sql update - First time Updating a table -

-

I was recently allowed to update a table in our database, but this is not something I have previously And I do not try to mess up anything, I tried to search something online which is what I want to do with success.

The name of the table is dbo.Player_Miles and it has only two column data data_ID and miles which are both set (int, null)

currently in this table There are about 300 records and I have a CSV file which I have to use to update this table. There are 500k records in the file so I need to be able to:

enter new record ~ ​​250k records

Update the records that have new information ~ 200 records < / p>

leave the untouched and record which is the same information (though updating the same things will not harm the database, which I would think) ~ 50 records

Anything other than Leave the record currently in the table Which are not in the update file ~ 50 Records

I am using Ssms 2008, Server 2000.

You can contact this step ...

1) Backup Database

2) Create a temporary SQL table to keep your updated records 

  Player_Miles_Updates (PlayerId int no null, Miles int null) to create the table   
 3) Load the record in your floating table  
  bulk insert Player_Miles_updates   
 4) Start a transaction  
   
 Select PlayerImiles from Player_Miles_updates, select the mile from playerImiles_Updates, where PlayerId does not exist (PlayerIds Select)   
 6) to update your existing data  
  set Pleyrmals updates Player Player PlayerId. Miles = pmu. Miles pmiles Player_Miles_Updates from player_Miles at pmu pm.P 7) Select some rows to make sure what you want to do, select  
  Choose from Player_Miles * where in Player_Id (1,45,86 , 14,83) - Use the ID that you saw in the CSV file   
 8a) if everything went well  
  commit transaction   
 8b) If everything does not go well  
  rollback transaction   
 9) Delete a temporary table < / P>   Drop Table Player_Miles_Upda Tes

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
