How to query an array type without using Loops(FOR,etc)
Hi allI'm just a beginner working with oracle DB. I have a basic question about the TYPES of TABLES in oracle.
creating table example (a number, b varchar2 (10))
/
Set serveroutput on;
declare
TYPE tab_type IS TABLE of example % ROWTYPE;
t_tab tab_type: = tab_type();
Start
I'm IN 0.2
loop
t_tab.extend;
t_tab (t_tab.last) .to: = i;
t_tab (t_tab.last) .b: = "maru";
dbms_output.put_line (t_tab (t_tab. (Last) .at);
end loop;
-What I CAN DO SELECT * FROM THE TABLE t_tab without using a cursor to iterate line by line
-Since I need to compare the values in a table called HAND with this SAMPLE table.i need to check if all the files present in the table MAIN is present in the
-Type of table table SAMPLE. I do not want to insert into a temporary table (because it becomes an overhead projector) and compare the results.
end;
Kindly help me in this regard and let me know if you need more details.
Thanks in advance.
Maybe you would like
create type mytype as object
(
a number,
b varchar2(10)
);
/
create type tab_type as table of mytype;
/
declare
t_tab tab_type := tab_type();
sRES varchar2(10);
begin
for i IN 1..2
loop
t_tab.extend;
t_tab(i) := mytype(i,'maru');
end loop;
select b
into sRES
from table(cast(t_tab as tab_type))
where a = 2;
dbms_output.put_line(sRES);
end;
/

Given that I can't grasp how to open a browser window without using a mouse, it dawned on me that I can open new windows in just a window browser. In fact, I would like that my home page contains all my most visited sites. However, I am such a novice at this, I don't understand half the jargon, as what is the difference between a window and a tab. I am a CPA, and for the first time in my life, I have no support from the computer. I have called my programmer to answer questions and fix my computer. Now I'm on my own and not completely lost since I tried to learn from my programmers, but we can't assume that I know nothing (or almost). Thus, when answering my questions, please pretend I'm in third year.

Edited by: sake1 1-dec-2010 08:16I used Altavista and found an example, how is it?
DECLARE /* there is no built array in oracle, you must declare your own */ TYPE Numarray IS TABLE OF NUMBER INDEX BY BINARY_INTEGER; /* the array of numbers - using assoc array because I can start with zero like traditional arrays */ Nums Numarray; n NUMBER := 0; Temp NUMBER; BEGIN /* load up the array, put 20 random values in the array, in array indicies 0 to 19 */ FOR i IN 0 .. 19 LOOP Nums(i) := Round(Dbms_Random.Value(1, 1000)); END LOOP; /* get the array size */ n := Nums.Count(); /* display the unsorted values - loop through the whole array and print out the values */ Dbms_Output.Put_Line('unsorted:'); FOR i IN Nums.First .. Nums.Last LOOP Dbms_Output.Put_Line(Nums(i)); END LOOP; /* bubble sort - using two loops, compare each value with the one after it if the one after the current one is smaller , then switch their locations in the array, this is just like standard bubble sorts in other languages. The only real diff is the syntax. */ FOR i IN 0 .. n - 1 LOOP FOR j IN 0 .. n - (i + 1) - 1 LOOP IF (Nums(j) > Nums(j + 1)) THEN Temp := Nums(j); Nums(j) := Nums(j + 1); Nums(j + 1) := Temp; END IF; END LOOP; END LOOP; /* display the values sorted */ Dbms_Output.Put_Line('sorted'); FOR i IN Nums.First .. Nums.Last LOOP Dbms_Output.Put_Line(Chr(9) || Nums(i)); END LOOP; END; /* unsorted: 155 909 795 977 942 214 105 269 283 820 108 594 784 921 856 736 802 457 951 411 sorted 105 108 155 214 269 283 411 457 594 736 784 795 802 820 856 909 921 942 951 977 */
In the code the first comment is wrong in fact, I think, this one:
"There is no table built in oracle, you must declare your own."
I remember there are some types of collection of the system, if I not mix with something, I remember there was a sort of like they were undocumented, so we can say legally that the comment in the code has always been right. -
How can I get through forms without using my mouse?
On a form web (as a survey), I used to be able to tab on the 'submit' button, press ENTER, and submit the page. Who stopped working some time over 2 months, probably with an update of Firefox.
I need to have people to do a series of short surveys, a typed RESPONSE per page. (They must be structured in this way for a moment that we do). Previously, people could type in their response, to 'other' tab and press return, which would load the next page. This seems to have stopped working, and I can't find a way to access the next page without using the mouse. Back and forth between typing and clicking on are super annoying and slow people down, by our much less precise time measurements. How can I return this feature?
Seems to work for me. I did this quick form with Google Drive: https://docs.google.com/forms/d/1b493Op_imKXg8Q_GNMmRquuvCutZzyQ0RuQbgKRPD6A/viewform?usp=send_form
Can you give an example of this form does not work? -

You cannot retrieve files deleted with the help of software. And even using

Change the value of the array element without using the keyboard
I have a control array on my front, say 1 d, 10 items.
In addition, the front panel should be used with a touch screen, so I have a Subvi keyboard that should be called when I choose one of the elements of the array. Therefore, no keyboard entry is allowed.
My question is, how can I determine which element that the user hit/clicked?... .and how to change this value?
-Mike
Gents nevermind, found a way to emphasise that if this is the best way, but I got it.
In my structure of the event, I have an event looking for the mouse event down in regards to the control array. This event triggers my screen touch keyboard Subvi to fire, and the closure of the Subvi I pass its value to the ArrElem.Value property to assign the table a hit/clicked item. Works.
