Question

I have to queries:

select id, name, num from pending    id, name, num 1, first, 1   3, third, 12   

select id, name, num from completed  id, name, num 1, first, 100 2, second, 20 

I want output to combine these, maybe like a pivot table, using T-SQL.

 id, name, pending, completed, total 1, first, 1, 100, 101 2, second, null, 20, 20 3, third, 12, null, 12 

How can this be written?

Answer 1

No need for a pivot.

SELECT     COALESCE(p.id, c.id),     COALESCE(p.name, c.name),     p.num AS pending,     c.num AS completed,     COALESCE (p.num, 0) + COALESCE (c.num, 0) AS total FROM     pending p     FULL OUTER JOIN     completed c ON p.id = c.id 

COALESCE is ANSI SQL but you could use ISNULL too
