plSQL Syntax For Writing Stored Procedure w/ 3 Variables - oracle

Question

I have this long block of SQL statements I need to make a stored procedure for that accept 3 variables. The variables are invoice, NewDate, TransactionDate and the datatypes are integer, date, and date respectively. I've tried to create the stored procedure, but the syntax is messing me up. I'll be calling the stored procedure using Coldfusion and cfstoredproc, hence the pound signs. Not that I need any help with the ColdFusion. Just trying to provide as much info as possible.
truncate table fix_the_date; commit;
insert into fix_the_date
(Location,Invoice,NewDate,TransactionDate)
values
('Corporate', '#invoice#'
, to_date('#NewDate#', 'mm/dd/yyyy')
,to_date('#TransactionDate#','mm/dd/yyyy'));
commit;
<!--- About a dozen other queries go here that I won't waste your time with--->
Update 1:
Below is what I have for the Stored Procedure as of now. I'm getting the following error:
Error Executing Database Query. [Macromedia][Oracle JDBC
Driver][Oracle]ORA-01858: a non-numeric character was found where a
numeric was expected ORA-06512: at "THEDB.FIXMISSINGDATE", line 13
ORA-06512: at line 1 The error occurred on line 4
CREATE OR REPLACE PROCEDURE THEDB."FIXMISSINGDATE" (Invoice integer, NewTransactionDate date, TransactionDate date) IS
BEGIN
EXECUTE IMMEDIATE 'TRUNCATE TABLE FixTheDate;
commit;
EXECUTE IMMEDIATE 'TRUNCATE TABLE DeletePayTrans';
commit;
insert into FixTheDate(Site, Invoice_No, Pay_Date, Old_Date)
values ('Corporate', 'TO_CHAR(#Invoice#)','#NewTransactionDate#','#TransactionDate#');
commit;
/*******************************
Plus a bunch of other queries here
*******************************/
END FIXMISSINGDATE;
/
Update 2: Per feedback in comments, removed pound signs
CREATE OR REPLACE PROCEDURE THEDB."FIXMISSINGDATE" (Invoice integer, NewTransactionDate date, TransactionDate date) IS
BEGIN
EXECUTE IMMEDIATE 'TRUNCATE TABLE FixTheDate;
commit;
EXECUTE IMMEDIATE 'TRUNCATE TABLE DeletePayTrans';
commit;
insert into FixTheDate(Site, Invoice_No, Pay_Date, Old_Date)
values ('Corporate', TO_CHAR(Invoice), NewTransactionDate, TransactionDate);
commit;
/*******************************
Plus a bunch of other queries here
*******************************/
END FIXMISSINGDATE;
/

Answer 1

Your issue probably relates to trying to issue DDL statements in a stored procedure (see here).
I'm going to assume that your NewDate and TransactionDate are also varchar2 (since your insert statement won't work if they're actually dates).
CREATE OR REPLACE PROCEDURE my_proc(
invoice IN integer,
NewDate IN varchar2,
TransactionDate IN varchar2) AS
BEGIN
EXECUTE IMMEDIATE 'TRUNCATE TABLE fix_the_date';
INSERT INTO fix_the_date (Location,Invoice,NewDate,TransactionDate)
VALUES ('Corporate', invoice, TO_DATE(NewDate, 'mm/dd/yyyy'),
TO_DATE(TransactionDate,'mm/dd/yyyy'));
COMMIT;
END;
/
...or if you really are passing dates:
CREATE OR REPLACE PROCEDURE my_proc(
invoice IN integer,
NewDate IN date,
TransactionDate IN date) AS
BEGIN
EXECUTE IMMEDIATE 'TRUNCATE TABLE fix_the_date';
INSERT INTO fix_the_date (Location,Invoice,NewDate,TransactionDate)
VALUES ('Corporate', invoice, NewDate, TransactionDate);
COMMIT;
END;
