Looking of tip on nested select statments

Question

Hi -- I am trying to count the distinct value of field in the table, but when processer get to this line and (b.emplid = z.emplid). It gives me error invalid table name.
I used the z as an alias for the selection...
would you please tell what I am doing wrong.tx
SELECT A.job, sum(decode(sex, 'M', 1, 0)) male_total, sum(decode(sex, 'F', 1, 0)) female_total
FROM DATA B,
(select distinct STDNT_EMPLOYEE A,
WHERE A.YEAR = '2008'
and a.status ='A') z,
and b.emplid = z.emplid
group by a.job

Answer 1

The Toad does not recognize my alias(z) as a table,
and it highlights it as table name error
SELECT A.job, sum(decode(L.sex, 'M', 1, 0))male_total,
sum(decode(L.sex, 'F', 1, 0)) female_total
from admin a, data L
(select distinct STDNT_EMPLOYEE x, from Hire Y
WHERE x.YEAR = '2008'
and a.status ='A') z,
where b.emplid = z.emplid
group by a.job
There's a multitude of basic typos in this code - for instance, the dangling comma in the subquery, the fact that x is a column alias and you use it as a table alias, the fact that there isn't a comma after data L...
STOP POSTING and start properly looking at your code.
