Remove all spaces from strings using sql

I wanted to remove following spaces and special characters from these strings;

'a. Personnel '
'j.  Indirect Charges '

I tried to use following SQL to get rid of all spaces;

SELECT DISTINCT TRIM(LOWER(REPLACE(BudgetCategories, ' ', ''))) BudgetCategories
FROM [dbo].[MyTable]

Still the trailing spaces were there. I guess there is a special character involved, so i tried this one;

SELECT DISTINCT LTRIM(RTRIM(LOWER((REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(BudgetCategories, ' ', ''), CHAR(10), CHAR(32)),CHAR(13), CHAR(32)),CHAR(160), CHAR(32)),CHAR(9),CHAR(32))))))
FROM [dbo].[MyTable]

This did the trick and I was able to get this output;

'a.personnel'
'j.indirectcharges'

SQL Server Transaction block

This is suggested code block for creating stored procedures in SQL Server;

BEGIN TRY
	BEGIN TRANSACTION
	--All your insert/update/delete/merge goes in here
	COMMIT TRANSACTION
END TRY

BEGIN CATCH
	SELECT ERROR_NUMBER() AS ErrorNumber
	,ERROR_MESSAGE() AS ErrorMessage
	 ROLLBACK TRANSACTION
END CATCH

While manipulating multiple tables, the transaction would be roll back if there is any error.

SSIS Foreach Loop Folder as variable

I need to set the Folder in Foreach loop to a variable location. I tried just adding the location to my package configuration, and it worked.

To make Folder dynamic so that it can get values from variable, Create a variable;

Click on Expressions under Foreach Loop Editor

This setting will take precedence to the folder value in Folder text box. Optionally you can set the FileSpec to a user variable pointing to the files (which will take precedence to the Files in Files text box.

How to create midnight datetime

Midnight is the first one – It’s the very first second of the day, not the last.

var todayDateTime = DateTime.Today;
var Midnight = todayDateTime.AddSeconds(-1);
//Here are the results
Console.WriteLine($"Today {todayDateTime.ToString()}, Mid night {Midnight.ToString()}");

The output is this;

Today 10/8/2021 12:00:00 AM, Mid night 10/7/2021 11:59:59 PM
