Dataadapter update not updating database
For example, if you call Delete on a row on the Data Set, then when Update is called on the Data Adapter, the Delete Command of the Data Adapter will be called using the particular row in the Data Set.Note: Keep in mind that this Update is different than a SQL UPDATE statement.The Find method returns the row with Customer Id = Tst ID.After that I assign values of the row and call the Data Adapter's Update method. Updating data using the Data Adapter's Update method sender, System. Listing 5-50 deletes the row with the value Tst ID.Fill(ds Production,"Companies"); String str Development SQL = "SELECT * FROM [Global].[dbo].[Companies] WHERE Company ID ='" str SQLDest Database "'"; Sql Data Adapter da Development = new Sql Data Adapter(str Development SQL, cn Development SQL); Data Set ds Development = new Data Set(); da Development. If you call the Get Changes method on the second Data Set, I bet you'll find you get an empty Data Table in it.Fill(ds Development,"Companies"); if (ds Production.

2) With respect to a dataset how can I get at the value of a specific Row/Column? Ron Sql Connection cn Production SQL = new Sql Connection("Data Source=SQLSVR01; Integrated Security=SSPI; Initial Catalog=Master"); cn Production SQL.
As you can see from listing 5-48, I created a filled Data Set and created a new Data Row using the Data Table. After creating a Data Row, I set its column values and called the Data Adapter's Update method and displayed data in the Data Grid.
I added new rows to the Customers table with Customer Id, Customer Name, and Company Name (named Tst ID, Lana Jackob, and Mindcracker Inc., respectively). Adding data using a Data Adapter's Update method Listing 5-49 shows an example that edits row data.
Open(); Sql Connection cn Development SQL = new Sql Connection("Data Source=SQLSVR02; Integrated Security=SSPI; Initial Catalog=Master"); cn Development SQL. i'm rather new in this area so i'm trying to understand what you are saying.
Open(); String str Production SQL = "SELECT * FROM [Global].[dbo].[Companies] WHERE Company ID ='" str SQLDest Database "'"; Sql Data Adapter da Production = new Sql Data Adapter(str Production SQL, cn Production SQL); Data Set ds Production = new Data Set(); da Production. There was definitely a change, I entered Null values in two of the fields in the database where the second server had values.
