Multi-Row Delete from a table via a button without submitting the page

Hi,
I have a simple page based on a (temporary) table. There is a submit button that calls a PL/SQL process. However, I would like to have an 'Abort' button that deletes all rows from the table belonging to a specific user.
I had a look at 'Processes -> Data Manipulation --> Multi Row Delete' but this can only be linked to a page level event such as onSubmit. My onSubmit is linked to another process so this is not an option for me.
I thought of creating a PL/SQL function for the deletion and calling it from Javascript linked to a button. I have done the PL/SQL and the button but don't know how to call PL/SQL from JS. And is this the correct way of doing something like a deletion? Any documents that show how can this be done will be much appreciated....
I had a look at the forum and the documentation but could not find anything for multil-row deletion triggered from a button.
Your help is appreciated as I'm a newbie :-)
Thanks
Angela

Hi,
I actually found the solution. I created a button (that submits) and a computation that calls the PL/SQL function conditional on that button being pressed. Initially I got confused because I already had another PL/SQL function attached to different button. I didn't think that having two buttons that submit the page and call different functions was possible.
Thanks
Angela

Multi row checking in advance table and passing this to other OAF page...

Hello,
I have an advance table on my OAF custom page, this table have checkbox column. I need to implement the solution when user selects some rows in this table and then press submit button on the page. So new OAF page is opened and on that page i need to show those lines which user selected in previous step.
The problem is that right now i have this selection checkbox tight to VO attribute which updates table and then on submit do commit and on another page i'm just selecting rows which have this flag set. But what i'm looking for is - do not make commit and changes on database data, but pass the selected rows as kind of parameter to other page or something like this.
Could you please give me any suggestions of how is the better way to implement this solution?
thanks in advance...

Make a transient VO, and insert all the lines the user has checked.Share the same AM in other page and while redirecting retain AM. On this page show the lines from the transient VO.Another option could be utilizing session.

Tabular form - Multi row delete error

Apex 4.0.2
We have a simple CRUD type of application on a bunch of tables built using Apex v1.6 that has, over the years, been upgraded to v4.0.2 and it is working mostly fine. It uses all out-of-the-box standard components, forms, classic reports, nothing too fancy. Recently one of the tabular forms started to misbehave, the multi-row-delete process raises a No Data Found error. The tabular form is based on a view with a INSTEAD OF trigger to handle the DML. Manually deleting the row in SQL*Plus works fine delete from mytab here pk_id = :pk_id but selecting the same row in Apex and clicking Delete raises the error.
How does one go about troubleshooting & fixing this sort of thing? I tried re-saving the region in the Builder, exporting/importing the entire app, nothing. Running in Debug mode doesn't really provide any additional information, just that the MRD process failed. Tabular forms are the most frustrating, opaque component in Apex, wish they were easier to troubleshoot.
Any ideas?

Hello Vikas,
>> How does one go about troubleshooting & fixing this sort of thing?
By given us a bit more information :)
• Is it a manual Tabular Form (using the ITEM API) or a wizard created one?
• Are the Insert/Update operations work correctly? If not, what is the type of your PK column(s)?
• If the problem is limited to the Delete operation, maybe the problem lies with the checkbox column. Are you sure that on page it is rendered as the f01 column?
• As triggers are involved, can you save the PK that the trigger sees? Is it the expected value?
• Are there any other processes that are fired before the DML process? If so, maybe the problem is with them. You can temporarily disable them and see if it change anything.
>> Tabular forms are the most frustrating, opaque component in Apex, wish they were easier to troubleshoot
Yes, I agree. However, I believe that 4.1 made some serious advancement where Tabular Form is concerned. Having simplified Tabular Form related Validations and Process should make things easier, and as a result, prone to less errors. Still, the main problem is that the type of error you are talking about is usually the result of metadata problems and these are indeed very hard to track.

Problem with multi row delete

Hi, I'm new in apex and I tried to build master detail report on some view. Everything is cool but "delete checked" doesn't work.
"ORA-20001: Error in multi row delete operation: row= , ORA-06502: PL/SQL: numeric or value error: NULL index table key value,"
the problem is that I don't know what is wrong :), I have a special trigger "instead of delete on MY_VIEW", but in this error problem is not explained.
Anybody knows what can be wrong? It is probably a problem with trigger or multi row doesn't work with views? I couldn't find how MRD knows what kind of statement use to delete rows so I don't know if the statement that program used is correct. In debug it lokks that:
0.32: ...Do not run process "ApplyMRU", process point=AFTER_SUBMIT, condition type=REQUEST_IN_CONDITION, when button pressed=
0.32: ...Process "ApplyMRD": MULTI_ROW_DELETE (AFTER_SUBMIT) #OWNER#:MY_VIEW:ITEM1:ITEM2
0.33: Show ERROR page...
0.33: Performing rollback...
thanks for any help
//sorry for english mistakes
edit: it doesn't matter if I use in trigger delete from ... where item1=:OLD.item1 ; or if I use item1=:P4_item1 (which actually saves correct values)
Edited by: user5931224 on 2009-06-13 08:55

I realised that this is not a problem with trigger, I changed trigger to "NULL;" and problem is the same. Maybe sb used master detail on view not only on tables and know what can be wrong in this situation?

Multi Row Delete and then I get a unique contraint violation on my PK

I have a simple table with 2 columns, one a PK. I have a checkbox style, multi-row delete function setup on this (to be honest, APEX set this up automatically).
I removed the add/edit functionality to keep just the delete button and delete procedure.
When I select an item, and then click delete, I get a unique constraint violation that I'm violating my Primary Key.
How can I fix this, or see what it's doing when it tries to delete the row?

Hi,
It sounds as though you haven't properly removed all of the add/edit functionality or that you still have some form of validation and/or computation in place or that you have a trigger that is trying to insert records into, for example, a history table (is the constraint on the table you are deleting from - the error message should tell you this?)
Check that the only process you have is ApplyMRD and that this is pointing to the correct table and has the correct primary key set. Ensure that this has Conditional Processing set for a Request of "MULTI_ROW_DELETE".
Check for any validations - there is no need to perform validations if your user can not insert or update data unless you want to check that they've ticked one or more checkboxes.
Check for processes that could run if the user clicks the Delete button. Validations and processes could be conditional on either the button click or on request = "MULTI_ROW_DELETE".
Review any triggers that you have on the table to ensure that deletions do not try to insert records into another table where the primary key on that table is not being populated.

Andy

Could not delete from specified table?

hi all,
i'm getting this error could not delete from specified table when i execute a delete on dbf file via JDBC-ODBC bridge, when i execute an update table command i get operation must use an updatable query, but i'm not updating the query returned from select statement.
Does anyone have similar problem before??

Hi,
my code is below:
try {
conn=DriverManager.getConnectio("jdbc:odbc:sui","","");
stmt = conn.createStatement();
int r= stmt.executeUpdate("Update Alarms set ACK=True WHERE DT = { d '" + msgdate + "' } AND TM= '" + msgtime + "'");
System.out.println(r+" records updated in Alarms ");
stmt.close();
conn.close();
stmt=null;
conn=null;
catch (NullPointerException e) {System.out.println(e.getMessage());}
catch (SQLException e) {System.out.println(e.getMessage());}
I have an ODBC datasource called sui and a table called alarms, i need to write into the column Ack to true when DT equals msgdate and TM equals msgtime, the error returned is Operation must use an updatable query.
I believe the SQL has no problem because there is no SQL syntax error and i'm not updating any resultset returned from select query.
When i delete, i get could not delete from specified table. Anyone has any idea wh'at's wrong?

How to populate a table based on a row selection from another table.

Hi, i just started to use ADF BC and Faces. Could some one help me or point me a solution on the following scenario .
By using a search component , a table is being displayed as a search result. If i select any row in the resulted table , i need to populate an another table at the bottom of the same page from another view. These two tables are related by primary key . May i know how to populate a table based on a row selection from another table. Thanks
ganesh

I understand your requirement and the tutorial doesn't talk about Association between the views so that you can create a Master-Detail or in DB parlance, a Parent-Child relationship.
I will assume that we are dealing with two entities here: Department and Employees where a particular Department has many Employees and hence a Parent-Child relationship.
Firstly, you need to create an Association between the two Entities - Department and Employees. You can do that by right clicking on the model's entity and then associating the two entities with the appropriate key say, DepartmentId.
Once you have done that, you need to link the two entities in the View section with this Association that you created. Then go to AppModule and make sure that in the Available View Objects: 'EmployeesView' appears under 'DepartmentView' as "EmployeesView via <link you created>". Shuttle the 'DepartmentView' to the right, Data Model and then shuttle
"EmployeesView via <link you created>" to the right, Data Model under 'DepartmentView'.
This will then be reflected in your Data Controls. After that, you simply would have to drag this View into your page as a Master-Detail form...and then when you run this page, any row selected in the Master table, would display the data in the Detail table.
Also, refer to this link: [Master-Detail|http://baigsorcl.blogspot.com/2010/03/creating-master-detail-form-in-adf.html]
Hope this helps.

Deleting from multiple tables

I have a master table and a detail table. I need to delete a set of records from both the master and detail tables based on a criteria. Now if I delete from one table then I will not know which records I have to delete from the other table. So the records needs to be deleted from both the tables using the criteria. My SQL statement to select the records is
<<
select *
FROM TL_RATE A, TL_RATE_DETAIL B
WHERE A.CARRIER_ID = B.CARRIER_ID
AND A.TARIFF_CLASS_ID = B.TARIFF_CLASS_ID
AND A.LANE_ID = B.LANE_ID
AND A.SERVICE_COM_ID = B.SERVICE_COM_ID
AND A.EFFECTIVE = B.EFFECTIVE
AND DATE_INVALID < SYSDATE-365;
>>
Thanks

You don't show what table DATE_INVALID is in. However, you should just delete the matching rows from the OTHER table first then that table. This is very slightly different from the rows returned by your query since your query is an inner join. In other words, you're excluding rows that might exist in one table but not the other. Assuming DATE_INVALID is in TL_RATE ...
delete tl_rate_detail
where (CARRIER_ID, TARIFF_CLASS_ID, LANE_ID, SERVICE_COM_ID, EFFECTIVE) in (
select CARRIER_ID, TARIFF_CLASS_ID, LANE_ID, SERVICE_COM_ID, EFFECTIVE
from tl_rate
where date_invalid < sysdate - 365)
delete tl_rate
where date_invalid < sysdate - 365

Create Trigger to Delete from multiple tables

Hello:
I'm trying to write a trigger which will allow me to delete from multiple records. I have two tables where the record for the same client_id needs to be deleted.
Is it possible to do this? I started writing some code and this is what I have so far:
create or replace trigger app_t1
before delete on <table1> ?? -
for each row
begin
delete from client where clientid = :new.clientid;
delete from key where pk = :newclientid;
end;I'm stuck on the line where I have "before delete on" where I'm supposed to provide a table name. I can only use one table and I need to delete from two.
This trigger is supposed to be used within APEX. In APEX, fields are designated as :P1_clientid where P1 references page 1 of the application. Yet, :P1_clientid is set to the field clientid in the table.
So when I write my trigger, I'm not sure how I'm supposed to set my variables.
Can someone help?
I'm also going to post this into the APEX forum.
Thanks.

It's not clear to me if you are just trying to keep two tables in syn or whether you are trying to achieve something else.
A couple of points though:
- In delete database triggers the :new attributes are NULL. You probably mean to use the :old attributes.
- Is there some relationship between the two tables? If so, setting the foreign key to CASCADE DELETE might do the trick for you.
- Another option - better than a database trigger in my opinion - is to just code a procedure that deletes from both tables and call that one from APEX.

Rob.

ORA-20001: Error in multi row delete operation: ORA-01403: no data

Whenever I attempt a multi-row delete on my master detail page, I recieve the error:
ORA-20001: Error in multi row delete operation: ORA-01403: no dataI have seen in other threads that the primary key attribute of the underlying table needs to be set to 'Show' in the report attributes. I have tried this both with it displaying as 'Hidden' ('Show' is unchecked) and with it displaying as text. Either way still gives me the same error.
Is there anything else not mentioned in the other threads that could be causing this error for me?
Thanks.
BoilerUP

Jimmy,
In your multi row delete process you specify schema name, table and column name. Your report needs to be of type âSQL query (Updateable report)â. And your report needs to include the primary key column of your table. The column or alias name of that report column needs to correspond with the actual column name of your table.

Deleting from multiple tables where few tables have same column name

Hi,
I am new to PL/SQL and need some help. I need to delete data older then X years from some 35 odd tables in my schema and out of those tables 25 tables have same column name on which i can have my "where" clause and rest 10 table have different table names. I am doing something like this :
declare
table_list UTL_FILE.FILE_TYPE;
string_line VARCHAR2(1000);
tables_count number:=0;
table_name VARCHAR2(400);
column_name VARCHAR2(400);
BEGIN
table_list := UTL_FILE.FOPEN('ORALOAD','test7.txt','R');
DBMS_OUTPUT.PUT_LINE(table_list);
LOOP
UTL_FILE.GET_LINE(table_list,string_line);
table_name := substr(string_line,1, instr(string_line,'|')-1);
column_name := substr(string_line, instr(string_line,'|')+1);
DBMS_OUTPUT.PUT_LINE(table_name);
DBMS_OUTPUT.PUT_LINE(column_name);
IF column_name = 'SUBMISSION_TIME' THEN
delete from :table_name where to_date(:column_name)<(sysdate-(365*7));
ELSE
delete from || table_name || where ( || to_date(column_name) || ) <(sysdate-(365*7));
END IF;
END LOOP;
EXCEPTION
WHEN NO_DATA_FOUND THEN
UTL_FILE.FCLOSE(table_list);
DBMS_OUTPUT.PUT_LINE('Number of Tables processed is : ' || tables_count);
UTL_FILE.FCLOSE(table_list);
END;
WHERE the text file "text7.txt" contains list of table name and column names separated by a pipe line. But when I execute the above proc it gives error "invalid table name".
Can something like this be done or is there any other way to execute this task of deletion from 35 tables.
Thanks.

Thanks for replies. I don't know what I am doing wrong but still not getting this damn thing work...This is the proc i am running now :
declare
table_list UTL_FILE.FILE_TYPE;
string_line VARCHAR2(1000);
tables_count number:=0;
table_name VARCHAR2(4000);
column_name VARCHAR2(4000);

UTL_FILE.GET_LINE(table_list,string_line);
table_name := substr(string_line,1, instr(string_line,'|')-1);
column_name := substr(string_line, instr(string_line,'|')+1);
IF column_name = 'SUBMISSION_TIME' THEN
DBMS_OUTPUT.PUT_LINE('do nothing');
ELSE
code_text:= 'begin delete from'|| (table_name) ||'where to_date' || (column_name) || '<(sysdate-(365*7))';
Execute Immediate code_text;
END IF;
END LOOP;
EXCEPTION
WHEN NO_DATA_FOUND THEN
UTL_FILE.FCLOSE(table_list);
DBMS_OUTPUT.PUT_LINE('Number of Tables processed is : ' || tables_count);
UTL_FILE.FCLOSE(table_list);

But it gives following error :

Delete from internal table

Hi,
I want to delete from internal table some regords.
I write code:
delete isrot where bldat < '01.09.2005'.
it doesn't work, what is wrong?
regards,
Joanna

hi,
you write the statement like....
<b>delete FROM isrot where bldat < '01.09.2005'.</b>
now it will work...
To select the lines that you want to delete using a condition, use the following:
<b>DELETE FROM <target> WHERE <cond> .</b>
All of the lines in the database table that satisfy the conditions in the WHERE clause are deleted. The FROM expression must occur between the keyword and the database table.
You should take particular care when programming the WHERE clause to ensure that you do not delete the wrong lines. For example, if you specify an empty internal table in a dynamic WHERE clause, all of the lines in the table are deleted.
If at least one line is deleted, the system sets SY-SUBRC to 0, otherwise to 4. SY-DBCNT contains the number of lines deleted.
follow this link for more information on internal table operation.

WBS elements not deleted from PRPS table

Hi Experts,
In CJ20N transaction:
When I delete a project with project profile (ZABC):
- The project record is completely deleted from 'PROJ' table.
- The WBS records are completely deleted from 'PRPS' table.
When I delete another project with different project profile (ZXYZ):
- The project record is completely deleted from 'PROJ' table.
- The WBS records are NOT deleted from 'PRPS' table.
What is the reason for not deleting records from PRPS table?
Thanks in advance for your valuable answers.

WBS should be having actuals.

Multi-row Delete (MRD) on a view?

All,
I created a tabular form on a view, using an instead of trigger to encapsulate the logic for the data manipulations. Works great--until someone checks a row and hits the delete button, at which point APEX throws this error:
ORA-20001: Error in multi row delete operation: row= 107970-18527, ORA-06502: PL/SQL: numeric or value error: character to number conversion error,
Error multi row operation failedAs far as I can tell, it's not even getting to the trigger; I commented out the body of the instead of delete trigger (replacing it with null), and I'm still getting the same error. I have no validations or processes on the page at this point.
The underlying data of the view requires three columns for a unique identifier, so I've concatenated two of them together as an extra column in the view (creating a varchar2 column), and told the MRD to use the calculated column and the third column as the primary key columns. But even using two of the three numeric columns (tweaking the trigger to use a hard-coded value for the third) as an ID fails miserably.
Any idea what's going on?
Thanks,
-David
(In case it makes a difference, we're on APEX 4.0.1.)
