SQL wm_concat function
Question: I have a table test_test and I need to count the
distinct mark columns and them display all matching values
on one line:
Name Mark
------- ------
ABC 10
DEF 10
GHI 10
JKL 20
MNO 20
PQR 30
The result should be like this, with the count and the rows
groups onto the same line;
mark count names
---- ----- -----------
10 3 ABC,DEF,GHI
20 2 JKL,MNO
30 1 PQR
Answer: By Laurent Schneider: You could write your own
aggregate function or use WM_CONCAT:
select
mark,
count(*),
wm_concat(name)
from
test_test
group by
mark;
Here is another example of using wm_contcat:
select
deptno,
wm_concat(distinct ename)
from
emp
group by
deptno;
DEPTNO WM_CONCAT(DISTINCTENAME)
