Can't replace procedure

Question

Hi:
I am using Squirrel as the client tool using JDBC RAC driver against Oracle 11.1. I am trying to replace an existing Oracle procedure with:
CREATE OR REPLACE PROCEDURE MY_PROC
AS
BEGIN
DELETE FROM table1 WHERE IEX_DATE >= (select max(idate) from table1) - 20;
DELETE FROM table2 WHERE IEX_DATE >= (select max(idate) from table2) - 20;
DELETE FROM table3 WHERE IEX_DATE >= (select max(idate) from table3) - 20;
DELETE FROM table4 WHERE IEX_DATE >= (select max(idate) from table4) - 20;
END;
It fails with the error:
Query 1 of 5, Rows read: 0, Elapsed time (seconds) - Total: 0.047, SQL query: 0.047, Building output: 0
6,326 Row(s) Deleted
Query 2 of 5, Rows read: 0, Elapsed time (seconds) - Total: 0.672, SQL query: 0.672, Building output: 0
12,097 Row(s) Deleted
Query 3 of 5, Rows read: 0, Elapsed time (seconds) - Total: 1.25, SQL query: 1.25, Building output: 0
5,040 Row(s) Deleted
Query 4 of 5, Rows read: 0, Elapsed time (seconds) - Total: 0.531, SQL query: 0.531, Building output: 0
Error: ORA-00900: invalid SQL statement
SQLState: 42000
ErrorCode: 900
Error occured in:
END
What am I doing wrong? I've tried different things but nothing seems to give me an executable procedure.

Answer 1

Looks to me like Squirrel (whatever tool that is) processes SQL statements, so has performed the DELETE statements it's found, but doesn't know about PL/SQL code.
What happens if you run the same create procedure statement through SQL*Plus instead?
