SQL select query having more than 1000 values in 'IN' clause of predicate.

Question

Hi,
We are executing a select query from a table and showing it through a front end screen. When the count of values given in the 'IN' clause of predicate are exceeding 1000 , it is throwing error.
eg. select * from Employees where emp.Id. in('111',123','121','3232',........1001 Ids)
We are using Oracle version 10.2.0.
Please suggest how to tackle such issue.
Regards,

Answer 1

Use a nested table:
create or replace type numbertype
as object
(nr number(20,10) )
create or replace type number_table
as table of numbertype
create or replace procedure tableselect
( p_numbers in number_table
, p_ref_result out sys_refcursor)
is
begin
open p_ref_result for
     select *
{noformat}     from   employees
     ,        (select /*+ cardinality(tab 10) */ tab.nr
               from   table(p_numbers) tab) tbnrs
     where id = tbnrs.nr;
end;
/{noformat}
Using nested tables will reduce the amount of parsing because the sql statement uses binded variables! The cardinality hint causes Oracle to use the index on employees.id.
