1. Traversing a stringThere is no iterative operation in SQL, so you can implement this process by connecting a table that is used as a traversal pointer.1 Selectsubstr (E.ename, Iter.pos,1) asC2 from(SelectEname fromEmpwhereEname= 'KING') E,3(SelectId asPos fromT10) ITER4 whereIter.posLength (e.ename);There are 10 data in T10, ID from 1-10.The FROM clause provides a Cartesian product, and the resulting table resemblesThe WHERE clause restricts the POS range. SQL

controller is used in the same way as a property. If you have loaded the sessioncomponent and the cookiecomponent in the controller, you can access them as follows: 1 class Postscontroller extends AppController {2 Publ IC $components = Array (' Session ', ' Cookie '); 3 4 Public Function Delete () {5 if ($this->post->delete ($this->request->data (' Post.id ') {6 $this->session->setflash (' Post deleted. '); 7 $this->redirect (' action ' = ' index ');

Application Identification Application Identifier;aidConsists of a registered application that provides a trademark (RID) and a dedicated application identifier extension (PIX) AID: Uniquely identifies an application, divided into two parts, RID (

The main functions of power management power supply inside the chip are described as follows: * Reset * Phase-locked loop and divider * HWCFG[2:0] PIN signal recognition and decoding * Sleep mode * Module Power Management * Top Level control

AbstractThe speed of Altera's EDA tools is very slow. This article proposes some suggestions to accelerate Altera tools. IntroductionThe whole product of Altera is slow in several places: 1. interval of us II.2. the timeout time of the niosii.3.

AbstractIf you connect us II and de2, this tutorial combination matches you. IntroductionThis is the tutorial used by the original tutorial of Altera for us II and de2. It is divided into two versions, namely the sparse and VHDL versions. You can

/* It should be a minimum point coverage problem. You can split the points and use a bipartite graph. Here we use the tree-like DP to solve the leaf node I. Obviously: DP [I] [0] = 0, DP [I] [1] = 1 otherwise, DP [I] [0] = sum (DP [J] [1], J is the

AbstractThe program of niosii is normal, but after reset, the program will not be moved. How can this problem be solved? Environment: US us II 7.2 SP1 + niosii 7.2 SP1 + de2 (Cyclone II ep2c35f627c6) IntroductionI used a program that runs on-chip

AbstractSometimes you have to write text or image in the program. Where should I put the case? You can use fopen () in the C-producer statement as long as you place your case in a zip file system without any other code () extract the statement.

The BQS24259 uses a nvdc (narrow-voltage DC) architecture that uses BATFET to separate the system from the battery, and the minimum systems voltage is set by reg01[3:1], even if the battery is completely depleted, and the system is set to the

Today, we work on the lab designed jointly by hardware and software. After the CPU is designed, we burn it into the Cyclone II chip of Altera and use the following simple C language:ProgramTest whether the CPU design is successful. 1 # Define
