30EA1: confusion in tab name holding PL/SQL code

If I edit a PL/SQL function and use it as a starting point to create a similar one, the buffer/tab keeps the original name even after successful compilation of the new function. After refreshing the list of functions in the left-hand tree, the new function appears, yet clicking on the original one simply re-activates the similarly named tab, which now holds the code for the new function. That's pretty confusing, really.

Fixed in EA3 (cannot remember if I checked EA2).
The tree even automatically refreshes as soon as you compile your new function, great!

[SOLVED] Reverting Guake terminal tab names back to 'Terminal #'

The new version of Guake (0.4.3) implemented 'Better Tab Titling'. This means that instead of a new tab name being 'Terminal #' (where # is an auto incrementing integer), it instead forced the title to be equal to the VTE prompt.
My issues were that there was no way to set a preference to switch back (as I prefer the simple tab name) and that tab names could/would take a very large amount of space (as it would put my whole username@server:/path/to/where/i/am/at).
So I figured out how to fix and thought I'd share in case anyone else would like to switch back:
NOTE: I believe python is spacing-sensitive (please correct me if I'm wrong). All the lines (added/edited) are indented 8 spaces.
edit /usr/bin/guake
find: self.selected_tab = None
after that line, add:
# holds the number of created tabs. This counter will not be
# reset to avoid problems of repeated tab names.
self.tab_counter = 0
find: def on_terminal_title_changed(self, vte, box):
after that line add:
return
find: Adding a new radio button to the tabbar
the next line will read:
label = box.terminal.get_window_title() or _("Terminal")
change to:
label = box.terminal.get_window_title() or _('Terminal %s') % self.tab_counter
find self.tabs.pack_start(bnt, expand=False, padding=1)
after that line add:
self.tab_counter += 1
After editing the file, restart Guake for the change to take effect.

I have been using Guake for years and I think the tab bar is in the way. I disabled it a very long time ago and didn't look back.
Here are the shortcuts that I use:
"~" to toggle it.
Ctrl+T for a new tab (just like in Firefox, Chromium).
F1 and F2 for next and previous tab.
F3 close tab.
Basically, I don't need more than two tabs at a time; three tops, in very rare cases.
Hope it helps.

Creating tabs for a single SQL report type region

I would like to find a way to use tabs in a single SQL report type region. The problem I have is that there are too many columns to be displayed so the report looks very cluttered. I would like to find a way to assign say columns 1 - 5 to tab 1, 6-10 to tab 2 etc so the user can find the columns they need by simply clicking on the various tabs without having to execute the query again.
I have looked at JQuery tabs but that seems to only be applicable to more or less unrelated regions. I tried to create different regions using the same query with different columns and that kind of works, but the regions don't stay in sync if say the user change the order for column 2 in tab 1, when they click on tab 2 everything displays in a different order.
Another wrinkle is that this is an updatable report so some of the columns are updatable.
I also looked at the hide / display column solution which is described in a few threads and that may also sort of work, but it is also not quite what I am looking for.
Any help is greatly appreciated

Does anybody know if this can be accomplished using APEX? What I am really looking for is very similar to an old fashioned client / server screen developed using say Oracle Forms. Consider an order line screen where say columns line number, SKU and SKU description is to the left of the tabs so these columns are visible no matter which tab is active. Then the first tab has say pricing information including UOM, quantity, list price, unit selling price, price list. The next tab has say customer information including customer number, name, bill to and ship to addresses. the next tab has say shipping information with say the warehouse, shipping instructions and shipping method.

Getting tab name or tab id or tab label at runtime

Hi All,
I think the answer is "no" but I'm going to ask anyway just in case I missed something.
I am designing some authorization schemes for my application. The context behind the design is this:
1. Two-level tabs application.
2. Access is stored in a table where an assignment between a level 2 tab is assigned to a user (well, it's really assigned to groups of users but that's not that important for this question). The level 2 tab is assigned via a select-list LOV defined as:
select
tab_label d,
tab_id r
from apex_application_tabs
where application_id = :APP_ID
and workspace = :OWNER
order by 1
So I store the TAB_ID of the 2nd level tab and it's assigned to groups of users.
So what I'd like is this at runtime:
1. For page-level security, I read the Apex data dictionary and pass APP_PAGE_ID to a function that reads the page number. I traverse the tab hierarchy in APEX_APPLICATION_TABS to see if the APP_PAGE_ID resides in TAB_PAGE or TAB_ALSO_CURRENT_FOR_PAGES to get the TAB_ID. Then I check my own assignment table to see if that TAB_ID is accessible to the user. If so, return TRUE, else, return FALSE. This is working wonderfully and isn't a problem...at runtime if I navigate to a page that is on a 2nd level tab and I don't have access to the page, the security scheme errors (correctly).
2. For tab-level security, I want that at the parent tab level that if the user has access to one or more of the 2nd level child tabs, display the parent tab.
3. For tab-level security, if the user is on a parent tab (because he/she has access to at least one child tab), only show the child tabs to which they have access.
Now the problem(s). The thing is that the user sees the tabs before they navigate to them (#2 and #3 I don't have working right now) and I want to hide them if they don't have access.
For example, let's say my parent tabs are A, B, and C. Child tabs are A1, A2, A3 underneath A. B1, B2, B3 underneath B. C1, C2, and C3 underneath C.
Let's say everything in A and underneath A (so A1, A2, and A3) are available to anyone who has a login to the application. No problem there.
Then, let's say most or all users have access to B1 but fewer users have access to B2 and B3. What I want is that if anything from B is available to a user, show parent tab B. If the user clicks on parent tab B, then show B1, B2, and B3 but only show the tabs to which they have access (so if they have access to B1 and B2 but not B3, do not display B3).
Then, let's say C is a very powerful administrative tab and very few people have access to it. I want to not-show C at all for people who do not have any access to C1, C2, or C3.
The problem I have at runtime is that I cannot find a way for a tab to pass information about itself when the tab is about to paint (or not-paint). The only variable or substitution string at runtime that I can find to reference about a tab is "CURRENT_PARENT_TAB_TEXT". However this gives me only information about the parent tab's text of the parent tab that has focus right now; each parent tab cannot pass it's own info until I navigate there. I need to get that information w/o navigating to the tab first so that I can determine to show/hide the tab. Does that make sense? In other words, at runtime, I log into the system and let's say I'm not very powerful and should only be on tabs A1, A2, and A3 under A. I log in, I land on A1, and I can see A2 and A3 (good), but also I can see parent tabs B and C poking up there too. CURRENT_PARENT_TAB_TEXT does not resolve to B or C (it currently resolves to A) until I actually try to click on B or C. I need to hide B or C before the user clicks.
Yes I can do it if I hard-code the name of the tab in a security boolean function, but I would have to have as many authorization schemes as I have tabs. This is why I want just one tab-level scheme where I pass the tab name or ID at runtime dynamically but I can't seem to reference it.
Over in the template for two-level tabls I see #TAB_LABEL#, #TAB_NAME#, #TAB_ID#, and #TAB_LINK#. These don't seem to be available to PL/SQL to pass at runtime to a PL/SQL function. If they could, this would be my answer.
Any other options or am I stuck on this one?
BTW...we are on version 3.2 of Apex and going to version 4 soon. If something is available in 4 for this that helps, I can do it then.
Ideas? Thanks!

Hey gti_matt,
Did you end up getting anywhere with this?
I'm in the same boat atm...
Thanks,

Tabs tab name or tab id

Hi
I'm writing application with access control to several tabs there will be condition checking if user :APP_USER have access to selected tab. The point is how to get tab_name or tab_id. and use it in pl\sql function like I can use :APP_USER
Or
how can I do this without using tab_id
Regards
Jaroslaw

CREATE OR REPLACE
FUNCTION can_user_access_tab(p_user IN VARCHAR2
                                                ,p_tab   IN VARCHAR2
RETURN VARCHAR2
IS
ln_count number;
BEGIN
SELECT count(1) INTO ln_count
FROM acces_tab_users
WHERE username=p_user
AND tab_name=p_tab;
if (ln_count=0) THEN
     return 'N';
else
    return 'Y';
END;to each tab add a SQL expression condition
can_user_access_tab(:APP_USER,'<tab name>') = 'Y'
Note : <tab name> would be different for each tab , so you have to modify the conidtion for each tab with a new string that matches your table's(acces_tab_users) tab_name column.
If you want to use an authorization scheme which uses tabname and user , there is a substitution string named CURRENT_PARENT_TAB_TEXT that might work for you. But I couldn't find anything for the sub tab.
In the authorization scheme that would be
return can_user_access_tab(:APP_USER,:CURRENT_PARENT_TAB_TEXT) --function returns BOOLEAN in this caseI haven't used it, so can't provide any more info on this at the moment.
Update
Use Jari's method and pass :APP_USER and :APP_PAGE_ID to the authorization scheme. You would have to set up the tab access table based on the page number for this.

Getting the tab name

Version: 4.1.1.00.23
Hey,
I need to capture the tab name when it is clicked. Is there any way to do this??
I created dynamic breadcrumbs and when the user clicks the tab to enter a page the application items used to contain the values for the breadcrumb path are not being cleared. So when the user clicks a tab to go into the page directly the breadcrumb path is the last entry created in the trail, but it should be the only entry in the breadcrumb path.
eg: User is on Page 1 and clicks a button bringing them to page 2 and the breadcrumb will be Page 1>Page 2.
However, if the user clicks a tab to go directly into page 2, the breadcrumb should just be Page 2 and it's showing Page 1 > Page 2 and this is because the application items holding the values are not being cleared.
Does someone have a solution to this?
Thanks.
Parth.

If it's a standard tab then the value of the built-in substitution string REQUEST is set to the tab name when it is clicked.
Alternatively, query the APEX_APPLICATION_TABS view using the page ID in a Before Header computation/process in the destination page, something like:
select
          aat.*
from
          apex_application_tabs aat
where
          aat.application_id = :app_id

                  ',' || aat.tab_also_current_for_pages || ','
                , ',' || :app_page_id || ',') > 0)

Getting Tab Name or Tab Id

Hello,
In my page I have 4 tabs. I would like to get the tab name or tab id to pass to my pl/sql procedure. When user clicks the tab, I am passing certain parameters to the plsql procedure. So is there any way i can uniquely get the tab name or tab id?
Thanks in advance
Regards

well,
it is still vague for me to understand what do you mean by getting tab name from URL.
perhaps what you intend to have is a programmatic way of finding tab name from URL.
for that in 10.1.4 as the query strings do not work that way, so you may use the following API function call and use it to write some custom function. (note that it will work when you will call it from some page on your portal).
portal30.wwctx_api.get_path_infothis gives typically a result like this depending upon the page address/location (and provided that you are on a tab of a multi-tab page):
/!PORTAL30.wwpob_page.show/SHARED/U/PAGE_GRP/PAGE_NAME/TABNAMEhope that helps!

LOV of sub-tab names

Hi
I'm trying to include a page to submit bugs in my app and I'd like to include LOVs for the tab and sub-tab names, since the users never see the page numbers. Anyone know how I can query for them in my LOV definitions?
Thx
Derek

As Anton said, the best thing is to store your custom headings in a table so that you can use the table for your LOV as well as for your report headings.
To use dynamic report headings, you can use the 'PL/SQL function body returning colon-delimited headings' feature on the Report Attributes page.
So, if your report headings are stored in table t that function body can be
declare
l_headings varchar2(4000)
begin
for rec in (select heading from t) loop
l_headings := l_headings||':'||rec.heading;
end loop;
return ltrim(l_heading,':');
end;Hope this helps.

How to dashboard tab name

Hi,
My dashboard has 10 tabs (pages). 5 of them are main tabs which are shown all the time. The rest of the tabs are sub-tabs and hidden so user don't get confused. When user navigate to a sub-tab via a link in main tab, I'd like to show the tab name up next to the dashboard name. Something like
myDashboard -> myTab
Is there a way to do this?
Thank you in advance for your ideas.

You will have to write a VBScript to achieve what you want.
Here is an example. This VBScript returns the name of the first tab:
     Set XLHandle = CreateObject("Excel.Application")
     XLHandle.DisplayAlerts = False
     Set XLBook = XLHandle.WorkBooks.Open("<path>\<file>.xls")
     Set XLSheet = XLBook.Sheets.Item(1)
     wscript.echo XLSheet.Name
     XLBook.Save
     XLBook.Close
     XLHandle.Quit
     Set XLSheet = Nothing
     Set XLBook = Nothing
     Set XLHandle = Nothing
Call the script tab.vbs from within your DS script and assign the result to a global variable.
     $TabName = exec( 'cmd','cscript //nologo C:\\Users\\Administrator\\Documents\\BI4B\\tab.vbs',0);

Rep-1401: formula name : Fatal Pl/SQL error occured

Hi,
I am using report builder 6.0 and recently came across a error while running the report. Rep-1401:<formula name> : Fatal Pl/SQL error occured.
I created a formula column in the report. In that i have three local variable.
f_val number := 0;
s_val number := 0;
t_val number := 0;
t_val := f_val/s_val ; --> this gives the above fatal error.
t_val := (f_val + 1)/s_val; --> this gives the above fatal error
t_val := f_val/(s_val + 1); ---> no error
if i change the value of s_val
s_val := 1;
t_val := f_val/(s_val - 1) ; ----> this gives the above fatal error.
Can anyone help me to solve this problem or is it report builder bug.
Please help me, as i desperately need help.
Thanks

Thanks for ur reply.
I used nvl too, but the same error occurred.
For the information in my question I by mistake typed
t_val := (f_val + 1)/s_val; --> this gives the above fatal error.
but when the value of f_val = zero and s_val is zero why it gives fatal error when i divide, i used nvl on both the variable while dividing but still got the same error.
but if s_val is greater than zero then no error occurs.
please help me, I feel it is a bug.

How to use a variable as a table name in PL/SQL?

Hello all.
I was given one day to wrote a piece of PL/SQL code to do a query. That is,
First select two columns from one table and use them to build another table's name, then
     join the two tables. I'm not sure if variables can be used in the select list, if possible,
     how to reference them?
-- My code is
DECLARE
     tablename varchar2(40);
     CURSOR c1 IS
select a.sourcesystemcode, a.adminorganizationno from cdb1.organization_mapping a
where exists( select 1 from cdb1.organization_mapping b where
a.cdborganizationno = b.cdborganizationno and a.adminorganizationno != b.adminorganizationno)
order by a.cdborganizationno,a.adminorganizationno;
     v_src_sys_cod cdb1.organization_mapping.sourcesystemcode%TYPE;
     v_adm_org_no cdb1.organization_mapping.adminorganizationno%TYPE;
BEGIN
OPEN c1;
LOOP
FETCH c1 INTO v_src_sys_cod, v_adm_org_no;
EXIT WHEN c1%NOTFOUND;
tablename := 'ODS1.SRC_' || v_src_sys_cod || v_adm_org_no || 'ACTORG_CURR';
select c.cdborganizationno, c.sourcesystemcode, c.adminorganizationno, c.sourceorganizationno, d.ibkcde, d.orgnam
from cdb1.organization_mapping c inner join tablename d on c.sourceorganizationno = d.orgidt;
END LOOP;
CLOSE c1;
END;
The error message says "... the table or view does not exist... line 18, column 66..."
It says the variable "tablename" wasn't build or build incorrectly.
Please give the solution.

If the TABLEs being queried are already known, and it is just a matter of which one to query, perhaps you can CREATE a VIEW that uses all the TABLEs with a UNION ALL, and include an identifier COLUMN.
CREATE VIEW SRC_ALL_ACTORG_CURR
AS
SELECT 'aa' Name, ibkcde, orgnam FROM SRC_aa_ACTORG_CURR UNION ALL
SELECT 'bb' Name, ibkcde, orgnam FROM SRC_bb_ACTORG_CURR UNION ALL
SELECT 'cc' Name, ibkcde, orgnam FROM SRC_cc_ACTORG_CURR UNION ALL
SELECT 'dd' Name, ibkcde, orgnam FROM SRC_dd_ACTORG_CURR UNION ALL
SELECT 'ee' Name, ibkcde, orgnam FROM SRC_ee_ACTORG_CURR;
Then, in you query:
select c.cdborganizationno, c.sourcesystemcode, c.adminorganizationno, c.sourceorganizationno, d.ibkcde, d.orgnam
from cdb1.organization_mapping c inner join SRC_ALL_ACTORG_CURR d on c.sourceorganizationno = d.orgidt and d.Name = v_src_sys_cod || v_adm_org_no;

How can I get the View Tab name on the Crystal Report Viewer at runtime?

When a report is displayed in the Windows Forms Crystal Report Viewer and the user drills into the report, the drill down view is displayed in a seperate view and is identified via a View tab at the top of the report. I can determine the index of the view tab that is currently selected, but I need to access the text that is on the View tab. The only properties that I've found that pertain to the "view" on the Crystal Report viewer are the ActiveViewIndex and the ViewCount. Unfortunately, neither of these items help me because they are not specific to a certain section of the report. Has anyone had any luck accessing the View Tab properties ? Thanks.

The tabs at the top of the page are nested within some of the viewers controls. Through trial and error you just have to find the right one. In this case the main part of the report is in the first control. This happens to be a TabControl. From there you can loop through the TabPages on the TabControl to grab the names of the tabs.
Here is a quick example of what I did to get the tab text. All this code was in a button click event.
Control oControl = crystalReportViewer1.Controls[0];
TabControl oTabControl = (TabControl)oControl.Controls[0];
foreach (TabPage oTabPage in oTabControl.TabPages)
MessageBox.Show(oTabPage.Text);

How to get current tab name or tab id or related info?

Hi ,
I would like to hide/show tabs according to users' page privileges list. So I need get current tab ID or tab Name in runtime environment to know if show/hide it for current user. :APP_USER
Could you please provide any info about this requirement? Or do you have alternative method to control tabs' hide/show?
thanks

Hi Jari,
Thanks for your info. Even if set authorize schema to tabs, I still need to get the relationship between "current tab" and "privilege&users". So I think evrm's hard-code method above is avaliable.I agree with Jari: APEX provides Authorization schemes specifically for this purpose. You need to reverse your thinking on how to implement this.
For more information consult the documentation on APEX security, specifically using authorization schemes to restrict access to pages and control rendering of components.
Tutorial: Adding Security to your Database Application (APEX 4.0)
Use Authorization Schemes to control access/rendering for security ("only managers see/access this page and it's associated tab"); and Conditions to control rendering for functional reasons ("region only displayed if account is in arrears").
Authorization Schemes have the benefits of being reusable, performing better, and allowing central maintenance of security-related code. This makes it easier to change the implementation—say moving from role information held in database tables to groups defined in LDAP.
I worked for a number of years with an application where authorization schemes are not properly used (decisions made before my involvement) and all security and business logic relating to rendering and processing is wrapped up in spaghetti code in conditions. It's impossible to maintain.
It is of course advisable to make both authorization scheme and business logic condition code more reusable and maintainable by locating it in API packages.

I need the "Real" Table / Table Column names from a sql view

Firstly, we have a system with ~1000 tables and ~250 views. We have field level security on the table columns (in our code)
Now we have a lot of views which select data from the tables, but I need to get the "Table Column Name" that is linked in the view.
I know there are view columns that is not linked to a specific table column, (or concatenation of columns) so those columns can just return NULL.
From the sample you will see there is a view selecting data from another view. I know it is not the best sql performance (execution path) but that is another topic on its own.
I went through a lot of the sys.* stored procs or sys.* views to try and figure out if there is a view that we can use to get the expected results.
here is the sql code:
if
Exists (select
* from
sys.all_objects
where name =
'AliasView2')
drop view dbo.AliasView2
if
Exists (select
* from
sys.all_objects
where name =
'AliasView1')
drop view dbo.AliasView1
if
Exists (select
* from
sys.all_objects
where name =
'Table4')
BEGIN
alter table dbo.Table4
DROP CONSTRAINT [FK_T4_T3]
alter table dbo.Table4
DROP CONSTRAINT [PK_T4_Constraint]
drop table dbo.Table4
END
if
Exists (select
* from
sys.all_objects
where name =
'Table3')
BEGIN
alter table dbo.Table3
DROP CONSTRAINT [FK_T3_T2]
alter table dbo.Table3
DROP CONSTRAINT [PK_T3_Constraint]
drop table dbo.Table3
END
if
Exists (select
* from
sys.all_objects
where name =
'Table2')
BEGIN
alter table dbo.Table2
DROP CONSTRAINT [FK_T2_T1]
alter table dbo.Table2
DROP CONSTRAINT [PK_T2_Constraint]
drop table dbo.Table2
END
if
Exists (select
* from
sys.all_objects
where name =
'Table1')
BEGIN
alter table dbo.Table1
DROP CONSTRAINT [PK_T1_Constraint]
drop table dbo.Table1
END

The desired results must be like the following:

dbo
AliasView2

varchar

dbo
AliasView2
T3_Field1
Table3
T3_Field2
varchar
1
dbo
AliasView2
T3_Field2
Table3
NOTE: the COLUMN_NAME and TABLE_NAME must the REAL field of the TABLE it belongs to and not only ONE LEVEL Higher’s ALIAS View Name

Now we have a lot of views which select data from the tables, but I need to get the "Table Column Name" that is linked in the view.
If you are using SQL Server 2012/2014, then you can use
sys.dm_exec_describe_first_result_set (Transact-SQL) to gte the informations.
