Report-Dynamic Query

Hi,
I have a report based on 'PL/SQL function returning SQL query'. The attribute 'Sort' is selected for all column headings. This report has links to branch to other pages. Is it possible to clear the Last Sorted column session information and get the report sorted by the default column when returned to the report from another page? ie If I sort the report by third column and then click on a link to go to another page. If I click on 'Submit' of the second page and come back to the report, is it possible to get the report sorted by default column? I tried clearing the cache of the report page, when 'Submit' in the second page is clicked. Still I get the report sorted by the last sorted column.
Thanks for any help.

Hi Rekha,
You sort information are stored in your user's preferences. You need to reset those preferences to get back to your default sorting. To reset you could e.g. use a process type called "reset preferences (remove all preferences for current user)".
Hope this helps,
Marc

Jasper Reports Dynamic Query String

Hi guys. Could you help me out? I'm trying to create a program with jasper reports where the query string should be dynamic. Meaning the sql queries are to change depending on certain conditions. For example, Condition A executes sqlqueryA while condition B executes sqlqueryB. All on the same report. Although of course not at the same time. Is it possible? Could you give me a sample code? I have no idea at all. Thanks.

Dynamic Query in Report Builder

HI
I have a doubt:
I need to receive a parameter in my report and I need this parameter in the query, that means, I need to create a dynamic query depending on the value that I receive in one of the parameters that has my report.
I tried to use the resource of Searching by Reference Cursor tool, it is a blue circle in the Data Model View of Report Builder.
When I click this tool, I have an initial code, It is:
function QR_1RefCurDS return <RefCurType> is
begin
end;
In PL/SQL I tried to create to test and to play, this code:
Note: If you want to try only to test, it is simple and works:
create or replace package TEST_REFCURTYPE as
type refcurtype is ref cursor;
function TEST_REFCURTYPE (P_DATE_TO nvarchar2) return refcurtype;
end;
create or replace package body TEST_REFCURTYPE as
function TEST_REFCURTYPE (P_DATE_TO nvarchar2)
return refcurtype is
refcur refcurtype;
mysql varchar(1000);
begin
If P_DATE_TO is not null then
mysql := 'select '''|| P_DATE_TO ||''' from dual';
else
mysql := 'select sysdate from dual';
end if;
open refcur for mysql;
return refcur;
end;
end;
The problem is to pass this example of code to the function QR_1RefCurDS, I do not have a place to make reference to the type:
type refcurtype is ref cursor;
I tested the Unit Program in the Report Builder but it did not work, because all the code I try to write and create, for example in the Event BEFORE REPORT, it opens  Funcion( ) …., and I can not make reference to the type refcurtype inside a Function( ).
Would you help me please?
Or there is another way to make a dynamic query in the Report Builder?
Sorry for my English, I am a Brazilian living in Spain.

Hi,
you can use lexical parameters in your queries. Instead of a ":" use in the query before the parameter a "&". Then the parameter stands for a part of the query and not for a value (Bind parameter). In the before report trigger you can set this parameters. They can contain parts of SQL like order or where. Make sure that the default value for this lexical parameters are set to get a valid query.
SELECT ENAME, &p_column as COL2 FROM EMP &p_order
and in the trigger something like
IF :p_which_column = 1 THEN
:p_column := 'SAL'
ELSE

Generating Dynamic Query for Ad-Hoc Reports

Hello,
What is the best way to create a dynamic query to generate ad-hoc reports? I have a couple of ideas but not sure which would work best and be most flexible.
I would like our users to be able to check checkboxes for what data they would like returned in their report. The data would be pulled from a number of tables, 10+, depending on what pieces of data they checked.
Should I write one dynamic query, with a bunch of IF statements in it?
Should I write many individual queries and then join them together in a temp query?
Should I create a temp table on our SQL server which contains the data from all of the tables; then query that? (I am worried about data being out-of-date with this option.)
Which one of these solutions should I go with or is there a better solution that I am not considering?
Thanks for the help.
Josh

Do you mean a Stored Procedure? Would the Stored Procedure then have one query on it with a bunch if IF statements? Maybe a bad example, but something like this?
Yep.
I haven't written a proc for a coupla years (I have DB people to do that for me now, bless 'em), but every DB is different, so the approach will vary depending on what DB you have. It's perhaps time to buy a book or do a google or something.

Dynamic query to produce crosstab/pivot report

Hello,
I've not been able to find any examples similar to my situation but perhaps I'm using the wrong search phrases...
I'm basically trying to create a cross-tab type report based on a dynamic query (since I do not know how many accounts a person has):
select ' SELECT x.name, x.type, ' from dual
union
select ' max(decode(x.account,'''||m.account||''',x.amount,null)) as "'||substr(s.proj||' '||m.account,1,30)||'",'
from db1.manager m, db1.person p, pi.charges c, db1.status s
where m.manager_id = p.id
   and M.ACCOUNT_ID = C.ACCT_ID
   and M.ACCOUNT_STRING = S.project
   and C.JNL = (select max(id) from db1.journ j where j.TYPE ='M')
   and p.username = :username
   and nvl(M.END_DATE, sysdate +1) >= sysdate
group by m.account, s.proj
union
select 'sum(x.amount) grand_total from (select m.account, c.name, c.type, c.amount '
          ||'from db1.manager m, db1.person p, pi.charges c '
          ||'where m.manager_id = p.id '
          ||'and p.username = :P68_PRINC '
          ||'and c.acct_id = m.account_id '
          ||'and c.jnl = (select max(id) '
          ||'from db1.journ j where j.TYPE =''M'')) x '
          ||' group by type, name' from dualThe output from this query for the particular manager I selected is:
SELECT x.name, x.type,
max(decode(x.account,'12012',x.amount,null)) as "Internal 12012",
max(decode(x.account,'17929',x.amount,null)) as "Staged 17929",
max(decode(x.account,'18054',x.amount,null)) as "Help Software 18054",
max(decode(x.account,'3428',x.amount,null)) as "Mow 3428",
max(decode(x.account,'3428',x.amount,null)) as "Mow 3428_1",
max(decode(x.account,'3508',x.amount,null)) as "Stampede 3508",
max(decode(x.account,'9102',x.amount,null)) as "Open Collaborative 9102",
sum(x.amount) grand_total
from (select m.account, c.name, c.type, c.amount
from db1.manager m, db1.person p, pi.charges c
where m.manager_id = p.id
    and p.username = :P68_PRINC
    and c.acct_id = m.account_id
    and c.jnl = (select max(id)
   from db1.journ j where j.TYPE ='M')) x
group by type, nameThis query generates another query that ultimately produces the report below (please pardon the alignment) that I want to see on a report page.

If so, how does that get set up?
Thanks in advance!
~Jake

This solution works in that it generates the proper query. I can copy the query (from debug mode) and paste it in TOAD and it works perfectly. However, in the report page it tells me: "report error:ORA-01403: no data found".
I found this thread: report error: ORA-01403: no data found when SUM columns
I did have a couple other regions on the page (previous attempts) that were hidden so I deleted them completely. Still no luck.
I am also summing up several columns...if that has anything to do with it.
Does anyone have any suggestions?
Thanks again!!!

Create dynamic report or query for piece count

Hi abaper's
This is a very straight forward requirement. so please give me code
First you have to get the corresponding plant from table T320 for the given warehouse numbers in the selection screen.
1.     Get the sum of order qty of sales orders from the sales order tables      for the given warehouse(Plant), distribution channel and the give date      range.
2.     Get the confirmed transfer orders qty from the TO master table where      TO confirmation date is in the given date range and WH number.
3.     Get the total PGIed qty from the delivery master table where PGI'ed      date in the given date range, shipping point is in the corresponding      plant of the WH and for the given distribution channel.
As you are going to use the major tables please try to write the select commands effectively to avoid further performance issues.

How to improve the performance fo this code.....this very urgent.

Interactive report based on dynamic query

Hello
I am using Apex 4.1 and have a requirement to create an interactive report based on a dynamic query. This option is available in Classic report but in Interactive this feature is not there. Tried using collections or just a view (thought of changing the view definition during "On load", but structure of the report is already defined based on the definition of the view at design time).
Is there any way of achieving this?
Appreciate any help!
Thanks

Dynamic query table for report based on LOV selected

Hi,
Need some suggestion and guidance how to dynamically query table via lov for report .
Scenario:
Table, TABLE_LIST, has tablename (table in DB) and filter (for where clause) column. The TABLENAME_LOVE is derived from table TABLE_LIST.
SELECT TABLENAME D, TABLENAME R FROM TABLE_LIST
In Page 2,a page select list item,P2_TABLENAME to use TABLENAME_LOV
All data in tables in the table_list have identical structure (columns, triggers, primary key, and so on).
I want to have the report region query from the table based on selected LOV.
Example,
Tablename Filter
TB1
CD2 ACTIVE='Y'
When select TB1, the report regin will query based on TB1.
When select CD2, the report regin will query based on CD2 WHERE ACTIVE='Y'
Question:
How can I query based on &P2_TABLENAME. WHERE &P2_FILTER.
Like
select col1, col2 from &P2_TABLENAME WHERE &P2FILTER
Greatly appreciate any suggestion and some guidance.
Tigerwapa

Hi,
You should always post your Apex version, DB version and other information as suggested in the FAQ.
And the moment you talk report you should state whether it is IR or Classic.
As for your query, have you explored the Report type "SQL Query (PL/SQL function body returning SQL query)" ?
That might be a good fit for what you are trying to achieve.

Parameter in form for dynamic query in report

Hello,
I want to send parameters to report for replacing a dynamic query. I don't know how to make it...
1.I want my select statement like
select * from emp
&p_where_clause
2.I want to transfer parameters to report to replace the &p_where_clause.
3.I know I should create a parameter list first, and then use add_parameter built-in to add the parameter, but what I don't know is the correct format of the add_parameter statement.
4.I know the common format is add_parameter(paramlist,'TEXT_PARAMETER',value) , is it the same format if I want to transfer a select statement to report such as "where deptno in ('25','28','30')" for replacing &p_where_clause in report?
Thanks in advance
Joseph

I appreciate your reply, but I am still a little confused...
Actually, I want to pass the where clause to report by different condition. Such as when the user choose the deptment 1, then I can transfer the "where dept_no = '1' and empno > 500", or user choose the deptment 2, I can transfer "where dept_no = '2' and company = '0001'". What I want is to pass different where clause to report according to different condition.
So is it right the statement should be like
DECLARE
vWhere1 varchar2 := 'where dept_no = "1" and empno > 500';
vWhere2 varchar2 := 'where dept_no = "2" and company = "0001"';
BEGIN
IF choose = 1 THEN
ADD_PARAMETER(&P_WHERE_CLAUSE, TEXT_PARAMETER, vWhere1);
ELSIF choose = 2 THEN
ADD_PARAMETER(&P_WHERE_CLAUSE, TEXT_PARAMETER, vWhere2);
END IF;
END;
THANKS AGAIN!!

Dynamic query in updatable report

I have generated a updatable report with the folowing select:
select
"INSTALLATIEID",
"INSTALLATIEID" INSTALLATIEID_DISPLAY,
"CO_DRUK" druk,
"CO_H2O" h2o,
"CO_O2" o2,
"CO_O2_11" o2_11,
"CO_TEMP" temp
from "#OWNER#"."CORRECTIE"
The table correctie has above the 50 columns (the same columns for different components) so I want to change the query in:
select
"INSTALLATIEID",
"INSTALLATIEID" INSTALLATIEID_DISPLAY,
"&P50_COMP._DRUK" druk,
"&P50_COMP._H2O" h2o,
"&P50_COMP._O2" o2,
"&P50_COMP._O2_11" o2_11,
"&P50_COMP._TEMP" temp
from "#OWNER#"."CORRECTIE"
The item P50_COMP will be filled with a default value and is a select list with submit.
The problem is when I change the query in the above way, the query cannot be parsed and I cannot applay the changes without parsing the query.
Also not when I use Generic Column Names (parse query at runtime only)
Can somebody help me with this problem.

Fred,
You should switch to a PL/SQL Function Body Returning SQL Statement (Dynamic Query) in order to achieve this. Your Function would look like this:
declare
l_sql varchar2(32767);
begin
l_sql := 'select
"INSTALLATIEID",
"INSTALLATIEID" INSTALLATIEID_DISPLAY,
"' || :P50_COMP || '._DRUK" druk,
"' || :P50_COMP || '._H2O" h2o,
"' || :P50_COMP || '._O2" o2,
"' || :P50_COMP || '._O2_11" o2_11,
"' || :P50_COMP || '._TEMP" temp
from "#OWNER#"."CORRECTIE"';
return l_sql;
end;Thanks,

Creating Crystal Reports Dynamically from an incoming SQL query

Hi,
I have a requirement where a sql query will be entered by the user in a text box and in the back end java code, i have to create a crystal report dynamically based on that sql query and show it in the crystalviewer object.
For example if the user writes "select x,y from xtable ", i should be able to create a report with 2 fields, and if the user says "select x,y,z from xtable" then i should be able create and show a report with 3 fileds...thsi report creation should be done in the click event.
Is this possible in java? I have found something similar in .NET... pls have a look at this
http://vb.net-informations.com/crystal-report/dynamic_crystal_report_from_sql_query_string.htm
Thanks,
Preethi

Hi Preethi,
Can you please share the steps with me? I am also looking for dynamic SQL being applied to the crystal report.
Thank you so much for your help in advance.

Janakiram D.

Dynamic query report problem

I have followed the tutorial in on dynamic query and created a region where the type is SQL Query (PL/SQL function body returning SQL Query)
The source is
declare
q varchar2(4000);
teatid NUMBER := :P305_TARGET_ID;
begin
wwv_flow.debug('teatid = ' || teatid);
q:=' select f.id, ';
q:=q||' f.eat_id ';
q:=q||' from xmlTransactions f ';
q:=q||' where f.eat_id = ' || teatid; -- I've also tried putting :P305_TARGET_ID here
wwv_flow.debug('sql = ' || q);
return q;
end;
I have chosen "Use Generic Column Names...".
When I run the page, I get NO ROWS FOUND. However, when I cut and paste the SQL statement printed out by the debug statement and run it, it returns rows. Both debug statements print correct values.
I'm not sure what the problem is here, but basically, I want to do a query where I substitute a value passed into the page from another page.
In this case the value in P305_TARGET_ID is passed in via a button spawning a popup as in var url = 'f?p=&APP_ID.:305:&APP_SESSION.::::P305_TARGET_ID:' + targetID;
APEX version is 3.0.1.00.08
Thank you.
- JohnW

Hi, JohnW
I don't understand why you use a dynamic query for that.
A "direct" SQL query like this :
select f.id,f.eat_id from xmlTransactions f where f.eat_id=:P305_TARGET_ID;
should work.

Help on performance with dynamic query

Hi All,
We are using SQL Server 2008R2. In our one of report we are using Dynamic query and it is taking more time to retrieve the data. to retrieve 32 records it is taking 13-15 secs. In my observation in a table variable, created more than 60 columns. In
the SP called one more sp with insert statement.
Please let me know how i can improve performance of the SP.
I know that i have to provide the SP for observation but unfortunately I cannot provide the SP. Please guide me how i can achieve this .
I tried with temp tables by creating indexes on temp tables but i couldn't find improvement in performance.
Waiting for valuable replies.

First of all a "dynamic query" is not "a query" - it is a multitude of them. Some of them may be fast, others may be slow.
There is of course no way we can give specific suggestions without seeing the code, the table and index definitions etc.
We can only give the generic suggestions. As for the code, make sure that you are using parameterised SQL and you are not building a complete SQL string with parameters and all. If nothing else, this helps to make the code more readable and maintainable.
It also protects you against SQL injection. And it also helps to prevent performance issue due to implicit conversion.
You will need to look at the query plan to see where the bottlenecks may be. You should look at the actual query plan. Note that the thickness of the arrows are more relevant than the percentages you see; the percentages are only estimates, and estimates
are often off. Next step is to see if you can add indexes to alleviate the situation. You should also analyse if there are problems in the query, for instance indexed columns that are entangled in expression. If you are using views, make sure that you don't
have views built on top of views etc. This can often result a table appearing multiple times in a query, when one would be enough.
