Dynamic sql query for report based on user input

Hi everyone,
I have built custom search fields (name, date born, gender etc.) in the search region and in the results region a report need to be displayed.
Now I'm not very experienced with Apex or Oracle sql, but could anyone telll me how to first check if a user filled in a field and then build a query based upon what field the user filled in to submit.
Any help would be appreciated, thanks in advance.
regards,
Cleo

Hi, Cleopatra. Welcome to OTN!
If you don't have too many fields instead of checking to see if they're filled in you can use OR conditions in yoru WHERE_CLAUSE to check for NULLS to ignore NULLS, something like (you will have to test this carefully!)
AND some_column = NVL(:P24_1,some_column)the idea being that if the field is NULL then the column will match itself - in this case assuming the column itself does not have a null value

Proxy to JDBC scenario need dynamic sql query for sender .

Hi Experts,
I am developing proxy to jdbc scenario. in this i need to pass dynamic sql query whre we are passing classical method like below.
while we are passing select stmt in constant and mapped with access field and key field mapped with key field.
MY requirement is like instead of passing select stmt in constant where i can generate dynamically and passed in one field and mapped with access field.

Hi Ravinder,
A simple UDF or use of graphical mapping functions in most cases should provide you everything you need to construct a dynamic SQL statement for your requirement.

Help with PL/SQL returning SQL query for Report

Hi
I have got a report which I have formatted as PL/SQL function body returning SQL query.
I have the following code
declare
q VARCHAR2(32000); -- query
w VARCHAR2(4000) ; -- where clause
begin
q := 'select min(identified_date) first_identified,' ||
' max(actual_resolution_date) last_closed,' ||
' count("HELPDESK_CALL_ID) total_issues,' ||
' from tbl_helpdesk_calls';
if :P9_call_type != '-1' then
w := 'HELPDESK_CALL_TYPE_ID = :P9_call_type';
end if;
q := q || ' WHERE '|| w;
return q;
end;
When I apply changes I get this error message
Query cannot be parsed within the Builder. If you believe your query is syntactically correct, check the ''generic columns'' checkbox below the region source to proceed without parsing. ORA-00972: identifier is too long
Any Idea where I maybe going wrong?

thanks its compiling now but when I run the page I get this error message in the reports region
failed to parse SQL query:
ORA-00933: SQL command not properly ended
This is my code that I have at the momment.
declare
q VARCHAR2(32000); -- query
w VARCHAR2(4000) ; -- where clause
we VARCHAR2(1) := 'N'; -- identifies if where clause exists
begin
q := 'select min(identified_date) first_identified,' ||
' max(actual_resolution_date) last_closed,' ||
' count(HELPDESK_CALL_ID) total_issues,' ||
' sum(decode(status,''Open'',1,0)) open_issues, ' ||
' sum(decode(status,''On-Hold'',1,0)) onhold_issues,' ||
' sum(decode(status,''Closed'',1,0)) closed_issues,' ||
' sum(decode(status,''Open'',decode
(priority,''High'',1,0),0)) open_high_prior,' ||
' sum(decode(status,''Open'',decode
(priority,''Medium'',1,0),0)) open_medium_prior, '||
' sum(decode(status,''Open'',decode
(priority,''Low'',1,0),0)) open_low_prior '||
' from tbl_helpdesk_calls';
if :P9_call_type != '-1' then
w := 'where HELPDESK_CALL_TYPE_ID = :P9_call_type';
we := 'Y';
end if;
if we = 'Y' then
q := q ||w;
end if;
return q;
end;
I have a select list with a list of reports. what I am trying to do build an sql depending on what the :p9_call_type value is. -1 represents the display value of -All Reports- so if the user selects all reports it should display all results thus removing the where clause. However as my code stands when I user clicks on all reports he get the correct results for all reports. If the user selects anything else they get the error message above.

Sql query for report?

Hi all
I have one big table with column:
code,street,data_type,credit,debt,saldo,date
I was creating query like
select sum(saldo),code from tableA where data_types=1 and date <'201010' group by code
but cant expand this query to be as report like
COLUMN1 COLUMN2 COLUMN3 COLUMN4
sum(saldo) -where type=1 and date = '201201', sum(saldo) where type=2, sum(saldo) where date ='201205' , code
whats best solution to report sums for diferent data_types on one line with just one code per lines?

Displaying different reports based on user input.

Hi,
I have a requirement to display the invoiced amount and Ago amount on a dashboard. The ago amount will be dynamic in that if user selects the prompt 'compare with' as previous day, it should display day ago amount along with todays amount. It he chooses month, then it should display this month's amount and previous month's amount.
Is there a way I can achieve this on a dashboard?
Thanks,
Vivek.

Use guided navigation. And you need to have 2 reports (one for day level and the other for month level, eac has own AGO part). And some reports for guided navigation conditions.

Get a insert session value for SQL query at report

Hi friends
I created a global temp table and procedure to support web search form.
and a search result report. The procudure
gets search result from multip tables and
insert into temp table --recordsearch. I can get value from temp table by call procedure
at SQL*Plus.
However, I can not get this value by web report.
How can I get this insert session value and pass to SQL query for report?
Thanks,
Newweb
CREATE GLOBAL TEMPORARY TABLE recordsearch
(emp_id          VARCHAR2(200),
ssn               VARCHAR2(9),
fname          VARCHAR2(200),
lname           VARCHAR2(200),
m_name          VARCHAR2(200)
) ON COMMIT PRESERVE ROWS;

it possible that your web form does not have a persistent, dedicated connection. if you have connection pooling for example, multiple sessions will see the same instance of the GTT, so if one deletes it, then nobody sees it (or you can see others data). if the connections are not persistent, then they can disconnect between calls, deleting the GTT table.

Problem writing a sql query for a select list based on a static LOV

Hi,
I have the following table...
VALIDATIONS
ID          Number     (PK)
APP_ID          Number
REQUESTED     Date
APPROVED     Date
VALID_TIL     Date
DEPT_ID          Number     (FK)
I have a search form with the following field item variables...
P11_DEPT_ID (select list based on dynamic LOV from depts table)
P11_VALID (select list based on static Yes/No LOV)
A report on the columns of the Validations table is shown based on the values in the search form. So far, my sql query for the report is...
SELECT v.APP_ID,
v.REQUESTED,
v.APPROVED,
v.VALID_TIL,
d.DEPT
FROM DEPTS d, VALIDATIONS v
WHERE d.DEPT_ID = v.DEPT_ID(+)
AND (d.DEPT_ID = :P11_DEPT_ID OR :P11_DEPT_ID = -1)
This query works so far. My problem is that I don't know how to do a search based on the P11_VALID item - if 'yes' is selected, then the VALID_TIL date is still valid. If 'no' is selected then the VALID_TIL date has passed.
Can anyone help me to extend my query to include this situation?
Thanks.

Hello !
Let's have a look at my example:create table test
id        number
,valid_til date
insert into test values( 1, sysdate-3 );
insert into test values( 2, sysdate-2 );
insert into test values( 3, sysdate-1 );
insert into test values( 4, sysdate );
insert into test values( 5, sysdate+1 );
insert into test values( 6, sysdate+2 );
commit;
select * from test;
def til=yes
select *
from test
where decode(sign(trunc(valid_til)-trunc(sysdate)),1,1,0,1,-1)
       =decode('&til','yes',1,-1);
def til=no
select *
from test
where decode(sign(trunc(valid_til)-trunc(sysdate)),1,1,0,1,-1)
       =decode('&til','yes',1,-1);
drop table test; It's working fine, I've tested it.
The above changes to my first idea I did because of time portion of the DATE datatype in Oracle and therefore the wrong result for today.
For understandings:
1.) TRUNC removes the time part of DATE
2.) The difference of to date-values is the number of days between.
3.) SIGN is the mathematical function and gives -1,0 or +1 according to an negative, zero or positiv argument.
4.) DECODE is like an IF.
Inspect your LOV for the returning values. According to my example they shoul be 'yes' and 'no'. If your values are different, you may have to modify the DECODE.
Good luck,
Heinz

Update Field On Change For A SQL Query (updateable report)

Hi,
I'd like to request help from anyone with ideas on how to solve this.
We are using APEX 4.2, 10GR2, RedHat5.
I have a report that comes from SQL Query (updateable report).
I'm using the apex_item.text and apex_item.hidden on fields.
I'm using a button to submit and after submit process to add some logic that I need.
There could be 1 - 10 records in the report.
There is only 1 field that is needed to enter a value, but the value of this field determines the value of another field.
I think that I can do this with a submit button and an after submit process where I loop through all the records. I think I have this handled.
This is the question
When the value of that field is changed then the value of another field in the same row changes immediately.
Is this possible?
All the examples I've seen so far are for a single record and that doesn't work for us.
I guess this is a MRU process but I haven't seen an example where a dynamic action is possible on a Multi Row Update.
Could anyone direct me to where I can see an example or help me get directions?
I appreciate all your help an comments and I thank you in advance.

Yes why not...what you looking for is a ajax call
See {message:id=10390979}
Please note:-you can also do this as a dynamic action as shown below
Event: Change
Selection type: jQuery Selector
jQuery Selector: input[name="f01"]
True action with Execute JavaScript Code and put all code inside the test funtion, you may need to amend the code to use this.triggeringElemnt in place of this

Flash chart with dynamic sql query does not display

Hi,
In my schema SIVOA I have a lot of tables declared like this :
CREATE TABLE "SIVOA"."EVV_xxxx"
   (     "CLEF_VAR" NUMBER(4,0),
     "DATE1" DATE,
     "VALEUR" NUMBER(16,8) Only the last part of the name changes "xxxx". For example E009, E019, etc....
I am making a chart page with report and want the user to select a name of a table and I will display using dynamic sql query, the table report and chart.
P184_ENAME is a select list returning the last part of the name of the table, fro example 'E009', 'E019', etc.
P8_CLEF_VAR is an item containing a value. This value is a key retrieved like this :SELECT CLEF_VAR
FROM SIVOA.SITE_ECHELLE
WHERE SITE = :P184_ENAMEI built a classic report using a sql dynamic function :DECLARE
x VARCHAR2 (4000);
BEGIN
x := 'SELECT NULL, DATE1, VALEUR FROM SIVOA.EVV_'
|| UPPER(:p184_ename)
|| ' WHERE CLEF_VAR = :p8_clef_var' ;
RETURN (x);
END;:p8_clef_var is an itme containing the value '4544'.
This works perfectly fine !
When I use this sql fucytion into a flash chart it does not work. I get this message "No data found".
I do not understand why a the report get a result and not the chart !
But if i hard-code the number of the CLEF_VAR instead of fetching it from :p8_clef_var I get a nice chart ! Go figure !DECLARE
x VARCHAR2 (4000);
BEGIN
x := 'SELECT NULL, DATE1, VALEUR FROM SIVOA.EVV_'
|| UPPER(:p184_ename)
|| ' WHERE CLEF_VAR = 4544 ' ;
RETURN (x);
I cannot stay with the key (CLEF_VAR) hard-coded unformtunately !
My question is how to get the chart displaying properly ??
Thank you for your kind answers.
Christian

Alex,
Using your request, with the classic report I get results (data), but I get the same message with the Flash chart : "No data found" ! I don't know how to investigate this. i tried many things but nothing works.
Christian
PS I tried this :
DECLARE
   X   VARCHAR2 (4000);
BEGIN
x := 'SELECT NULL, DATE1, ROUND(VALEUR,2) FROM SIVOA.EVV_'
      || UPPER (:p184_ename) ||
      ' WHERE CLEF_VAR = '
      || :p8_clef_var ||
      ' AND DATE1 BETWEEN TO_DATE ('''
||:P8_DATE_DEBUT||''', ''DD/MM/YYYY HH24:MI'') AND TO_DATE ('''
||:P8_DATE_FIN||''', ''DD/MM/YYYY HH24:MI'')'
RETURN (X);
END; But it does not work either. I could find that the SLQ syntax generated is good becaus I put it into an item which display the return done by the pls/sql.
What is sttange also with the classic report is that if I do click on next or previous to see another rows, I get the message "No data found". If I try to export the report I get an excel file with "No data fouid".
Does anybody already tried my "need" here ? i find strange thant I should not be the firs one trying to get a report an tables which name would be "dynamic".
Tahnk you.

SQL Query (updateable report) Region - Conditionally Hide and Set Values

SQL Query (updateable report) Region - Conditionally Hide and Set Values
Outline of requirement :-
Master / Detail page with Detail updated on same page using SQL Query (updateable report).
The detail region has the following source
SELECT item_id,
       contract_id,
       CASE WHEN hardware_id IS NOT NULL THEN
               'HA'
            WHEN backup_dev_id IS NOT NULL THEN
               'BD'
            WHEN hardware_os_id IS NOT NULL THEN
               'HS'
       END item_type,
       hardware_id,
       backup_dev_id,
       hardware_os_id
FROM   "#OWNER#".support_items
WHERE contract_id = :P26_CONTRACT_IDThe table support_items implements arced relationships and has the following columns
CREATE TABLE SUPPORT_ITEMS
ITEM_ID         NUMBER                        NOT NULL,
CONTRACT_ID     NUMBER                        NOT NULL,
HARDWARE_ID     NUMBER,
BACKUP_DEV_ID   NUMBER,
HARDWARE_OS_ID NUMBER
)A check type constaint on support_items ensures that only one of the fk's is present.
      (    hardware_id    IS NOT NULL
       AND backup_dev_id IS NULL
       AND hardware_os_id IS NULL
OR    (    hardware_id    IS NULL
       AND backup_dev_id IS NOT NULL
       AND hardware_os_id IS NULL
OR    (    hardware_id    IS NULL
       AND backup_dev_id IS NULL
       AND hardware_os_id IS NOT NULL
      )    Hardware_Id is a FK to Hardware_Assets
Backup_dev_id is a FK to Backup_Devices
Hardware_os_id is a FK to Hardware_op_systems
The Tabular Form Element based on item_type column of SQL query is Displayed As Select List (based on LOV) referencing a named list of values which have the following properties
Display Value     Return Value
Hardware Asset    HA
Backup Device     BD
Computer System   HSThe Tabular Form Elements for the report attributes for hardware_id, backup_dev_id and hardware_os_id are all Displayed As Select List (Based on LOV).
What I want to do is only display the Select List for the FK depending on the value of the Select List on Item Type, e.g.
Item_Type is 'HA' then display Select List for hardware_id, do not display and set to NULL the Select Lists for backup_dev_id and hardware_os_id.
Item_Type is 'BB' then display Select List for backup_dev_id, do not display and set to NULL the Select Lists for hardware_id and hardware_os_id.
Item_Type is 'HS' then display Select List for hardware_os_id, do not display and set to NULL the Select Lists backup_dev_id and hardware_id.
There are properties on elements to conditionally display it but how do we reference the values of the SQL query Updateable region? they are not given a page item name?
Also on the Tabular For Elements there is an Edit tick against a report item - however when you go to the Column Attributes there is not a property with which you can control the Edit setting.
What's the best way of implementing this requirement in APEX 3.1?
Thanks.

Welcome to the forum: please read the FAQ and forum sticky threads (if you haven't done so already), and update your profile with a real handle instead of "user13515136".
When you have a problem you'll get a faster, more effective response by including as much relevant information as possible upfront. This should include:
<li>Full APEX version
<li>Full DB/version/edition/host OS
<li>Web server architecture (EPG, OHS or APEX listener/host OS)
<li>Browser(s) and version(s) used
<li>Theme
<li>Template(s)
<li>Region/item type(s) (making particular distinction as to whether a "report" is a standard report, an interactive report, or in fact an "updateable report" (i.e. a tabular form)
With APEX we're also fortunate to have a great resource in apex.oracle.com where we can reproduce and share problems. Reproducing things there is the best way to troubleshoot most issues, especially those relating to layout and visual formatting. If you expect a detailed answer then it's appropriate for you to take on a significant part of the effort by getting as far as possible with an example of the problem on apex.oracle.com before asking for assistance with specific issues, which we can then see at first hand.
I have a multi-row region that displays values and allows entries in a number of fields.Provide exact details of how this has been implemented. (An example on apex.oracle.com is always a good way to do this.)
I should like the fields to be conditional in that they do not permit entry, but still display, if certain conditions apply (e.g. older rows greyed out). Can this be done? Almost anything can be done, often in multiple ways. Which are appropriate may be dependent on a particular implementation, the skills available to implement it, and the effort you're willing to expend on it. Hence it's necessary to provide full details of what you've done so far...

How to add column dynamically based on user input in oracle?

how to add column dynamically based on from_date to to_date?
Thanks and Regards,

You cannot add columns dynamically. But you can define a maximum number of numbers and then hide unused columns in your form useing SET_ITEM_PROPERTY(..,VISIBLE, PROPERTY_FALSE);

Best way to spool DYNAMIC SQL query to file from PL/SQL [Package], not SqlPlus
I'm looking for suggestions on how to create an output file (fixed width and comma delimited) from a SELECT that is dynamically built. Basically, I've got some tables that are used to define the SELECT and to describe the output format. For instance, one table has the SELECT while another is used to defined the column "formats" (e.g., Column Order, Justification, FormatMask, Default value, min length, ...). The user has an app that they can use to customize the output...which leaving the gathering of the data untouched. I'm trying to keep this formatting and/or default logic out of the actual query. This lead me into a problem.
Example query :
SELECT CONTRACT_ID,PV_ID,START_DATE
FROM CONTRACT
WHERE CONTRACT_ID = <<value>>Customization Table:
CONTRACT_ID : 2,Numeric,Right
PV_ID : 1,Numeric,Mask(0000)
START_DATE : 3,Date,Mask(mm/dd/yyyy)The first value is the kicker (ColumnOrder) as well as the fact that the number of columns is dynamic. Technically, if I could use SqlPlus...then I could just use SPOOL. However, I'm not.
So basically, I'm trying to build a generic routine that can take a SQL string execute the SELECT and map the output using data from another table to a file.
Any suggestions?
Thanks,
Jason

You could build the select statement within PL/SQL and open it using a cursor variable. You could write it to a file using the package 'UTL_FILE'. If you want to display the output using SQL*Plus, you could have an out parameter as a ref cursor.
