Using a function in a view

I have to include a function in a view. I want to create a new column in a view which is the output of this function. Can I do it. I am new to using functions..any sample code is appreciated..

INDEX on VIEW or TABLE when using CONTAINS function on the VIEW

Hi,
I'm querying a view with a contains function and I'm getting an error:
query: select * from view where contains(name,'jack OR jill')>0
ORA-20000: Oracle text error
DRG-10599 column is not indexed.
From what I gathered you can't create an index on the view, or is that possible afterall (using 10g).
Would it be sufficent to create an index on the column in the table that the view-query is pulling the data from? or can you use the contains funtion on views at all?
Or are there other ways of doing this better?
Thanks,

That particular CONTAINS clause will require a domain index on the column, NAME in your case.
You could also do: select * from view where name in ('Jack', 'Jill')
Depending on your need and number of records and other variables, it may be "fastest" to do the text index on the NAME column. If it is a rather small subset of data and performance is not critical then the IN clause should suffice.

Using analytic function in a view

Hello to all
Sorry If I use this thread
sql not merge using analytic functions
for my question,
From example you write and from Tom explain is not possible create a view on analytic function?
Thanks and sorry again

I think what you'll discover is that if you apply the function over the result set, the initial SQL might be quicker,
for example, this is a test I did with a large dictionary view:
select tp.Table_Name
      ,tp.Partition_Name
from
      select tbl.Table_Name         as Table_Name
            ,tbl.Partition_Date     as dt
            ,row_number() over (partition by dtp.table_Name order by dtp.Partition_Name desc) rn
      from (
            select /*+ all_rows */
                    dtp.Table_Name
                   ,dtp.Partition_name
            from    dba_tab_partitions dtp
            where   dtp.Partition_Name like 'Y____\_Q_\_M__\_D__' escape '\'
            and     dtp.Table_Owner     = 'APPS'
            and     dtp.Table_name      not like '%$%'
            and     dtp.Table_Name      like '%'
           ) tbl
    ) tp
where tp.rn = 1
select Table_Name
      ,Partition_Name
from (
      select /*+ all_rows */
              dtp.Table_Name
             ,row_number() over (partition by tbl.table_Name order by tbl.Partition_Name desc) rn
      from    dba_tab_partitions dtp
      where   dtp.Partition_Name like 'Y____\_Q_\_M__\_D__' escape '\'
      and     dtp.Table_Owner     = 'APPS'
      and     dtp.Table_name      not like '%$%'
      and     dtp.Table_Name      '%'
     ) tbl
where rn = 1I found the former to be quicker.
I think ask tom was saying a lot more, but included something similar,

Use Aggregate Functions in a View

Is it possible to create a view in SE11 using an aggregate SQL function?
I.e., I want the generated SQL to look like:
CREATE VIEW z_tbl
A,
SUM_AMT
AS SELECT
A,
SUM(AMT)
FROM TBL
GROUP BY A
Thanks for any help.

Executes the Native SQLstatements enclosed between EXEC SQL and ENDEXEC statements. Unlike Open SQLNative SQL statements can address tables that are not declared in theABAP Dictionary.
Example
Creating the Table AVERI_CLNT:
EXEC SQL.
CREATE TABLE AVERI_CLNT (
         CLIENT   CHAR(3) NOT NULL,
         ARG1     CHAR(3) NOT NULL,
         ARG2     CHAR(3) NOT NULL,
         FUNCTION CHAR(10) NOT NULL,
         PRIMARY KEY (CLIENT, ARG1, ARG2)
ENDEXEC.

Can anyone tell how to use daysbetween() function in analytical view?

I have been trying to create a calculated column in analytical view. Column needs to calculate days between two dates.
Using daysbetween (date1,date2) function, I have been trying to bring the difference but while validating i m getting error as date 1 is not an attribute.
Infact, I am using fields from my column itself but still not able to move further. Please help
Regards,
Vikram Sharma

Hi Peter,
The datatype is date, initially it was NVARCHAR type but i wanna keep it to date type so i changed it.
However, the query that you have given will calculate days from current date, right?. I have one date as a column in a table and another date is from input parameter.
So I need to calculate days lapse between two specified dates in which i have been unsuccessfull so far..
Also, just for your info. when i used this date function in HANA SPS 07 it was working fine but don't know what happen now when I am using it in SPS08.

Vikram

Using "Comlplete" function in Basic View

We have a Task List with 15 Data Forms that need to be cycled through as part of our budget process. We have an end user responsible for 5 departments. If the end user goes to the Data Form 1 for department 1 and enters their data, they then mark it as Complete using the box at the bottom of the Data Form. When they go to department 2 (using the drop down on Data Form 1) it is also marked as Complete. Is that normal? Or do we need to change a setting? What I am looking for is the abilty to use the Complete on just Data Form 1 with department 1. When I go to Data Form 1 for department 2 I am looking to see it as Incomplete. Is that possible?
Thx in advance.
Edited by: user8374782 on Aug 22, 2012 2:15 PM

Hi,
It is working as expected.
The "*mark complete*" helps user to identity the completed task, which means feeding data in all the departments in your case.
User will mark the data feeding task as complete, only when he/she is done with all data feeding in a particular web form and he/she is set to move to next task.
What I am looking for is the abilty to use the Complete on just Data Form 1 with department 1. When I go to Data Form 1 for department 2 I am looking to see it as Incomplete. Is that possible?I think the above requirement of yours might not possible.

Can not use TOUCH function on Nokia 6600 slide

Can not use TOUCH function on Nokia 6600 slide-
turned on sensor in phone settings, but when i touch the PHONE it does not work.
Please, tell me how use this function or maybe my phone is out of order

As long as your Sensor Settings are On within Menu, Settings, Phone, Sensor Settings then you just need to do the following -
Tapping
The tap function allows you to quickly
mute and reject calls and alarm tones, and
to display a clock just by double-tapping
the back or front of the phone when the
slide is closed.
Select Menu > Settings > Phone >
Sensor settings to activate the tap
function and vibration feedback.
Mute calls or alarms
Double-tap the phone.
Reject a call or snooze an alarm after
muting it
Double-tap the phone again.
Display the clock
Double-tap the phone.
(If you have missed calls or received new
messages, you must view them before you
can see the clock.)
Simply, if you double tap the screen when the slide is closed and you can see the clock appear then it is working.
I hope this makes it clearer for you.

Sending mails to UWL using SO_NEW_DOCUMENT_ATT_SEND_API1 function module

Hi all,
is it possible to view mails send using SO_NEW_DOCUMENT_ATT_SEND_API1 function module to UWL?
I am receving emails in my SAP Inbox.
Please guide.
thanks.

Hi,
You can only get the SAP mails into UWL notification tab with the Sonic connector (well of course with some custom development everything is possible).
One trick to get the workflow for sending "mails" to UWL is to NOT use email sending step, but instead use a decision step in the workflow and send this work item to the user. The decision step can include the same message as the email, and have onl one option "Confirm" (or whatever). These you can easily display in UWL since they are normal work items.

Karri

but i don't know VIEW_MAINTENANCE which of parameter meaning.
and how to control it.
who can give demo show.

thank you very much.

Please check doucmentation maintained for FM - VIEW_MAINTENANCE.
CUA functions to be deactivated dynamically
At runtime, the table EXCL_CUA_FUNCT must contain all those functions which are not to be callable in data processing , i.e. which are to be dynamically deactivated in the CUA interface at runtime. This is useful, e.g. for the following functions whose handling in cluster maintenance is ambiguous:
- 'ANZG' --> switch from 'Change' to 'Display' mode,
makes no sense in a maintenance cluster
- 'AEND' --> switch from 'Display' to 'Change' mode
makes no sense in a display cluster
- 'xxxx' --> other functions at the callers discretion.
The table must have the structure VIMEXCLFUN, as follows:
FUNCTION(4) TYPE C, ---> contains the function codes to be deactivated dynamically
MESSAGE(3) TYPE C. ---> online help auxiliary field (not yet supported)
Return ->
CUA functions to be deactivated dynamically
Database Access Selection Conditions The table DBA_SELLIST contains the database access selection conditions. The following fields must be filled:
Field name Contents
NEGATION NOT, if the condition is to be negated
SPACE otherwise
VIEWFIELD name of the field to which the condition is to apply
OPERATOR logical operator of the condition (e.g. 'EQ', 'NE',...)
VALUE comparison value of the condition in external format
AND_OR AND, if the next line of the condition is to be linked
to the current line by logical AND
OR , if the next line of the condition is to be linked
to the current line by logical OR
SPACE, if no further line follows
DDIC S, if the view field in DD is flagged as a subset field
(PM = 'S')
SPACE otherwise
TABIX Index of the view field in the view nametab
Notes:
1. Valid operators are: (see also ABAP doc.)
EQ - equals
NE - not equal to
GT - greater than
GE - greater than or equal to
LT - less than
LE - less than or equal to
CA - only for strings: contains at least one character of the comparison string
CN - only for strings: negation of CA
CO - only for strings: contains only characters from the comparison string
NA - only for strings: negation of CO
CP - only for strings: contains the pattern in the comparison string
NP - only for strings: negation of CP
CS - only for strings: contains the string in the comparison string
NS - only for strings: negation of CS
LK - like the LIKE operator in a SELECT ... WHERE clause
2. The function module does not (yet) check whether the selection conditions passed here are compatible with any conditions in the Data Dictionary view definition. The caller must ensure that this is the case.
Return ->
Database Access Selection Conditions

How to use a function PIPELINED in Forms 10g?

You can't. One option would be to wrap your pipelined function in a view, or you could write a stored procedure which returns a strong ref cursor instead.
cheers

Using a function return in an "IN" statement

All,
I need to filter the records in a table based on the return value of a function. The function determines a person's group and then executes 2 separate select statements depending on the group.
CREATE OR REPLACE PACKAGE pkg_rolebased
AS
CURSOR all_dmn_cur
IS
SELECT dmn_id
FROM tomwojeck.pa_domain ;
CURSOR child_dmn_cur (role_id_in IN varchar)
IS
SELECT distinct r.dmn_id
FROM tomwojeck.pa_domain_restriction_domain r
WHERE r.dmn_restriction_id IN (
SELECT DISTINCT a.dmn_restriction_id
FROM tomwojeck.pa_role_wf_entity_fct_access a
WHERE a.role_id = role_id_in
                    AND a.workflow_entity_fct_id= 'View Student.Student.View'
                    AND a.dmn_restriction_id IS NOT NULL);
FUNCTION rolelookup (stud_email IN varchar)
RETURN roletable;
END;CREATE OR REPLACE PACKAGE BODY pkg_rolebased
IS
FUNCTION rolelookup (stud_email IN varchar)
RETURN roletable
IS
v_roleid varchar2(200);
v_returnval varchar2(200);
v_data roletable := roletable ();
dmn_rec all_dmn_cur%ROWTYPE;
BEGIN
-- Find out the role of the person
SELECT r.role_id
INTO v_roleid
FROM tomwojeck.pa_user_prfl p, tomwojeck.pa_user_prfl_role r
WHERE p.user_name = r.user_name
AND UPPER (p.email_addr) = UPPER (stud_email);
IF UPPER (v_roleid) = 'ALL'
THEN
OPEN all_dmn_cur;
LOOP
FETCH all_dmn_cur
INTO dmn_rec;
v_data.EXTEND;
v_data (v_data.COUNT) := dmn_rec.dmn_id;
EXIT WHEN all_dmn_cur%NOTFOUND;
END LOOP;
CLOSE all_dmn_cur;
ELSE
OPEN child_dmn_cur (v_roleid);
LOOP
FETCH child_dmn_cur
INTO dmn_rec;
v_data.EXTEND;
v_data (v_data.COUNT) := dmn_rec.dmn_id;
EXIT WHEN child_dmn_cur%NOTFOUND;
END LOOP;
CLOSE child_dmn_cur;
END IF;
RETURN v_data;
END rolelookup;
END;
The select statement to filter on this mess is:
select
lname,
fname,
dmn_id,
stud_id
from tomwojeck.pa_student p
where p.DMN_ID in (select * from table(cast(tomwojeck.pkg_rolebased.rolelookup('[email protected]') as tomwojeck.RoleTable)))
The problemm is this performs horribly! If I enter an email address that causes the first cursor to be used, it runs well, but if I use an email address that causes the second cursor to run, it takes forever.
Is there a better way to do this?
Thanks,
Tom Wojeck

Using hsgetvalue function to retrieve Hyperion Planning Data

Hi All,
Lots of discussion about hsgetvalue, but still I do not succeed in using this function. Maybe someone can help.
Is this function work for HFM or also Hyperion Planning? Currently we are using Hyperion Planning 11.1.1.3 with related Essbase. This is what we've tried in Excel:
=hsgetvalue(“";”Scenario#BudFin;Year#FY12;Period#Begbalance;Partner#NA_Partner;Product#A251;Account#BOM Weight;Version#Working;Misc#R-SBDA;Entity#No Entity;Currency#Qty") ===> the result is syntax error.
=hsgetvalue("","Scenario#BudFin","Year#FY12","Period#Begbalance","Partner#NA_partner","Product#A251","Account#BOM Weight","Version#Working","Entity#No Entity","Currency#Qty","Misc#R-SBDA") ===> the result is No Connection.
Actually I'm still confused about the Connection parameter, which connection name we have to use?
Thanks.
Gajah

Hi,
HsGetValue
Data sources: Financial Management, Hyperion Enterprise, Essbase
HsGetValue retrieves data from the data source for selected members of a dimension. When HsGetValue retrieves no data, the value specified for the #NoData/Missing Label replacement option is used.
When users select Refresh or Refresh All, only HsGetValue is called. When users select Submit, HsSetValue is called first, HsGetValue is then called only if HsSetValue returns successfully.
Syntax
HsGetValue(“Connection”,”POV”)
Connection parameters can have these values:
Empty: the default connection
HsActive: the active associated connection
The user-defined name for a private connection
You connect to data sources through shared or private connections.
_# Shared Connections_
Shared connections are stored in a central location and are available to multiple users through the Smart View Panel. You cannot add, edit, or rename shared connections, but you can save them as private connections, which you can edit and rename.
_# Private Connections_
Private connections are those that you create by saving a shared connection to your local computer or by entering a URL to a provider that is not configured for shared connections. When you create a private connection, it becomes the active connection.
Creating Private Connections
You can create a private connection from a connection that is not listed in Shared Connections if you know the URL.
To add a connection using a URL:
1. From the Smart View ribbon, click Panel.
2. From the Smart View panel, click the arrow next to "Home" Icon, and then select Private Connections.
3. In the text box, enter the URL or the local storage directory for the data source to which you want to connect. The URL syntax for the various data sources is as follows.
Financial Management: http(s)://servername:port/hfmofficeprovider/hfmofficeprovider.aspx
Hyperion Enterprise: http://servername:port/heofficeprovider/heofficeprovider.aspx
Planning: http(s)://servername:port/HyperionPlanning/SmartView
Essbase: http(s)://servername:port/aps/SmartView
Reporting and Analysis: http(s)://servername:port/raframework/browse/listxml
Financial Close Management: http://servername:port/fcc/servlets/smartview/fcmsvservlet
Oracle Hyperion Strategic Finance: http://servername:port/StrategicPlanning/SmartView
4. Click Next Button
5. Enter the Name of the connect as "Essbase_Conn"
6. Enter username, password and connect the worksheet.
Now you can create functions by two methods -
1. Using Function Builder
2. Manually (Which you have opted)
To create a function manually:*
1. In Excel, click the cell in which you want to enter the function.
2. Enter = (equal sign).
3. Enter the function name, HsGetValue, for example.
4 Enter parameters for the function,
HsGetValue(“Connection”,”POV”)
Connection parameters can have these values:
# Empty: the default connection
# HsActive: the active associated connection
# The user-defined name for a private connection
so the function looks like this:
HsGetValue(“Essbase_Conn”;"Year#Jan;Measures#Sales;Product#100;Market#East;Scenario#Actual")
5. To refresh the worksheet, from the Smart View menu, select Refresh. Functions are validated only when you refresh them.

Using packaged functions in Apex

Hi,
I'm fairly new to apex and I am about to write an app which needs to access a SQL server database. My local dba has set up the transparent gateway and I can select from and update the SQLServer database no problem via a db link. What I need to decide is whether to code the sql for reports etc directly into the apex page or to call a pl/sql function returning a select statement. I would like to have all the code in packages as a lot of it will be used by multiple apps in future but is there any extra overhead in doing this:
declare
l_sql varchar2(4000);
begin
select package.function into l_sql from dual;
return l_sql;
end;
rather than coding the SQL directly in the page? Also is there a more efficient way of using packaged functions to select data rather that just have it returning sql statements.
Thanks in advance.
Dave

Hi
I only use function returning select when I have a strong reason to do so, because it is so much more difficult to test and maintain. Not sure about performance, but I think it is not that much worse.
If you simply want to reuse SELECT statements, you could use views instead.
Anyway, if you decide to use the package solution, at least you can make it much simpler -- just code like this in the page:
return package.function;
I hope this helps.
