One thing to keep in mind: the solution code iterates in reverse order through the parameters collection so that parameters are replaced correctly if there are more than nine parameters; if they were processed in forward order, parameter , and so on.The data adapter has a Fill Error event that occurs during a fill method.As you can see from Listing 9-5, you can compare the Statement Type member of Ole Db Row Updating Event Args to the Statement Type enumeration to find out the statement type.The Statement Type enumeration defines Select, Insert, Update, and Delete members.Next, I added a data adapter control to the form by dragging the Ole Bbd Ataadapter component from the toolbox's data tab to the form.As you drop the Ole Db Data Adapter component to the form, the data adapter configuration wizard pops up. Sql Client; private const String CATEGORIES_TABLE = "Categories"; private const String CATEGORYID_FIELD = "Category ID"; private Data Table dt; private Sql Data Adapter da; private Sql Command Builder cb; private String Builder sb; // . Event Args e) private void update Button_Click(object sender, System.
Fill Error = new Fill Error Event Handler(da_Fill Error); Data Set ds = new Data Set(); da.
Single quote delimiters are added around the string values. The solution delimits the string values for the Category Name and Description fields in the Categories table from the Northwind database used in this example.
Finally, the statement is added to a // Namespaces, variables, and constants using System; using System. Ensure that strings, dates, and any other fields are properly delimited when values are substituted for parameter names in the , the solution remains fundamentally the same if you use your own custom updating logic.
I am using the Sql Data Adapter and framework version 4.0 and found that the insert, update, and delete commands disappeared when I disposed the builder, so I saved the commands and added them back to the adapter after disposing the builder.
