TSQL : Strip Special characters from string

Here is how you can strip all special characters from a column. Here I need to remove all special characters from a column before inserting into database. I wrote this function to reuse this in different places.

CREATE FUNCTION dbo.usfStripSpecailCharacters
@str VARCHAR(255)

WHILE PATINDEX( '%[~,@,#,$,%,&,*,(,),.,]%', @str ) > 0
SET @str = Replace(REPLACE( @str,
SUBSTRING( @str, PATINDEX( '%[~,@,#,$,%,&,*,(,),.,]%', @str ), 1 ),''),'-','')

-- Use this function and pass your string to remove special characters
SELECT dbo.usfStripSpecailCharacters('test#se3#$%#@-32402');
Hope this is useful!!

TSQL: Time in Military Format in 00:00 or 0000 format

Here is a way you can get time in desired military format. I need this to be in 0000 format.

For example If the current time is 12:35 AM, I need to be display this in 1235 in integer format or if you want with 12:35 you can use the following to fulfill your requirement.

id INT IDENTITY(1, 1),

VALUES ('7:34:00 PM')

FROM @time
-- time without colon in military format
SELECT REPLACE(CONVERT(VARCHAR(5), dt, 114),':','') AS FormatedDT
FROM @time

Missing Send to items in windows 7

Recently I lost few of my icons went missing from Send to folder when we right click on any item or folder. I frequently use Mail Recipient in this. Here is how we can restore this back from default profile

1. Go to following path for default profile setting to capture

"C:\Users\Default\AppData\Roaming\Microsoft\Windows\SendTo" or any other profiles which you have access to from below locations

2. Now go to run command  or type in start-search box and type shell:sendto to access your own profile.

3. Copy missing files from your default profile to your own profile. If you want you can add  your own short cuts for quick access.

You are good to go now. Hope this helps!!
