Hi Jean-Luc,

Oracle has a maxium of 38 digits of precision for numbers.

Oracle suppports ANSI integer datatypes like INTEGER but internally converts them all to Oracle's built-in datatype NUMBER(n). So to specify the largest possible integer :

create table foo ( large_number NUMBER(38));

Check the on-line documentation or
