What are Off-by-one bugs? Copying source string to destination buffer could result in off-by-one when Source string length is equal to destination buffer length. When source string length was equal to destination buffer length, a single NULL byte gets copied just above the destination Buffer. Here since the destination buffer are located in stacks, the single NULL byte could overwrite the least significant bit (LSB ) of caller's EBP stored in the stacks and this could leads

illustrates how the equivalence of the unknown and false predicate evaluations affects whether a subquery implementation can be used. Suppose where_condition contains only columns from T2 instead of T1, so that subqueries are irrelevant. This query may be implemented: 1.SELECT * FROM t1 2.WHERE t1.a IN (SELECT t2.b FROM t2 WHERE where_condition); The following restrictions apply to materialized using subqueries: The types of internal and external expressions must match. For example, i
