This commit add a new plan node named AssertNumRowsNode
which is used to determine whether the number of rows exceeds the limit.
The subquery in Binary predicate and Between-and predicate should be added a AssertNumRowsNode
which is used to determine whether the number of rows in subquery is more than 1.
If the number of rows in subquery is more than 1, the query will be cancelled.
For example:
There are 4 rows in table t1.
Query: select c1 from t1 where c1=(select c2 from t1);
Result: ERROR 1064 (HY000): Expected no more than 1 to be returned by expression select c2 from t1
