Updating data with linq Adult texting hookup
But what if I have ten same id's in my table and I want to update (or delete) them all at once? Thank you for your advice on Delete, it works:) However I'm still trying to figure out how to use the foreach for updates.
So if I wanted to update for example phone number, name and address based on the certain id, how do I do this in foreach loop?
Pad (download here) is a GUI tool a bit like LINQPad, except it only works with Simple. To use it, extract it from its zip archive onto a local disk, and run Simple. method, and you can enter the parameters in the text boxes that appear when you've chosen one. v126.96.36.199 is in no way anywhere near production quality. It won’t kill you, though, or do bad things to your database, although stick to data retrieval queries for the time being. Data was created by Mark Rendle ( Six plug-ins have been additionally created Vagif Abilov has made a set of wiki pages available at Git Hub describing how to use his Simple.
The drop-down at the top left lets you choose an Open... Pad comes with the Sql Server assembly, but you can drop any of the other adapter or provider assemblies in the app folder and it should pick them up. As you type, you should get an autocomplete box showing you available methods and properties, generated from the schema of the database you’re connected to. The Trace tab should show the SQL that was run against the database for the most recent query.

If you don’t use cascading deletes, implement the delete of nested collections in the delete Method.
If I am pulling records for one day or even maybe a week, it runs at a decent pace, but once you get a month of data or more, it takes a fairly long amount of time. Is there possibly a better way that I can code this?
Sometimes this is not possible when you have foreign key constrains and rows in other tables referring your collection items.He’s a great friend and source of inspiration and also one of the best developers I know.It was Albin that first introduced me to LINQ, EF Migrations and j Query that I now use daily.After upgrading to Visual Studio 2008 RTM, you will have trouble updating Linq to SQL Classes which are read from one data context and then updated into another data context. As of now, the application runs perfectly and does exactly what I need it to, but the problem comes in when a large data set is reviewed.
