SQL query with dynamic exercise

Hello

I wrote this query with static exercise and exercise, I need info on making the dynamic variables

Exercise: starts from July1st. This year up to June 30 is "2011" and July ' 1's '2012'
Exercise: July1st his '1' and June ' 1 his '12'

Query:

Select distinct o.c_num, o.ac_num, s.sub_ac_num, o.fiscal_year, o.ac_exp_date, s.sub_ac_ind
of org_account o
outer join left sub_account s
on o.c_num = s.c_num and o.ac_num = s.ac_num
where (o.ac_exp_date > = CURRENT_DATE or o.ac_exp_date is null)
and o.fiscal_year = * '2011' * -> need to be dynamic
and o.fiscal_period = * '12' * -> need to be dynamic

Thank you
Mano

Hi, Mano,

Welcome to the forum!

Whenever you have a question, please post a small example of data (CREATE TABLE and INSERT statements) and the results desired from these data.
Always tell what version of Oracle you are using.

Since this is your first thread, I will post some examples of data for you:

CREATE TABLE     table_x
(     dt     DATE
);

INSERT INTO table_x (dt) VALUES (DATE '2010-12-31');
INSERT INTO table_x (dt) VALUES (DATE '2011-01-01');
INSERT INTO table_x (dt) VALUES (DATE '2011-06-02');
INSERT INTO table_x (dt) VALUES (DATE '2011-06-30');
INSERT INTO table_x (dt) VALUES (DATE '2011-07-01');

What is the output you can from these data?

DT          FISCAL_YEAR     FISCAL_PERIOD
----------- --------------- ---------------
31-Dec-2010 2011            06
01-Jan-2011 2011            07
02-Jun-2011 2011            12
30-Jun-2011 2011            12
01-Jul-2011 2012            01

If so, here's a way to get it:

SELECT       dt
,       TO_CHAR ( ADD_MONTHS (dt, 6)
            , 'YYYY'
            )     AS fiscal_year
,       TO_CHAR ( ADD_MONTHS (dt, 6)
            , 'MM'
            )     AS fiscal_period
FROM       table_x
ORDER BY  dt
;

Since your exercise begins 6 months prior to the calendar year, you must add 6 months to the actual date for the fiscal year and month.

The above query produces strings for fiscal_year and fiscal_period. If you prefer to have the numbers, then use EXTRACT instead of TO_CHAR:

SELECT       dt
,       EXTRACT (      YEAR
            FROM     ADD_MONTHS (dt, 6)
            )     AS fiscal_year
,       EXTRACT (      MONTH
            FROM     ADD_MONTHS (dt, 6)
            )     AS fiscal_period
FROM       table_x
ORDER BY  dt
;

The first query will work in Oracle 6 (and more).
I don't know when EXTRACT was introduced. Certainly, it works in Oracle 10 and may be available in older versions too.

  • More than 1 SQL query with checkbox and error invalid number report

    Hi all

    I have two SQL query reports that each has an apex_item.checkbox and two processes for each report.  A report/process works very well.  It gives me an error of invalid number.

    In addition, another query SQL (editable report) gives me the following error when using the Multi line process, delete.

    ORA-06502: PL/SQL: digital or value error: character number conversion
    error ORA-06502: PL/SQL: digital or value error: character number conversion
    error
    Ok

    When I got a report from SQL query (with box and a process) and the query SQL (editable report) everything worked.  It stopped working when I added another SQL query report (with box and a process).

    A SQL query has the following in my query: apex_item.checkbox(3,email_id,'UNCHECKED') ""

    The other SQL query has the following: apex_item.checkbox(2,b.file_id,'UNCHECKED') ""

    Any help will be greatly appreciated,

    3. There are undesirables who should be ignored

    Once again my thought process is that we join the activity and 4 alias table lonet.

    ask for your help in this

    This is called pivoting.

    WITH relevant_data AS

    SELECT a.project_wid, a.project_no, b.SID

    , l.name AS lonet_name, l.entryvalue

    Activity one

    LEFT OUTER JOIN lonet l.root = a.project_wid l

    PIVOT (MAX (entryvalue)

    FOR lonet_name IN ("GAC" IN the gac

    "NAM" AS nam

    'BAG' IN the bag

  • SQL query with terms and calculations?

    Hello
    How do I create a query with terms and calculations?
    For example, I have this table


    Start | End |     At work |     Mandatory

    1ST JANUARY 13 | JANUARY 11, 13.     Office |          1

    Now, if the workplace of the column = office and required column = 0
    the new 'price' column should calculate: (end-start) * $25.00
    and if workplace = Office and required column = 1
    the 'price' column must calculate: (end-start) * $20.60
    any other $0.00

    I tried with the case statement, but I didn't know how
    to calculate my values and display in the virtual column 'price '.

    Something like
    case

    Hi guys, I'm on JDev 11.1.1.7.0 and have a usecase where I use a valueChangeListener on a selectOneChoice to dynamically set a pageFlowScope on the search box in the pageDef. The viewcriteria have different criteria and labels for the viewcriteriaitems in the resource group, so I will try to make the dynamic searchRegion. In a previous situation, I used https://blogs.oracle.com/groundside/entry/towards_ultra_reusability_for_adf to use a dynamic iterator.

    The problem I encounter is that the searchCountryCriteriaquery is not updated with the criteria for good. I watched Luc Bors Weblog: ADF 11 g: query component with the criteria of 'dynamic' view, but in this usecase, the user must click a button prior to loading of the search screen. In my case, I want the user to select the criteria through the selectOneChoice so on the page. I tried to see if I could refreshing the searchRegion and the related queryPanel.

  • SDO_RELATE within PL/SQL query with rownum clause runs slowly on 12 c - works great on 10 g

    Hello

    I use the database 12.1.0.2 with a node 2 RAC on Windows.

    I am struck by a really weird performance problem with a particular query.  Bear with me while I try to explain...

    I have a chart with lines 30 sdo_geometry million, in 7 partitions with a local partitioned spatial index divided.  Called BIG_PARTITIONED_TABLE for this example.

    I query the table to search for one line with a geometry that is equal to the geometry of my request.  In this case I use sdo_relate with "mask = equal".  Instantly returns:

    Here is a comparison of the plans to explain.  First, here's the good thing, that is using the spatial index (BIG_PARTITIONED_TABLE_SPIND):

    select id, GEOMETRY

BIG_PARTITIONED_TABLE O WHERE SDO_EQUAL(O.GEOMETRY, :B1 ) = 'TRUE'
AND ROWNUM = 1

    Then the slow that does not use the spatial index.

    I tried adding an indication / * + index (o BIG_PARTITIONED_TABLE_SPIND) * / but that did not help.

    I am struck this issue during testing of upgrade 10.2.0.5 to 12.1.0.2.  The query works perfectly on 10g - we note only that this question on 12 c.

    I can't use sdo_equal as the real mask that we want is equal + dommagescausdspar + covers.  I'm just using equal here to simplify the test.

    I use "rownum = 1" because I want to just the first result.  In practice I can rewrite probably is a FOR LOOP, I get out after the first result, but that seems all just awful.

    Any ideas?  If anyone has seen anything like this before?  Its an optimizer delivers really so I'm going to cross post the SQL Forum after a certain time, but thought I would post it here first.

    Thank you

    Hi John,.

    Can you please try the following before your slow queries event?

    "ALTER session set events ' trace 54669 name context forever."

    Thank you

    Hi all

    Database version: 10.2.0.5

    I'm working on a new report to view the top users by the number of calls. The table is truncated and filled again every month with records for the previous month; It contains approximately 400 000 records.

    I created a view with the columns needed for the report; also, the two functions of view calls to determine if a phone number is assigned to multiple staffs or several departments.

    It's full again table every month:

    It's to you if you are satisfied or interested in improvements (if possible).

    If so the first thing I would like if you had your refreshed perspective as advised. According to expected area_code table cardinalities I doubt.

    So, if not cool off with dbms_stats.gather_table_stats on two tables, area_codes and MONTHLY_BILLING_DETAILS.

    Bottlenecks are now obviously the full table of MONTHLY_BILLING_DETAILS as well as the ANTI of LOOPS IMBRIQUEES scan.

    At the moment I don't think that an index of MONTHLY_BILLING_DETAILS will help a lot, because most of the lines will pass filter predicates, and because we need some columns in it, I have now I there will be gain a full index scan.

    I was surprissed that the optimizer pushes the substr <> predicates to both tables.

    So depending on your data, you might try

    1 make a factory of subquery select the two MONTHLY_BILLING_DETAILS columns that all directly apply predicates of membership and use it directly in the join instead of the table.

    or

    2. If all subtr to so are part of the table area_code choose in it using a subquery (or inline view) plant excluding these values.

    Both are attempts to get rid of the substr excluding as filters of join predicates.

    In fact, I was expecting a hash join anti as shown in the plan to explain instead of the nested loops anti, I expect to be more effective in this case.

    Perhaps with correct cardinalities the optimizier would understand himself.

    Just to test it, you can try the use_hash hint in the join:

    Select / * + USE_HASH (MBD, one) * /.

    ..

    OF MONTHLY_BILLING_DETAILS MBD,.

    NYNJ_METRO_AREA_CODES one

    (It's a good habit anyway usually use aliases and precede the names of columns. In the, it is easier to read queries are only trivial).

  • (Editable report) SQL query with line selector

    I used this code to get the update of the records in a query SQL (editable report).
    Updates a value in a selection box.

    because me in 1... apex_application.g_f01. Count
    loop
    UPDATE CONTRACTS
    SET LOAD_FLAG =: P8_SELECT
    WHERE ID = apex_application.g_f01 (i); -i'the checked the file 'primary key '.
    end loop;

    Here's my dilemma.
    Line selector seems to be in a fixed position.
    By linking the line for identification number selector (1, 2, 3, etc.)
    Sort by ID (1, 2, 3, etc.)
    It works perfectly, as long as the ID is sorted in order. < <
    If it is sorted by another field with say ID 29 now in the 1st row, by checking the box and update, you update ID #1 located elsewhere on the page.
    Any ideas how to make the line selector literally equal to the line, it is displayed in?
    Thank you
    Bob

    I think I have an idea of what is wrong and, eventually, how to fix it. Try this:

    make your field primary key (NO ROWID!) in a column in a table column, either through the "wizard" (i.e. through the report attributes screen), or using the APEX_ITEM api (as described by Vee). I often have my primary key as a hidden; If you really need to see it, you can use "DISPLAY_AND_SAVE".

    So if your primary key 'ID' colum is now in the 2nd table as a table (i.e. f02 - adjust accordingly!), your PL/SQL process should look like this:

    for i in 1 .. apex_application.g_f01.count
loop
   UPDATE CONTRACTS
      SET LOAD_FLAG = :P8_SELECT
    where ID = apex_application.g_f02(apex_application.g_f01(i)); 

end loop;

    It of a little confusing at first but it it makes sense when you train how tabular tables work with check boxes. The length of this array represents only what is verified - so if you have 3 values checked, the cardinality of the table in a particular table 3. On the other hand, your other tabular berries (containing the 'normal' values) has a cardinality of the count of all the visible lines.

    In this case, the record selector (F01) contains the ID of the relevant line in your report - so passing this value in the array index 2 (F02) should give you the correct primary key for that particular line value. If you subsequently order the report by another field, it should work again.

    I should add that Vee method will work well - the difference is that, instead of organizing the rowid, f01 contains the actual key value. Hope this helps

  • SQL query to dynamically filter the records-need help

    Hello

    I have a table with the structure as below

    Create table T1
    (Number (5) ID,)

    Here's the table of contents at different points in time and please help me with a query that must dynamically discover the results according to the entries in the table.

    First Table contents

    1 pending

    Result of the query must be

    1 pending
    2 waiting


    After an insert the Table of contents

    1 pending

    3 ignored

    Result

    Nothing should be displayed

    Result

    Thanks in advance!

    Best regards

    Hi, Sridhar,

    So you want to show t1 lines that come after the last row with action = "Ignored", which means no output at all during the last row has action = "ignored". (A line with a given id is considered as ' after' a line with a lower id. The line with the highest id is considered the "last" line.)
    Is this fair?

    Here's one way:

    SELECT     *
FROM     t1
WHERE     id  > (
          SELECT  MAX (id)
          FROM     t1
          WHERE     action     = 'Ignored'
           )
;

    It's not assume this id is whole consecutive.

    If the id is not unique, what results do you want? There is a chance that the above query is already doing if this is not the case, it can probably be changed.

  • Question - create a field in a SQL query with the status not nullable

    I want to create a field that is not nullable char (2) length

    If I do CREATE TEMPORARY TABLE X

    SELECT

    "AH" AS CDTYPE

    or

    SELECT

    CAST ('AH' AS CHAR (2)) CDTYPE

    Or

    CAST (NVL(' ','AH') AS CHAR (2)) CDTYPE

    The field is always created as a nullable field of Char (2)

    Without creating a special field type, how can I dow it

    You cannot set the projections have NOT null SQL, you can only put your query clauses so that NULL values are filtered out or by default set to another value results.

    NO NULL only applies to the columns of the table (or PL/SQL parameters/variables).

  • Difference between the static SQL query and dynamic SQL query.

    Hello

    Please explain the fundamental difference between static and dynamic sql queries. Please explain for example.

    Static: http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10472/static.htm

  • pl - sql query with indexes per table

    Hello again,

    I'm stuck with this query, I want to display the full name of all employees, using the HR schema table.

    DECLARE
    Employee_table_struct TYPE IS an ARRAY OF
    HR. Employees.first_name%type
    INDEX OF DIRECTORY;

    employee_table employee_table_struct;

    Employee_cursor CURSOR IS
    SELECT first_name
    OF hr.employees;


    v_row NUMBER: = 1;
    BEGIN

    OPEN employee_cursor;

    LOOP
    OUTPUT WHEN employee_cursor % NOTFOUND;

    DBMS_OUTPUT. Put_line (employee_table (v_row));

    -populated the next time the loop * /.
    v_row: = v_row + 1;
    END LOOP;

    CLOSE Employee_cursor;
    END;
    /

    Its gives me error saying:

    ORA-01403: no data found
    ORA-06512: at line 21

    Help, please
    Thank you

    Why not use a clear FOR the loop?
    It allows you to save saying stuff and it does the same thing, showing first_name for all employees:

    begin
  for rec in ( select first_name
               from   hr.employees
             )
  loop
    dbms_output.put_line(rec.first_name);
  end loop;
end;
