I'm trying to pass an array of (varchar) data into an Oracle procedure. The Oracle procedure would be either called from SQL*Plus or from another PL/SQL procedure like so:

BEGIN
 pr_perform_task('1','2','3','4');
END;

pr_perform_task will read each of the input parameters and perform the tasks.

I'm not sure as to how I can achieve this. My first thought was to use an input parameter of type varray but I'm getting Error: PLS-00201: identifier 'VARRAY' must be declared error, when the procedure definiton looks like this:

CREATE OR REPLACE PROCEDURE PR_DELETE_RECORD_VARRAY(P_ID VARRAY) IS

To summarize, how can I pass the data as an array, let the SP loop through each of the parameters and perform the task ?

I'm using Oracle 10gR2 as my database.
