lightspeed vs square

Please visit http://www.mindscape.co.nz/Products/LightSpeed/whylightspeed.aspx Lightspeed when CES the code you need to writeLightspeed was designed to make writing software easier, faster and more enjoyable. There is minimal impact on your domain model classes and no need to write bulky XML Mapping Files. Lightspeed is all about being fast.

1.UpdateFor bulk operations, either update or remove is done using the Lightspeed query object.Note: Student is the table (entity) to be update, Stuname is the one used in table student for queryingvar stuquery = new Query ( typeof (Student), entity.attribute ("stuname") = = "Lao Wang");This query object is equivalent to a where. The specific SET statement is implemented in the code below.New );The age of student, Stuname equals "Lao Wang", is

When you use Lightspeed to perform a LEFT JOIN or right JOIN operation on a database, you often report strange exceptions.Clearly the table is not a problem, the surface of the statement is not a problem, can always error. Look at the SQL in the parser, it is lightspeed to the left right join parsing is problematic.Note: LS to the LEFT join and right join will finally parse into group Join to handleOf cours

While using the query provided by Lightspeed can solve most of the problems, if the business logic is too complex, it is sometimes necessary to execute SQL statements or stored proceduresThe way to use SQL is by using Findbysql.The Findbysql parameter has only one Command.And the way to create a command is not that simple.var cmd = UnitOfWork.Context.DataProviderObjectFactory.CreateCommand ();Command needs to be given text, and there may be parameters

LightSpeed is a high-performance. NET domain modeling and O/R mapping framework, the first level of LINQ support, Visual Studio 2008/2010 Designer integration, is a well-known high-performance framework. " Note: fees are charged!"

Magic Square is divided into Class 3 . Odd Order magic square (odd), double even magic square (can be divisible by 4, such as 8,12,16 ...). ), the single magic square (4m+2 form, such as 6,10 ... ), the construction algorithm is different. In the following program, the algorithm for constructing odd-order magic squa

A function mathematically can have an infinite number of function columns converge to this function, then the program approximation implementation can have countless kinds of algorithms, square root nature is no exception.Do not know how many people still remember the square root of the hand, it is to satisfy each time in the result of adding a bit, that is, the bitwise approximation of the results of the o

[Leetcode] 221 Maximal Square (Daquan 1 Square Dynamic Planning) When we determine the largest square in the lower right corner of a square, the top three points, left and top left, must be the bottom right corner of a square, otherwise, the largest

In the course of my research on the technology of Ethernet square, due to the relatively few data, it took a lot of detours. So here we will not first introduce the grammatical structure of solidity, but will be in the next phase, from the actual combat, to introduce you to Geth, browser-solidity, mist these three tools, and in the process of constantly explaining the basic concept of the ether. Through the actual use of these tools, as well as the ba

In the day-to-day office work, we may have to use the square meters, although we will write, but may not play oh, in fact, a variety of input methods and Word have this symbol, the bottom let small to tell you how to enter the square meter symbol bar. How do I enter the square meter symbol? square meters How to hit t

Given a positive integer num, write a function which returns True if num is a perfect square else False.Note: do not use any built-in library function such as sqrt .Example 1:Input:16returns:trueExample 2:Input:14returns:falseCredits:Special thanks to @elmirap for adding this problem and creating all test cases.This problem gives us a number, let us determine whether it is a complete square number, then it

setting up a private chain environment based on Ethernet square Through the methods and scripts in this article, we can quickly build their own private chain for block chain development test, this article based on the Ethernet workshop technology to build, divided into two parts, one is the Ubuntu under the building method, the other is windwos under the construction method, One, install Geth client under Ubuntu Ubuntu is used because the official si

Latin Square, Latin Square The Latin square matrix is a matrix of n × n. There are EXACTLY n different elements in the square matrix, each of which has n elements, and each element exactly appears in one row and one column. The famous mathematician and physicist Euler used Latin letters as symbols of elements in the La

There is a formula in chemistry and mathematics that is often used by many people, and that is the square root. Many friends in the use of Word will not enter the "root", indeed this is a difficult problem, this humble little symbol once baffled many people. Some people even think that there is no such symbol in Word! In fact, it is more complicated to enter this method in Word! Plus it's not very common, so it's often overlooked by many people! Today
