How to insert column name of one table to row of another table with some added property

Suppose i have a table A with columns :

| Name | IsNUllable  | Datatype |

And another table B

 | id | Stock | Power

i want to make an entry to a table A by taking the column Name of Table B and adding property to it
example:

| Name | IsNUllable  | Datatype |
|  id  |  False      | int      |
|Stock |  False      | float    |
|power |  False      | nvarchar |

 

>Solution :

There is no need to store this information, it’s already available in the sys objects. You can easily get this with a query like below:

SELECT c.[name],
       c.is_nullable,
       t.[name] AS Datatype
FROM sys.columns c
     JOIN sys.types t ON c.user_type_id = t.user_type_id
WHERE c.object_id = OBJECT_ID(N'dbo.YourTable');
