Ambigous Column Name In SQL Server TSQL Query

-
If you encounter this error in your TSQL query embedded in C#, you might want to check the table it is being joined. It might be that some field in the other table has the same fieldname.
Example
Orders - status varchar(90)
OrdersSubForm - status varchar(30)
Just make sure, you create a prefix of the table name plus the dot and append it in your field. Just like the example below, for the status field.
  Select   
   Orders.status,  
   OrderNum  
  from Orders  
  right outer join OrderSubForm  
  on OrderSubForm.ID = Orders.ID  
  where (your condition here)

Good day Gents! I was trying to update my Microsoft Teams status and was wondering if I can add or insert emoji. For editing or adding new teams status, only text fields are available and there's no emoji icon similar to writing a teams message. After googling for a few minutes, I found this link Emoji's in status which is a feature request in Microsoft Teams User's Voice Forum. So far this upgrade request only has thirty votes which is relatively small and may be considered a low priority for the product team to implement. Given the limitations at hand, I tried several approach including copying an emoji in a chat message which didn't work and later found a solution using Microsoft Outlook 365. First is to create a new email message in Microsoft Outlook and press (Window Key + .). The emoji dropdown control will appear. Next is to select the emoji that you wanted to add to Teams. Copy the emoji from the newly created email message template and paste that to Micr

Good afternoon fellow developers! I have been working with Bootstrap Modals before and it's time to demonstrate its significance using a simple ASP.NET MVC CRUD (Create Update Delete) application project using Entity Framework Database First approach.
