How to check if a table contains a specific number of rows?












0















I have this query: 



SELECT (COUNT(*) = SUM(status in (3, 5)) ) AS result 

FROM `match` WHERE round_id = 15


this essentially check if the table match have all the items with a status 3 or 5 for the round 15. This works, but I actually want add another condition, in particular if the result is true I want check that all the records of that table with round_id = 15 are 20. How can I perform this?






mysql sql

  • Based on the syntax, I added the mysql tag. If this is not correct, please add the correct tag for the database you are using.

Is this what you want?



SELECT (COUNT(*) = SUM(status in (3, 5)) AND COUNT(*) = 20) AS result 

FROM `match`

WHERE round_id = 15;


This checks that there are 20 rows that match the conditions.
