选择*从表中，同时获取列名称作为mysql中的别名

Question

I would like to select all the columns in a table but one of the columns should be modified and have an alias. Is there any better way to do this rather than writing all the column names and setting alias to the required one. Like

SELECT
    *,
    date_format(a.date,'%m-%d-%y') AS formatDate
FROM
    myTable a
WHERE
    Id = 1;

Answer 1

I found a way to make this work. We can select all and change the name of column(s) to alias.

Let's say we have a table activity with following columns where startTime stores the timestamp with date and time and we need a coulmn that just gives us the date.

sl.No  startTime  endTime  timeCreated

We can use this query

SELECT *, date_format(startTime, '%m-%d-%Y') as startDate FROM activity which gives us.

sl.No startTime endTime timeCreated startDate

This will give us an extra column compared to the original table, but we don't have to list all the columns manually to set alias for just one column.
