In this talk, we will discuss the low level foundations of what a raw pointer is--a variable that stores an address. We will then see some examples of raw pointers for creating data structures, passing pointer is a variable that stores the memory address of a specific object type ○ (Let’s look at an example) 13What is a Pointer? (2/8) ● A pointer is a variable that stores the memory address of a 14 ● px is a pointer ● px’s type is int* ○ px can stores addresses of integers.What is a Pointer?

@YangKeao When the application code retrieves the result set using Cursor Fetch, TiDB usually first stores the complete result set in memory, and then returns the data to the client in batches. If the result schema is defined by the SELECT statement that creates the view. • Sequence: a sequence generates and stores sequential data. • Temporary table: a table whose data is not persistent. 4.5.1.2 Access Control as a literal quantity in TiDB, independent of the time zone. On the other hand, the TIMESTAMP type stores a timestamp and thus displays a different time string in a different time zone. Note: Like MySQL
