oj data grid selection

User_CDX3FOct 6 2021

I am using an oj data grid component in my project with selection mode as Cell. Whenever the user clicks on any cell, the on selection change method is called where i read the selected row and column index. Each row in My data grid shows the details about each employee. I have an delete icon in the last column. When the user hits the delete icon, that particular row is removed from the list. The UI is refreshed with the new data. However, the previously selected row and column is retained and highlighted. So now when I click on the next row or column which was highlighted in the previous selection, it does nothing. I want to programmatically, reset the selected column after every row deletion and let the user to explicitly select a row or cell when he wants to delete it. So how to programmatically reset column selection.

Thanks.

Hi All,

I have a stored procedure which is running forever. The particular stored procedure reads a file and performs validation and inserts into some transaction table.

There are many stored procedures that are called within the main procedure. There might be locks or blocks or some query is taking long time to execute

How do i find out which query in which procedure is taking long time to execute? But sometimes the same procedures completes successfully within few seconds inserting

all the records (10000 recs).

Thanks

Consider to issue SQL below just prior to starting the rogue procedure.

ALTER SESSION SET SQL_TRACE=TRUE; -- ensure the USER has necessary privilege to successfully run this SQL statement

process resultant trace file using TKPROF

I just ran the main procedure now and it ran successfully within few seconds. I don't know why it was not running earlier 1 hour ago. Can someone throw some light on this?

Thanks

Something changed, but we don't know what you have.

Does any of the SQL in your mystery procedure use bind variables?

No, none of the SQL use bind variables. My procedure calls the innermost procedure which is a PRAGMA AUTONOMOUS procedure.

FYI : The innermost procedure has a FOR UPDATE in a select clause. I have issued proper COMMIT/ROLLBACK also in that procedure. Does it have something to do with that? Also, the total record count i am processing is 10000.

Thanks

@John Thorton

However the records are processed successfully and inserted into relevant tables. Only the session keeps hanging in SQL Developer.

Let me know if you need anything else. If the session keeps hanging probably the application would also keep hanging in Production.

Can you someone kindly help on this.

Thanks

Gautam

Hi all,

It's solved. The hanging was due to the excessive dbms_output messages being populated for each of the 10000 records.

Are you using dynamic SQL? Because unless you are, all your SQL will definitely be using bind variables. PL/SQL sorts that out automatically.

BEDE

The most simple thing is to use a log table and log there when the code gets to some place using a store procedure with pragma autonomous_transaction.

Or, you may see what shows in the sys.gv_$open_cursor and sys.gv_$sql for that session of yours, like below:

select sq.*

from sys.gv_$open_cursor oc

join sys.gv_$sql sq on oc.sql_id=sq.sql_id and oc.inst_id=sq.inst_id

where oc.sid=&sid and oc.inst_id=&inst_id

and sq.users_executing>0

;

If it's quite difficult to know which your session is, you may mark that session using the facilities of package dbms_application_info.

BEDE

If you suspect there may be some session blocking:

Select * from sys.gv_$session_blockers

;

And see what you get.
