Problem

There are data gaps that need to be filled, possibly using PARTITION BY.

Query Statement

The select statement reads as follows:

SELECT
  count( r.incident_id ) AS incident_tally,
  r.severity_cd,
  r.incident_typ_cd
FROM
  report_vw r
GROUP BY
  r.severity_cd, r.incident_typ_cd
ORDER BY
  r.severity_cd,
  r.incident_typ_cd

Code Tables

The severity codes and incident type codes are from:

• severity_vw
• incident_type_vw

Actual Result Data

36  0   ENVIRONMENT
1   1   DISASTER
27  1   ENVIRONMENT
4   2   SAFETY
1   3   SAFETY

Required Result Data

36  0   ENVIRONMENT
0   0   DISASTER
0   0   SAFETY
27  1   ENVIRONMENT
0   1   DISASTER
0   1   SAFETY
0   2   ENVIRONMENT
0   2   DISASTER
4   2   SAFETY
0   3   ENVIRONMENT
0   3   DISASTER
1   3   SAFETY

Any ideas how to use PARTITION BY (or JOINs) to fill in the zero counts?
