select s.entry_id, sum(case when p.no_eli_educ > 0
then case when name_of_schools = 'no facility' then 1 else 0 end
else 0
end)
from schools s
inner join payroll p on s.entry_id = p.entry_id
group by s.entry_id

update payroll set number_of_no_schools

"query here"

where p.no_eli_educ > 0

thanks!

For MySQL 5.0, this would not be the right forum to ask the question. This is a Microsoft SQL Server forum.

Regardless, what you would need is something like this (although I don't think MySQL supports the common table expression quite in the same way). Also, if you have multiple rows in the payroll table for a given entry_id, this may not (or may) be the right query:

;with cte as
(select s.entry_id, sum(case when p.no_eli_educ > 0
then case when name_of_schools = 'no facility' then 1 else 0 end
else 0
end) as no_schools
from schools s
inner join payroll p on s.entry_id = p.entry_id
group by s.entry_id
)
update p set 
	p.number_of_no_schools = c.no_schools
from
	payroll p
	inner join cte c on c.entry_id = p.entry_id
