Call a large SELECT statement using a Procedure (or similiar) w/variables

I have a large SELECT statement that uses prompt (bind) variables. The statement is (> 4000 characters and I need to call it in a Procedure (or similar object) by passing in, say 3 variables.

What is the best way to go about this task?  Assuming that my SELECT is something like this (but > 4000 characters):

SELECT many_cols, FROM many_tables WHERE col1 = &var1 and col2 = &var2 and col3 = &var3.

I'm looking for a high-levell approach, with the general code flow, that I can add the full SELECT statement and call from another application (just as BEPL) with a simple statement - while passing in these three variables.

Thank you.

>>uses prompt (bind) variables

&var1 is not really a bind variable.  It is just a variable.

What are you going to do with the results of the SQL inside the procedure?

Consume it into a (SOA) BEPL process. Yes, a variable should be able to be passed and processed within the SELECT.

I'm open to creative (simple) ways to accomplish the same result:  have a simple procedure (or package or the like) to call from SOA suite.

What I was looking for is what output are you looking for in the procedure?  CLOB, XML, ref cursor, ???

Just add the select in the procedure.

The following example accepts one parameter and returns a ref cursor.  If I did my math right the select statement is over 4000 characters.

It was tested using sqlplus on a 10.2.0.1 database.
create or replace procedure myproc(inVar1 in varchar2, outCur out sys_refcursor)
is
begin
	open outCur for
		select 'Hello' from dual where dummy=inVar1
and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1
and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1
and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1
and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1 and 1=1

I'm following.... I inserted my SQL and compiled (no errors) but when I run the sqlplus setup to test, I get:

ORA-00900: invalid SQL statement

This points to line with:

var myCur refcursor

With 10g sqlplus?

I pasted the script I executed as-is.

Can you post a screenshot of your sqlplus window?

I think i was out of sync - i dropped and recreated and it was able to run.

Just got a error in Toad stating: "List index out of bounds (39)"  which I think is because all the columns - some colums returning a (DATASET) ?

Sorry but I'm not a Toad person.  If it works in sqlplus then I would ignore Toad for now and test with your BPEL code.
