MySQL Query: Displaying counts for many groups with many records

Question

I need to produce a large HTML table with quarterly counts for several (around 50) different groups (jurisdictions). I have a MySQL table with around 16,000 rows which have 'jurisdiction_id' and 'quarter' fields. Unfortunately my client doesn't want the resulting report to be paginated. How would I construct a good MySQL query from which to generate such a table with PHP and HTML? Please see the image for the desired end-result.

Table Name: inspections

Relevant Table Fields:

• id
• jurisdiction_id
• quarter

I'm a SQL newb, so please let me know if you need more information in order to provide a helpful response.

Thank you so much for your help.

Answer 1

Something like this should be fine:

SELECT jurasdiction_id, quarter, COUNT(*) AS num
FROM inspections
GROUP BY jurasdiction_id, quarter
