Suppose i have 1kk records in my database.
Now i need to select some data, and also i need to know how many fields did i select, so my question is:
Is it better to run one query to count data like this:
SELECT COUNT("id") from table where something = 'something'
And after that run one more querio for selection like this:
SELECT 'some_field' from table where something = 'something';
Or Maybe it's better to just select data and then just count it with php like:
count($rows);
Or maybe there is even better ways to do it, for example do it all in one query?
