Help with fully functional test program
I'm using a trial of InDesign. I have looked at several tutorials and try to imitate them and prompts (or at least some of them) will not work. I'm going to make changes as the tutorial done... and I can not open many functions, cannot display two pages side by side in spite of the by clicking on the prompt at the end of brewing. The 'clicks' do not work on some functions. I can add a rectangle with the tool of rec, which works, but when I try to add the color of the coloured bar scrolling does not work and if I click on one that I can do, nothing happening... no answer. Trying to get one of the pages down so that they are side by side (2 pages) and no page is picked up to move? I closed and reopened, restarted... the thing is that the first time I tried, it did let me do these features. But since I closed it the first time, he just left work fully? I chose the tool select... I've tried everything. I notice that my scroll bar strives to make a difference (on my mouse) but not the scroll edge, and in many cases, I'm not able to use my mouse to click on an element?
Any ideas? Adobe offers any help on a trial?
Thank you!
Beth
It is important we say what ID and your OS version, but I'll take a shot in the water and guess that perhaps you run Windows 7 or Vista. If this is the case, see InDesign tools and panels meet not the clicks of the mouse (Windows 7/Vista)

Need help with the function or metric derivative to calculate percentages of threshold for a measure
Hi, first post to the community that I am a n00b Foglight needing help.
A thing (in fact the only thing) I like Microsoft SCOM is how this graph of the availability of a metric, and I want to do the same thing in Foglight. I understand that this could be a derived measure or a function, I need, but am a bit lost right now.
Let's say I have a metric and created thresholds as follows: normal included 0, 50 inclusive, warning critical 75 inclusive, fatal 100 inclusive + 9999 included. The metric is measured every so often and more often (99%) of the time it's normal. I want to visually represent that fact, together with the percentage of time that he spends in the strips of quick, critical and fatal alert threshold.
For the dashboard but mainly reports I am looking for the percentage of time that the metric through each of the bands of threshold and put them in some form of chart, preferably very similar to how SCOM it: -.
I would also like to increase this visually with a quantification for the oriented numercally, in order to insert values in the report for clarification would be great too, for example:-Normal:-99% 0.5% warning critical Fatal 0.1% 0.4%
I think of what I have already learned that we have to include a 'blue' band for threshold indefinite in order to operate on a regular basis for any measure.
I do not seem to come up with this concept in Foglight but I think it could be very useful to have something. Any help is most appreciated.
Health and alarms is a standard display which can be used on any object topology. You can access it from the data browser and should also be able to specify this dashboard as a preference in personalized dashboards.

Help with analytical functions - Windowing
Hello
I'm using Oracle 11.2.0.4.0.
I want to do the sum of all amounts for each window of 3 days from the date of the oldest rolling. I also want to name each window with the date limit for the period of 3 days.
My requirement is slightly more complicated, but I use this example to illustrate what I'm trying to
create table test (dt date, amt, run_id number);
Insert test values (to_date (' 22/04/2015 ',' dd/mm/yyyy'), 1, 1);
Insert test values (to_date (' 23/04/2015 ',' dd/mm/yyyy'), 1, 1);
Insert test values (to_date (' 24/04/2015 ',' dd/mm/yyyy'), 1, 1);
Insert test values (to_date (' 25/04/2015 ',' dd/mm/yyyy'), 1, 1);
Insert test values (to_date (' 27/04/2015 ',' dd/mm/yyyy'), 5, 1);
Insert test values (to_date (' 28/04/2015 ',' dd/mm/yyyy'), 2, 1);
Insert test values (to_date (' 29/04/2015 ',' dd/mm/yyyy'), 1, 1);
Insert test values (to_date (' 04/30/2015 ',' dd/mm/yyyy'), 1, 1);
Insert test values (to_date (' 01/05/2015 ',' dd/mm/yyyy'), 1, 1);
Insert test values (to_date (' 02/05/2015 ',' dd/mm/yyyy'), 1, 1);
Insert test values (to_date (' 03/05/2015 ',' dd/mm/yyyy'), 1, 1);
Insert test values (to_date (' 04/05/2015 ',' dd/mm/yyyy'), 1, 1);
The output should look like the example below. The period column requires
to show the end of each 3-day study:
AMT DT SUM_PER_PERIOD PERIOD
22/04/2015 1 1 24/04/2015
23/04/2015 1 2 24/04/2015

05/02/2015 10 50 3/05/2015
05/03/2015 1 21/3/05/2015
All I can manage this is
Select dt
TN
, sum (amt) on sum_per_period (PARTITION BY run_id ORDER BY dt vary from 2 PAST current line)
of the test
order by dt;
Can anyone help?
It's very kind of you to give the insert and create instructions... but I corrected the data a bit
It does not match the output see you below
starting from 29/04, you forgot to change the dates and numbers of...
insert into test values (to_date('22/04/2015','dd/mm/yyyy'),1,1); insert into test values (to_date('23/04/2015','dd/mm/yyyy'),1,1); insert into test values (to_date('24/04/2015','dd/mm/yyyy'),1,1); insert into test values (to_date('25/04/2015','dd/mm/yyyy'),1,1); insert into test values (to_date('27/04/2015','dd/mm/yyyy'),5,1); insert into test values (to_date('28/04/2015','dd/mm/yyyy'),2,1); insert into test values (to_date('29/04/2015','dd/mm/yyyy'),20,1); insert into test values (to_date('30/04/2015','dd/mm/yyyy'),30,1); insert into test values (to_date('01/05/2015','dd/mm/yyyy'),5,1); insert into test values (to_date('02/05/2015','dd/mm/yyyy'),5,1); insert into test values (to_date('02/05/2015','dd/mm/yyyy'),10,1); insert into test values (to_date('03/05/2015','dd/mm/yyyy'),1,1);your periods will change if you insert a new first date...
so I guess you want a specific date... in this case 22/04/2015 and a specific end date
creation of periods from this first date and then grouping of these periods is easier with a first fixed date and a delta of 3 days.
the first step is to match the periods to your data (adapted)
with periods as ( select date_start + (level-1) * period_days period_start, date_start + level * period_days period_end, period_days from ( select to_date('21/04/2015', 'dd/mm/yyyy') date_start, to_date('04/05/2015', 'dd/mm/yyyy') date_end, 3 period_days from dual) connect by date_start + level * period_days < date_end) select * from test t, periods p where t.dt > p.period_start and t.dt <= p.period_endThis gives your data with the dates of beginning and ending period

Can anyone help with my function please?
Hi all
I created a function and I was wondering if someone could take a look and help me with a particular problem, that I am experiencing. The function is shown below. It works fine, but I get the following error:
The method call failed because [System.Object []] does not contain a method named "op_Division.
D:\SR\WindowsPowershell\Modules\SRvSphereTools\SRvSphereTools.psm1:875 char: 13
+ $VMprops = [ordered]@{'Name' = $vmview.] Name;
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo: InvalidOperation: (op_Division:String)], RuntimeException
+ FullyQualifiedErrorId: MethodNotFound
Now, I know when I get this error whenever I enter a virtual machine name that has a suffix. Which means that I will enter a virtual machine as a 'Server' name and it relates very well again. When I enter a name such as "server_' it relates with the above error again.» I also noticed if I go in $ server he reports again with the name shortened to the server. Is it something to do with my input variables, do not deal with the prefix. I wouldve thought that he would bring back ' the two inputs to the output.
As usual any help would be MUCH appreciated.
Thank you

First off the coast to let put me the warning that I am not the right Wick informed in PL/SQL. I use this for an example posted in the forum of the APEX.
I need the function to return values based on the user role. I know, it's probably the ugliest pl/sql, you may have seen yet ;) I hope that you guys can decipher the logic that I use. Obviously, this code does not validate.
You guys could help me with this?

More help with analytical functions
I had great hellp here yesterday and I need once more today. I guess I'm still not able to get a solid understanding of analytical functions. So here's the problem:
table with 3 collars:
product_id (int), sale_date (to date), count_sold (int) - each file show that the number of items have been sold for the product at a given date.
The query should return the 3 passes of the table AND a fourth column that contains the date with the best sales of the product. If there are two or more dates with equal sales, the last being is chosen.
Is this possible using an analytical function appropriately and without using a subquery?
example:
product_id, sale_date, count_sold, high_sales_date
1, 01-01-2008, 10, 05/10/2008,.
1, 2008-03-10, 20, 10/05/2008
1, 10/04/2008, 25, 05/10/2008
1, 10/05/2008, 25, 05/10/2008
1, 01/06/2008, 22, 05/10/2008
2, 05/12/2008, 12, 05/12/2008
2, 06/01/2009, 10, 05/12/2008
Thank youHello
Try this:
SELECT product_id , sale_date , count_sold , FIRST_VALUE (sale_date) OVER ( PARTITION BY product_id ORDER BY count_sold DESC , sale_date DESC ) AS high_sales_date FROM table_x;If you would post INSERT statements for your data, then I could test it.
Focus issue: Why use FIRST_VALUE with descending order and not LAST_VALUE (ASCending) ORDER of default?

THE OUTPUT IS
Kindly help me as to why the function returns invalid, it is not in the select statement, even if the value is valid.LDKB FOUND INVALIDThe problem is in your definition of the table...
CREATE TABLE VEHICLE_CLASS(VEHICLE_CLASS CHAR(2),CAR_LD VARCHAR2(50)); INSERT INTO vehicle_class VALUES('K','130 STANDARD'); CREATE TABLE VEHICLE_BODY(V_BODY CHAR(2),CAR_LD VARCHAR2(50)); INSERT INTO vehicle_body VALUES('B','3 DOOR STATION WAGON');Your vehicle_class and v_body are defined as CHAR (2) so when you insert the value 'B' and 'K' in those he's filling them with spaces to 2 characters.
Best bet is to avoid using TANK in your table definitions, unless you use only single character flags (for example, CHAR (1)) in which case it will not have adverse and simply stick to use instead of VARCHAR2.

I have a HP G60 554 CA most of the time of love - need help with the functions of the keyboard.
On my HP G60 554 CA, I do a lot of accounting/bookkeeping. Suddenly, I have no idea what I did but my alphabet keyboard turns suddenly to the BLUE character on the key of the alphabet. For example - the question mark & / key (white color) is equivalent to using the blue French E and e I know it's to do with the FN or fn key but I don't know how to tell Bank to regular.

Need help with the function MAX Returns the values
I am creating a report to return slow movement inventory data. One of the requests is that it return only the last date that an item is traded on. A map shows the last date of receipt for a part, the other will show the last time, a part has been issued or shipped on a sales order.
The hiccup is that it returns every single of the last time that an item has been received, so every last show of the material (on the second sheet) of items on-site.
Could someone help me set the max value? As shown below, and many variations, the sheet comes up with no corrupt data or dates.
MAX (Date of the MAX operation) (PARTITION OF matter Transactions.Item matter Transactions.Item ORDER)
Always returns the next two when in reality, I want just the one with the date the most recent (April 2010).

Thank you for your help.
BeckaHi Becka
If you have a new calculated column showng, as in your example, 13 April 10, and you have another column that contains also this date, you should be able to create a new condition. Condition that must be the date calculated max is equal to the actual date, thus returning only the line that includes 13 April 10.I hope I'm makng sense
Best wishes

Need help with analytical function (LAG)
The requirement is as I have a table with described colums
col1 County flag Flag2
ABC 1 Y Y
XYZ 1 Y Y
XYZ 1 O NULL
xyz *2* N N
XYZ 2 Y NULL
DEF 1 Y Y
DEF 1 N NULL
To get the columns Flag2
1 assign falg2 as indicator for rownum = 1
2 check the colm1, count of current line with colm1, Earl of the previous line. The colm1 and the NTC are identical, should assign null...
Here's the query I used to get the values of Flag2
SELECT colm1, count, flag
BOX WHEN
LAG(Count, 1,null) OVER (PARTITION BY colm1 ORDER BY colm1 DESC NULLS LAST) IS NULL
and LAG(flag, 1, NULL) PLUS (SCORE FROM colm1 ORDER BY colm1, cycle DESC NULLS LAST) IS NULL
THEN the flag
END AS Flag2
FROM table1
but the query above returns the o/p below which is false
col1_ County flag Flag2
ABC 1 Y Y
XYZ 1 Y Y
XYZ 1 O NULL
xyz *2* N NULL
XYZ 2 Y NULL
DEF 1 Y Y
DEF 1 N NULL
Thank you
Published by: user9370033 on April 8, 2010 23:25Well, you have not enough explained your full requirement in this
1 assign falg2 as indicator for rownum = 1
2 check the colm1, count of current line with colm1, Earl of the previous line. The colm1 and the NTC are identical, should assign null...as you say not what Flag2 must be set on if com1 and cnt are not the same as the previous row.
But how about this as my first guess what you mean...
SQL> with t as (select 'abc' as col1, 1 as cnt, 'Y' as flag from dual union all 2 select 'xyz', 1, 'Y' from dual union all 3 select 'xyz', 1, 'Y' from dual union all 4 select 'xyz', 2, 'N' from dual union all 5 select 'xyz', 2, 'Y' from dual union all 6 select 'def', 1, 'Y' from dual union all 7 select 'def', 1, 'N' from dual) 8 -- END OF TEST DATA 9 select col1, cnt, flag 10 ,case when lag(col1) over (order by col1, cnt) is null then flag 11 when lag(col1) over (order by col1, cnt) = col1 and 12 lag(cnt) over (order by col1, cnt) = cnt then null 13 else flag 14 end as flag2 15 from t 16 / COL CNT F F --- ---------- - - abc 1 Y Y def 1 Y Y def 1 N xyz 1 Y Y xyz 1 Y xyz 2 Y Y xyz 2 N 7 rows selected.

Need help with Group functions
I'm a total novice with SQL, so please forgive me if the answer to my question seems to be too obvious
I work with diagrams of the sample (in particular with the employees table):
DESC employees;
result
What I have to do is select all the managers, including the number of subordinates is higher than the average number of subordinates of managers who work in the same Department. What I've done so far is as follows:
SELECT mgr.employee_id manager_id, Director of mgr.last_name, mgr.department_id, COUNT (emp.employee_id)
Employees emp employees JOIN Bishop
ON emp.manager_id = mgr.employee_id
GROUP OF mgr.employee_id, mgr.last_name, mgr.department_id
ORDER BY mgr.department_id;
result
As you can see, I'm almost done. Now, I need only to calculate the average of the result of the COUNT function for each Department. But I'm totally stuck at this point.
All advice?Hello
Welcome to the forum!

All advice?Yes, you're almost done. You just need to add one more condition. You have to calculate the average value of total_cnt (the COUNT (*) you already do) of a Department and compare that to total_cnt.
There are several ways to do this, including
a scalar subquery (in a HAVING clause)
(b) make a result set with one line per Department, containing the average_cnt and reach than your current result set
(c) analytical functions. Analytical functions are calculated after the GROUP BY clause is applied and aggregate functions are calculated, it is legitimate to say "AVG (COUNT (*)) MORE (...)").If thinking (c) is the simplest. It involves the use of a query of Tahina, but (a) and (b) also require subqueries.
This sounds like homework, so I'll do it for you.
Instead, here is a very similar problem with the hr.employees table.
Let's say that we are interested in total wages given each type of work in each Department.SELECT department_id , job_id , SUM (salary) AS sum_sal FROM hr.employees GROUP BY department_id , job_id ORDER BY department_id , job_id ;Results:
DEPARTMENT_ID JOB_ID SUM_SAL ------------- ---------- ---------- 10 AD_ASST 4400 20 MK_MAN 13000 20 MK_REP 6000 30 PU_CLERK 13900 30 PU_MAN 11000 40 HR_REP 6500 50 SH_CLERK 64300 50 ST_CLERK 55700 50 ST_MAN 36400 60 IT_PROG 28800 70 PR_REP 10000 80 SA_MAN 61000 80 SA_REP 243500 90 AD_PRES 24000 90 AD_VP 34000 100 FI_ACCOUNT 39600 100 FI_MGR 12000 110 AC_ACCOUNT 8300 110 AC_MGR 12000 SA_REP 7000Now suppose we want to find out which of these sum_sals is higher than the average sum_sal of his Department.
For example, in detriment 110 (near the end OIF the list) there two types of work (AC_ACCOUND and AC_MGR) that have sum_sals of 8300 and 12000. The average of these two numbers is 10150, so we selected AC_MGR (because its sum_sal, 12000, is superior to 10150, and we do not want to include AC_ACCOUNT, because its sum_sal, 8300, is less than or equal to the average of the Department.
In departments where there is only one job type (for example, Department 70, or null "Department" at the end of the list above) the only sum_sal will be the average; and because the sum_sal is not greater than the average, we want to exclude this line.Let's start with the calculation of the avg_sum_sal using the analytical function AVG:
SELECT department_id , job_id , SUM (salary) AS sum_sal , AVG (SUM (salary)) OVER (PARTITION BY department_id) AS avg_sum_sal FROM hr.employees GROUP BY department_id , job_id ORDER BY department_id , job_id ;Output:
DEPARTMENT_ID JOB_ID SUM_SAL AVG_SUM_SAL ------------- ---------- ---------- ----------- 10 AD_ASST 4400 4400 20 MK_MAN 13000 9500 20 MK_REP 6000 9500 30 PU_CLERK 13900 12450 30 PU_MAN 11000 12450 40 HR_REP 6500 6500 50 SH_CLERK 64300 52133.3333 50 ST_CLERK 55700 52133.3333 50 ST_MAN 36400 52133.3333 60 IT_PROG 28800 28800 70 PR_REP 10000 10000 80 SA_MAN 61000 152250 80 SA_REP 243500 152250 90 AD_PRES 24000 29000 90 AD_VP 34000 29000 100 FI_ACCOUNT 39600 25800 100 FI_MGR 12000 25800 110 AC_ACCOUNT 8300 10150 110 AC_MGR 12000 10150 SA_REP 7000 7000Now all we have to do is to compare the sum_sal and avg_sum_sal columns.
Given that the analytic functions are calculated after the WHERE clause is applied, we cannot use avg_sum_sal in the WHERE clause of the query, even where it has been calculated. But we can do that in a subquery; Then, we can use avg_sum_sal in any way that we love in the Super-requete:WITH got_avg_sum_sal AS ( SELECT department_id , job_id , SUM (salary) AS sum_sal , AVG (SUM (salary)) OVER (PARTITION BY department_id) AS avg_sum_sal FROM hr.employees GROUP BY department_id , job_id ) SELECT department_id , job_id , sum_sal FROM got_avg_sum_sal WHERE sum_sal > avg_sum_sal ORDER BY department_id , job_id ;Results:
DEPARTMENT_ID JOB_ID SUM_SAL ------------- ---------- ---------- 20 MK_MAN 13000 30 PU_CLERK 13900 50 SH_CLERK 64300 50 ST_CLERK 55700 80 SA_REP 243500 90 AD_VP 34000 100 FI_ACCOUNT 39600 110 AC_MGR 12000 -
