Hoping someone can help me figure why I'm getting a syntax error here. I'm counting all rows that have two distinct column values.
select count (*) as 'Distinct' from (
select distinct p.IDD, p.num
from PERF1 p
inner join MAST1 m
on (m.id_table = p.id_table and m.SOURCE_TABLE = p.SOURCE_TABLE)
where m.DATE > '2012-12-31' )
I'm getting an error on my last close bracket but can't for the life of me figure what I'm doing wrong here. ...............................
Kind of a huge "edit" but I'm a bit stuck. I thought that this query would count the number of distinct rows (for both columns) across this table. So for instance the count should return 6 since "P" and "T" are repeated. I thought I had it with this:
select count (*) as 'Distinct' from (
select distinct p.IDD, p.co
from PERF1 p
inner join MAST1 m
on (m.id_table = p.id_table and m.SOURCE = p.SOURCE)
where m.DATE > '2012-12-31' ) TempTable
but I'm getting a much higher number than I think I should so I'm hoping that my query is incorrect.
+------+------+
| IDD | CO |
+------+------+
| 11 | P |
| 12 | P |
| 13 | T |
| 14 | T |
| 15 | R |
| 16 | S |
| 17 | U |
| 18 | K |
You need to add a alias name for the subquery
select count (*) as 'Distinct' from (
select distinct p.IDD, p.num
from PERF1 p
inner join MAST1 m
on (m.id_table = p.id_table and m.SOURCE_TABLE = p.SOURCE_TABLE)
where m.DATE > '2012-12-31' ) TempTable
