阅读更多关于 Generate JPA 2 Entities from existing Database

How can I generate JPA2 compliant @Entity from existing Databases?. I found this: Question Still its not clear if JBoss will generate compliant JPA2 and also I would like to know if there is a vendor independent way to do this. You can use a plugin like Eclipse Dali to do the trick for you. You can refer to the documentation, section 3.11 Generating Entities from Tables . I do not know of any specific vendor independent tool to do this, though. Try using OPENJPA Reverse mapping tools. They offer lot more facility and are easy to configure. This example would clarify.

Generate Delete Statement From Foreign Key Relationships in SQL 2008?

阅读更多关于 Generate Delete Statement From Foreign Key Relationships in SQL 2008?

Is it possible via script/tool to generate a delete statement based on the tables fk relations. i.e. I have the table: DelMe(ID) and there are 30 tables with fk references to its ID that I need to delete first, is there some tool/script that I can run that will generate the 30 delete statements based on the FK relations for me ?

How do I generate a constructor from class fields using Visual Studio (and/or ReSharper)?

阅读更多关于 How do I generate a constructor from class fields using Visual Studio (and/or ReSharper)?

I've gotten accustomed to many of the Java IDEs ( Eclipse , NetBeans , and IntelliJ IDEA ) providing you with a command to generate a default constructor for a class based on the fields in the class. For example: public class Example { public decimal MyNumber { get; set; } public string Description { get; set; } public int SomeInteger { get; set; } // ↓↓↓ This is what I want generated ↓↓↓ public Example(decimal myNumber, string description, int someInteger) { MyNumber = myNumber; Description = description; SomeInteger = someInteger; } } Having a constructor populate all of the fields of an

阅读更多关于 return only Digits 0-9 from a String

I need a regular expression that I can use in VBScript and .NET that will return only the numbers that are found in a string. For Example any of the following "strings" should return only 1231231234 123 123 1234 (123) 123-1234 123-123-1234 (123)123-1234 123.123.1234 123 123 1234 1 2 3 1 2 3 1 2 3 4 This will be used in an email parser to find telephone numbers that customers may provide in the email and do a database search. I may have missed a similar regex but I did search on regexlib.com. [EDIT] - Added code generated by RegexBuddy after setting up musicfreak's answer VBScript Code Dim

Generate POCO classes in different project to the project with Entity Framework model

阅读更多关于 Generate POCO classes in different project to the project with Entity Framework model

I'm trying to use the Repository Pattern with EF4 using VS2010. To this end I am using POCO code generation by right clicking on the entity model designer and clicking Add code generation item. I then select the POCO template and get my classes. What I would like to be able to do is have my solution structured into separate projects for Entity (POCO) classes and another project for the entity model and repository code. This means that my MVC project could use the POCO classes for strongly typed views etc and not have to know about the repository or have to have a reference to it. To plug it

Formatting Literal parameters of a C# code snippet

阅读更多关于 Formatting Literal parameters of a C# code snippet

问题 Is there any way that I can change how a Literal of a code snippet renders when it is used in the code that the snippet generates?
