Sql query in apex

Hi all,
i have table with following fields start_time, end_time
and data is 25/01/2010 12:00,25/01/2010 12:48
i am running a sql query to get info about time spent
Select end_time - start_time
from table
but it is giving .033333333
I want follwing result
time_spent
00:48 min
please help

Omy,
The solution I gave above had an error. The hours and minutes component both had the difference in them.
That would have been useful if you only needed the hours component (2) or the minutes component (150 minutes-- 2 hours and 30 minutes..).
To make sure we get only the hours component and minutes component in the respecive sections, we can make use of the mod function..
1 select start_date,
2         end_date,
3         (end_date-start_date) usual_diff,
4         trunc(end_date-start_date) || ' days ' ||
5         mod(trunc((end_date-start_date)*24),24) || ' hours ' ||
6         mod(trunc((end_date-start_date)*24*60),60) || ' minutes ' ||

Changing font color in a report using SQL query for APEX 5.0

Hello,
I am testing APEX 5.0 in my testing environment to see if I can migrate my internal apps from 4.2 to 5.0.
How can I change the font color in a field based in the SQL query? I know how to do it in 4.2 but I can't find the same in 5.0.
Thanks,

Well, I used to put the html tags in the select as text getting the color value depending a CASE , then I had to change the Display attribute for the column in the report as "Display as text (espace special characters...)".
I found an old post here: https://tylermuth.wordpress.com/2007/12/01/conditional-column-formatting-in-apex/ and this method still worked for me in APEX 5.0
Thanks anyways

Change column order updateable sql query report APEX 4

Hi all,
I have a master detail page. Detail is SQL Query (updateable report)
I want to change the column order but seems not possiible anymore in A4.
In A3... on the right side of the report attributes it was possible to move columns up or down.
path is Home>>Application Builder>>Application nnn >>Page xx >>Report Attributes
It seems that A4 the move up or down functionality is hidden or the region is to small with no horizontal scrollbar.
Is there a work_aorund?
This is also the case when the pages are displayed in icon view when showing all pages using.
Home >> Application Builder >>Application
Most right icons are hidden after the about and task regions.
The work-around here is to display the pages in report or detail view
Maybe a fix needed for APEX4?
have nice weekend!

How do I query off a pl/sql funtion that returns an sql query in apex.

I built a function that a returns a good sql query. I verified the out put of my function works when I manually entered into the SQL Commands.
Is it possible to build a report off of this query. My attempt failed with the following error.
failed to parse SQL query:
ORA-00933: SQL command not properly ended
I am sure the query generated is correct. Like I mentioned, I was able to use in the sql command succesfully.
Thanks,

PL/SQL function body returning SQL query - ORA-06502: PL/SQL: numeric or value error

I'm attempting to dynamically generate a rather large SQL query via the "PL/SQL function body returning SQL query" report region option. The SQL query generated will possibly be over 32K. When I execute my page, I sometimes receive the "ORA-06502: PL/SQL: numeric or value error" which points to a larger than 32K query that was generated. I've seen other posts in the forum related to this dynamic SQL size limitation issue, but they are older (pre-2010) and point to the 32K limit of the DNS (EXECUTE IMMEDIATE) and DBMS_SQL. I found this post (dynamic sql enhancements in 11g) which discusses 11g no longer having the 32K size limitation for generating dynamic SQL. Our environment is on 11gR2 and using ApEx 4.2.1. I do not know which dynamic SQL method -- DNS or DBMS_SQL -- ApEx 4.2.1 is using. Can someone clarify for me which dynamic SQL method ApEx uses to implement the "PL/SQL function body returning SQL query" option?
As a test, I created a page on apex.oracle.com with a report region with the following source:
declare
l_stub varchar2(25) := 'select * from sys.dual ';
l_sql clob := l_stub || 'union all ';
br     number(3) := 33;
begin
while length ( l_sql ) < 34000 loop
    l_sql := l_sql || l_stub || 'union all ';
end loop;
l_sql := l_sql || l_stub;
for i in 1 .. ceil ( length ( l_sql ) / br ) loop
    dbms_output.put_line ( dbms_lob.substr ( l_sql, br, ( ( i - 1 ) * br ) + 1 ) );
end loop;
return l_sql;
end;
The dbms_output section is there to be able to run this code in SQL*Plus and confirm the size of the SQL is indeed larger than 32K. When running this in SQL*Plus, the procedure is successful and produces a proper SQL statement which can be executed. When I put this into the report region on apex.oracle.com, I get the ORA-06502 error.
I can certainly implement a work-around for my issue by creating a 'Before Header' process on the page which populates an ApEx collection with the data I am returning and then the report can simply select from the collection, but according to documentation, the above 32K limitation should be resolved in 11g. Thoughts?
Shane.

What setting do you use in your report properties - especially in Type and in Region Source?
If you have Type="SQL Query", then you should have a SELECT statement in the Region Source. Something like: SELECT .... FROM ... WHERE
According to the ERR-1101 error message, you have probably set Type to "SQL Query (PL/SQL function body returning SQL query)". In this situation APEX expects you to write a body of a PL/SQL function, that will generate the text of a SQL query that APEX should run. So it can be something like:
declare
mycond varchar2(4000);
begin
if :P1_REPORT_SEARCH is not null THEN
mycond:='WHERE LAST_NAME like :P1_REPORT_SEARCH ||''%''';
end if;
return 'select EMPLOYEE_ID, FIRST_NAME, LAST_NAME from EMPLOYEES ' ||mycond;
end;
And for escaping - are you interested in escaping the LIKE wildcards, or the quotes?
For escaping the wildcards in LIKE function so that when the user enters % you will find a record with % and not all functions, look into the SQL Reference:
http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14200/conditions007.htm
(You would than need to change the code of your function accordingly).
If you are interested in escaping the quotes, try to avoid concatenating the values entered by the user into the SQL. If you can, use bind variables instead - as I have in my example above. If you start concatenating the values into the text of SQL, you are open to SQLInjection - user can enter anything, even things that will break your SQL. If you really need to allow users to choose the operator, I would probably give them a separate combo for operators and a textfield for values, than you could check if the operator is one of the allowed ones and create the condition accordingly - and than still use bind variable for inserting the filtering value into the query.

How to run a sql query from a button in apex 3.0

Hi,
I am brand new and went through/installed the obe project tracker. I have need to create a simple application that displays a result (2 fields, name and license number) based on two parameters (dob and login id) which all are stored in 1 table in the database. I could this very simply in VB or VB.net but have no idea how to do it in apex.
Please provide guidance,
Thank you,
Tom

Hi Tom,
Sounds like a report region will satisfy your requirements.
Create a new report region on one of your pages.
Choose SQL Report and give the region a title.
When you get to the "Enter SQL Query or PL/SQL function returning a SQL Query:" step, type:
SELECT name, license_number
FROM <insert_your_table_name_here>
WHERE dob = :P<n>_dob
AND login_id = :P<n>loginid(replace <n> with the page number that the region is on and use your own table name).
Don't try to run the page yet - it will give 'No data found'
Now, go back to the Page Definition screen and add two items in the region you just created - call them P<n>dob and P<n>login_id
Then, create a button in the same region (to be displayed amongst the region's items) - call it P<n>_GO and click 'Create' (take all the other defaults).
Now you can run the page, put some values into the fields and click go.
If you want to get fancier, you can change the text items to select lists etc. - let us know if you need help with that.
Hope this helps,
Bryan.

Apex 4.2 Report region sql query with "apex_item.text" renders wrongly

In APEX 4.2 page i have created region "Report data".
Type="SQl Query".
"User Interface"-->"Template"="Reports Region".
"Region Source"="select apex_item.text(1, '111') as c1 from dual".
Actually the select query is little bit more complex, but generally simplified it is such, that it uses function "select apex_item.text" to construct HTML textfield.
If i run in Sql Developer query
select apex_item.text(1, '111') as c1 from dual;Then result is:
<input type="text" name="f01" size="20" maxlength="2000" value="111" />But in APEX 4.2 the report is rendered so:
<td headers="c1">&lt ;input type=&quot ;text&quot ; name="f01" size="20" maxlength="2000" value="111" /&gt ;</td>(for this forum to display correctly i had to put extra spaces between" &gt" and ";" and so on)
And APEX 4.2 shows ugly html inside report cell/slot for me, displaying characters/symbols ">". The reason is that APEX HTML page source does not have symbol ">" but has " &gt ;" .
In APEX 3 i have similar query working well, without such anomaly.
What attribute should i change in APEX 4.2 region to display my query result as needed?
I need that function "apex_item.text", i cannot remove it.

APEX,PDF's, BI Publisher and SQL Query returning SQL code..

I don't know if I should be posting this in this Forum or the BI Publisher forum, so I am posting in BOTH forums..
I love APEX, let me say that first.. And appreciate the support offered here by the group, but am running int a confusing issue when BI Publisher tries to build a report from the above type APEX report..
Here is my dilemma:
I have a number of reports that are part of a Oracle package. They return an SQL Query back to a reports region on a page. I am having to deal with the column names returned are col01, col02..
The issue I have is, when building the Application Level query to download the XML sample from in building RTF layouts in Word, you can not use this code, you MUST use a standard SQL Select.
I have taken the sql from the function returning sql, and copied into the application query, supplying the required data values for bind variables being used in the query.
An XML file is produced, and I use this to build the RTF format file that I load back into APEX and try to use it for the PDF rendering of the report. I can view the output as a PDF in the Word add on, but when I try using it with the report, it is returning an empty PDF file.
Can anyone tell me what error log files on the bi publisher side I can look at to see what error is happening?
Thank you,

Tony,
You can find the log as follows:
- go to http://[yourserver]:[yourport]/em
- logon to OC4J EM: oc4jadmin/[yourpassword]
- click on "logs" at the bottom of the page
- in the hgrid/tree, expand OC4J->home->Application
xmlpserver
- click on view log icon
You can also observe what's going on in BI Publisher
by going to the command prompt from where you started
it.
Or, as a third option, you can locate the file on
your file system, depending on your setup, the path
would be something similar to this:
\oracle\product\10.2.0\bip\j2ee\home\application-deplo
yments\xmlpserver\application.log
With that said though, I don't expect you'll find
much in there that would help with your particular
problem. I suspect you either get no rows in your XML
at runtime, due to some session state issues, or your
XML structure does in fact not match your RTF
template.
I'm not quite following your problem description,
i.e. when did you do what and are you associating
your report layout with a report query or report
region. So just some general notes, your query needs
to be parseable at design-time, when exporting the
XML, so that you get the XML file with the proper
column names derived from your query. If you want to
use your RTF template with a standard report region,
you must export the XML file first using the advanced
XML structure option. And of course the column names
in your report query need to match the column names
in your report region.
Perhaps this helps you further diagnose what's going
on, if you have additional information that could
help, let me know. And if you could stage this on
apex.oracle.com, I'd be happy to take a look.
Regards,
MarcMarc,
Thanks for looking at this issue. Below find my remarks to your questions..
Re: your query needs
to be parseable at design-time, when exporting the
XML, so that you get the XML file with the proper
column names derived from your query.At the start of this process, the query code was a function in a package. The function was returning an SQL select statement, for a report region on a page. I took the select statement, built an application query to build a sample of the xml for BI Publisher desktop (Add-on for Word). The code was producing the usual Col01, Col02.. since at design time that is were the column names.
When I then took the xml from this and built the rtf for loading into my APEX application.
When testing the Application Query with this RTF report layout, I am getting PDF's. When using it with the report region sending an xml feed to BI Publisher I am getting nothing back.
I have since taken the sql code and moved it back into the report region, and set the region to have a type of straight SQL Query. I have even tried to hard-code the parameters I was getting from the page to limit data returned.
Is it possible to see the xml being produced by the APEX page?
Re: Stage this on apex.oracle.com.. I would love to, but we would have HIPPA issues if I posted the data on a public website.
Can I send you the RTF file and the xml file that the application query is creating to see if there something weird about them?
Thank you,

I have a number of reports that are part of a Oracle package. They return an SQL Query back to a reports region on a page. I am having to deal with the column names returned are col01, col02..
The issue I have is, when building the Application Level query to download the XML sample from in building RTF layouts in Word, you can not use this code, you MUST use a standard SQL Select.
I have taken the sql from the function returning sql, and copied into the application query, supplying the required data values for bind variables being used in the query.
An XML file is produced, and I use this to build the RTF format file that I load back into APEX and try to use it for the PDF rendering of the report. I can view the output as a PDF in the Word add on, but when I try using it with the report, it is returning an empty PDF file.
Can anyone tell me what error log files on the bi publisher side I can look at to see what error is happening?
Thank you,

Hi,
1/ first check you are passing the bind variables and
appropriate values in the call to your report - if
the query returns no data then you get an empty page
So if your query takes :P10_USERNAME variable then
pass it to the report in the URL
f?p=&APP_ID.:0:&SESSION.:PRINT_REPORT=YOUR_REP_QUERY_N
AME:::P10_USERNAME:MYUSER
2/ try to use the Default layout first to check your
report query really returns the data when called
3/ if you defined a header in your rtf template check
there is no & (ampersand) - if using & in the header
and preview the template from word it displays data
OK, but if you use this template in the report query
it fails to render the data (bug in Apex-> Bi
Publisher integration maybe?)
4/ If using the table in the rtf template check its
width does not overflow the page margins - there is a
problem with pdf export
5/ check
/oc4j/j2ee/home/application-deployments/xmlpserver/app
lication.log forthe information on BI Publisher runs
RadoIssue was in the APEX page having issues.. I recoded a new page and am able to generate BI Publisher based PDF files..
Thank you,

Hi anbarasan,
Maybe you can create a report of type "SQL query (PL/SQL Function returning query". Then in the region source, something like:
DECLARE
v_sql VARCHAR2 (4000);
BEGIN
v_sql := :PX_YOUR_ITEM;
RETURN v_sql;
END;

Newbie - help with a SQL query for a bar chart - Originally posted in APEX

I originally posted this in the APEX forum but someone there suggested this is more of a SQL question. Anyone out there who can provide some assistance?
Hi,
I'm a new user on APEX with no real SQL knowledge and I'm trying to build a dashboard with charts into an existing APEX application. Based on another application, I have come up with the following SQL code:
select null link
, CATEGORY label
, count (decode(PROJECT_STATUS,'1',PROJECT_ID))"Active"
, count (decode(PROJECT_STATUS,'2',PROJECT_ID))"Complete"
, count (decode(PROJECT_STATUS,'3',PROJECT_ID))"On Hold"
, count (decode(PROJECT_STATUS,'4',PROJECT_ID))"Pipeline"
, count (decode(PROJECT_STATUS,'5',PROJECT_ID))"Pending Review"
from GRAPO_PROHEADTRK
where (PROJECT_STATUS='1' or PROJECT_STATUS='2' or PROJECT_STATUS='3' or PROJECT_STATUS='4' or PROJECT_STATUS='5' or PROJECT_STATUS='6')
group by CATEGORY
Order by COUNT(PROJECT_ID) DESC
The code from the other app was:
select null link
, FUNCTIONAL_AREA label
, count (decode(PROJECT_STATUS,'Active',PROJECT_ID))"Active"
, count (decode(PROJECT_STATUS,'Complete',PROJECT_ID))"Complete"
, count (decode(PROJECT_STATUS,'On Hold',PROJECT_ID)) "On Hold"
, count (decode(PROJECT_STATUS,'Recurring',PROJECT_ID))"Recurring"
, count (decode(PROJECT_STATUS,'Pipeline',PROJECT_ID))"Pipeline"
, count (decode(PROJECT_STATUS,'Not Approved',PROJECT_ID))"Not Approved"
from PM_V2
where LOB='S2S' and (FUNCTIONAL_AREA='Accounts Payable' or FUNCTIONAL_AREA='Expense' or FUNCTIONAL_AREA='Procurement' or FUNCTIONAL_AREA='Fixed Assets')
group by FUNCTIONAL_AREA
Order by COUNT(PROJECT_ID) DESC
I'm getting a "Failed to parse SQL query!" error when I try to run validation.
Is this enough info for some assistance? Any help would really be appreciated.
Thanks,
Rachel

group by CATEGORY
Order by COUNT(PROJECT_ID) DESCIs there a problem with the code above?
It's curious that the WHERE clause includes "PROJECT_STATUS='6'", but there is no pivoted column for project_status='6', like there is for '1' through '5'. That's not necessarily a mistake, and it wouldn't raise an error in any case.
Instead of
where (PROJECT_STATUS='1' or PROJECT_STATUS='2' or PROJECT_STATUS='3' or PROJECT_STATUS='4' or PROJECT_STATUS='5' or PROJECT_STATUS='6')you could say
where PROJECT_STATUS IN ('1', '2', '3', '4', '5', '6')but that probably has nothing to do with your current problem.

I'm getting a "Failed to parse SQL query!" error when I try to run validation.Is that an Apex error message? Sorry, I don't know anything about Apex.
If you can't get a more specific error message from Apex, then try debugging this statement in SQL*Plus. When you get it fixed, then you can copy it back into Apex.
If this is a SQL problem, then you should be able to re-create the problem in pure SQL.
If you can't re-create the problem in pure SQL, then it's probably an Apex problem, and belongs in the Apex forum, not here.
I don't see anything obviously wrong with your code, but I can't tell if, for example, you spelled a column name wrong, or if something has the wrong data type
Is this enough info for some assistance? Any help would really be appreciated.It wiould be better if you posted a completE script that people could run to re-create the problem, and to test their ideas.
Whenever you have a problem, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables involved.
Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.
Always say which version of Oracle (and any other software, such as Apex) you're using.

APEX 4.1, SQL Query(Updateable report), Validation issue.

Hi,
I am using APEX 4.1.
I have SQL Query(Updateable report), we have created validation for the columns in this report.
The validations are working properly only for the first row of the report on submitting, the remaining rows are not getting validated.
If we check mark the rows it will get validated, but we want the validation to happen without checkmarking, on all the rows on clicking submit button.
Can someone help me to fix this issue?
Thanks in advance.
Thanks & regards,
Ravi.

Hi Ravi,
Welcome to Oracle Forums!
Please acquaint yourself with the FAQ and forum etiquette if you haven't already done so.
Always state
<ul>
<li>Apex Version</li>
<li>DB Version and edition</li>
<li>Web server used.I.e. EPG, OHS, ApexListner Standalone or with J2EE container</li>
<li>When asking about forms always state tabular form if it is a tabular form</li>
<li>When asking about reports always state Classic / IR</li>
<li>Always post code snippets enclosed in a pair of {code} tags as explained in FAQ</li>
</ul>

APEX validations in updateable reports built on a PL/SQL query

Sorry if the question is not clear (english is not my mother language) or if the answer already exists on the forum (I have not been able to find it).
I build a report on a PL/SQL function query.
In this PL/SQL query i use apex_item.checkboxes or texts to let the end user change/enter some new data.
As i need to do some validations on the user entries, i have already used some events (e.g. onChange) that trigger
simple javascript validations checking if data is numeric or length of data entered....
But i would like to use also the standard validations of APEX to make some more complex validations (e.g. checking coherency) on
many data entered by the end user.
I am trying to build a PL/SQL to loop through the report lines through a checkbox item i have added
but the process of debugging is awfull for me.
- Is there a pointer to a code example of validations within a query report that would help me in achieving this validation
- or could someone give me some clue on how to acess these report data in the interface.
Thanks in advance,
Daniel

Daniel:
You can check out Denes Kubicek's APEX demo site for ideas on how to create validations for a tabular form.
