How do I select all the columns from a table, plus additional columns like ROWNUM?

Question

In Oracle, it\'s possible to do a SELECT statement that returns the row number as a column in your result set.

For example,

SELECT rownu         


        

Answer 1

Qualify the * with the name of the table:

select rownum, table.* from table

Answer 2

Unfortuantely, i dont think therei s a way to do it, easiest is probably inner join with itself with an inline table of id,count(*), and put an outer select statement

Answer 3

Dave's answer is great, i'd just like to add that it's also possible to do that by placing the wildcard as the first column:

select *,rownum from table

Works, but the following won't:

select rownum,* from table

I've tested on MySQL.
