Please I need your help guys,

How do I create a query that will automatically add columns, Im not sure this will make sense. Example

I have a query that select name,surname and age from person table and now I want to add another field like phone number but I want my query to automatically detect that the is a field added so that I dont manually add fields all the time.

Is this possible and How do I go about?

Help me please.

The asterisk selects all columns in a table:

SQL

SELECT * FROM TheTable

If you are doing a JOIN between multiple tables, you can even specify which table to get columns from:

SQL

SELECT TheTable.* FROM TheTable
JOIN AnotherTable ON SomeValue = SomeOtherValue

There are also more advanced techniques, such as inspecting the system tables to see which columns a table has, then building a query as a string and executing it dynamically, but that is probably beyond what you are looking for at this time.
