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

Drop orphan users – internal.object.permissions

I did a database restore from development to staging. Couldn’t connect to database using user login, Adam. Selected General tab on properties by clicking on Database->Security->User->Adam. The User type is “SQL user without login”. It seems restore process didn’t connect to the logins.

I try to drop the user;

DROP USER [qsadb]

I keep getting this error;

  • Msg 208, Level 16, State 1, Procedure ddl_cleanup_object_permissions, Line 8 [Batch Start Line 2]
  • Invalid object name ‘internal.object_permissions’.

So, this is an orphan user and issue is with permissions. This needs to be fixed. But how?

Here are the steps that I have used;

The problem is that the user in the database is an “orphan”. This means that there is no login id or password associated with the user. This is true even if there is a login id that matches the user, since there is a GUID (called a SID in Microsoft-language) that has to match as well.

This used to be a pain to fix, but currently (SQL Server 2000, SP3 and up) there is a stored procedure that does the heavy lifting.

All of these instructions should be done as a database admin, with the restored database selected.

First, make sure that this is the problem. This will lists the orphaned users:

EXEC sp_change_users_login 'Report'

If you already have a login id and password for this user, fix it by doing:

EXEC sp_change_users_login 'AUTO_FIX', 'user'

If you want to create a new login id and password for this user, fix it by doing:

EXEC sp_change_users_login 'AUTO_FIX', 'user', 'login', 'password'

jQuery Ajax – tips

jQuery Ajax is async by nature. We use to set a flag “async:false” if we need to make Ajax call sync (non-blocking). This feature has been deprecated. Here is a compile list of Ajax using jQuery;
