Question

DROP TABLE IF EXISTS product;

Asked by: Peewee

Hi There,
simple question i imagine..

i want to drop my table if it exists so that i can rebuild it.. It fails on the drop command, it doesn't like specified where it is..  Can you tweak or show me a better way?

cheers Peewee

here's what i got so far:

set serveroutput on;
REM lets try testing to see if a table exists

declare
    cursor c is select null from user_tables where table_name = 'PRODUCT';
    x number;
begin
    open c;
    fetch c into x;
    if (c%NOTFOUND) then
        dbms_output.put_line('Product Table Does Not Exist');
        -- Do Nothing
    else
        dbms_output.put_line('Product Table Exists');
        drop table PRODUCT;
    end if;
end;
/

create or replace table PRODUCT (
        upc varchar(15) primary key,
        description varchar(20) not null,
        linespeed number(5) not null,
        price_plan number(5)not null,
        product_count number(3) not null,
        published char(1) default 'N',
        constraint PRODUCT_UQ UNIQUE (product_count),
        constraint published_chk CHECK(published IN('Y','N')),
        constraint linespeed_chk CHECK(linespeed IN(256,512,1000,2000))
);
