To set the scrollability, concurrency, and sensitivity properties, you must specify the appropriate values when creating a Statement. The code segments shown earlier used the createStatement() method that doesn t accept any parameter values, but another version of createStatement() allows you to specify two integer values representing ResultSet properties: int resultSetType, resultSetConcurrency; // ... Statement stmt = connect.createStatement(resultSetType, resultSetConcurrency); The resultSetType parameter represents a combination of the scrollability and sensitivity properties, and it should be assigned one of the following constants defined in ResultSet: TYPE_FORWARD_ONLY, TYPE_SCROLL_INSENSITIVE, or TYPE_SCROLL_SENSITIVE. The resultSetConcurrency value represents the concurrency mode for ResultSet instances created by this statement and should be assigned the value of either CONCUR_READ_ONLY or CONCUR_UPDATABLE. You can use these constants and the createStatement() method shown previously to create a Statement that will produce ResultSet instances with the desired properties. For example, you can use code similar to the following to create a Statement and request that the ResultSet instances it creates be scrollable, sensitive to others changes, and updatable: Statement stmt = connect.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE); Note that if you specify a type of ResultSet that s not supported by the driver, it won t generate an error when createStatement() is called. Instead, the Statement will produce ResultSet instances that match the type you requested as closely as possible. In this case, for example, if the driver supports updatable ResultSet instances but not scrolling, it will create forward-only instances that are updatable. asp.net mvc qr code generator Generate a QR Code in ASP .

Now, let s take a look at some code demonstrating the partial methods In Listing 15-6, I query a Contact record from the database and change its CompanyName property Listing 15-6 Querying a Class with Implemented Partial Methods Northwind db = new Northwind(@"Data Source=\SQLEXPRESS;Initial Catalog=Northwind"); Contact contact = dbContactsWhere(c => cContactID == 11)SingleOrDefault(); ConsoleWriteLine("CompanyName = {0}", contactCompanyName); contactCompanyName = "Joe's House of Booze"; ConsoleWriteLine("CompanyName = {0}", contactCompanyName); There is nothing special about the preceding code except for the fact that I have implemented some of the partial methods that entity classes support First, I query a contact and display its company s name to the console Then, I change the contact s company name and display it again to the console Let s press Ctrl+F5 to see the output: OnCreated() called OnLoaded() called CompanyName = B's Beverages OnCompanyNameChanging() called.

Open your ASPX pageand write the code given in the following code snippet. <%@ Page ... OnCreated() called OnCompanyNameChanged() called CompanyName = Joe's House of Booze As you can see, the OnCreated method was called, followed by the OnLoaded method At this point, the record has been retrieved from the database and loaded into a Contact entity object You can then see the output of the company s name I sent to the console Next, the OnCompanyNameChanging method is called,. Some might think that this is too strict a rule If MooTools classes just abstract the native prototypal implementation, augmenting class prototypes should work This isn t the case, though: part of the abstraction provided by classes is ensuring proper object behavior The implement method doesn t just add members to the prototype directly, but instead processes the members first to make sure that everything will work as expected You might have noticed that the implement syntax is similar to the Class constructor s syntax, with both requiring an object literal describing the properties and methods to be added to the prototype of the class That s because the Class constructor itself uses implement to add the members All class members go through the implement method even the ones passed through the Class constructor. asp.net qr code generator open source QR - Code Web-Control For ASP .

You may also be able to denote the desired holdability by specifying a third parameter as in the following example and specifying either the HOLD_CURSORS_OVER_COMMIT or the CLOSE_CURSORS_AT_COMMIT constant defined in ResultSet: Statement stmt = connect.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE), ResultSet.HOLD_CURSORS_OVER_COMMIT followed by the only surprise to me, another call to the OnCreated method. Obviously, the DataContext is creating another Contact entity object as part of its change tracking procedure. Next, the OnCompanyNameChanged method is called, followed by my output of the new company name to the console. This demonstrates how you can extend entity classes using partial methods without modifying the generated code. For drivers that support JDBC 2x, it s possible to provide information that can improve the performance of a ResultSet As mentioned earlier, a row is normally retrieved from the database only after it becomes the ResultSet s current row, but JDBC 2x allows buffering or prefetching of rows by a ResultSet The fetch size specifies the number of rows that the ResultSet should retrieve from the database each time it needs to read new rows, and that value is set using the setFetchSize() method In other words, when the driver is capable of buffering database records, this value identifies the maximum number of records that should be buffered For example, suppose you execute the following code: ResultSet rset = stmtexecuteQuery("SELECT * FROM MYTABLE"); rset. The implement method looks through each of the items from the object argument and checks whether it should process that particular item before it adds it to the prototype The processing depends on the type of the item: properties undergo different processing from methods, and there is special processing done to items with particular keys Since we re talking about members now, we won t go into detail about those keys here; instead we ll focus on how implement processes methods and properties.. asp.net create qr code ASP .
