Help - Tuning query based on the status column

Hello
I have a query in which I need to fetch records based on values in the status column. It can contain the values 'A' and 'P '. A record can have an "A" record and a record of 'P '. My conditions are,
(1) when it is only 'A' record, can return 'A' record.
(2) for the 'A' and 'P' folder is there, then return 'A' record.
(3) when 'P' registration is only, then return 'P' registration.
There are about 3 records 'A' Lake and 3K 'P '. I tried to use 'by' clause queries, but performance are too bad and I am not able to use it. When running as independent queries 'A' retrieval of documents is faster compared to the records of 'P '. When running in 'by' clause of the query is suspended. Please can anyone help how can be managed?

Due to restrictions, I won't be able to view the actual code. I post here a sample.

Example code:

WITH q1 AS
     (SELECT *
        FROM tab
       WHERE status = 'A'),
     q2 AS
     (SELECT *
        FROM tab
       WHERE status = 'P'),
     q3 AS
     (SELECT *
        FROM q1
      UNION ALL
      (SELECT *
         FROM q2
        WHERE NOT EXISTS (SELECT 1
                            FROM q1)))
SELECT *
  FROM q3
 WHERE ROWNUM < 501;

Thank you

One way is to use analytics like this:

SELECT *
FROM (SELECT t.*, ROW_NUMBER() OVER (PARTITION BY 
                                     ORDER BY t.status) rn
      FROM tab t
      WHERE t.status IN ('A', 'P'))
WHERE rn = 1

Different line colors based on the status of my order
Hello

I created a jspx page in my application. For the table, I want to display different color lines, based on the status of the order.

When the State is new, I want to display in red. When the command is in progress, I want orange. approved in yellow, green and finished in grey for shipping.

How can I achieve this?

Thank you
Hello

Sorry, there was a typing error in my previous answer. You need to compare with 'In PROGRESS' and not 'INPROGRESS '.

That is to say, the column should look like.
```
  <== Changed INPROGRESS to IN PROGRESS

IOM sql Query to get the status of the failed task
Hello world

We have an obligation as we need to get the status of a particular task (say Create User in OID - Completed\Rejected status resource) for the particular user. We are able to get the status of the provisioed of resources to the user but not the status of the special mission which is trigerred for the user.can someone put some light on it.

Thank you

Hi, Abe,

You are on the right track, using ROW_NUMBER to assign numbers and pick-up only #1 in the main query. The main thing you're missing is the PARTITION BY clause.
You want to assign a #1 for each distinct combination of group_id, path, assets and calendar day , right?
Then, you need to PARTITION BY group_id, path, assets and calendar day . I think you understand that when you called this thread "query based * on partition date."

The next thing is the controlling ORDER BY clause. To know which line of each partition is assigned #1, you must order the lines of result ("Success" first, then "Failed") and after that, of jobdate (jobdate last first, which is in descending order).

If so, that's what you want:

WITH     got_r_num     AS
(
     SELECT  j.*     -- or list columns wanted
     ,     ROW_NUMBER () OVER ( PARTITION BY  group_id     -- GROUP is not a good column name
                               ,                    path
                         ,             asset
                         ,             TRUNC (jobdate)
                               ORDER BY          CASE  outcome
                                             WHEN  'Succcess'
                                     THEN  1
                                     ELSE  2
                                         END
                         ,             jobdate     DESC
                       )      AS r_num
     FROM    job_table  j
     WHERE     outcome     IN ('Success', 'Failed')
--     AND     ...     -- Any other filtering, if needed
)
SELECT     *       -- or list all columns except r_num
FROM     got_r_num
WHERE     r_num     = 1

If you would care to post CREATE TABLE and INSERT instructions for the sample data, and then I could test it.

How can I set the color of a specific cell (or column) based on a hidden column?

A column containing a hexadecimal value of the color does not look good...

Specify the color of cell required using the hidden column and a data attribute to the property Expression of HTML in the column:

#VISIBLE_COLUMN_ALIAS#

Apply a static ID of the visible column to serve as a selector, jQuery, and you can access the invisible color value in your JS code in dynamic action to run the JavaScript Code using the dataset property.

Is this ?

Run one or the other query based on the result

Hi all

Is there anyway that I can design this query to run only a subquery based on the returned results.

select to_char((NEXT_CHANGE# - 1),9999999999999999) latest_change 
from v$archived_log 
where SEQUENCE# =(select nvl(min(SEQUENCE#),0) 
                               from v$archived_log 
                               where ARCHIVED='YES' 
                               and APPLIED='NO')

If the above subquery returns 0, then I would like to execute the query below. Is there any way to embed multiple queries like case conditions ?

select max(SEQUENCE#) 
                               from v$archived_log 
                               where ARCHIVED='YES' 
                               and APPLIED='YES'

Thank you

G

Hello
Use the operator to decode your subquery:

Select to_char ((NEXT_CHANGE #-1), 9999999999999999) latest_change
v $ archived_log
where SEQUENCE # = decode ((select nvl (min(SEQUENCE#), 0)))
v $ archived_log
When ARCHIVED = 'YES '.
and APPLIED = 'NO'),
0,
(select max(SEQUENCE#)
v $ archived_log
When ARCHIVED = 'YES '.
and APPLIED = 'YES'),
(select nvl (min(SEQUENCE#), 0))
v $ archived_log
When ARCHIVED = 'YES '.
and APPLIED = 'NO'));

IF NEW VARIABLE in SQL QUERY, DISPLAYS as the LAST COLUMN + rpad does not
Hello all and thanks in advance.

(1) if I add a new variable to my sql query to select a column, which was already on the table, it shows it in the report of the table as the last column on the right. In other words, if I add "the street" to

something like city, postal code, street, store, Manager, etc., instead of placing the Street between CP and the Bank, the place like I said as the last column on the right.

(2) when the values entered in the cells of the tables, Yes, they extend to their length, but, only if it is a Word. If it is two, as when I enter the value of 'very good '.

then two lines as well as by a newline within the cell, for example, which in fact too high the rank. I tried sdap spaces with rpad but this did not work. something like rpad (stock, 20,' ')

I have to say that the table is in the same page where there is a form, as the table grows in length it's actually squeezing the form on the left.

(3) rpad did not work with the simpler syntax, but less would be with what I need, because it turns out that I am using DECODE to perform a conversion between the displayed value and

value returned in my select list of values, something like: DECODE (TO_CHAR (stock), '1', 'Black', '2', 'Average', '3', 'good', '4', 'Very good', null) AS stock

so, I tried to put the rpad there in several places, but either he gave the parse error or it has left empty do not pick up all the values in the column.

Thank you very much

Alvaro
Alvaro

(1) this is the standard behavior of the constructor of the apex. You can change the order of display with arrows in the report column attributes.

(2) you have to play with the style of the column attributes to accomplice this. For the style of the instance = "" white-space: pre; ' in the attributes of the element column attributes. " White-space: normal would be put on several space (' ') 1. So no matter how you add with rpad, they will display as 1.
Set a width or as attribute in a class style for this column.

Hgrid amount format based on the currency column
Hello

I am trying to format columns hGrid based on the currency amount. I checked the old nets and tried, but it did not work. I do not know which API to use to get the item correctly format. All ideas are welcome.

Thank you

Alka
Hi AlkaT,

What exactly are you trying to achieve? you try to format a NUMBER type item in the currency of the system? If so the bottom of piece of code should work fine, just put in your controller processRequest() method:

{} public processRequest Sub (pageContext OAPageContext, OAWebBean webBean)
...
OAMessageStyledTextBean currencyField = (OAMessageStyledTextBean) webBean.findIndexedChildRecursive ("CurrencyFieldItem");
currencyField.setAttributeValue (CURRENCY_CODE, "AUD"); / * Replace the currency of your country instead of AUD * /.
...
}

Help on query: how to produce from columns of ranks?

B2      34     55     0     3     4     0
B3      99      0     0     0     0     1

The problem here is that we can have multiple status codes, so as a result the query should return dynamically the number of columns

Is it possible to produce above output? Any help will be appreciated.

Oracle DB Version - Oracle 8i

Thanks in advance!

Hello

This is called a pivot .
The basic technique is something like:

SELECT     item
,     SUM (CASE WHEN state = 'MS'  THEN value ELSE 0)     AS ms
,     SUM (CASE WHEN state = 'GOA' THEN value ELSE 0)     AS goa
,     SUM (CASE WHEN state = 'UP'  THEN value ELSE 0)     AS up
,     SUM (CASE WHEN state = 'PB'  THEN value ELSE 0)     AS pb
,     SUM (CASE WHEN state = 'DL'  THEN value ELSE 0)     AS dl
,     SUM (CASE WHEN state = 'TN'  THEN value ELSE 0)     AS tn
FROM     table_x
GROUP BY  item;

but this requires you to know indicates how many there are, and what they are, when you write the query.

Since you have not, you must run a preliminary motion that will generate a select like the one above, or at least SUM expressions for variable columns. This is called dynamic SQL code , and a technique to do this is included below. (The example uses COUNT, but any aggregate, including the SUM function, work).

Another possibility is the aggregation of the chain, where instead of individual columns for each State, you have a huge column VARCHAR2, formatted to look like separate columns. The avaiable tools to do this in Oracle 8.1 are quite poor, however, so I think you're better with dynamic SQL.

/*
How to Pivot a Table with a Dynamic Number of Columns

This works in any version of Oracle
The "SELECT ... PIVOT" feature introduced in Oracle 11
is much better for producing XML output.

Say you want to make a cross-tab output of
the scott.emp table.
Each row will represent a department.
There will be a separate column for each job.
Each cell will contain the number of employees in
     a specific department having a specific job.
The exact same solution must work with any number
of departments and columns.
(Within reason: there's no guarantee this will work if you
want 2000 columns.)

Case 0 "Basic Pivot" shows how you might hard-code three
job types, which is exactly what you DON'T want to do.
Case 1 "Dynamic Pivot" shows how get the right results
dynamically, using SQL*Plus.
(This can be easily adapted to PL/SQL or other tools.)

NOTE: Using SQL*Plus file I/O, as in this example, is just

/*
EXPLANATION:
The basic pivot assumes you know the number of distinct jobs,
and the name of each one.  If you do, then writing a pivot query
is simply a matter of writing the correct number of ", COUNT ... AS ..."\
lines, with the name entered in two places on each one.  That is easily
done by a preliminary query, which uses SPOOL to write a sub-script
(called dynamic_pivot_subscript.sql in this example).

The main script invokes this sub-script at the proper point.
In practice, .SQL scripts usually contain one or more complete
statements, but there's nothing that says they have to.
This one contains just a fragment from the middle of a SELECT statement.

Before creating the sub-script, turn off SQL*Plus features that are
designed to help humans read the output (such as headings and
feedback messages like "7 rows selected.", since we do not want these
to appear in the sub-script.
Turn these features on again before running the main query.

Result of the query based on the form of the parameter
Good morning people. I really couldn't come up with a smart enough subject line, but I'll try and make up the body.

I currently have a report that accepts parameters on the parameter form. They are extra employees and Number of Copies. The employee ID is stored in the Employee table, but the number of copies is not.

The output of the report shows all the different addresses and phone numbers, the employee a. lets say, Employee ID 0001 has two addresses - home and office. In the report of my request, he'll give me two records in the repeating group. However, I have another parameter and the ID of the employee who is the number of Copies. In this case, if the number of Copies to be printed is 1, so it isn't a problem. However, if the Number of Copies is entered by the user is 4, I think in this case 4 x 2 = 8 pages of report output (4 with the address of the House) and 4 with the address of the office.

I know there is a way to do this using a temporary table in AfterPForm and then using the results of the query by joining my request to the temporary table, but I was really hoping to avoid this situation if it can be treated through the query.

Main request:
```
SELECT    e.emp_no,
          e.saln||e.first_name||' '||e.last_name emp_name,
          a.street,
          a.city||' '||a.province||' '||a.postal_code city,
          '('||a.tel_area||') '||a.tel_number telephone
FROM      employee e, emp_address a
WHERE     e.emp_no = a.emp_no
AND       e.emp_no = :P_EMP_NO;
```
Any help is appreciated. Thank you!

Report, SQL query based on the values of the elements (question SQL)

Hello

I use APEX 4.0 with Oracle 10 g r2 under Windows XP Pro SP3.

I have an interactive report and a menu with a few items to filter the report.

It works with most of the elements, but my problem is to select lists that have additional values, for example:

SELECT '(null)' display_value, 'NULL' return_value FROM DUAL
UNION ALL
select distinct(SPAT_AREA_NAME) display_value, SPAT_AREA_NAME return_value 
from SPATIAL_POINTS
order by 1

and I will return null as ' (return '%').

For example, if the user selects "(null)", the report should return all rows with a NULL value in the column AREA_NAME.
If he chooses "", the report should return all the lines. "
and if the user selects a value, the report should return all the lines containing the value in column AREA_NAME.

I don't know how to build my application. I tried with the CASE statements, DECODE, etc... but I still can't!

My report query is for now:

select SPAT_ID,
 SPAT_ACCL_NAME,
 SPAT_AREA_NAME,
 SPAT_CLASS,
 SPAT_NUMBER,
 SPAT_PT,
 SPAT_TYPE,
 SPAT_STATUS,
from SPATIAL_POINTS 
where 
 upper(SPAT_AREA_NAME) LIKE upper(:P3_FILTRE_AREA_NAME)  AND
 upper(SPAT_ACCL_NAME) LIKE upper(:P3_FILTRE_ACC_NAME) AND
 upper(SPAT_CLASS) LIKE '%'||upper(:P3_SPATIAL_CLASS)||'%' AND
 instr(upper(:P3_SPATIAL_TYPE_VALUES),upper(SPAT_TYPE)) > 0 AND
 instr(upper(:P3_SPATIAL_STATUS_VALUES),upper(SPAT_STATUS)) > 0 AND
 instr(upper(:P3_SPATIAL_POINT_VALUES),upper(SPAT_PT)) > 0

Any idea?

Thank you!

Yann.

Hello

Then, assuming that spat_accl_name is not a string value "NULL" then you can try this...

SELECT spat_id,
       spat_accl_name,
       spat_area_name,
       spat_class,
       spat_number,
       spat_pt,
       spat_type,
       spat_status,
       ROUND(spat_cumul,
             (SELECT up_number_precision
              FROM   user_preferences
              WHERE  UPPER(up_nice_login) = UPPER(v('APP_USER'))))
          AS "SPAT_CUMUL"
FROM   spatial_points
WHERE  :p3_filtre_acc_name IS NULL AND spat_accl_name IS NULL
       OR(CASE
             WHEN :p3_filtre_acc_name = '%' THEN NVL(spat_accl_name,'NULL')
             ELSE :p3_filtre_acc_name
          END = NVL(spat_accl_name, 'NULL'))

See you soon
