operation of LogMiner column.

Hello

Please I analysis of the results of logminer and I found the column named 'operation', I understand the operation of INSERT, DELETE, UPDATE, COMMIT but what INTERNAL and medium not supported?

Thank you

Hello

Unsupported within the meaning of the statement that is executed or change has been caused by the operations performed by the user are not currently supported by LogMiner utility (for example, changes made to the tables with columns of the ADT). It may not able to describe it.

INTERNAL sense, the operation which is internall managed by ORACLE, for example consider the Chanied lines, when you insert a line / documents impossible to insert all of the data is too large.

Inside the ORACLE, will be chan lines, now it's an internal operation performed so that the OPERATION column INTERNAL for you and same rank migraiton.

I hope that you understood.

APEX_UTIL. IR_FILTER with BETWEEN operator for date columns
Hello

When I run my application, I can put a filter BETWEEN date columns. I can't find a way to use it with the APEX_UTIL. Function IR_FILTER. Maybe I missed something?

Tobias,

If you think about it, "between the" is nothing else than a way of the single line to say

WHERE: X > =: Y
AND: X<=>

Then you should be able to apply two filters of the report using the operators LTE and GTE

Hope this helps

Salvation in him between operator using date columns
Hello

I have a small doubut, once I try to get the results perticular between dates, it does not work
ex:-in the emp table I try to get employees rental u between January 1, 80, to January 3, 80
Once I use the query select * from emp where hiredate between January 1, 80 'and January 3, 80'
It is the display of different data.

Please help I want 01 alone, 2nd and data jan 3rd only how to write the query.

Thank you to
Hello

You can make the Portuguese the default language for the DATEs in your session saying:
```
ALTER SESSION  SET NLS_DATE_LANGUAGE = PORTUGUESE;
```
Note There are no quotation marks.

In a specific call to TO_DATE, you give NLS parameters in the 3rd argument:
```
TO_DATE ( '01-FEV-2009'
        , 'DD-MON-YYYY'
        , 'NLS_DATE_LANGUAGE = PORTUGUESE'
        )
```
This setting overrides the current NLS settiings session without changing them.

LogMiner SQL_REDO column ddl

Hello

We want to use logminer to get all activity on a subset of the tables in an ODS, historize the relevant tables in a central DWH.
For this we will use the SQL_REDO column.

For this that we are looking for a record structure that allows us to reinterpret the SQL_REDO varchar2 column (4000) into something that contains the relevant actual values as separate fields.
that is, the target table and the column; real movement (I/U/D).

Does something like this exist?

I know it's basically the SQL but then... It is not totally...

any suggestions welcome

Thank you very much

How to do a bitwise operation on a specific column in the database timesten

Hello
I need to do a bitwise operation and (&) operation on a column of data (whose datatype is NUMBER).
If I do something like SELECT 1010 & COLUMN1 from TABLENAME;
It will give the error: 'type 'NUMBER' not valid for operator 'BITAND' operand in expr data '.
Anyboday can help me?
Thanks in advance
Concerning
Arnaud

NUMBER is floating point format. Bitwise operators apply only to INTEGER values. There are several ways to work around it...

1. If the column in the database only stores integral values and then change its definition to NUMBER (n) (choose n) properly.

2. change the select statement to SELECT 1010 & CAST (COLUMN1 AS TT_INTEGER) (or TT_BIGINT according to the maximum value if you tore in the column)

3. change the column to a native integer TimesTen type as TT_INTEGER, TT_BIGINT etc. It uses less space and more efficient.

The columns should * only * be defined as NUMBER (with no precision or scale) if they really need to have this flexibility. Always use an explicit precision (and which adapted as appropriate) because this saves memory and allows to avoid this kind of issue. Better yet, use whole native types TimesTen, wherever possible. They use less memory and provide superior performance to those of all variants of NUMBER.

V13 Firefox is not consistent with the WC3 CSS columns

I use to be able to see multiple columns in v12 but is no longer in v13. Chrome and Opera display several columns but not FF v13.

Hello, the Date of issue for firefox 13 only could say that the support for the fill column property has been added - you give a link to a page where the problems occur?

Edit: apparently there is a problem with the height of a block of several column property. that will be solved by a release of the correction of a bug in firefox 13, which will be deployed in the coming days.

Column formula requirement

I'm new to OBIEE and I need to perform the following operations in the column change the formula:
CASE of SUBSTRING ('file'. "Column1" OF 1 TO 2)
WHEN 12 THEN VALUEOF (SUBSTRING ('file'. "Column1" FROM 1 to 6)) "
ANOTHER 'folder '. "' Column1 ' END
This obviously isn't a valid syntax for the CASE WHEN statement. But please advice as to how this functionality can be achieved.
Thank you
Srini.

You were close! Here it is a valid syntax:

CASE WHEN SUBSTRING ('file'. "Column1" FROM 1 FOR 2) = "12"

THEN SUBSTRING ('file'. "Column1" FROM 1 to 6)

ANOTHER 'folder '. "' Column1 ' END

Thank you

How can i two lists drop-down for the same column in OBIEE Dashboardprompt?
Hello

I need a report for a specific date range. I have to add 2 drop-down lists in the dashboardprompt for the same startdate and enddate column and the report must be filtered accordingly.

I can't add two drop-down lists in the DATE column in the same dashboardprompt.

How can I achieve this?

Can anyone help?
Hello

You should be able to achieve the desired result by setting the operator for the column ' is between ' when you set the prompt.

Kind regards

Filter for the bearing column week on number of possibilities
Hi all - I am trying to create a report that shows the number of projects for the past weeks 13 with a column for each week.

I can get the correct filter for the current week, but I don't know how to revise my expression sql for the previous weeks.

I use the 'In between' operator on the column of date with the following sql expressions:

TIMESTAMPADD (SQL_TSI_DAY,-(DAYOFWEEK (CURRENT_DATE)-1), CURRENT_DATE)
and
TIMESTAMPADD (SQL_TSI_DAY, 7-DAYOFWEEK (CURRENT_DATE), CURRENT_DATE)

As I said, this works to get the data for the current week. Does anyone know how I would revise to search beforehand for the week or two weeks earlier?

Thanks for any help!
Lacey
Hello!

If I understand correctly, you want to get a report showing the number of project per week for the current week and 12 weeks before? But according to what date? The date of project creation (I guess you have a field like that)?

In this case, you will need to place a filter by saying something like:

Where "Date of creation" between "Current date" and "Date of the day - 12 weeks.
* Date Opened. Date BETWEEN TIMESTAMPADD (SQL_TSI_WEEK-12, CURRENT_DATE) AND CURRENT_DATE *.

I guess you'll have to use the TIMESTAMPADD function with interval SQL_TSI_WEEK, the current date and the value 12.

I tested the service request creation date to have the number of service request for the last 5 weeks, it worked...

I hope this will help, do not hesitate to ask for more!

As you can see only the simple datatypes, nothing exotic.
But when you try
```
drop table test_lunkov CASCADE CONSTRAINTS purge;
```
I got error
30739 00000 - "cannot remove a table that has sub-tables.
* Cause: The user tried to drop a table that has defined sub-tables
under him.
* Action: Drop all sous-tables them before attempting this operation.
On
```
select * from test_lunkov
```
I had

* Cause: An attempt was made to access a table with columns in partially
abandoned the State (that is, drop the column was interrupted).
* Action: Propose to ALTER TABLE DROP the MORE COLUMNS to fill the drop
operation of the column before accessing the table.

On
```
alter table test_lunkov drop columns continue;
```
I had
table modified TEST_LUNKOV
and nothing has changed - neither FALL nor SELECT still does not.

TKPROF attached

Problem solved.

DO NOT TRY! ONLY FOR INFORMATION PURPOSES.
```
shutdown immediate
startup restrict
update tab$ set flags=... where obj#=...;
-- must be exactly 1 row updated, if not then rollback
commit;
shutdown abort
startup
drop table MDM_MASTER.TEST_LUNKOV;
```
This is table containing mat.view dropped.

How to have a CLOB in a form such as a hidden element?

Hello
I have a table which has a CLOB column and a corresponding form on the table.
As long as I put the question of the form which corresponds to the CLOB as TextArea or Rich Text Editor there are no problem with the CLOB.
But I don't want that item to be displayed, so I tried to do a hidden element.
This while making always fails with the following error:
Error during rendering of the element on the page P61_CFIELD001.
ORA-06502: PL/SQL: digital or value error: character string buffer too small
I guess that's because the length of the CLOB is larger that a VARCHAR2 can hold.
Y at - it an idea how can I achieve this?
APEX Version: 4.2.4.00.08
Oracle database: 12.1.0.1.0
TIA,
Dionisis

Should be OK. The process of the ARF/ARP will be operated on the columns in the table specified in the properties of the source element.

EL! vacuum gives "unexpected (unary) use" error
I'm under JDeveloper 11.1.2.3.0 to develop a Mobile application of the ADF.

I want to put the rendered property of an element to output text to #{! empty pageFlowScope.MyBean.myString}. However, it gives me the error:

The exception: ELException: EL Parsing Error: unexpected operation (unary) found-[column 8] #{! empty pageFlowScope.MyBean.myString}

How can I set the property made a component so that it is rendered only if the referenced string is not null and not empty?

Thank you very much.
NULL control does not seem to work, but looking for an empty as string above don't.

Thanks for your help.
