Create View using Stored Procedure dynamically

We can create view using stored procedure dynamically.

Please find my sample below:
I want to create a view name v_rpt + @Type and @Type as parameter. If the view already exists, it will be drop and recreate a new one.

We will need to execute @SQL twice

• execution 1: check whether the view exists, drop it if exists
• execution 2: create a new view

if we put both in the same query, it will hit error "'CREATE VIEW' must be the first statement in a query batch."


CREATE PROCEDURE [dbo].psp_Generate_view
(
@Type VARCHAR(255)
)
AS

BEGIN

SET NOCOUNT ON

DECLARE @SQL VARCHAR(8000)

SET @SQL = ''
SET @SQL = @SQL + 'IF EXISTS (SELECT * FROM dbo.sysobjects WHERE ID = OBJECT_ID(N''[dbo].[v_rpt' + CONVERT( VARCHAR, @Type) + ']'') AND OBJECTPROPERTY(id, N''IsView'') = 1) ' + char(13)
SET @SQL = @SQL + 'DROP VIEW [dbo].[v_rpt' + CONVERT( VARCHAR, @Type) + '] ' + char(13)

EXECUTE (@SQL)

SET @SQL = ''
SET @SQL = @SQL + 'CREATE VIEW dbo.v_rpt' + CONVERT( VARCHAR, @Type) + ' AS ' + char(13)
SET @SQL = @SQL + 'SELECT DISTINCT '
SET @SQL = @SQL + 's.SKUNo, '
SET @SQL = @SQL + 's.Model, '
SET @SQL = @SQL + 'lk1.LookupDesc [Region], '
SET @SQL = @SQL + 'lk2.LookupDesc [Country], '
SET @SQL = @SQL + 'CASE s.Status '
SET @SQL = @SQL + ' WHEN 1 THEN ''Saved'' '
SET @SQL = @SQL + ' WHEN 2 THEN ''Rejected'''
SET @SQL = @SQL + ' WHEN 3 THEN ''Approved'''
SET @SQL = @SQL + 'END AS Status, '
SET @SQL = @SQL + 's.Remark, '
SET @SQL = @SQL + 'u1.FullName [Creator], '
SET @SQL = @SQL + 's.CreDte [Date of Creation], '
SET @SQL = @SQL + 'u2.FullName [UpdatedBy], '
SET @SQL = @SQL + 's.LastUpdDte [Updated On], '
SET @SQL = @SQL + 'FROM tblSKU s '
SET @SQL = @SQL + 'LEFT OUTER JOIN tblUser u1 ON s.OwnerID = u1.UserID '
SET @SQL = @SQL + 'LEFT OUTER JOIN tblUser u2 ON s.LastUserID = u2.UserID '
SET @SQL = @SQL + 'LEFT OUTER JOIN tblLookup lk1 ON s.Region = lk1.RefIdn AND lk1.GroupIdn = 1 '
SET @SQL = @SQL + 'LEFT OUTER JOIN tblLookup lk2 ON s.CTY = lk2.RefIdn AND lk2.GroupIdn = 2 '
SET @SQL = @SQL + 'WHERE '
SET @SQL = @SQL + 's.Type= ' + CONVERT( VARCHAR, @Type) + ' AND '

EXECUTE (@SQL)


SET NOCOUNT OFF
END

The worst wireless modem router that have ever used

Trust me, don't go to get Aztech modem. You will regrets if you have one.

Aztech DSL600EW ADSL2/2+ Ready Wireless LAN 802.11g is the worst modem that i ever had. The wireless line simply disconnected and need to restart the router, the ADSL frequently disconnected with the service provider, the stupid un-userfriendly interface (even a simple port forwarding takes me hour to configure and yet cannot be done). I bet you will definately throw it out from your house or office.

VBScript: Open new windows (IE)

To open new window using client side vbscript,
use open "url", "target", "options"

example:

Sub fnOpenUrl(url)

open url ,"newWindow", "toolbar=no, menubar=no, status=no, width=830, height=660 titlebar=no, scrollbars=yes, resizable=yes, top=5, left=5 "

End Sub

to call the function

fnOpenUrl("http://www.xincrm.com")

Done.

DefaultButton for ImageButton not working in firefox

Well, read this article first before finding other solution http://support.microsoft.com/kb/921277

I've been trying to look around and work on the code but it's not working. Don't waste your time for simple problem unless you have plenty of them.

The easiest way is change the ImageButton control to Button control as stated in the article. Put in some css will give the same effect/result in term of display like in ImageButton.

Below is the css that i use for this purposes.

.buttoncss
{
width:98px;
height:43px;
background-color:#FFFFFF;
background-image:url(http://xincrm.com/img/Button.gif);
border-style:none;
cursor:pointer;
}

Try this http://www.pagetutor.com/button_designer/index.html if you want to customize your button css. Very useful for me.

Remember set UseSubmitBehavior for Button control to False in Properties window.

UseSubmitBehavior="False"


it's work for me. My problem solved.

2. Folder permission - set the correct permission. In my case, i allow write permission for internet user (IUSR_xxxxx).

Problem solved.

Manage/Delete IIS log files using scheduler

Microsoft have provide a very good resource kits. Forfiles is one the them that we can use to manage our log files especially IIS log. My purpose for this article is to show how i use forfiles to help me to manage/delete my IIS log file more than 14 days (you can delete any time frame you want).

Steps:
1. download and install Windows Server 2003 Resource Kit Tools
2. write a bat script
3. create a scheduler


Let look at the details

1. download and install Windows Server 2003 Resource Kit Tools

In order to us it, you need to install it in your server first. Go to microsoft website "Windows Server 2003 Resource Kit Tools" and download it. After finish downloading, you can start to install it.
After finish installation, you can find Forfiles in C:\WINDOWS\system32\forfiles.exe


2. write a bat script

Syntax for forfiles

forfiles [/p Path] [/m SearchMask] [/s] [/c Command] [/d[{+ -}] [{MM/DD/YYYY DD}]]

the details syntax you can get it from technet.

For me, i want to delete the log files date 14 days before. Below are some of the details

1. log file location = C:\WINDOWS\system32\LogFiles\W3SVC1
2. file type = *.log
3. Date to delete = -d -14 (14 days before)

Below is the command that i'm able to come out and save it as .bat format. Say, "managelog.bat"

Forfiles -p C:\WINDOWS\system32\LogFiles\W3SVC1 -s -m *.log -d -14 -c "Cmd /C DEL @File"

copy forfiles.exe from C:\WINDOWS\system32\forfiles.exe and managelog.bat to the same location which you prefer.

3. create a scheduler

You need to create a scheduler to run the job automatically. For me, i run my job weekly at mid night 12:30AM.

To know how to create a window scheduler job, please find reference here.

Please test it before make it run automatically. I suggest that you use below command line to test. I change the DEL to ECHO so that i work safely.

Forfiles -p C:\WINDOWS\system32\LogFiles\W3SVC1 -s -m *.log -d -14 -c "Cmd /C ECHO @File"

Done. Good luck.

CS0101: The namespace '<global namespace>' already contains a definition for 'xxxxx'

Server Error in '/' Application.

Compilation Error
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS0101: The namespace '<global namespace>' already contains a definition for 'xxxx'



check whether you have a copy of the file with different name but using the same class (duplicate file). In My case, i have a backup copy for a aspx file. Delete the file or exclude from the project will solve the problem.

Ping an IP through a specific port in cmd prompt or telnet

Well, sometimes we need to know whether the port in open or block, we need to do some checking or troubleshoot through ping/telnet. We cannot ping a IP with port but we can telnet certain IP together with Port no.

For example:
Go to open command prompt, if we want to check whether port 21 is working for IP 203.166.87.9 what we need to do is
> telnet 203.166.87.9 21

please tell me it's work. thanks
