Entity Framework 6 Recipes 2nd Edition (10-1) Translation-> returns an object set in non-Code Frist mode, recipesfrist Stored Procedure Stored Procedures exist in any type of relational database, such as Microsoft SQL Server. stored procedures are some code contained in the database. They usually perform some operations on the data. They can improve the performance of data-intensive computing and execute so

Just read the second chapter of CSS essence, mainly about the text style related to the operation of things.Although this book seems to be very rejected (no one on the watercress mark), and indeed the content is somewhat outdated, but I still feel that some of the basic things can be learned, CSS is relatively basic and practical things.The focus is on the text layout of link A, list ul, header line h, and basic element paragraph p. Pseudo-class definition of a element, underline List o

In particular traversal, the pointer executes only two additions at a

selection information, we have deleted the subject, then the relevant course and student selection information is not loaded by dbcontext, so EF cannot send the related entity flag as delete, and can not be sent to the database to delete related records of the command. However, if we define cascade deletions in the database, then the database itself will do a good job of cascade deletion.The best practice here is to define cascading delete rules in both the model and the database.If you add a c

Because the EF Design view does not su

We construct an esql expression to invoke our two "model definition" functions and project the results into the Name and the Age column. The result of our ESQL expression is a collection of anonymous types that contain the name and age members. Because we are not returning a type defined in the model, so we createqueryIn LINQ queries, we retriev

the LINQ query in EF5. you can view the execution result of listing 13-20 to see its improved performance. In addition, as shown in listing 13-20, you can also disable the "automatic compilation" feature. You can use the underlying object objectcontext of the dbcontext object to get a reference to an object, set its enableplancaching attribute to false. To track each compiled query, EF traverses the query expression Tree node, creates a hash table, and uses it as the index of the compiled query
