best way to find the maximum value that is less than a specific value?
Hello guys,.What is the fastest way to find a record that has value max of a field and there is a limitation to a specific value for ex:
example 1:
create table dummy(master_id number, detail_id number, some_value varchar2(80));
insert into dummy values (1,1,'bla bla1');
insert into dummy values (1,2,'bla bla2');
insert into dummy values (1,3,'bla bla3');
insert into dummy values (2,1,'bla bla4');
insert into dummy values (2,2,'bla bla5');
insert into dummy values (2,3,'bla bla6');
insert into dummy values (2,4,'bla bla7');
commit;1 3 bla bla3
2 4 bla bla7Select *
from dummy d1
where detail_id = (select max(detail_id) from dummy d2 where d2.master_id = d1.master_id);
OR next one which i prefered.
Select *
From (Select d1.* , row_number() over(partition by master_id order by detail_id desc) r
from dummy d1)
Where r = 1;Edited by: elcaro on 13.Ara.2011 04:02

Please try this with your new test tables:
select m.master_id,
m.master_data,
max(d.id) keep (dense_rank last order by data_value, d.id) d_id,
max(d.master_id) keep (dense_rank last order by data_value, d.id) d_master_id,
max(data_value) keep (dense_rank last order by data_value, d.id) d_data_value,
max(date_data) keep (dense_rank last order by data_value, d.id) d_date_data
from master_dummy m, detail_dummy d
where m.master_id=d.master_id
and d.date_data <= to_timestamp('04012010','ddmmyyyy')
group by m.master_id, m.master_data

(I added d.id column in the order by the dense_rank. clause that could make a difference when there is more than one line with the same data_value).

Is it possible to connect a simple 1 d array to a digital indicator or what would be the best way to display the numeric values of the array on the front panel? Examples or suggestions would be greatly appreciated.
Thank you

Thank you Adam, it's originally in a while loop, I placed it in a loop for example, wired County in the for loop and presto, this son of a digital indicator. It works very well. Thanks for the help folks.

[10g] way to find the least value greater than a value?
I have a simple (I think) question...
Part 1:
Is there a way to determine the least value among a set of values, which is greater than 0?
A few examples:
Part 2:Set of values: {0,1,2,3} Return value: 1 Set of values: {0,5,10,20,100} Return value: 5 Set of values: {1,4,9,11} Return value: 1
Same thing, but greater than some given value, 0 is not necessary.
In particular, I'm looking for an effective way to achieve this. I think I can do it with a set of CASE statements, but it becomes really complex values compare more than you.Set of values: {0,1,2,3} Parameter value: 2 Return value: 3 Set of values: {0,5,10,20,100} Parameter value: 2 Return value: 5 Set of values: {1,4,9,11} Parameter value: 2 Return value: 4
My first thought was to use the function LESS, but which does not allow me a way to use a parameter.
Any suggestions?Hello
Thanks for posting the sample data.
I know that it takes hard work to do, but it's really help people who want to help you. Sometimes, it can help you, too, giving you new perspectives on what the problem really is. As often do not, when I am confused by something and need help, I discovered an answer while assembling a test script and write a description of the problem.You can use the function LESS, with CASE expressions as arguments, to do what you want:
SELECT ord_nbr , seq_nbr , time_spent / CASE WHEN comp_qty > plan_qty THEN LEAST ( CASE WHEN ord_qty - scrap_qty > 0 THEN ord_qty - scrap_qty ELSE 1E99 END , CASE WHEN plan_qty > 0 THEN plan_qty ELSE 1E99 END , CASE WHEN comp_qty > 0 THEN comp_qty ELSE 1E99 END ) END AS unit_time FROM ord_detail ;This means that your actual data are never as large as 1E99, and at least one of the three expressions will be greater than 0.
If or any of these assumptions are false, I'm sure we can find a solution, but it will probably be even messier.It should work in Oracle 8.1.

I have 7 sets of possible values for the wctr_id column, which are groups of similar/identical positions and should be treated as the same, assuming that the ord_nbr, sub_ord_nbr and major_seq_nbr are the same. In my case statement example above, every time I find 'H211' or 'H212', I'm replacing it with "Z211', which is my new unique identifier for all wctr in the Group ("H211', "H212"). I have 7 of these kinds of groups that should be replaced by a new unique identifier. Is my statement CASE (above) the best way to do it, or is there a better way? These groups of similar-wctr_id are not listed in a table anywhere.Hello
As always, thanks for posting the CREATE TABLE and INSERT statements. It is very useful and leads to the more quickly, better solutions.
Another thing that is useful and promotes better solutions, faster, is to simplify your problem.
For example, you need to calculate a large number of aggregates, but looks like you already know how to do this. This issue only affects the CASE expressions, and how they interact with the GROUP BY clause. So just cut most of the aggregate functions.
Also, it seems that the finer points of view one online have nothing to do with your current problem. For purposes of recognition of this problem, pretend that one is a regular display, so it does not clutter the main request.I think your problem might be reformulated as follows:
You already have a query like this:CREATE OR REPLACE VIEW a AS SELECT s1.ord_nbr , s1.sub_ord_nbr , MIN ( CASE WHEN s1.act_start_dt > TO_DATE('01/01/2000','mm/dd/yyyy') THEN s1.act_start_dt END ) AS ord_min_start FROM op_detail s1 GROUP BY s1.ord_nbr , s1.sub_ord_nbr ; SELECT o.part_nbr , s.major_seq_nbr AS op_nbr , CASE -- CASE statement to replace similar-to wctr_id's with a single new wctr_id, so we can treat them as the same WHEN s.wctr_id IN ('H211','H212') THEN 'Z211' ELSE s.wctr_id END AS wctr , MIN(s.plan_su_rsrc) AS min_plan_setup -- lots of other agtgregates go here in real query , CASE WHEN a.ord_min_start > ADD_MONTHS(SYSDATE,-12) THEN '12 mos. back' WHEN a.ord_min_start > ADD_MONTHS(SYSDATE,-24) THEN '24 mos. back' WHEN a.ord_min_start > ADD_MONTHS(SYSDATE,-36) THEN '36 mos. back' ELSE '37 mos. back +' END AS time_period FROM ord_master o , op_detail s , a -- in real query, a is an in-line view WHERE o.ord_nbr = s.ord_nbr AND o.sub_ord_nbr = s.sub_ord_nbr AND o.ord_nbr = a.ord_nbr AND o.sub_ord_nbr = a.sub_ord_nbr AND o.ord_type = 'AA' AND o.ord_stat IN ('CL','OP') AND s.oper_stat IN ('CL','CP') GROUP BY o.part_nbr , s.major_seq_nbr , CASE -- CASE statement to replace similar-to wctr_id's with a single new wctr_id, so we can treat them as the same WHEN s.wctr_id IN ('H211','H212') THEN 'Z211' ELSE s.wctr_id END , CASE WHEN a.ord_min_start > ADD_MONTHS(SYSDATE,-12) THEN '12 mos. back' WHEN a.ord_min_start > ADD_MONTHS(SYSDATE,-24) THEN '24 mos. back' WHEN a.ord_min_start > ADD_MONTHS(SYSDATE,-36) THEN '36 mos. back' ELSE '37 mos. back +' END ORDER BY o.part_nbr , CASE WHEN a.ord_min_start > ADD_MONTHS(SYSDATE,-12) THEN '12 mos. back' WHEN a.ord_min_start > ADD_MONTHS(SYSDATE,-24) THEN '24 mos. back' WHEN a.ord_min_start > ADD_MONTHS(SYSDATE,-36) THEN '36 mos. back' ELSE '37 mos. back +' END , s.major_seq_nbr ;which produces this output:
` MIN_ PLAN_ PART_NBR OP_N WCTR SETUP TIME_PERIOD ---------- ---- ----- ------ -------------- ABC-123 0081 X516 .0 12 mos. back ABC-123 0130 Z211 .5 12 mos. back ABC-123 0170 X928 .0 12 mos. back ABC-123 0324 Y000 .1 12 mos. back ABC-123 0120 H214 .3 24 mos. back ABC-123 0122 T203 2.5 24 mos. back ABC-123 0130 Z211 .5 24 mos. back ABC-123 0170 X928 .0 24 mos. back ABC-123 0324 Y000 .1 24 mos. back ABC-123 0324 Y000 .1 37 mos. back +The output is correct; the problem is, can we get the same results without 2 copies of the expression BOX wctr and 3 copies of the expression BOX time_period?
What is a good description of the problem?To start, you can use aliases for columns in the ORDER BY clause. Unfortunately, it's the only place where you can use column aliases in the same query, where they are defined . You can calculate them in a query-sib and then use them in queries Super.
In other words, wouldn't be nice if we had a table just like op_detail, but with an extra column called wctr? Make a view: either a regular view (especially if wctr, calculated in the same way, to be used for several different queries) or view online, as shown below.
Wouldn't be great if there was a table that was like a, except that he had calculated alreay time_period? Make a view: either a regular view, or a view online, as shown below.SELECT o.part_nbr , s.major_seq_nbr AS op_nbr , s.wctr , MIN(s.plan_su_rsrc) AS min_plan_setup -- lots of other agtgregates go here in real query , a2.time_period FROM ord_master o , ( -- Begin in-line view s, with data from op_detail SELECT op_detail.* -- or list all columns needed in main query , CASE -- replace similar-to wctr_id's with a single new wctr_id, so we can treat them as the same WHEN wctr_id IN ('H211','H212') THEN 'Z211' ELSE wctr_id END AS wctr FROM op_detail ) s -- End in-line view s, with data from op_detail , ( -- Begin in-line view a2, to compute time_period SELECT a.* , CASE WHEN ord_min_start > ADD_MONTHS(SYSDATE,-12) THEN '12 mos. back' WHEN ord_min_start > ADD_MONTHS(SYSDATE,-24) THEN '24 mos. back' WHEN ord_min_start > ADD_MONTHS(SYSDATE,-36) THEN '36 mos. back' ELSE '37 mos. back +' END AS time_period FROM a -- in real query, a is an in-line view ) a2 -- End in-line view a2, to compute time_period WHERE o.ord_nbr = s.ord_nbr AND o.sub_ord_nbr = s.sub_ord_nbr AND o.ord_nbr = a2.ord_nbr AND o.sub_ord_nbr = a2.sub_ord_nbr AND o.ord_type = 'AA' AND o.ord_stat IN ('CL','OP') AND s.oper_stat IN ('CL','CP') GROUP BY o.part_nbr , s.major_seq_nbr , s.wctr , a2.time_period ORDER BY o.part_nbr , a2.time_period , s.major_seq_nbr ;In your example, wctr is identical to wctr_id, except for two values. If it was more complicated (for example, if there is not only 2 values that must be mapped on 'Z211', but also 3 to did not amount to "Z987", and 1 which should be treated as "A012" and 5 who should appear as "A666" and...), then you pourriez encode this in an expression BOX humongeous (one nested expression BOX if it involves more than 128 branches) , but it actually belongs to a table, where you have the gross wctr_id (such as "H211") in a column and its equivalent correspondent (for example "Z211") in another. I know that you said that you cannot create new tables; I'm just pointing out that then you can tell people that won't let you create tables, it's a bad idea, likely to lead to errors and some time in the future.

Best way to set the default values for the form elements
Hello
I have a form with a lot of defaults that is mentioned below...
I am currently using calculation-> after presents... then when we create/update a record... these computaion takes place and the default value for the inserted values get... THIS WORKS PERFECTLY WELL.Field value created by :APPL_USER creation_date SYSDATE last_updated_by :APPL_USER last_update_date SYSDATE item1 value1 item2 value2
I want to know... If this approach is fine OR we can have a better approach to achieve...?
Thank you
DeepakHello
I think it's good if it fits your need.
But why you have these fields in the form?
created by: APPL_USER
CREATION_DATE SYSDATE
last_updated_by: APPL_USER
last_update_date SYSDATEThe user can enter the ones?
I thought that those who are to audit and I would fill those drop with trigger in the database.
So that you get the same "correct" values if you need to manipulate the data with example of sql clientBR, Jari

The best way to find the name of the installed application module?
If you don't know the name of an application module, how can you find it?
For example, if I have the name of jad file from another application, can I assume that the name of the application module is basename of the jad? As in, a name of jad MyApp.jad would result in a module name to 'MyApp '?
That was my assumption in a first time, and it of that he seems to be the case, most of the time, but not all. In particular, if the jad's name:
MyApp - 1.0.0.jad
I found that the name of the actual module on a "BOLD" v4.6.167 running (and the 4.6.0 JDE the bold Simulator) is
MyApp$ 2 d 1
However, * on an another "BOLD" * (this a v4.6.0.162 running), the exact same application indicates a module name of
$ 2 d $1 2e0 MyApp$ 2e0
That's why I wonder if there is way to get more definitive an application module. I scoured the API documentation and the solution isn't jumping home.
Thoughts?
Thanks for any help.
Ah. I can also see if I need to 'escape' my module names. If this isn't the case, then I can watch an exact match in the list of module names. If I have, it seems that I still need to look for something, "close enough" and hope for the best.

What is the best way to get the minimum or maximum of a table of numbers value?
Let's say I have a table of numbers: [2,3,3,4,2,2,5,6,7,2]
What is the best way to find the minimum or maximum value in the table?
Now, just get the maximum, I'm a loop in the table and reset a variable to the value if it is greater than the existing value:
What I ended up doing was sorting table (descending to MAX) upward for MIN and then grabbing the first element of the array. Works like a charm in very few lines of code.
Thank you.

Apple Extreme, Time Capsule and Express on the same system, what is the best way to set it up so that all devices smoothly from one end of the House to another?
I'm going to assume that you plan to have wireless devices.
Let's say that the Capsule is your "main" router If this is the case, then it must be located in the House, so that the distance between the time Capsule is the same for the outside walls of the House.
Then, on the 'left' side of the House, looking for an airport to midway between the Capsule and time of the outer wall of the House. Do the same thing the 'right' side of the House.
In other words, each of the two airports that "extend" the wireless signal are located at equal distance from the Capsule of time... but they are in opposite ends of the House.
If you intend to interconnect all the airports and Time Capsule using a permanent, Ethernet wired... which by far is the 'best' way to put in place a network in terms of performance and reliability... then you can locate one of the devices anywhere you want.
