By using the same mechanics, a SQL procedure can also define a result set and return it directly to the caller of the SQL procedure or to a client application. A cursor can be viewed as a pointer to one row in a set of rows. The cursor can only reference one row at a time, but can move to other rows of the result set as needed.

In order to encourage the use of its products, Sybase promoted the use of a flexible pair of libraries, called netlib and db-lib, to implement standard SQL. A further library was included in order to implement "Bulk Copy" called blk .
The SQL SELECT statement returns a result set of rows, from one or more tables. [1] [2] A SELECT statement retrieves zero or more rows from one or more database tables or database views. In most applications, SELECT is the most commonly used data manipulation language (DML) command.
Traffic classification is an automated process which categorises computer network traffic according to various parameters (for example, based on port number or protocol) into a number of traffic classes. [1] Each resulting traffic class can be treated differently in order to differentiate the service implied for the data generator or consumer.
Li et al. claimed that "our return indirection technique essentially de-generalizes return-oriented programming back to the old style of return-into-libc." [ 24 ] Their proof-of-concept compiler included a peephole optimization phase to deal with "certain machine instructions which happen to contain the return opcode in their opcodes or ...
A port scan or portscan is a process that sends client requests to a range of server port addresses on a host, with the goal of finding an active port; this is not a nefarious process in and of itself. [1] The majority of uses of a port scan are not attacks, but rather simple probes to determine services available on a remote machine.
