Application Express :: Pull The Next Value From Query?
Oct 9, 2013
I am having trouble trying to pull the next value from a query based on a where clauseThe query I am using is:
Declare nextID NUMBER(22);BEGINselect lag(ref_contact_id, 1,0) OVER (ORDER BY ref_contact_id)into nextID from (select ref_contact_id,lead(ref_contact_id, 1,0) OVER (order BY ref_contact_id) as "NextNbr", lag(ref_contact_id, 1,0) OVER (order BY ref_contact_id) as "LastNbr"from (select rc.ref_contact_id from REF_CONTACT rc order by FIRST_NAME ))where ref_contact_id = 793 ;END; The returned value is 0.
I understand why but not how to pull the next value base on a particular ref_contact_id.
In the database we use for transfer articulation, there are numerous tables delivered with the product. The institution decided not to use certain fields, and all instances of those fields have no data. In other words, there might be a field in the table called INSTCD, but no records in the table have ever inserted any data into that particular field. In the table there are thousands of records, and we don't necessarily know which of the fields have never been used (no list has been retained and no one who initially was involved in the decisions is available to ask), as there are multiple fields in each table. How can I write a query that pulls only the fields in the table that contain data. In the example below, the SHRTRIT table contains a field called ACTIVITY_DATE, but there is no data in any record in that particular field, so I don't want it to show up on the output. In this particular case, I KNOW not to pull this field in a SELECT, but in a case where there might be 130,000 records and I DON'T know if a field has records in it, how could I do that?
if the question I'm asking doesn't make sense and I'll attempt to word it better.
I am to trying to fetch session id of a previously submitted process of a search button......so that i can display the search results in a different page.....so is there any sql query or pl/sql procedure to fetch the session id.
I am using its value in a query by using sql collection array. My requirement is that I need to hide that shuttle. But when I hide the shuttle, its value is not retrived by the query.
There is simple IRR "Select * from emp" on my page.End user put some filters on the report from Actions Menu. Can i somehow (on any button click, etc) get the new SQL which is saved by user now?
The SQL Query portion of Authorization Schemes are deleted or set to NULL after editing. Re-entering the SQL Query will not save the SQL, so the SQL Query is lost.
I had to update WWV_FLOW_SECURITY_SCHEMES.ATTRIBUTE_01 via sql to restore and modify the SQL Query portion of the Authorization Schemes.
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. 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.
how can i define the following condition in query definitions tab to define query condition for the value which is linked from previous tab/report ,:P2_SR_ BUSINESS_UNIT is the Item which are getting value from another report Value.
BUSINESS_UNIT=DECODE(:P2_SR_BUSINESS_UNIT,'BS&I','Business Sales And Information','WS','Whole Sale')

I have stacked into something: if there is a way to define a single row form page based on table in which I could query and update without using a tabular page (to call the single row form). I want only to use only one page. Does APEX has this functionality?
steps to achieve this report I need a Date Column on top of the page Depending on the selected date, Result should be displayed below for e.g.
suppose i select a date as 14-aug-2013
Enter Report Date ___________________ ( Date Picker) Location Name Report Date Quantity valueXYS 14/08/2013 5000 1200000ABCD 14/08/2013 2000 24000-------------------------------------------------------------------------------------------------TOTAL 7000 1224000
1.-) i got a page that contains 2 regions, lets say :master (HTML text) and a detail (tabular form updateable report) in my tabular form i got a hidden item that should take the value from the master form. how do i do this ?
2.-) i am calling a form from another form, sending a couple of fields as a link parameters. the second form is called as expected, but i need that records on the second form that match the parameters get displayed. how do i achieve that ?
BEGIN IF UPPER(:P23_SERVICE_TYPE) like 'GUIDE%' THEN SELECT NAME D, CODE R FROM SPECIAL_SERV_MAS WHERE NVL(ACTIVE_FLG,'N') = 'Y' AND NVL(GUIDE_FLAG,'N') = 'Y' and CITY_CODE LIKE NVL (:P23_CITY_CODE, '%')

When i put this code in my LOV Select list Section then display me Error

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).
I am having a problem with a popup lov. When I click on the "popup icon" I can select a supplier and it is stored in the field. But when I leave the form and return later, it shows the return value instead of the display value. For example: you select "supplier A" from the popup list with ID 12. "Supplier A" is shown in the text field, when you save the form, it stores ID 12 in it. But when you return to the form, it fetches ID 12 and shows "12" in the text field instead of "Supplier A".
I tried setting the "source" of the popup lov field as an SQL query, but that didn't work for me.
I am trying to create a tabular form based on a SQL query, that has a query-based select list with a where clause that references a column in the originating SQL query.
The situation is, I have a table that stores client_id, source_id and build_id, lets call it client_source. I have a second table, build_source, that contains source_id and build_id, with a one to many relationship between the two (source_id of 1 could have build_id of 1-7).
Using a tabular form, I want to select the corresponding build_id to be used in client_source, but the select list must only contain the build_id's for that rows particular source_id.
Here is an example of the SQL source of my tabular form;
select s.ROWID, s.CLIENT_ID, s.SOURCE_ID, APEX_ITEM.SELECT_LIST_FROM_QUERY(1, s.BUILD_ID, 'select b.build_id display, b.build_id return from build_source b where b.source_id = s.SOURCE_ID ') lst from client_source s
... what I am trying to achieve is that the source_id fields in bold match. When the query is built this way I get an 'invalid identifier' Oracle error on s.SOURCE_ID at runtime.
Is there some special tags that need to be used to reference the outside column?I am running on Application Express 4.1.0.00.32, on a Oracle 10g release 10.2.0.4.0 database.
POSTCODE_TO_LAT_LNG_GM_API(postcode IN VARCHAR2, lat OUT NUMBER, p_long OUT NUMBER)
to convert a postcode into lat/long values. I then need to add them to the returned SQL statement so I used the string concat operator || with to_char but it comes up with this error when I try to apply the changes: Query cannot be parsed within the Builder. If you believe your query is syntactically correct, check the ''generic column'' checkbox below the region source to proceed without parsing.
ORA-00936: missing expressionh4.
h4. btw I'm using Oracle 11g release 11.2.0.3.0 and Apex version 4.1.1.00.23
a tabular form with two "select list (query based LOV)" fields. The first one must affect elements in the second one. And so the second query based LOV field should has a "where attr1 = first_list_selected_value" in the query.
I have developed a report using apex shared components (report query and report layout) along with BI Publisher for report printing in pdf format. the Report template is built using Template Builder for Word. I have configured my Apex4.1 env with BI Publisher 11. This report is working fine for hardecode ID ( like REQUEST_ID=10 ). to make report dynamic i have made following additions in the report
I have added where clause in report query as WHERE REQUEST_ID = :REQUEST_ID (:REQUEST_ID is the text field in my page).
Added a text field names :REQUEST_ID to get user input at run time.
Create a button and add Repot Query URL in its properties. When i run the report with some valid value in :REQUEST_ID text field i did not get expected result infect there is no record getting displayed in the PDF file. i think this is not the write way to do this but interestingly im not getting any error. how can i get this functionality in apex this way or the other ?
I am on APEX 4.1.1, db 11g and I have a report which is quite slow to retrieve results from its query. The page has some filter fields (e.g. store code, dept code) in addition to the generic search field.
When the user lands on this page (from a menu page), the query runs before the page displays and this typically takes 1-2 mins without any filters yet set. The usual browser loading indicators are not obvious to the user and they might not be aware that it is working on the request.
I want it so that it will only run the query AFTER allowing the user to get to the page, let the user fill in some filter criteria and then click on the GO button. Therefore the query will run after the page is submitted. When you hit the GO button on the interactive report, a nice rotating apex_loader.gif appears, making it obvious to the user that it is working on the request.
I would prefer NOT to create 2 pages, one for user filter, and a second for the actual report as I have many reports/inquiries which fit this category and I would prefer NOT to have to create pairs of pages for each.
I created a "Select List" in the Shared Components area as follows:
My goal is to create a shared select list that can be used on any form for a particular Field.
IF :P10_FK_RSTA_CODE is NULL THEN RETURN 'select col_description, col_code_pk from CODE_TABLE where col_active_ind = ''Y'''; [code].....
Which works great, but how can I make the select list work for the same column on a different form? Because :P10_FK_RSTA_CODE is hard-coded in the function, I can't reuse this Function from a different form. (I could rename the Field on every form to the same name, but I'm hoping there is a better way.)
Is there a way I can pass in a variable from the Field Item to make this dynamic where I can use it on any form?
I have a query that selects multiple series for a bar chart (I have defined only one chart series, and have 3 columns selected to represent 3 series). The series display on Bar Chart is fine. Now I want to create a separate link target depending on which series is clicked on the chart. I am not able to do this.
We are using Oracle 11g with Apex 3.2 on AIX. We are reporting data from customer satisfaction surveys. I'm using the following sql to create my report
<code>select * from( select month,'Overall Satisfaction' as q_group, 1 as srt,Overall Satisfaction,site, case when count(*) < 31 then '*' else round((sum(ttos)/count(*))*100,0)||'/'|round((sum(bfos)/count(*))*100,0)||'/'||count(*) end ospct from v_XXX_report a,(select distinct month_dt month from v_XXX_report) b where Overall_Satisfaction is not null and year_dt = 2012
[Code]....
The problem is that site is not allways present and sometimes I have other variables in addition to site. This creates a situation where the month columns will not allways appear at the same column number. For example, When I run this query as is then the "JAN" column is Col3 (first column is a break, col2 is not shown). When I run this query without site then "JAN" is the second column. I would like to create column links for the "JAN" - "DEC" columns but not for any other columns.
Another issue - in the column link creation screen I can create up to 3 variables that I can pass to the next page. Since my query is a pivot I'm uncertain how to pass the column heading or the row value (for col2)
ie Overall Satisfaction JAN FEB MAR APR MAY ... Overall Satisfaction 12/12/200 12/12/210 12/12/220 12/12/230 12/12/240... Recommend 12/12/200 12/12/210 12/12/220 12/12/230 12/12/240... etc.
So if I clicked on the values at Recommend:FEB how can I get "Recommend" and "FEB" into variables that I can use on the next page? I've tried #column_name#, #month#, #q_name# and #APEX_APPLICATION.G_F10# but no luck.
I want to start by saying I am brand new to SQL. I have an access database linked to my oracle and am trying to query a very specific set of data and I can't seem to narroe it down. I have 244,000 lines in the DB and I'm trying to find items on a specific trype of vendor agreement. I may have the same item on multiple agreements. ex 1-, 1a-, 2-,2a-,3-,3a-,4-,4a-,5-,5a-,6-,6a-,7-,7a-,8-,8a-.
I need to find a way to select just items that appear on a 4- or 4a- and no other agreement reference. The query I did so far pulls all of the 4- and 4a- agreements but will also pull items,like #233 in the example above, but not showing the 1a- agreement. I need it to overlook that item eventhough it does appear on the agreement I am looking for but also has an agreement I am not. the statement I am using right now is:
SELECT item, ven_item, ven_agrmt_ref, base_cost, vendor FROM "all items by agreement" WHERE ven_agrmt_ref >= '4' ORDER BY item
I want to move data between two instances and recommended we create a local database link to PULL data from remote database located here (supplier on site) but they want to PUSH data to us. I thought you could only PULL data over a database link but then read the link [URL] where PUSH is considered ? I was going to use standard creatas like create table A as select * from table A@<remote_db_link> which works well and fast ( tried and tested) but some are saying they think PUSH quicker/better ?
we do have data "PUSH" already but this does not use a db link - effectively it calls a local proceedure here and passes a row of data and is slow ie for a 1000 row table to be pushed to us we have our local proceedure called 1000 times.
I have always suggested a PULL with db_link as the fastest method - any proof OR info on a fast PUSH method ( that is quicker than PULL ) ? can you REALLY push ?
