Select from Query ? / Dynamic view ? Anything else ?

Hello,
This could be a bit challenging. (or maybe not, i hope)
I have to create a report which is based on 3/4 tables with pretty complex SQL.
Step 1. I have to use views (in the database currently) to select data from these tables.
Step 2. Then create the next set of views (in the db) based on the previous views.
Step 3. Then finally join the last set of views in Reports and create the report based on the PARAMETERS entered.
This was fine, until the client changed the criteria. Now the views have to be created but the PARAMETERS affect the FIRST set of views.
That is, the views in the FIRST STEP will have a where condition based on the parameters at RUN TIME.
I was wondering about how to do this ?
1. Can I use dynamic views (in db) passing the where condition parameter to the where clause ? Alternatively use DDL in Reports.
OR
2. Create a query in Reports and create subsequent QUERIES BASED ON THE FIRST QUERY (like MS Access). Can this be done ?
3. Any other way ?
If you need any clarification, I can provide that.
THANKS for taking the time to read it. It would be great if you could give me any ideas.
Pat.

hello,
you might look into REF-CURSOR-QUERIES for this particular case. it might help.

We will make a sample from this request and post it on OTN. I have pasted all the JSP code so you should be able to use it directly. Just change the BISession details and the presentation references.

Selection from a Maintenance View

Hi,
I have to fetch data from a view, unfotunately that view is a mainteance view. Is there any other way to select/fetch data from that view in my report program ?
Regards,
Bharath Mohan B

Hi
U cannot access the data from maintanence view.
Only projection and database view can be used in ABAP code.
If u want to access the Data from more the one table , Create the DATABASE VIEW and use this view in ur program.
For example : UR Database view name is Ztest
in ur program
table Ztest.
select * from Ztest ***************

Creating and selecting from a dynamic table

Hi,
Iam trying to create a table dynamically and selecting from it in same plsql block, but am getting "table doesnot exist" error. however if i just create a table dynamically and then do a select on it seperately it works..
below is sample code for the same,
working
Line: -----
DECLARE
loc VARCHAR2(20):='bglr';
l_cnt pls_integer;
BEGIN
-- create an employee information table
EXECUTE IMMEDIATE
'CREATE TABLE ' || 'emp_bglr' ||
empno NUMBER(4) NOT NULL,
ename VARCHAR2(10),
job VARCHAR2(9),
sal NUMBER(7,2),
deptno NUMBER(2)
end;
select count(*) from emp_bglr ...works and return me 0 rows
Line: -----
but when i include select in plsql block ..it throws "Table does not exists" error...(iam running below plsql block after dropping the created table)
not working
Line: -----
DECLARE
loc VARCHAR2(20):='bglr';
l_cnt pls_integer;
BEGIN
-- create an employee information table
EXECUTE IMMEDIATE
'CREATE TABLE ' || 'emp_bglr' ||
empno NUMBER(4) NOT NULL,
ename VARCHAR2(10),

deptno NUMBER(2)
--COMMIT;
END;
Select count(*) into l_cnt from emp_bglr;
dbms_output.put_line('cnt is '||l_cnt);
end;
Line: -----

Becuase your code is first checked for syntax/object existance during compilation and throws an error saying the table does not exist.
Try this:

Newbie Select * FROM table where IF Numeric else something else

I have a text on a web page. If one can enter an EMPLOYID ( like 55 ) or
lastname like 'SMITH'.
I tried using INSTR and Substr but no avail.
Select *
from Atable
WHERE
IF SUBSTR(myfield,1,1)="0" OR
IF SUBSTR(myfield,1,1)="1" OR
etc.
EMPID=to_number(myfield)
ELSE
Upper(Lastname) like Upper(myfield)
Suggestions?
TIA
Steve

Yes myfield could be either "55" OR it could be "SMITH"
Otherwise I would have to have 2 textboxes on the web page.
One for EmployeeID and one for lastname.
Thanks.

Lock users selected from query.

I need to have the user IDs that are selected using the query I've pasted below locked. My thought was to put the query into an array and then use a loop to run through the array with the "alter user user_id account lock" command but I have no idea how to get that far is that even possible with plsql? Or perhaps there is a better way to do this. I would then be running this script once a week to make sure all of these users are locked.
select username from dba_users where username like '_Z%'
minus
select distinct schema from monadmin.log_info where timestamp>=sysdate-92
minus
select account_status from dba_users where account_status = 'locked';

select account_status from dba_users where account_status = 'locked';This will not return anything as the status is LOCKED not locked.
secondly you will get account_status not the username
BEGIN
    FOR rec IN (
                 select username from dba_users where username like '_Z%'
                minus
                 select distinct schema from monadmin.log_info where timestamp>=sysdate-92
                minus
                 select username from dba_users where account_status like ( '%LOCKED')
               ) LOOP
      EXECUTE IMMEDIATE 'ALTER "' || rec.username || '" ACCOUNT LOCK';
    END LOOP;
END;

Can not select from data dictionary view from a procedure

Hi,
I wonder, which privilege is missing here:
my schema has this roles and privs:
GRANT CONNECT, RESOURCE TO cb ;
GRANT CREATE SESSION TO cb ;
GRANT SELECT_CATALOG_ROLE TO cb ;
GRANT CREATE SYNONYM TO CB;
GRANT CREATE VIEW TO CB;
I create a procedure:
create or replace procedure dd_test as
begin
     dbms_output.enable(2000000);
     for r in (select table_name from sys.dba_tab_partitions     where owner = 'CB') loop
               dbms_output.put_line(r.table_name);
     end loop;
end;
sho err
4/38 PL/SQL: ORA-00942: table or view does not exist
When I run the core statement form sql prompt, it works !
so what privilege is missing here ???
thanks for any hint, Lao De

Hi,
thanks for that reply, after doing that I can not select this DD-view from sql-prompt anymore (which I don't wonder ;-). Can you tell me, what idea you had behind that test ?
I found another instance, where the procedure works and I will compare those privileges, but it's hard to sort out that complex structure of nested roles and sys_privs.
How ever, I will update here, when I found the missing privilege.

Select from a dynamically chosen table

Hi everyone,
I'm willing to retrieve information stored in a given column of a given table, both generated dynamically. Thus, I have a string S1 with the table name and a string S2 with a column name of this table.
My aim would be to do something like that :
+select single * into corresponding fields of X
from (S1)
where Y = 'SomeValue'.+
X being like a line of the table (S1)
Y being the column name stored in S2.
But for this, I need to fine a correct way to define X and Y from S1 and S2, which I failed to do until now. My first idea was to use field-symbols but it didn't help me. It might be quite easy or maybe impossible, I don't even know as my knowledge in ABAP is far from being excellent, but any reply would be welcome.
Best regards,
François

Select from database dynamically

Hello colleague,
i am trying to read a database whose name is dynamically identified. There are several fields but i am interested in one. I want all the entries for that field in the table. The field "trace_fct_id" is type SYSUUID_x(16). I want it to be populated in the CHAR32 field ie GUID.
LOOP AT lt_tabname INTO ls_tablename.
    CREATE DATA dref TYPE STANDARD TABLE OF (ls_tablename-name).
    ASSIGN dref->* TO <itab>.
    SELECT DISTINCT trace_fct_id FROM (ls_tablename-name) INTO CORRESPONDING FIELDS OF TABLE <itab>.
    MOVE <itab> TO et_func_ids.
ENDLOOP.
I get all the entries from the table but i just want to return the ID, and the move does not copy it in the internal table as the column name is different.
Could you please help?
Thanks in advance.

Performance problem with select from _DIFF view

Hi,
we have a versioned table with more then one million records. We use the DBMS_WM.SetDiffVersions procedure and select from DIFF view to get data differences between two workspaces. The problem is that the select from the DIFF view is very slow. I takes more than 15 minutes. Has anybody an idea why it consumes so much time? Is there any way how to improve it?
Thanks and regards
Ondrej

Hi,
This can be due to any number of things, but is typically caused by an inefficient optimizer plan. Make sure that statistics on the _LT table have been recently analyzed.
Also the following information would be useful:
1. What is the relationship of the workspaces that you are trying to compare (parent/child, children of the same parent, etc) ?
2. How many and of what type dml are being performed in the workspaces ?
3. What version of Workspace Manager are you using and what is the version of the database ?
4. What is the time needed to select from the _DIFF view based on the primary key ?
Regards,
Ben

What can be the possible reason for this.
Can we <b>NOT</b> select from maintainance views ?
Please advice.

How to bind to a dynamic View in UIX

I wish to have a UIX page access data from a dynamic View (i.e. the View is created at runtime). Since the View is not created at design time, I cannot create bindings for it in the UIX page's UIModel. Therefore, how do I reference this view in the UIX page?
Brad

Sanjay,
No -- but I'm experimenting with something simillar to what you mention. Actually, there is a way to iterate over each element if you made the childData attribute of your contents child of the messageChoice your rangeSet, i.e.:
<messageChoice>
<contents childData="${bindings.myIterator.rangeSet}">
<option text="${uix.current.myfield}"/>
</contents>
<messageChoice>
The problem is that this causes a problem with the subsequent submit, the current row, and what selection shows when the page is re-rendered. I am becoming more convinced because of this and some other things I've run into that there are either problems with using ViewLinks, or problems in UIX components where ViewLinks are involved. I'm pretty much abandoning use of ViewLinks altogether. I haven't seen much of anything work with them that isn't done exactly like tutorials and examples. And with regards to those, most tutorials and examples offer very little UIX help (most of them are JSPs), and even the ones that do have in-a-vaccuum style in-line databinding rather than database databinding (you'd think Oracle, a database company, might actually use database examples), which doesn't clarify a bunch of issues someone writing a reall application runs into.
As to an answer -- no unfortunately. Getting an answer to any ADF/UIX question is a time-consuming, frustrating, and most often fruitless process. Of my 45 some-odd posts on this forum, about 30 of them are unresponded-to posts.

MySQL: SELECT * FROM with a Variable from an HTML form

Hello,
I would like to insert the variable "find" from the HTML form below in the MySQL "SELECT * FROM" query beneath it. In other words, where the word "santafe" appears below, I would like to insert the variable "$find." But I can't quite get it to work. How do I do it?
Thanks in advance,
John
<form action="tsearch11.php" method="post">
<label>Enter Topic:
<input type="text" name="find" size="55"/>
<input type="hidden" name="searching" value="yes" />
<input type="submit" name="search" value="Search" />
</label>
</form>
Then, on tsearch11.php:
<?
mysql_connect("mysqlv3", "username", "password") or die(mysql_error());
mysql_select_db("sand2") or die(mysql_error());
$find = strip_tags($find);
$find = trim ($find);
$t = "SELECT * FROM santafe";
$y = mysql_query($t);
?>

Putting a form variable in a SQL query to look for table or column names requires an extra level of security. You need to create an array of the valid names, and check that the form variable is in that array.
$find = get_magic_quotes_gpc() ? stripslashes($_POST['find']) : $_POST['find'];
$find = mysql_real_escape_string(trim($find));
// create an array of valid table names
$tables = array('santafe', 'sanfernando', 'guadalupe');
// check that the variable is in the permitted array
if (in_array($find, $tables)) {
$t = "SELECT * FROM $find";
$y = mysql_query($t);
} else {
$error = 'Sorry, you selected an invalid table.';
In the page itself, check whether $y exists before using it. Otherwise display the error:
if (isset($y)) {
// display the results
} elseif (isset($error)) {
echo $error;

Where to find "Define field selection for Individual approval view" in ECC5

Hi,
I'm trying to find where I can configure the columns for the managers approval view in the backend in ECC5.
Time sheet>Setting for all user interfaces>Approval procedure>Approve working times> Define field selection for Individual approval view, doesn't appear to exist.
Any help appreciated.
Rob

Rob,
Try this:
IMG->Integration with Other mySAP.Com Components->Business Packages/Functional Packages->Manager Self-Service (mySAP ERP)->Working Time->Approve Working Time->Define Field Selection from Individual Approval View
Alternatively use SM34 and go to view cluster VC_PT_FIELD_SELECTION and enter the screen area as CTS.
Hope this helps. Good luck.
Regards,
Raj.
