I am trying to write a pl/sql program to delete a bunch of records. This came up because a developer wrote a sql statement to delete everything but it was running out of undo space. I thought it would be easy to throw into a pl/sql program and commit along the way to avoid that issue.
The gist of it is that I am building a list of values to use in the delete statement and passing it in as a bind variable but am getting an error when executing it. The SQL statement is "delete from table where column in (num1, num2, num3, num4,...num50);" I am using a varchar to build the num1, num2, num3... list and then trying to pass the whole thing to sql statement on the execute immediate. When I do, I get an invalid number error. I think I am missing something obvious but can't figure it out.
Here's the output from when I execute it. I added the echo'ing of the sql statement and the list_of_values while trying to debug. I have tried putting the ()'s in the list_of_values but get the same error.
SQL> exec epicenter_delete.whack_it_all
delete from pol_predetail where ParentObjID in (:1)

SQL> The program goes something like this:

END LOOP; Any/all ideas/help appreciated.
