This method works; I have some code using it.
The only problem, it could be slow (on large tables), because index on
<code_column> will not help.

SELECT <columns>
FROM <sometable>
WHERE INSTR(','||<list_of_comma_separated_codes>||',' ,
','||<code_column>||',' ) > 0;
(1). Concatenate Commas at BOTH ENDS of the string containing
different code values. e.g. If the string is
'101,102,554,336,678,301,201,199' , the concatenate commas
on both ends to make it ',101,102,554,336,678,301,201,199,'
this is to make sure that EVERY code ( including the first
and the LAST ) confirms to the pattern <,><value><,>
(2) For each row in the table, use INSTR() function to see whether
the pattern <,><value of columna><,> is CONTAINED in the string
INSTR() is used so that pattern matching can be used instead of
any range checking etc on the string. The actual code values in
the string can be IN ANY ORDER.

I need to do an insert select of the form
insert into tab2
select col1
from tab1
where col2 in (inlist of numbers);
I do not know how many values will be in my inlist at runtime. With
strings
I just build a big string. How do I build an 'inlist' of numbers at
runtime?
Im using a cursor to determine which values need to be added to my
inlist. I
think I can do some kind of cast, but im not familiar with it.
Im on 8i. I do not want to j ust run this inside my cursor. It could
then
execute 300-400 times and will run all day.
