sql - How to move data between multiple database's table while maintaining foreign-key relationships/referential integrity? -


I am trying to figure out the best way to move / merge two tables of data from multiple databases.

I have a schema like the following: 

  Make the table product (Product ID inti recognition (1,1) No, name varchar (250) No, details Varchar ( 1000) False, image image with a foreign key of the image (image image identification (1,1) faucet, image data does not create image faucet) Create  image

ImageID Image '.

What is the best way to move data from multiple source databases into a destination database with a single schema in this table? My primary issue maintains links between products and their respective pictures. .

In SQL Server, you enable identification applicants: 

  Turn on SET IDENTITY_INSERT newtables & lt; Insert questions here & gt; SET IDENTITY_INSERT NewTable OFF

While privacy entry is enabled, you can insert a value in the Identity column like any other column. This allows you to copy the table, for example from a linked server: 

  into newdb.dbo. Select from NewTable * oldserver.olddb.dbo.OldTable

I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
