An alias is created with the as keyword.
If i'm using as, is there an option to not return the original column name
The default behavior appears to return both the original and the new column. It provides a way to rename the tables or columns temporarily, making the output more readable and intuitive. One way to achieve this is by using custom column names in sql Column aliases are used to rename the column in an output from a mysql query
This is helpful when column names are too long, not descriptive enough, or when working with calculated fields and aggregate functions. It may be better to return the aliases from the sql code, and have the client to do the presentational mapping The below certainly sorts under the section advanced.

Should you use 'name' or 'user name'
Read more to find out! There is no correct way, it's just a matter of taste I'd use the prefix over the postfix because it puts the more meaningful part of the name first, making it slightly faster to read (or so i imagine) Using id is a sql antipattern and should not be used.
I use user ids a lot in tables, and i would like to find out when naming these columns, what's the best way to go about naming them Should you be specific to what the user id is, or should you keep using the same column name (s) to keep it consistent? Aliases are used to give a table, or a column in a table, a temporary name
