View in SQL Server

I have made a table in SQL server, I added a few information and with New Query, I Tested this: :

Select * from Table-name

I could see the information that I have already inserted, when I make another I Added 3 tables and a few fields from them, and Execute! yet, I simply see the name of the fields and there is no information in the view. what should I do? Prior to this, done thorough research on View in SQL and went through some good Articles, to have a clear understanding of the topic here - https://www.scaler.com/topics/views-in-sql/

Any help would be much appreciated! Thanks

 

First, let’s clarify what a view is in SQL Server. A view is a virtual table that contains data from one or multiple underlying tables. It doesn’t hold any data itself but provides a way to query and present data as if it were coming from a single table.
Some possible reasons why your view might not be showing the expected data:

1. View Not Refreshed:
When you create a view, it captures the structure and data at that moment. If the underlying table(s) change (e.g., columns are added, reordered, or modified), the view won’t automatically reflect those changes.
To address this, you can refresh the view using the sp_refreshview system stored procedure. Execute the following command:

EXEC sp_refreshview 'YourViewName';

Replace 'YourViewName' with the actual name of your view.

2. Column Definitions Changed:

• If you alter the structure of the underlying table (e.g., added columns), the view might not recognize the new columns.
• Ensure that the view’s query includes the new columns you’ve added to the table.

3. Permissions and User Context:

• Verify that you’re querying the view with the same user context and permissions as when you created the view.
• Different users may see different data based on their access rights.

4. Unexpected Data Transformation:

• The view might be unexpectedly transforming the data. Check the view’s query for any transformations or filters.
• Make sure the view’s logic aligns with your expectations.

5. Wrong Database or Server:

• Ensure that you’re connected to the correct database and server. Sometimes, clients don’t explicitly show which database they’re connected to.
• Double-check the database context in your query.

6. Syntax Errors or Typos:
Review your view’s query for any syntax errors or typos. Even a small mistake can lead to unexpected results.

• If you suspect that the view needs refreshing, execute the sp_refreshview command.
• Verify that the view’s query includes the correct columns from the underlying tables.
• Double-check your user context and permissions.
• Examine the view’s query for any unexpected transformations or filters.
• Confirm that you’re connected to the right database.

Remember to replace 'YourViewName' with the actual name of your view.
