I am trying to create a dynamic column in a table whose column name will be today's date and values will be populated based on a mathematical operation of an existing column. For example table, t1 has column a,b,c and I want to add a column called '04-26-2021' whose value will be a+b+c values. Does anyone know how we can implement it in Postgresql? Thanks

You are looking for a "view", an object that looks like a table, but is a query with a name. – Laurenz Albe Apr 27 '21 at 06:00

Why wouldn't you just call the column `today`? – Gordon Linoff Apr 27 '21 at 12:07

@IanKenney Thanks for the suggestion. But I am not storing date values in any column. I want to generate dynamically. – Nityanand wachche May 14 '21 at 06:22
