Different value for the element on the page on different areas on the same page?
Hi all:I use APEX 4.0.6 and I have a page with 4 regions and each of the region shows a classic report which SQL is very similar to the other:
for example
For region 1, the SQL looks like select * from history where status = 'A ';
For region 2, the SQL looks like select * from history where status = 'B ';.
For region 3, the SQL looks like select * from history where status = 'C ';
For region 4, SQL looks like select * from history where status = ';
To optimize database performance, I like to create a page element called p_status_value on this page and using the syntax of following link for the SQL statement for all 4 regions:
Select * from history where status =: p_status_value;
However, I need this page element value is dynamically change for each region:
For region 1, p_status_value = "A";
For region 2, p_status_value = 'B ';.
For region 3, p_status_value = 'C ';
For region 4, p_status_value = ';
Also, I need hide this element of the page on this page.
Can someone show me how to do this?
Thanks in advance!

Then I would have 4 regions, with each region report, create a box item in each area, called PXX_REGION_VALUE and then your request is:
select * from history where status = :PXX_status_value_X; (XX for page # and X for region #).. The database engine will crunch through the query and your dashboard will work fine..
Thank you,

Multiple values for the same column in the columns of diffétent in the same row?
Hi all
I wonder how you can display different values for the same column in different columns on the same line. For example, using a CASE statement, I can:
CASE WHEN CODE IN ('1 ', ' 3') THEN COUNT (ID) AS 'Y '.
CASE WHEN CODE NOT IN ('1 ', am') THEN COUNT (ID) AS "N".
Yes, that will produce two columns but will produce null values to empty and also two separate registers.
Any ideas?
Thank youAre you sure that this code works for you?
Select ID ,CASE WHEN MODE_CODE IN ('1', '3') THEN COUNT( No) END as "Fulltime" ,CASE WHEN MODE_CODE NOT IN ('1', '3') THEN COUNT( No ) END as "Other" From table group by ID
I guess the code above fails because MODE_CODE is not in your group by?
My suggestion would be to put the CASE in the COUNT:
Select ID ,COUNT(CASE WHEN MODE_CODE IN ('1', '3') THEN No END) as "Fulltime" ,COUNT(CASE WHEN MODE_CODE NOT IN ('1', '3') THEN No END) as "Other" From table group by ID
CASE expressions return no. when the respective conditions are true and NULL otherwise.
COUNTY will have non-null values. -

It is possible that a subject is more than once 'resolved' in the table BUSINESS_LOG
I want to count only one line solved for a topic.
I need to use only under RESERVE the table in the main query due to other counts.
Thank you very much.

in the examples before we talked abount 'Resolved' instead of 'resolved' as in your last example... to let you know, how it is stored.
I had advice is not to use SEPARATE.
So what... the evidence that any other question is faster than anything goes business_log, filter lines and can count distinct keys...
separate within a group function is not the same thing as do select distinct...

How can you specify the default value for the undefined array elements
According to aid LV, the tables have two default values, the normal default value and the default value for the undefined array elements.
I assume that there must be a way to specify the default value for later, but I can't find it anywhere. Any ideas?
I know that you can drag the item out of the table container. Change the default value on this scalar element. Then drag the item in table tank.

Is there a default value for the color management in PSE10? Beautiful photos from iPhoto, but blur with elements. I need help with this before as I consider that the upgrade to PSE13 and beyond.
Printing which forms an angle seems ok, but one that is horizontally seems faded, incomplete.
I was wondering if I saved a layer somewhere and set it as a default value.
If you group the layers, you will be left with a single layer, thus spreading your concern.
Suggest that you do the following:
- Make sure you have the latest drivers for your printers
- Reset the default preferences.
Hold the Alt, Ctrl + Shift keys when you click the icon to open the items. When asked if you want to delete the settings file, say Yes.
Items nearby and let regenerate the file.

Default value for the select list of type of form elements
Hello
I do not work with Apex that mutch, so this may be a simple question... but I still need help.
I have a form, in this form, I have a question P19_ONTVANGER_ID, this is based on a LOV.
This LOV is on a table that has a field of username with the value of APP_USER.
The table looks like:
ONTVANGER_ID this is the PK and is going to be the return value from the LOV.
NAME is the display value for the LOV.
USERID is the column APP_USER.
What users would like to get is that if they create a new record, the default value for the P19_ONTVANGER_ID field is their own ONTVANGER_ID.
But they must also be able to select another user.
hope there is someone out there that can and will help me.
Kind regards

Until now, I had, but I need to select the value of the id of the table and the list of selection item appears the corresponding value.How can I do this?
You can select the Type of default value as the body of the PL/SQL function
and to add something like that
declare v_return number; begin select your_id into v_return from your_table where some_column = :APP_USER; return v_return; exception when no_data_found then return null; end;

Best way to set the default values for the form elements
Hello
I have a form with a lot of defaults that is mentioned below...
I am currently using calculation-> after presents... then when we create/update a record... these computaion takes place and the default value for the inserted values get... THIS WORKS PERFECTLY WELL.Field value created by :APPL_USER creation_date SYSDATE last_updated_by :APPL_USER last_update_date SYSDATE item1 value1 item2 value2
I want to know... If this approach is fine OR we can have a better approach to achieve...?
Thank you
DeepakHello
I think it's good if it fits your need.
But why you have these fields in the form?
created by: APPL_USER
CREATION_DATE SYSDATE
last_updated_by: APPL_USER
last_update_date SYSDATEThe user can enter the ones?
I thought that those who are to audit and I would fill those drop with trigger in the database.
So that you get the same "correct" values if you need to manipulate the data with example of sql clientBR, Jari

How to add the default value for the "Full - Text Search" box
Hi all
I am looking for the ability to add a default value for the "Full text search" box in the search form.
Example:
When the user accesses the search page it get default values for some fields (defined in the rule as default values) such as
xField1 = txt1 and xFiel2 = txt2.
and Furthermore we need full-text = Hello world.
Is this possible?
Another way that we use is to open the search by URL with coreContentOnly = 1 as a form:
http:// < Server >/cs/idcplg? IdcService = GET_DOC_PAGE & to Action = GetTemplatePage & to Page = STANDARD_QUERY_PAGE & coreContentOnly = 1 & to xField1 = txt1 & to xFiel2 = txt2
It is possible to add full-text criteria here? Somethig like: & text = Hello World
Thank you
Leon
It is not possible in a very obvious way, not to mention that it is a rather strange request. I can't really imagine a realistic use for this case.
Anyway, without a messy customization, you should provide a default query with an FTX inside element text setting (i.e. "IdcService = GET_DOC_PAGE & Action = GetTemplatePage & Page = STANDARD_QUERY_PAGE & QueryText =
Hello World " "")To do this in a profile in the secondary effects of the profile section, add the following:
<$dpPromote("QueryText",>$dpPromote("QueryText",>
Hello everyone ") $>. -

Hello.
I have a document with some parties updated with the fusion of data (via placeholders). Is it possible to set a style of different cases for the same placeholder in the same text. See the example:
Mike runs its < < vehicule_placeholder > > in the city. But its < < VEHICULE_PLACEHOLDER > > is meant to be shared.
If the value of this placeholder in the file merger is 'bike', the sentence should be:
Mike runs his bike in the city. But his BIKE is meant to be shared.
Is this possible? How?
Thank you.
You can do it. A character style for this configuration placeholder text, set in all caps.

different values on the same grouping column
Hi all
I have a requirement to find different recordings of the same grouping columns have value different values in the columns, for example:
WITH
Data (G1, COL)
AS
(
SELECT 'A', '456' FROM dual UNION ALL
SELECT 'A', '345' FROM dual UNION ALL
SELECT 'A', ' ' FROM dual UNION ALL
SELECT ' 'B, 123' FROM dual UNION ALL.
SELECT ' 'B, 123' FROM dual UNION ALL.
SELECT ' 'B, 123' FROM dual UNION ALL.
SELECT 'C', "789' FROM dual UNION ALL
SELECT 'C', "789' FROM dual UNION ALL
SELECT 'C', "" the DOUBLE
)
Select g1, pass data
Ideally for G1 = A, the NECK should have that a single value across records ' 456 'or ' 345'. So I need to check the values in NOT NULL of the COL where, for any value of G1, we have different values of the colonel G1 = 'B' is perfectly fine, so I don't need. G1 = C is good too and I'm not worried about it. I only need these entries when the neck was non-empty value / NULL not different for the same value of G1.
So expected out put is
WITH
Data (G1, COL)
AS
(
SELECT 'A', '456' FROM dual UNION ALL
SELECT 'A', '345' FROM dual UNION ALL
SELECT 'A', "double UNION ALL
SELECT ' 'B, 123' FROM dual UNION ALL.
SELECT ' 'B, 123' FROM dual UNION ALL.
SELECT ' 'B, 123' FROM dual UNION ALL.
SELECT 'C', "789' FROM dual UNION ALL
SELECT 'C', "789' FROM dual UNION ALL
SELECT 'C', "the DOUBLE
)
Select g1,

Select g1,

Essbase Warning (1023135) skip certain values for the replication

My score has 2 spaces for these 3 members. Mapping advanced between the names of source and target members has been set in a field, but it was missing in the other (not detected by the validation of the partition!). I don't set it too and now no more warnings.Philippe Cuisset

Syntax to set a default value for the metadata of Web site field

DEU-00014: invalid value for the setting, "include".
Hi, I need to do an export of paintings from a schema and a particular query executed will apply to all the specified tables in "INCLUDE = TABLE: '('TBL1', 'TBL2') IN' in the command expdp.»
Now, I get the question in this setting INCLUDE. I have about 200 paintings to be included and I add this parameter INCLUDE in a separate parameter with all table names 200 file in Informatics and with the help of this parameter file in the expdp command.
Error message I get:
DEU-00014: invalid value for the setting, "include".
When I use the same process for 2 tables, this works very well. I think that there is a limit to the number of characters that can be used in the INCLUDE parameter. If so, then how do I use expdp to select only those 200 tables of 500 paintings in my diagram. I'd appreciate any help on this. Thank you.Hello
I'm sure that the limit is 4000 characters, but there are fairly simple workaround.
Create the table my_tabs (a varchar2 (30));
insert into my_tabs values ('your_table_name');
Repeat this step for each of your 200 tablesinclude = TABLE: "in ((SELECT from MY_TABS)) '"
You may need to mess you with the quote, but the value you were using is just an expression. It is only by using a different expression.
