Question

Suppose I have a table foo with schema (name, age). So the table looks like:

NAME | AGE
John | 20
Jane | 50
Jason | 30

Now suppose I wanted to select from this table, but I wanted to change all their ages to 20 via the select query. That is, I don’t want to update the original table foo, but I want to select, something like:

SELECT name, 20 as age from foo

In other words, I want to manipulate the data on the select. Of course, my real-life example is much more complicated than this but knowing the answer to this will do. Thanks!

Answer 1

You basically just do what you put in your question:

SELECT name, newValue as age
from yourTable

This will give you the name from your table and then the value you specify for the other column.
