To count the number of records for each id_market where id_data_provider is 'asda_quantium_uk', you can use the GROUP BY clause along with the COUNT function in SQL.
Example
SELECT id_market, COUNT(1) AS cntFROM adri_factWHERE id_data_provider = 'asda_quantium_uk'GROUP BY id_market;This query groups the records by id_market and counts the number of records in each group where id_data_provider is 'asda_quantium_uk'.
Important Considerations
COUNT(1): This counts all rows where the condition is met. It is equivalent to COUNT(*).
GROUP BY: This clause groups rows that have the same values into summary rows.
Alternative Solutions
COUNT(*): You can use COUNT(*) instead of COUNT(1) as they are functionally equivalent.
HAVING Clause: If you need to filter groups based on a condition, you can use the HAVING clause.
