I've looked throw your help topic of using PL/SQL Tables and I've investigated the sample. But it is not exactly what I am looking for. I can't understand how to pass parameters of the PL/SQL Tables type into stored procedure.

Code: Select all

create or replace procedure TEST1(TXT string_list) is 
  cnt number; 
begin 
  cnt := 0; 
  for v in (select * from table(TXT)) loop 
    cnt := cnt + 1; 
  end loop;  
end TEST1; 

create type string_list is table of varchar2(100);

I need it for the following purposes. I have the SP with the select query which has where Field1 in (Param1) clause. I want to use such a pattern:

Code: Select all

select ... from ... where Field1 in (select * from table(Param1))

If there are other ways of solving my problem, I'm very much appreciated to learn them but using my pattern is more preferable.

Regards, torely.

We have corrected your procedure a bit.

Code: Select all

PROCEDURE TEST(TXT string_list) IS 
  cnt NUMBER; 
BEGIN 
  cnt := 0; 
  FOR v IN (SELECT * FROM TABLE(CAST(TXT AS string_list))) LOOP 
    cnt := cnt + 1; 
  END LOOP;  
END TEST;

To pass the parameter to this SP you can use the following code:

Code: Select all

oracleCommand1.Parameters.Add(new CoreLab.Oracle.OracleParameter("TXT", CoreLab.Oracle.OracleDbType.Table, 0, System.Data.ParameterDirection.Input, false, ((byte)(0)), ((byte)(0)), "", System.Data.DataRowVersion.Current, null, 0, "SCOTT.STRING_LIST"));
oracleCommand1.Parameters["TXT"].Value = new string[] { "aa", "bb"};
