Question

I am trying to write a How much did I type? query on Stack* Data Explorer.

Modifying an existing query got me this far:

-- How much did I type?

DECLARE @UserId int = ##UserId##

  select sum(len(Body)) AS 'Posts' from posts where owneruserid = @UserId,
  select sum(len(Text)) AS 'Comments' from comments where userid = @UserId,
  (select sum(len(Body)) from posts where owneruserid = @UserId +
  select sum(len(Text)) from comments where userid = @UserId) AS 'Total'

I am expecting three columns and one row, something like this:

Posts    Comments    Total
1234     5678        6912

But there is some syntax problem, due to which I get:

Error: Incorrect syntax near ‘,’.
Incorrect syntax near ‘,’. Incorrect
syntax near the keyword ‘select’.
Incorrect syntax near ‘)’.

What is the correct syntax for this?

Here is a working query:

DECLARE @UserId int;
set @UserID = 4;  

Select *, (Posts+Comments) as Total
FROM
  (select sum(len(Body)) AS Posts    FROM posts    where owneruserid = @UserId ) p,
  (select sum(len(Text)) AS Comments FROM comments where userid      = @UserId ) c
