There are two anomalies to note in particular The obvious one is that the final cost for the max() query is much less than the final cost for all the other queries, which all have the same cost (In fact, when you enable CPU costing, you find that the other four queries also have exactly the same CPU cost, despite the obviously different requirements for processing) In theory, you might expect Oracle to sort the data as the first step of any of these operations However, the max() example can be optimized without sorting despite the appearance of the sort line in the execution plan The run-time code simply has to scan the incoming data and keep track of the largest value so far The optimizer calculations reflect this operation exactly If we look at the other operations, it is clear that the order by will need a sort. vb.net code 39 reader VB .

Similarly, the distinct could be implemented by sorting the data, scanning the sorted result set, and reporting a row only when it differed from the previous row The optimizer doesn t bother trying to put a figure on the tiny CPU difference involved in the last step of this operation The same approach applies to the group by, except we maintain running totals (in this case a count) and pass forward the totals along with the row data whenever the row differs from the previous row The second anomaly shows up when you examine the query that does the group by followed by the order by look carefully at the code, and you will see that my group by clause is on col1, col2, but my order by clause is on col2, col1 the opposite way around. txtPwd.Text = txtPwd.Text.Replace("'","''") txtFName.Text = txtFName.Text.Replace("'","''") txtLName.Text = txtLName.Text.Replace("'","''") txtPhone.Text = txtPhone.Text.Replace("'","''") txtMobile.Text = txtMobile.Text.Replace("'","''") txtEmail.Text = txtEmail.Text.Replace("'","''") txtAddress.Text = txtAddress.Text.Replace("'","''") txtBirth.Text = txtBirth.Text.Replace("'","''") ' Optional values without quotes as they can be the Null value ...etc... 19.

It would be very easy to assume that Oracle would have to sort the data once to do the group by, then sort it again to do the order by However, the optimizer is smart enough to determine that both the group by and the order by could be satisfied by a single sort operation.. How It Works By having the chance to run the suspect code one step at the time while checking the status of key variables, you were able to determine exactly what was going on. The QuickWatch window proved very useful in allowing you to examine the value of any variable. Meanwhile, the Watch window allowed you to make a change to one of your variables and see how the application continued to run with the changed value. You also used the ability to move the execution point back in order to test fixes, which was essential to determine if your understanding of the problem was accurate, as well as if the solution worked. Once you had identified the bug, it was easy to write a few lines of code to fix it. vb.net code 39 reader Visual Studio . NET Barcode Scanner Library API for . NET Barcode ...
