RE: storage requirements for numeric datatypes

Specifying precision and scale does not effect the storage. It depends on the actual values inserted.

Subject: storage requirements for numeric datatypes

Hi listers,

I am working on a sizing estimate for a one billion row table. This table will have ten numeric columns. Is there storage savings if the numeric columns were defined as NUMBER(12,2) versus NUMBER(22,7). Will the storage requirements depend on the actual numeric data values?

Thank you in advance for your help!
