returned from the dataset on 'Fields' panel. The SP is accessing a table called tblRCM.
If I go to the Data--> Dataset --> Query, change the "Command Type" from 'Stored Procedure' to 'Text' and entered
select * from tblRCM at Query string area, the report is running fine.
Issue: This issue only happens at my laptop, my team member can create the same report using the same stored procedure without any error. The database is sitting on a server.
In the troubleshooting process, I tried to create a simple report by calling a stored procedure(CustOrderHist) from NorthWind DB in my local SQL server, I am able to see the data/value in 'Fields' panel and sucessfully view the data in 'Preview' tab.
Looks like the issue only happen on my machine, for a report that using stored procedure to access a DB sitting on a server.
I hope to hear from anyone who have encountered the similiar issue before, or, have any clue to resolve the issue.
Thanks.

How can I grant permissions to a login to execute msdb.dbo.sp_update_schedule()? Or is there a way I can impersonate the sysadmin user for the call by using Execute As sysadmin some how?

My manager is interested in knowing if there is a way to update our website's SQL database using a method with excel, similar to importing.
The person who was previously in my position had imported a few hundred new products into the database with an excel spreadsheet.
Now, we would like to make updates such as a price changes or similar adjustments to a number of the products in the database. We could use a web interface, but ours requires us to find each product individually and it takes too much time. I told him that it would probably be necessary to write an SQL statement to update the tables, but we're also interested in maintaining the integrity of the database and are worried about loosing data due to a typo. Is it possible to export the db contents to an excel file, make changes, and then merge those changes into the existing database? I have tried and failed, so I am wondering if any experienced users could help me out.
Also, is there some kind of phpmyadmin for MS SQL? A free, open source alternative would be best.

Can someone walk me through the code for my update_command event?Every article I read and every tutorial I walk through has a slightly different way of doing this task.It's confusing trying to understand which code-behind variables I need in my update_command event and how to pass them to a stored procedure.
Please help me connect the dots.
I have a SQL server table that looks like this (Both data types are char)
Status_Id Status_DescriptionA ActiveP Planned
I have a SQL stored procedure that looks like this…
create procedure dbo.usp_Update_Status_Master(@status_id char(1),@status_description char(30))asupdate status_masterset status_description = @status_descriptionwhere status_id = @status_idGO
Here is my code behind…
Imports SystemImports System.DataImports System.Data.SqlClientImports System.ConfigurationImports System.Data.OdbcPublic Class WebForm1 Inherits System.Web.UI.Page Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load If Not IsPostBack Then Call LoadStatusMasterGrid() End If End Sub Public Sub LoadStatusMasterGrid() Dim connection As SqlConnection = New SqlConnection(ConfigurationSettings.AppSettings("sqlConn")) connection.Open() Try Dim command As SqlCommand = _ New SqlCommand("usp_Select_Status_Master", connection) Command.CommandType = CommandType.StoredProcedure Dim adapter As SqlDataAdapter = New SqlDataAdapter(Command) Dim table As DataTable = New DataTable adapter.Fill(table) dgStatusMaster.DataSource = table dgStatusMaster.DataKeyField = "status_id" dgStatusMaster.DataBind() Catch ex As Exception Console.WriteLine(ex.Message) Throw Finally connection.Close() End Try End Sub Private Sub dgStatusMaster_EditCommand(ByVal source As Object, _ ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles dgStatusMaster.EditCommand dgStatusMaster.EditItemIndex = e.Item.ItemIndex dgStatusMaster.DataBind() Call LoadStatusMasterGrid() End Sub Private Sub dgStatusMaster_CancelCommand(ByVal source As Object, _ ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles dgStatusMaster.CancelCommand dgStatusMaster.EditItemIndex = -1 Call LoadStatusMasterGrid() End Sub Private Sub dgStatusMaster_UpdateCommand(ByVal source As Object, _ ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles dgStatusMaster.UpdateCommand ‘ How do I code this part? End SubEnd Class
Thanks in advance for taking the time.Tim
