The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

DROP TABLE IF EXISTS product;

Tags: table, exists, drop
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))
);
