Application Express :: How To Change Column Order In Interactive Report

Oct 18, 2013

I am trying to change the column order in an Interactive Report. Run the report as a developer then use the action menu. 

However, I am not sure how one can run the the report as a developer.  Do you just login and run the page?  Then if I do that, I don't see the action menu there.  If I go to page attributes "Save Report" tab, I do see the action menu but "Select Columns" only gives me "Report Type", "Report Name" etc as columns. Or we don't have enough privileges to run the report as a developer?

Performance Tuning :: How To Change Execution Order

May 2, 2012

Performance issues with the below mentioned sql.After gone through execution plan we have found out the reason but we couldn't able to change the execution plan the way we want.

If we could able to join

HRMGR.HR_EXPANDED_BOOK table with MISBOMGR.ibm_client_mgr7_empid, MISBOMGR.ibm_client_mgr6_empid at earlier stage means before HRMGR.HR_EMP_STATUS_LOOKUP then my issue will be solved but somehow optimizer is not considering that path. Even i have added push_subq hint which will push sub queries to execute at earlier stage but no use. Why push_subq hint is not working in this scenario and what can be the other alternative to change the driving path.

Query :-

select /*+ push_subq */CEMP.EMP_ID,
CEMP.EMP_STATUS_CD,
EMP_STATUS_DESC,
MGR_6_EMP_ID,
MGR_7_EMP_ID
FROM
[code]........

PL/SQL :: How To Order By The Column

May 28, 2013

I have a varchar2 column which can hold numeric values, and also varchar2 values.

The following select returns only the records which have a number value in that column

select * from my_table
order by decode(
replace(translate(valoare,'1234567890.','00000000000'),'0',''), NULL,
valoare, 0 ) != 0;

But how can i order that column, so that first are the numbers (also ordered), and then the varchar2 columns (so all the rows of that table are selected, both varchar2 values and numbers in that column)? Is it possible?

PL/SQL :: Order By In Union Clause In Date Column

Nov 3, 2012

Oracle version : 11.2.0.2 Linux EL6 server

I have a query like below:

select col1, col2, col3, col4
from tab1, tab2, tab3
where conditions
union

[Code]...

Now, the col4 is a date column and I have to order by the entire result sets on it. I know I can do it by (order by col4) or by (order by 4) at the end of the entire query.

But the problem is that, the output is coming in dd-Mon-yyyy (i.e 31-Nov-2012).

I want every output in dd/mm/yyyy format so I need to use to_char function.

But in that case, I cant use the order by clause, because in that case it is getting arranged by character i.e by 1,2,3,4,5 like this.

PL/SQL :: Order By Date Column With A Format Mask

May 16, 2013

10g- 10.2.0

This is my query

select to_char(exp_Date,'Mon-YYYY') dt, count(*) from exp_main
where exp_type like 'Income%Photo%'
group by to_char(exp_Date,'Mon-YYYY')
order by exp_date

When I run this I get :not a GROUP BY expression

If I remove the order by, it works fine.

Is there a way to order by since the output of the query is character-sorted.

I did search online most have suggested to use order by column_name. But does not work for me.

Server Utilities :: SQL Loader - Excel File Different Column Order Format?

May 8, 2011

I have an Excel spreadsheet that just had a format change. The fourth column is new. Order of columns in Excel is:

oldcol1
oldcol2
oldcol3
oldcol4
newcol
oldcol5

Sqlldr script is in order of the .csv file just listed. Oracle table is in order

oldcol1
oldcol2
oldcol3
oldcol4
oldcol5
newcol

When I run the sqlldr script, the information is loaded:

oldcol1
oldcol2
oldcol3
oldcol4
newcol in oldcol5

so that all the information is loaded incorrectly. Out side of having to change the table, is there anything I can do to make it load correctly?

Performance Tuning :: Index Usage In Order By Clause On Nullable Column

Jan 28, 2011

I came across situation where a Nullable column is not using index for 'order by' clause. I added Not Null condition in the 'where' condition but it wasn't useful. I don't wanted to make composite index with not nullable column or with constant or modify column to 'Not Null'

So I carried out test cases and during which I found that in one case the sql statement does 'fast full scan' for data access but does not use index for 'order by' sorting

here are the steps

Initially I kept the column Nullable

SQL> create sequence s5;
Sequence created.

SQL> create table t5 as select s5.nextval id,a.* from dba_objects a where rownum<1001;
Table created.

SQL> set pages 100
SQL> select column_name,nullable from user_tab_columns where table_name='T5';

SQL> create index i5 on t5(id);
Index created.

SQL> exec dbms_stats.gather_table_stats(user,'T5',cascade=>true);
PL/SQL procedure successfully completed.
exit

SQL> alter session set events '10046 trace name context forever, level 12';

select *
from
t5 where id is not null order by id

Questions are

1) Why adding 'where id is not null wasn't enough for the index to get used in 'order by'?
2) While we got 'fast full scan' why index wasn't used for 'order by' clause?
3) Do we need the indexed column in where clause for being used in 'order by clause' too?
4) Do we need 'order by' clause if we are selecting only the indexed column with sequence generated values?

Performance Tuning :: Order Of Steps In Execution Path And Order Of Predicates In The Plan

Mar 20, 2012

Which step in the following plan is the first step of execution

I reckon it is "TABLE ACCESS BY INDEX ROWID| BANK_BATCH_STATE"

Is that correct?

In the "Predicate Information (identified by operation id):"

Isn't there any relation between the order of execution steps and the order in which predicates are displayed?

SQL & PL/SQL :: Change Column Datatype From CLOB To Varchar2

SQL & PL/SQL :: Result Order In 2 Table Joins Without Order By

Sep 6, 2011

I have below tables,

describe rpthead

Name Null Type
--------------------------- -------- -------------
RPTNO NOT NULL NUMBER
RPTDATE NOT NULL DATE
RPTD_BY NOT NULL VARCHAR2(25)
PRODUCT_ID NOT NULL NUMBER

describe rptbody

Name Null Type
------------- -------- -------------
RPTNO NOT NULL NUMBER
LINENO NOT NULL NUMBER
COMMENTS VARCHAR2(240)
UPD_DATE DATE

The fact is that we store some header in RPTHEAD and store real data in RPTBODY, the question is that if I use below SQL to query all data for a 'PRODUCT_ID'.

SELECT t0.LINENO, t0.COMMENTS, t0.RPTNO, t0.UPD_DATE
FROM RPTBODY t0 , RPTHEAD rpthead
WHERE
(
t0.RPTNO = rpthead.RPTNO
AND
t0.UPD_DATE>=to_date('1970/01/01 00:00:00','YYYY/MM/DD hh24:mi:ss')
AND
rpthead.PRODUCT_ID IN ('4647')
)

I do not want to have 'ORDER by' clause since data set is too large, the sorting takes long time, is there any way to get the result rows in the order sorted by RPTNO? We have the index for RPTNO on RPTBODY.

Application Express :: Tabular Form - Change Column Values Before MRU

Jun 4, 2013

I have a problem with Tabular form. Configuration: Oracle 10g, Application Express 4.1.0.00.32.

I have tabular form on simple table. I need to change some column values before MRU. For example: i have column named "UPDATE_DATE" where i need write SYSDATE every time this record was updated. I've created page process, associated with my tabular form.

Process point: On Submit - After Computations and Validations;
Sequence set to 1 (before "ApplyMRU" process - it has sequence 10);
When Button Pressed: Submit;
Execution Scope: For Created and Modified Rows;

Source:

declare
indx varchar2(255);
l_map wwv_flow_global.vc_map;
l_id number;
l_pk number;
begin
[code]........ 
   
But this doesn't work. MRU process writes old values, that was posted from browser. I tried change values by

apex_application.g_f04(:APEX$ROW_NUM) := sysdate;but this also not work.

How can i change values before MRU? Why wwv_flow_tabular_form.set_row_values doesn't change values?

workspace: homeworldusername: test_reportpassword: test_report APEX version is 4.2.3, database 11g release 2... Application #: 202 : IR REPORTS TEST Page in question is page #2   

I have the report setup and need to make the following change... I have 2 columns: Comm and bonus,

if the bonus > comm, I need to change the text color of the bonus color to Red   if the bonus < comm

I need to change the text color of the bonus color to Green   if the bonus = comm, I need to change the text color of the bonus color to Black I have tried using code with the select and am NOT wanting that since it will be bundled with the data when downloaded as CSV or Excel.. Had thought about using the built in highlighting but that doesn't allow comparing a column to another.. Was thinking of a dynamic action, but not clear as to HOW to do it.

SQL & PL/SQL :: ORDER BY In A Particular Order

Jul 17, 2012

oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - 64bit Production
PL/SQL Release 11.1.0.6.0 - Production
"CORE 11.1.0.6.0 Production"

I have data like:-

event_idiss_nbr
171350 2012051WR
171350 2012041WR
171350 2011081CC
171350 2012041WA
171350 2012031WW
171350 2011081WW
171350 2011081CR
171350 2011081CA

The possible last two characters of the iss_nbr can be:-

WW, WR,WA,CR,CA,CC

And I want it to be ORDER BY as follows.

WR
WA
CR
CA
WW
CC

So for example, in above case, it should be

event_idiss_nbr
171350 2012051WR
171350 2012041WR
171350 2012041WA
171350 2012031WW
171350 2011081CR
171350 2011081CA
171350 2011081WW
171350 2011081CC

How can I do it while loading the table?

SQL & PL/SQL :: Order By Row ID

Mar 20, 2012

I am having table without any primary key. In this table, only inserts and deletes are performed , no update operation.

Is it safe to use order by rowid on such a table ? Does by applying order rowid, is it possible to check order in which rows were inserted in this table ?
