Query that returns number 1 - Add additional columns based on percentages
I have a query that returns a large number. The return value will always be a single field (a column, a line, a single value).
I need to have also three other columns in the return of this request: one that returns a number that is 50% of the original number, one that returns a number that is 75% of the original number, and one that is double the original number. How is that possible? If anyone can point me to examples, it would be a great help. I got the results mixed by searching, so I'm not sure good practices.
Thank you for the input in advance.
Hello
Whenever you have a question, please post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and the accurate results you want from this data, so that people who want to help you can recreate the problem and test their ideas.
Explain, using specific examples, how you get these results from these data.
If you show what you want to do using commonly available tables, like those of the scott schema, then you don't need to display the sample data; just results and explanations.
Always say what version of Oracle you are using (for example, 11.2.0.2.0).
See the FAQ forum: Re: 2. How can I ask a question on the forums?
I'm not sure that understand the question.
If x is a number, then
.50 * x is 50% of this number,
.75 * x is 75% of that number, and
2 * x is to double this figure.
You can get them all in the same query, if you want to. For example:
SELECT ename
sal
.50 * sal AS p_50
.75 * sal AS p_75
2 * sal AS dbl
FROM scott.emp;
Output:
ENAME SAL P_50 P_75 DBL

Need help to write a MySQL query that returns only the peer matching records
Because I don't know how to explain it easily, I use the table below as an example.
I want to create a MySQL query that returns only the records that match counterparts where 'col1' = 'ABC '.
Notice the ' ABC / GHI' record does not have a Counter-match ' GHI / ABC' record. This record must not be returned because there is no Counter-Party correspondent. With this table, the ' ABC / GHI' record should be the one returned in the query.
How can I create a query that will do it?

R12 payment process Request Status Report add additional columns to the XML data.
In 11i, we had modified the preliminary report of payment to include additional columns (distributions of invoice). R12, this report is obsolete and Oracle introduced a new report 'Payment process Request Status Report'. This query uses BI Publisher to generate the release of the final report. I can't edit the template for the output XML to the report has not
contains data for distribution invoice account. We need to know how we can modify the XML data to include additional columns.
For the disbursement of funds (payment instructions file) process, Oracle provides extensibility IBY_FD_EXTRACT_EXT_PUB package to build the custom XML element structure that can be added to the extracted XML payment generated by the Oracle payments. Do we have something similar to this report? Are there other options available?
Thank youHello
The same "IBY_FD_EXTRACT_EXT_PUB" package also works for the payment request process status report. Please add the logic to get the distribution data in this package, and you'll see the new XML tags in this report also.
I hope this helps.

I have two tables (2) RESULT TAB (1)
CREATE TABLE TAB
(
NUMBER OF SNO
A NUMBER,
B THE NUMBER.
NUMBER OF THE SUM
);
CREATE AN ARRAY OF RESULT
(
NUMBER OF SNO
NUMBER OF THE SUM
)
my doubt is:
(1) I want to insert a table TAB, my question is how to insert a column to the SUM using the column A AND B... Here im adding two values of the column and store result in the AMOUNT column.
SNO A B SUM
1 100 150 250
2 300 100 400
I want to like this, it is possible with single insert query?
(2) at the time of the insertion TAB of values that SNO, and the values of table TAB $ insert in the table of RESULTS... is it possible these two inserts at the same time?
in fact, im using another this table.fro TAB and easy to understand I write like that, please solve this problem
First, you post in the wrong forum as this one is only for Oracle's SQL developer tool. So you might ask your question in the general forum of SQL.
Second, you might solve your problems with bind variable:
Insert tab
(sno, a, b, sum)
values
(: SNO,: A: B: A + B :))
You should not use sum as column name because it is a reserved word.
More you cannot insert into two different tables with a single SQL, but you can use PL/SQL to do this:
Start
insert into tab values (: SNO,: A: B: A + B :);)
insert into result values (: SNO,: A + B :);)
end;
If you meet sno from a sequence, you could do something like this:
Start
insert into values tab (seq_sno.nextval,:,: B,: A +: B) return sno in: SNO.
insert into result values (: SNO,: A + B :);)
end;
Hope that helps,

Help turn the query that returns single return system
Hello, I have two tables, readings, and values. Values have a foreign key to the readings.
The point and datereadings columns have the same value of related rows.create table readings ( id number primary key, point number, datereading date ); create table reading_values ( id number primary key, counter_nr number, point number, reading_id number, datereading date, CONSTRAINT fk_reading FOREIGN KEY (reading_id) REFERENCES readings (id) );
Now I have the procedure which the entry: p_point and p_date.insert into readings values (1, 1234, to_date('20100622 12:12', 'yyyymmdd HH24:MI')); insert into reading_values values (1, 0, 1234, 1, to_date('20100622 12:12', 'yyyymmdd HH24:MI')); --row1 insert into reading_values values (2, 1, 1234, 1, to_date('20100622 12:12', 'yyyymmdd HH24:MI')); --row2 insert into readings values (2, 1234, to_date('20100623 12:12', 'yyyymmdd HH24:MI')); insert into reading_values values (3, 0, 1234, 2, to_date('20100623 12:12', 'yyyymmdd HH24:MI')); --row3 insert into reading_values values (4, 1, 1234, 2, to_date('20100623 12:12', 'yyyymmdd HH24:MI')); --row4 insert into readings values (3, 1111, to_date('20100621 12:12', 'yyyymmdd HH24:MI')); insert into reading_values values (5, 0, 1111, 3, to_date('20100623 12:12', 'yyyymmdd HH24:MI')); --row5
so I want the previous reading_values (in time based on p_date) for a certain point p_date. I hope this makes sense?select * from reading_values rv, (select * from (select id, datereading from readings where datereading < p_date and point = p_point order by datereading desc) where rownum <= 1) t where rv.reading_id = t.id
Example:
Now, what I want to do, is replace p_point and p_date with two collections. For example: p_points = [1234, 1111] p_dates = [20100622 15:12, 20100624 12:12]select * from reading_values rv, (select * from (select id, datereading from readings where datereading < to_date('20100624 12:12', 'yyyymmdd HH24:MI') and point = 1234 order by datereading desc) where rownum <= 1) t where rv.reading_id = t.id returns row 3 and 4
Here, I want to have the previous reading_values by point = 1234 and datereading < 20100622 order 15:12 by datereading (where rownum < = 1).
and also reading_values by point = 1111 and datereading < 20100624 order 12:12 by datereading (where rownum < = 1).
This should return line1, line2 and row5...
So far I came up with this. But I can't be sure that it is correct. And the performance seems to be horrible (cost 88, 13 recursive calls, 155 becomes uniform) for a query with 2 entry points and 2 dates compared to the original to just a single point query and the date of entry (cost 13, 1 recursive call and gets 14 coherent).
code for creating table 1 that I used instead of collections of entry:Select rv.* from (SELECT r.id FROM Readings r, (select rownum rn1, t1.id from table1 t1 order by id) t1, -- input parameter1 (point collection) (select rownum rn2, t2.date_now from table1 t2 order by id) t2 -- input parameter 2 (date collection) WHERE r.point = t1.id AND r.datereading = (SELECT max(r2.datereading) FROM Readings r2 WHERE r2.point = t1.id AND r2.datereading < t2.date_now AND rn1 = rn2) ) r, Reading_Values rv where r.id= rv.reading_id;
Hope someone can help me on my way :) Please ask if something is unclear or strange! Thank you!create table table1 ( id number not null primary key, date_now date not null ); insert into table1 values (1234, to_date('20100622 15:12', 'yyyymmdd HH24:MI')); insert into table1 values (1111, to_date('20100624 12:12', 'yyyymmdd HH24:MI'));

Query that returns only certain fields in Java
Currently I use a filter that identifies certain keys, then get all the keys and get a unique value of each object. The rest of the object is important enough. I've seen references to the passage on the ability to do it, using CohQL, but I can't run Java.
Basically, I want to do: "select the"Cache"box where key ="asdf '" I just want back the specific 'field' rather than the entire object. How can I do this?
Thank you.Hi user13279246,
You can do this by using the ReducerAggregator. Your code would look like:
Filter filter = QueryHelper.createFilter(...); ValueExtractor extractor = new ReflectionExtractor("isReadOnly"); Map mapResult = cache.aggregate(filter, new ReducerAggregator(extractor));
The mapResult will be indexed by the actual cache keys, but the values will be extracted Boolean property.
If you need to return a number of "columns", you would use the MultiExtractor instead. In this case, each value in the returned map would be a list of corresponding extracted properties.
Kind regards

Oracle BPM 12.2.1 workspace how to add additional columns to the DB table tasklist
Hi all
I need to add some required columns to the table from the list of tasks (for example, activity and status of the activity referred to in the task line), I decompiled adflibTaskListTaskflow.jar and found a class named TaskModel.class in this package: oracle.bpel.worklistapp.tasklist.beans.model, if decompile you this class, you can see that at the table from the list of tasks, data are expressed here by using ITaskQueryService now how more columns may add other tables or is there another easier solution?
Hi Hadi,
You can add columns to your table of task list in the workspace by changing the current view, or even create a new (more and icons in pencil). The situation of activity is available in the list of columns.
You can also add columns to the list view based on flexfields tasks that you create.
If you manually change the adflibTaskListTaskflow.jar you can have problems in the future given that libraries can change between versions and of course are not recommended to do.
I have add columns to the list of tasks, and at that time here, we have created a list of custom task based on BPM Middleware. If you follow this method, you will have complete freedom to show what you want.

Looping on a method that returns a query
Hello
I have a method that returns a query, I convey in this method, an identification number, the query uses in where clause. Now I have another query that returns a list of identification numbers that I have to loop through the appellant the first method and passing in the ID number, for example
methodA
Browse the methodA results
Call methodB passing methodA.ID
results of methodB
close the loop
now, the problem I have is that methodB returns a query and I want to be able to return the results of methodB as a unique query structure. I don't know how many times I will do a loop through the results of methodA, maybe twice, he could by ten times. Thus, the results of calling methodB could be very large.
How can I add methodB results in a single query structure?
I finally had to create a monster query with joins in about three tables, but it works.

Assuming that you want to add the column to capture valid or not valid and store it in the database, if this is the case.
1 Add this column that will contain the values for valid and invalid in the table to your query in a table
Here I added the status column that will keep VALID and INVALID in the database
select "EMPNO", "ENAME", "JOB", "MGR", "STATUS" from EMP
2. go to the attributes of the region-> column to change the STATE of

Display as-> list of selection (named LOV)
Named LOV-> select your Lov

Reference Table name-> the name of the table
