Estimating a table size

["Rodrigo Sakai" <rodrigo.sakai@xxxxxxxxxxxxxx>]

  Hello all,

 

  I need a tool or something like it, which can give me the estimated size of a table considering all fields, constraints, indexes, etc...

 

  For example:

 

 

  CREATE TABLE products (

     product_id INT8,

     product_name VARCHAR(50),

     product_vendor VARCHAR(50),

     price NUMERIC(10,2),

 

     CONSTRAINT pk_products PRIMARY KEY (product_id),

     CONSTRAINT ck_price CHECK (price >= 0)

);

 

 

CREATE INDEX ix_products ON products (product_name);

 

 

  See that in the example above I have, some fields, some constraints and one index. I want to know (estimate) how much fisical space (KB, MB) it will consume!

 

 

  Thanks in advance!
