013885925, creates 75 buckets, and reports 58 buckets 10g gives a density of 0013885925, creates 75 buckets, and reports 75 buckets The bucket count is largely a cosmetic thing, but the variation in density and actual bucket count occurs because 8i uses the analyze command internally to generate the histogram, whereas 9i and 10g run the SQL statement shown at the end of the Getting Started section of this chapter The reports you see in the 10053 trace about histograms (particularly height balanced histograms) vary across versions as well and the output from 10104 is slightly different from the output from 10102 The following three examples all came from running exactly the same script as you can see, the clarity of information keeps improving: Version 1010.

Copy constructors take a tracking reference (%) as a parameter, as shown in Listing 4-15. Listing 4-15. Using Tracking References with Copy Constructors // passing_with_copy_ctor.cpp using namespace System; ref class R { int val; String^ str; public: property int Value { int get() { return val; } void set(int i) { val = i; } } property String^ Label { String^ get() { return str; } void set(String^ s) { str = s; } } R(int val_in, String^ label) : val(val), str(label) { } R(const R% r) { // Copy the elements of R. // Value is a value type, so it gets copied. val = r.val; // Strings are immutable, so // a reference copy will work here even // in a copy ctor. str = r.str; } }; Unlike in classic C++, there is no default copy constructor generated for a managed class, so you need to define one explicitly in order to use this method of parameter passing. The parameter to a copy constructor is normally declared const, although the language does not enforce this. If you do use a const reference as a parameter, you cannot use properties in the copy constructor, since properties take nonconstant parameters. The solution is to use the fields directly in the body of the copy constructor, as in Listing 4-15.

You can even use the letter keys on your keyboard to instantly jump down to the first item matching either letter on the key (if there are two letters), or jump down to a matching menu item, or jump down to a matching item in a list (like the long list in the Options icon).

More important than the cosmetic details, though, is the fundamental problem of bad luck that this example highlights. Look back at the list of (endpoint_number, endpoint_value). You will notice that some rows are clearly missing there is no row with the endpoint_number set to 74, for example. This is why we get a report (10g version) of 75 uncompressed buckets, but only 59 endpoint values. Some of the buckets are implied and not stored in the database. We ought to see a row with the values (74, 80) but Oracle can infer that row. Expanding the previous output to show all the buckets, stored and inferred, we should see the following: ENDPOINT_NUMBER ENDPOINT_VALUE --------------- -------------... 59 71 60 72 61 73 62 73 63 74 64 74 65 75 66 76 67 76 68 77 69 77 70 78 71 78 72 79 73 79 74 80 75 80

You can even use the number keys on your keyboard to instantly type a new date or time, or select an entry in a drop-down list with that number. Examples include the following: Typing 40 in the Minutes field to set the minutes to 40 Typing 9 in the Hour field to get to 9 AM or PM This also works in the fields where drop-down list items start with numbers, like in the Reminder field in the calendar or tasks. Typing a number 9 would immediately jump you to the 9 Hours setting.
