With these it helps possibly something is happening in the session in between?
Try checking for the existence of the table before it's dropped:

it helps some times The rule is pretty much, choose a table variable as the default. Then re-assess the situation in the following circumstances:
If you want to use transaction rollback If you want to pass the resultsets of your tables from one stored procedure to another If you want the query optimizer to be able to work out how best to run a complex query If you’re getting really clever with dynamic SQL, you need a temporary table.
Is it a best practice to drop the temp table after using it, in addition to before creating the temp table?

it fixes the issue Usually, it is considered a good practice to free up resource as long as you don't need it anymore. So I'd add DROP TABLE at the end of stored procedure.
Temporary table lives as long as connection lives. Usually, applications use connection pooling (it is configurable) and connection doesn't close when you call Connection.Close. Before connection re-usage, client executes special stored procedure (sp_reset_connection) which does all clean-up tasks. So temp tables will be dropped in any case, but sometimes after some delay.

will help you There are two ways to check the existence of temp table and recreate it , If there is table called temp TRUNCATE it otherwise create new table.
code :
IF Object_id('temp') IS NOT NULL
  TRUNCATE TABLE temp
ELSE
   CREATE TABLE temp
    (
       id INT
    );
CREATE TABLE temp(col VARCHAR(100));
INSERT INTO temp VALUES ('a');

IF Object_id('temp') IS NOT NULL
  TRUNCATE TABLE temp
ELSE
    CREATE TABLE temp
    (
       id INT
    );

INSERT INTO temp VALUES (1);  
╔═════╗
║ col ║
╠═════╣
║   1 ║
╚═════╝
IF Object_id('TEMPDB..#temp') IS NOT NULL
  DROP TABLE #temp

CREATE TABLE #temp
(
       id INT
); 
CREATE TABLE temp(col VARCHAR(100));
INSERT INTO temp VALUES ('a');

IF Object_id('temp') IS NOT NULL
  DROP TABLE temp

CREATE TABLE temp
(
       id INT
)    

INSERT INTO temp
VALUES (1);  
╔════╗
║ id ║
╠════╣
║  1 ║
╚════╝

Any of those help Just change out your logic flow a little. If all that matters is that #temp is empty when the INSERT happens, this should do what you need.
code :
create table #temp (id int)
create table #swap (id int)

<Add loop logic here>

truncate table #temp

insert #temp(id)
select id from #swap

<Close out loop logic>

drop table #swap
drop table #temp

To fix the issue you can do In Unix, connecting to oracle server, I create a temp table on commit preserve rows. I then first truncate the table then I go to drop the table. Trying to drop the table I receive the following error: , Seems to me, the error is pretty clear:
