Error: PLS-00103: Encountered the symbol "/" - stored-procedures

Question

I am new to Pl Sql. I am trying to run procedure and getting these errors:
Encountered the symbol "Create" with begin case declare end exception exit for goto if loop mod null pragma raise return select update while with
<< continue close current delete fetch lock
insert open rollback savepoint set sql execute commit forall
merge pipe purge:
I have tried searching for what causes these errors and for examples similar to this, but results were not sufficient. And this is my script:
CREATE OR REPLACE PROCEDURE CommandScript IS
BEGIN
EXECUTE IMMEDIATE 'DROP TABLE sf_tmp';
EXCEPTION
WHEN OTHERS THEN IF SQLCODE != -942
THEN RAISE;
END IF;
create table sf_tmp(smcard varchar2(17),p_line varchar2(1000));
INSERT INTO dec_tmp(DECSCNR,DECSCPSNR)
SELECT TRIM (SUBSTRB (qinputstring, INSTR (qinputstring, '|', 1, 2) + 1,11)) dec_nr,
decoders.decscpsnr FROM bgqueue, decoders WHERE qworktype = 10
AND decoders.decscpsnr > 0 AND decoders.decscnr =

AND LENGTH (TRIM (SUBSTRB (qinputstring,INSTR (qinputstring, '|', 1, 2) + 1,11))) = 11;

Answer 1

I beleive you don't need '/' at line 10.

Answer 2

You can't execute DDL in a procedure natively. Wrap it in an EXECUTE IMMEDIATE
create table sf_tmp(smcard varchar2(17),p_line varchar2(1000));
You don't end your begin statement, which mean your procedure sees
create procedure begin ... declare ... begin ... end ... end
You don't need a declare in compiled code so this should be:
create procedure ... begin ... end ... begin ... end
The second begin ... end being what you want to execute on compilation (i.e. the creating and dropping of your tables)
You can't reference non-existent tables in a procedure. Given that you're allowing for your table to not exist at the beginning you need to wrap this in an EXECUTE IMMEDIATE.
insert into sf_tmp (smcard,p_line) values (m_decno,prod_full) ;
Please start using the ANSI join syntax, rather than joining in your WHERE clause
Oracle recommends that you use the FROM clause OUTER JOIN syntax rather than the Oracle join operator. Outer join queries that use the Oracle join operator (+) are subject to the following rules and restrictions, which do not apply to the FROM clause OUTER JOIN syntax:
LISTAGG() should help you significantly.
A global temporary table should remove the need to perform DDL in your procedure at all.
Without investigating too hard, your entire procedure looks like it can be done in a single INSERT statement...
Lastly, it looks like you're generating partial SQL to be executed later. This can be a valid approach in very specific circumstances, but I'd seriously reconsider whether it is before continuing.
