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!"

Then rename click Add toThe file appears in the project and opensThe second step is to add the modelDrag an
Some developers refuse to use the object relationship ing (ORM) technology because of their poor performance experience. Like any form of abstraction, using an ORM framework costs some additional overhead, but in fact, the performance of using properly tuned orm and handwritten native data access code is still quite good. More importantly, a good ORM framework is easier to tune and optimize performance, and it is much more difficult to tune the performance of handwritten native data access code.

This tool will help you calculate the possible permutations and combinations based on the maximum width and number of columns, and generate the corresponding PNG file so that you can drag it directly to the appropriate tool. More importantly, Grid.guide is completely free!
