One unit of the difference appears because the hidden parameter _tablescan_cost_plus_one is set to true in the newer versions of Oracle, but false in the older version. The other unit is because the tables are slightly different sizes thanks to a change in the behavior of initrans. In 9.2, the initrans storage parameter on a table defaults to 2 (even if you set it to 1, and even when the data dictionary claims that it is 1). Moreover, when you do a create table as select, the actual number of slots in the interested transaction list (ITL) of each of the initially created table blocks is three rather than the two dictated by initrans. In the example, this tiny difference is just enough to make the emp table just one block bigger, which just happens to increase the cost of scanning it by one. qr code reader library .net C# Imaging - Read 2D QR Code in C# .

Introduction. In this tip, I'll cover a simple method to do with a QR code inside a standard control. For reference, I will use ZXing . Net library from ... You will notice that the execution plans are the same in all three cases but the costs and cardinalities show some dramatic differences Since the cost and cardinality of one line of an execution plan can dictate the optimizer s choice of join orders and join methods for the whole plan, you will appreciate that the changes in calculations used for this operation could have a significant difference for more complex queries as you upgrade your version of Oracle Look at the cost for the 8i execution plan it looks as if the optimizer has simply forgotten to factor in the cost of the subquery at all, so the cost of the query is just the cost of the driving full tablescan The cost that 9i works out does, at least, appear to have some sort of rationale behind it.

The VB . NET QR Code scanning decoder control component fast reads QR Code barcode images in .NET framework projects. Like IndexOf, but searches from the end of the array or specified index. Changes the size of the array. Reverses the order of a 1D array (or portion of the array). Sets an element to the specified value. One component of the 35,035 is the cost of the driving tablescan (35) in line 2 According to the execution plan, the number of rows (card =) on the driving tablescan will be 1,000 so the subquery (which is also a tablescan) will apparently have to be executed 1,000 times: 1,000 * 35 = 35,000 Adding these two components, you get the required total of 35,035 But what is the source of the 1,000 that the optimizer has estimated as the cardinality of the driving tablescan Unfortunately, in another stage of the calculations, the optimizer has worked out that the cardinality of the final result set will be 1,000 This comes from the fact that the only predicate on the driving table is salary > not yet known result of subquery, and this predicate has been given the same 5% selectivity as column > :bind_variable. If you would prefer not to send the call immediately to voice mail and simply let it ring a few times on the caller s end, but you don t want to hear the ring (perhaps you are in a movie theater or a meeting), when the call comes in, press the Mute key on the top of your BlackBerry. The Mute key has the small Speaker icon with the line through it. All this will do is silence the ring. You may still pick up the call or let the caller go to voice mail. qr code reader c# .net VB .
