Error with Report Page in Oracle Application Express - oracle

I have a report based on a SQL Query, the report has 3 columns from v$session.
select distinct to_char(SQL_EXEC_START, 'DD/MM/YYYY HH24:MI') TIME_STARTED, module REPORT_NAME, action CURRENT_STEP from v$session where module like '%BOB%'
In SQL Developer, the query brings up what you would expect. However in the APEX report page, no matter what is in v$session, I always get (in addition) the following displayed at the top of the report page, in the actual report columns:
<DATE> Processes - point: BEFORE_BOX_BODY BOB01/APEX:APP 104:7
Can anyone tell me how to get rid of it, and simply output the query results into the report page, and nothing else?

It seems that it displays current report as well. So - remove it, e.g.
select distinct
to_char(SQL_EXEC_START, 'DD/MM/YYYY HH24:MI') TIME_STARTED,
module REPORT_NAME,
action CURRENT_STEP
from v$session
where module like '%BOB%'
-- add this
and module not like '%104:7%'
and current_step not like '%BEFORE_BOX_BODY%'

Error with a user defined report in Oracel SQL Developer - Missing IN or OUT parameter at index:: 1

I have created a user defined report within Oracle SQL Developer, with a bind variable.
The report consists of a master_report (style is table), child_report_a containing with a style of 'table' and child_report_b which is the same query, but with the style of 'script'.
I am able to select a cell/row of my master report, and child_report_a data changes accordingly (ie, it returns the cells of the same date I selected.
However, when I try to view this in child_report_b (With the 'script' style) it errors with "Missing IN or OUT parameter at index:: 1".
So the setup is:
tablea
id_pk (number)
name_pk (varchar2)
1
Jack
2
John
3
Amy
tableb
id_fk (number)
start_time(timestamp(6))
1
01-JAN-23 12.00.00.123000000
2
01-JAN-23 13.00.00.123000000
3
02-JAN-23 14.05.00.123000000
User Defined Report:
master_report (Style=Table):
SELECT * FROM tablea
child_report_a (Style=Table) & child_report_b (Style=Script):
SELECT * FROM tablea a INNER JOIN tableb b ON b.id_fk = a.id_pk WHERE trunc(start_time) = trunc(to_timestamp(:STARTTIME)
Any help is appreciated.
EDIT: Included better example of setup.
My goal is to be able to select a row from the master_report, and the child_report_b would return all results which match the date (as currently happens in child_report_a) in the script format.
Welcome to StackOverflow!
The reporting feature is one of my favorites in SQL Developer, so I will try to get you started.
We can't technically answer your question without a fair bit of guessing. We know what's happening on one side of the JOIN, you have a timestamp that you're using TRUNC on.
But we can't tell what is on the other side of the equality predicate in your JOIN.
Here's a working example, see if this helps you.
Parent Query
select trunc(systimestamp) A
from dual
Child Query
select object_name, object_type, last_ddl_time
from user_objects where :A > (trunc(systimestamp) - 30)
And the report -
To debug your report, substitute the bind :STARTTIME with a literal value that is equivalent to what your parent query would return. If that works, so should your report.

SELECT statement in SQL DEVELOPER

So I am new in SQL DEVELOPER tools and I have written a simple select statement like:
SELECT * FROM employee;
it worked fine but there was a yellow warning mark underneath SELECT and I clicked on that and my query changes into the following query:
SELECT "A1"."EMPLOYEE_ID" "EMPLOYEE_ID","A1"."FIRST_NAME" "FIRST_NAME","A1"."LAST_NAME" "LAST_NAME","A1"."SALARY" "SALARY", "A1"."DEPARTMENT_ID" "DEPARTMENT_ID","A1"."MANAGER_ID" "MANAGER_ID","A1"."HIRE_DATE" "HIRE_DATE"
FROM "INTRO_USER"."EMPLOYEE" "A1";
My Quest is what is the difference between these two queries? although their output is the same
The glob * has been expanded to all column of the table. The table name EMPLOYEE is aliased to A1 to make it shorter.
The feature you are seeing is called 'SQL Text Expansion,' and it's setup to allow you to see what your query would look like if you were working with one or more VIEWS.
For example, SELECT * FROM ALL_TABLES is quite complicated. This feature allows you to see what's actually involved when running that SQL.

There is probably no change or expected delta in the performance or execution plan of the 2 versions of your query.

How to have sysdate result remoted across database link?

I'm running a query across a database link to a Sybase server from Oracle.
In it's where clause is a restriction on date, and I want it tied to sysdate, so something like this:
select * from some_remote_view where some_numeric_key = 1 and
some_date > sysdate+2
The problem is, when I do explain plan, only the condition some_numeric_key = 1 shows up in the actual sql that is getting remoted to the sybase server. Oracle is expecting to perform the date filter on its side.
This is causing a performance nightmare - I need that date filter remoted across to have this query working quickly
Even if I try something like casting the sysdate to a charcater string like this:
to_char(sysdate-2,'YYYY-MM-DD')
It still does not remote it.
Is there anything I can do to get Oracle to remote this date filter across the db link to Sybase?
Doing integration between Oracle and other platforms I often run into this problem, not just with SYSDATE but with other non-standard functions as well.
There are two methods to work around the issue, the first being the most reliable in my experience.
First, you can create a view on the remote db with the filters you need, then on the Oracle side you just select from the new view without additional filters.
Second, if you are not allowed to create objects on the remote side, try using bind variables (of the correct data type!) in your Oracle SELECT statement, e.g.:
declare
v_some_date constant date := sysdate + 2;
begin
insert into oracle_table (...)
select ...
from remote_table#db_link t
where t.some_numeric_key = 1
and t.some_date > v_some_date;
commit;
end;

Creating Easy Way to update variables in large code

I am using Oracle SQL Developer and have a rather large query built. The query is going to be run on a monthly or quarterly basis. I was wondering if there was a way that I can do a declare statment up top and then in the code just reference these variables created. That way when someone wants to run the query they can just change the dates at the top of the code rather then have to dig through all of it. I am kind of new to Oracle SQL Developer but I know in other sql codes I built I could simply declare the variable and then set it and then in the code call the variable name. Below is an example of what I know how to do but i am having trouble in Oracle SQL Developer.
Example: I have a data base that contains the columns Business, business type(small,medium,large) number of deposits, deposit amount and deposit date. I want to build a query that outputs a quarterly summary of the number of deposits and the deposit amount and be able to change the quarter and size of the business.
Example Code from my previous SQL expereince this is an example of what I am trying to do since i can not disclose my code with the table names etc in them.
Declare #busstype,#qbegindate,#qenddate
Set #busstype = 'small'
Set #qbegindate = '01-JAN-2013'
Set #qenddate = '01-MAR-2013'
Select business,numberofdeposits,depositamount
From business_transactions
Where ('#qbegindate'<=depositdate<='#qenddate'
And businesstype = '#busstype')
Group By Business
The results would list out the businesses name and then the total deposits and total amount.
I know this code is not right but its just an example of what I am looking to do in Oracle SQL Developer. The query I have built is working fine I just find it a pain to dig through the code to change dates and criteria and was wondering how I would do something like this since i have figured out that I am not able to do this in ORACLE Sql Developer.
Here is an example with predefined variable:
set feedback off
var abc varchar2
begin
:abc := 'abc';
end;
/
select :abc as a from dual;
Output:
A
--------------------------------
abc
Common table expressions allow variables to be defined at the top of the query. For performance and style reasons this is generally not a good way to
use common table expressions. The advantage is this query can be run in any IDE and it is completely self-contained.
--Variables - change these before running.
with busstype as (select 'small' value from dual),
qbegindate as (select date '2013-01-01' value from dual),
qenddate as (select date '2013-03-01' value from dual)
--Query - do not modify code below.
select business,numberofdeposits,depositamount
from business_transactions
where depostiddate between
(select value from qbegindate)
and
(select value from qenddate)
and businesstype = (select value from busstype)
group by business, numberofdeposits,depositamount;

SQL Developer get time when query is run

I am using sql developer to fire some queries. I want to know the time when query has run. I see that when you fire sql query, you can see "Task completed in x seconds". But here I want to see the time when query got execute. Is there a way like showtimestamp or something?
Add select to_char(sysdate, 'YYYY-MM-DD HH24:MI:SS') from dual; if the scripts can be modified.
If that's not an option then right-click on the Worksheet and select SQL History:
