…ount on index (apache#41375) ## Proposed changes ``` select count(b) from table where b = 30 or c = 20; ``` - we should read column b - Rules for count on index: count is limited to types like count(*) and count(b), and in the query conditions, only count columns are connected using OR. - If the query conditions connected by OR include other columns, then it is not a count on index. - `select count(b) from table where b = 30 or c = 20;` is not a count on index, but `select count(b) from table where b = 30 or b > 200; ` is a count on index.
