Can anyone give me a link to a complete example of a Named Update?

I don't know where to look for a named update, however it's pretty straightforward:
Create a method on your DomainService (says it's named MyCustUpdate)that return void and accept on input an instance of your entity (says it's named MyEntity)and, eventually, other parameters (primitives like int, string etc)
Decore this method with [Update(UsingCustomMethod = true)]
Client side, on the generated entity MyEntity you'll find the method MyCustUpdate; just call it and when you're done with your edits, call DomainContext.SubmitChanges
Your custom update method will be called as part of your SubmitChanges call server side

I want to create Elasticsearch query by myself and I looking for a package which will validate the query parameters (By the query type).
for example:
GET /_search?analyze_wildcard=true { //RANDOM BOD } - I'll get true
and for:
GET /_search?INVALID_PARAMETER=true { //RANDOM BOD } - I'll get false
Nice question, but As far as I remember there is no such package available but you can build one for yourself and it wouldn't be difficult to build one as you most probably don't need to validate all the query types.

In my app,I want to retrieve json data from api,but my json file is too complex and large.so I want specific data according to my app needs every time when I call api and save that data directly into sqlite database.
Then you need to only parse the data which you require, If you want to make this easy for you, use the extension in vs code, called DART DATA CLASS GENERATOR. It makes everything easy.
But, I would strongly suggest if you are new to the programming then learn DATA MODELLING.

I am fairly new to golang, and trying to identify the best tools for the job. Currently I am evaluating the following packages:
https://github.com/mattes/migrate
https://github.com/DavidHuie/gomigrate
https://bitbucket.org/liamstask/goose/
I was wondering if anyone had any experience with these (or other packages) and could provide some comments.
We use mattes/migrate at work and are very happy with it. It works with plain SQL files, handles file naming by itself and can easily be automated via CLI. It doesn't do anything Go specific.
With gomigrate you need to create the files yourself and write code for executing the migrations.
Take a look at https://github.com/pressly/goose, a maintained fork of https://bitbucket.org/liamstask/goose/.

I am designing an iPad App that needs a control that allows the user to create a tree-like nested structure visually similar to a class diagram designer or a ERD diagram designer.
Before I re-invent the wheel, has anyone come across any paid or open source controls that enable this type of functionality?
This is the basic use case: The user taps and creates an entity. The user taps the entity and selects an entity type and a sub entity is created with a link line between the sub entity and the super entity.
The following is what I found:

Does anyone have a good way of deleting duplicate transactions (same date, amount, biller, etc) in a QIF file? I looked at PERL's Finance:QIF, but it appear to have delete a record function.
Alternatively, does someone have a good QIF --> CSV converter?
Although I am looking at a PERL solution, I am open to other ideas.
Finance::QIF doesn't really need a delete() method (although it would be handy), because you can access all the transactions as a list and manipulate it yourself. The source code is very straightforward, it would be pretty easy to add a as_csv() method to Finance::QIF::Transaction (the module used to store one transaction's data), after which you can apply your own sort-for-uniqueness method (e.g. plain old "sort -u").
