After reading the specific SQL statements, you will understand the statements here. KillerNow that we have a tree, we can use the tree function sys_connect_by_path and connect by to splice the required multi-column values. The script is as follows:Select No, sys_connect_by_path (Q ,',')From (Select No, Q,No + row_number () o

volumes of B and A to R respectively. The total shear volumes are the total shear volumes of R. Expressed: R = g * m21 + B * m31 + A * M41; G = r * m12 + B * M32 + A * M42; B = r * M13 + G * M23 + A * m43; A = r * m14 + G * M24 + B * m34; 3. Color rotation: The description of color rotation is complex, that is, in the image pixel, two of them are used to calculate the result around the other one according to a certain angle, is the color rotation.

requires three main components: the combination logic that computes the function that operates on the bit, the memory element that stores the bits, and the clock signal that controls the update of the memory element. And, or, not three kinds of logic gates can be implemented with a gate (with a non-gate, or not gate). Multiplexer. The multiplexer selects one from a different set of data signals based o

With the advent of IO multiplexing technology, there are many event processing modes. The synchronous I/O model is typically implemented by the reactor pattern, while the asynchronous I/O model is implemented by the proactor pattern. Reactor mode: As shown above, the reactor mode is also called a reactor or reactor, the processor that implements the registration descriptor (HANDLE) and the event (EventHandler), and when an event occurs, the event Reator Demultiplexer) responds by i

compatible.SATA II is developed on the basis of SATA, and its main feature is that the external transfer rate is further increased from 1.5G SATA to 3G, including NCQ (Native command Queuing, native commands queue), Port multiplexer (ports Multiplier), staggered start (staggered spin-up) and a series of technical features. Pure external transfer rate of 3Gbps is not true SATA II.The key technology of SATA II is the external transfer rate and NCQ tech

-bit bus width, byte, half byte, and word transmission support. The AHB system consists of a master module, a module and an infrastructure (Infrastructure) 3 part, the transmission of the entire AHB bus is issued by the main module, from the module responsible for response. The infrastructure consists of an arbiter (arbiter), a master module, a multiplexer from a module, a multiplexer from a module to a mas

source .For PS streams, each PES header contains pts and DTS, stream identification codes , which are used to differentiate es in different properties. the PES package is then re-used into PS package via PS multiplexer . The fact is that the PES package is decomposed into a smaller PS package .at the time of decoding, the multiplexer decomposes PS into a PES package, unpacking and then splitting the PES pa
