I wanted to know if we have any technique by which we can calculate the value which needed to be set for a LIMIT clause of bulk collect operation. For example below, lets say our cursor has 10 Million records..What is the value which we can set for LIMIT clause to have optimum performance. Is there any way we can calculate it. decalre cursor c_emp is <some select query> var <variable> ; begin open c_emp; loop fetch c_emp bulk collect into var limit 2; exit when c_emp%NOTFOUND; end loop; close c_emp; end; Use an implicit cursor in a cursor FOR LOOP. It makes the code simpler and the default

I have a requirement to display user available time in Hours:Minutes:Seconds format from a given total number of seconds value. Appreciate if you know a ORACLE function to do the same. I'm using Oracle. Thank you for your time. If you're just looking to convert a given number of seconds into HH:MI:SS format, this should do it SELECT TO_CHAR(TRUNC(x/3600),'FM9900') || ':' || TO_CHAR(TRUNC(MOD(x,3600)/60),'FM00') || ':' || TO_CHAR(MOD(x,60),'FM00') FROM DUAL where x is the number of seconds. Try this one. Very simple and easy to use select to_char(to_date(10000,'sssss'),'hh24:mi:ss') from dual;

I'm looking for a good explanation on how to test an Oracle stored procedure in SQL Developer or Embarcardero Rapid XE2. Thank you. Something like create or replace procedure my_proc( p_rc OUT SYS_REFCURSOR ) as begin open p_rc for select 1 col1 from dual; end; / variable rc refcursor; exec my_proc( :rc ); print rc; will work in SQL*Plus or SQL Developer. I don't have any experience with Embarcardero Rapid XE2 so I have no idea whether it supports SQL*Plus commands like this. DCookie Something like this lets you test your procedure on almost any client: DECLARE v_cur SYS_REFCURSOR; v_a

In my project i use oracle as primary database and i've faced a problem with parsing clob. So suppose we have a clob with value aaaaaa cccccc bbbbbb And it's stored in table test ... I need to write plsql procedure to get this clob and split it so that i will have array with three items [aaaaaa,cccccccc,bbbbbbb]. Is there any possible solutions? Pierre-Gilles Levallois Here is a piece of code that works. I suggest that you use explicit cursors instead of implicit ones (FOR i IN (select...)), for performance purpose. First here is the script to create testcase. create table test (c clob);
