Populating item using a sql query based on other item of diff table

Hi,
It would be great if someone could help.
I have two items on my form page .
My first item P1_sub_prog is of select list with submit, it fetches values from table prog "mv_cap_prog_subprog" of the same schema whihc I am using for teh current application.
I want my second item P1_PROGRAM to be populated with value corresponding to my first item value, after being fetched from the same table on the basis of the first item value (P1_SUB_PROG)
Both the item values have a relation.
I tried by creating sql as well as LOV for the second item but its not working.
It displays nulll in the second item field.
While using sql I tried the following query
in the source request of second item i.e P1_PROGRAM
SELECT DISTINCT a.program_id d,a.program_id r FROM
mv_cap_prog_subprog
WHERE SUB_PROGRAM_ID = :P1_sub_prog

Hi,
Search this forum for "cascading select list".
You will find lots of help.
Cheers,
Patrick

Include Button that executes PL/SQL procedure to SQL query based region

I would like to add two columns to a SQL query region.
These columns would not be sourced from the query, but rather would be used to execute a PL/SQL procedure.
For example, I would like to have a manager approve or deny adding an additional employee to the department.
There would be one button for APPROVE. And, one button for DENY.
The PL/SQL procedure would execute to perform the required DML based upon the selected action (either APPROVE or DENY).
A sample output would look like this:
<APPROVE>, <DENY>, John Doe, Accountant
<APPROVE>, <DENY>, Jane Doe, Accountant
Is there any way to add a button to a SQL Query based report region where that button executes a stored proc? If so, what is the basic process for doing this?
Thanks!

Using a SQL Query in an Alert and Matching a String

I've created an alert in 12.0.4 using a SQL Query and the field that I'm trying to match is a string. Originally the query returned multiple rows but when the alert still didn't fire, I modified the query WHERE clause to return only one row:
NAME RESPONSE
Are area lights working? No
My expression in the metric is RESPONSE. In the Monitor I'm matching a string equal to No. (Do I need double quotes around the matchvalue? Single quotes? No quotes?) The metric is in the 15min scan group, the role is xMII Developers and I'm in that role. The monitor alert string is ' = '. Both metric and monitor are active and I've subscribed to the monitor. Other alerts in the 15min scan group (all based on tag queries) are firing off properly.
Why is nothing showing up in the Alert Log?

SQL Query based BI Pub report - Taking too long to produce the output

Hi All,
I was trying to produce a BI Publisher based report through enterprise edition of BI Publisher 10.1.3.4
Its a sql query based report and it has around 20 columns and it has around 1 lakh records.
The query actually takes only 2 seconds to execute in the database but when we execute from BI Publisher it takes a long time and also it times out most of the time
Is there something I am missing in the configuration options ?
Thanks
Shasi

I am facing the same problem as well. I am using the Publisher Web service API to run a report with 1 Million records. This report is configured to use OBIEE. It takes a lot of time to generate the report ( around 30 Mins) and even though OBIEE generates the data, my web service client either timesout. Even after increasing the timeout, a 500 internal server error is thrown . Does anyone know of a solution to this.
Thanks

How to set the value of application item using pl/sql in application process

Hi guys,
I want a global variable (application item) whose value will be set at the start when a user logs in to the application. The value will be retrieved from database using a sql query. I do not know the exact syntax to set the value of application item in application process. Also i want to know in which type of application process should i use to set the value of application item when a user starts a session. The value of application item varies from user to user.
Please help.
I am using apex 4.2
Regards,
Waqas

You can use the application item as bind-variable with its name. ie. your application item is named G_MY_APPLICATION_ITEM, then you can access/set it using :G_MY_APPLICATION_ITEM.
For example
BEGIN
    -- assign like a variable
    :G_MY_APPLICATION_ITEM := 'LARRY';
    -- use in a SQL statement
    SELECT WHATEVER_COLUMN
      INTO :G_MY_APPLICATION_ITEM
      FROM MY_TABLE
     WHERE USERNAME = :APP_USER
END;

Aren't these rules equivalent to "Monday this week, where Monday is the first day of the week"? In which case the PL/SQL Expression you require is:
trunc(sysdate, 'iw')For example:

3 select

5 , trunc(d, 'iw') monday

How to use this sql query in oracle?

Hi all,
i am using one sql query that is
SELECT @ToDate = '2012-10-03 00:00:00.000'
select @BetweenDate = DATEADD(MM,-1,@ToDate)
select @FromDate = DATEADD(m,DATEDIFF(m,0,@BetweenDate),0)
SELECT @ToDate = DATEADD(month, ((YEAR(@BetweenDate) - 1900) * 12) + MONTH(@BetweenDate), -1)
so @todate value is = '2012-10-03 00:00:00.000'
so in @betweendate value will come 1 month before like '2012-09-03 00:00:00.000'
again in @fromdate value will come like that '2012-09-01 00:00:00.000' means first date of @betweendate
and again @todate value will come like that '2012-09-30 00:00:00.000' means last date of @betweendate
it's happening in sql and i have to use same logic in oracle also.
how to use it??
thanks

declare
todate date:= to_date('2012-10-03 00:00:00','yyyy-mm-dd hh:mi:ss');
betwendate date := add_months(todate,-1);
for datediff / additions you can direct subtract/add two different date variables
like
datediff = betweendate -todate
dateadd := todate+1;

I want to use the SQL query IF EXIST to update or insert data in a ms access table, but it doesn´t work

Hi,
I want to use the SQL query IF EXIST to update or insert data in a ms access table, but it doesn´t work
(fault number -2147217900)
I want to search for a value in a ms access table , if it exist i want to update it, if not i want to insert a new row.
Working with LabView 7.1, database con. toolset.
Who can HELP?
Thanks a lot
Marco

Hello,
I think that If exist is not a standar SQL command (I know it exists I think in Oracle and SQL server), MS access doesn't support it, so I think the best way to do it is first make a Select and then either an Update or an insert, sorry...

Using multiple sql query

Im writing a jsp that pulls data from the database and loads it into dropdown-list looks like this:
<select name="Source">
<%
conn = DriverManager.getConnection(url, username, password);
Statement stmt = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_READ_ONLY);
ResultSet rs = stmt.executeQuery("SELECT BBCourseID(Sroffer.SrofferID)course_name, SrofferSchedule_Faculty.FacultyID AS FacultyID FROM SrofferSchedule_Faculty srofs JOIN SrofferScheduleID sros ON srofs.SrofferScheduleID= sro.SrofferScheduleID JOIN Sroffer sro ON sro.SrofferID= sros.SrofferID WHERE srofs.FacultyID=IDnumber");
rs.beforeFirst();
while (rs.next()) {%>
<option value="<%=courseid=rs.getString("BBCourseID")%>"><%=courseid%> <%=rs.getString("course_name")%></option>
<%}
%>
</select>
Problem is, I have to pull the FacultyID from cams using this sql query
("SELECT FacultyID FROM FacultyPortal WHERE PortalAlias="") berfore i can run the query above. Don't know how to do this in a jsp
Edited by: JohnsonJ on Mar 26, 2009 5:53 PM

You know how to get a connection and how to execute a query and how to process the resultset - so what's standing in your way of doing that for the faculty ID?
Isn't there a join you can do to get that in one query?
And finally - you really shouldn't do this in a JSP, use a servlet to package the result up in some Java Collection and process it with JSTL tags.

Can we implement the custom sql query in CR for joining the two tables

Hi All,
Is there anyway to implement the custom sql query in CR for joining the two tables?
My requirement here is I need to write sql logics for joining the two tables...
Thanks,
Gana

In the Database Expert, expand the Create New Connection folder and browse the subfolders to locate your data source.
Log on to your data source if necessary.
Under your data source, double-click the Add Command node.
In the Add Command to Report dialog box, enter an appropriate query/command for the data source you have opened.
For example:
SELECT
 Customer.`Customer ID`,
 Customer.`Customer Name`,
 Customer.`Last Year's Sales`,
 Customer.`Region`,
 Customer.`Country`,
 Orders.`Order Amount`,
 Orders.`Customer ID`,
 Orders.`Order Date`
FROM
 Customer Customer INNER JOIN Orders Orders ON
 Customer.`Customer ID` = Orders.`Customer ID`
WHERE
 (Customer.`Country` = 'USA' OR
 Customer.`Country` = 'Canada') AND
 Customer.`Last Year's Sales` < 10000.
ORDER BY
 Customer.`Country` ASC,
 Customer.`Region` ASC
Note: The use of double or single quotes (and other SQL syntax) is determined by the database driver used by your report. You must, however, manually add the quotes and other elements of the syntax as you create the command.
Optionally, you can create a parameter for your command by clicking Create and entering information in the Command Parameter dialog box.
For more information about creating parameters, see To create a parameter for a command object.
Click OK.
You are returned to the Report Designer. In the Field Explorer, under Database Fields, a Command table appears listing the database fields you specified.
Note:
To construct the virtual table from your Command, the command must be executed once. If the command has parameters, you will be prompted to enter values for each one.
By default, your command is called Command. You can change its alias by selecting it and pressing F2.

Setting current values in Multiple Select List in SQL Query based Report

Hi,
I have a report based on a sql query that contains a multiple select list. Unfortunately I cannot get the multiple select list to display the current values (p_value) correctly. I have created a page item, :p311_current_versions, that is set using a pre-header process and it returns a value with a colon delimited format e.g. '10.1.2.1.0:10.1.2.2.0'. Then this item is used in the sql query to set the current value (p_value) of the apex_item.select_list_from_query function. However when the table is displayed, instead of having two entries, 10.1.2.1.0 and 10.1.2.2.0 selected, it has an extra entry '10.1.2.1.0:10.1.2.2.0' selected.
Here is my code:
select distinct a.product, a.version from (
select distinct
apex_item.display_and_save(2,product)||apex_item.hidden(1,env_product_id) PRODUCT,
APEX_ITEM.SELECT_LIST_FROM_QUERY(3,decode(product, 'HTTP Server' , :p311_current_versions, version), 'SELECT distinct version d, version r FROM ebs_tech_stack where
product ='''||PRODUCT||'''',
decode(PRODUCT, 'HTTP Server' ,'multiple="multiple" style="width:170px"','style="width:170px"'),
'NO') as version
from ebs_environment_tech_stack
where environment_id = :p311_umgebung_id) a order by a.product
If anyone can help me figure out how to set the current values correctly I'd be really grateful!!
Thanks in advance,
Jean

Jean,
I don't think this is possible using the apex_item package. The select_list_from_query function accepts only a single value for the second parameter.

Executing SQL-query based on user input in text-box on APEX page

I'm new to developing in APEX, and I encountered a problem...
Is it even possible to make such thing: use text area for input of some SQL-query and then execute it on my schema and show results in report item? And if the answer is yes, can somebody provide me tips on how to do that?
Thanks in advance.
