Description
This method returns the precision of the field.
Usage
int GetPrecision(void) const
Remarks
In an Oracle database, one column data type is number. If a field has a data type of number it has two additional attributes: scale and precision. The precision is the total number of decimal digits. In Oracle this can range from 1 to 38.
Precision has no meaning for non-number fields.
Return Value
The precision of the number field. On error (which includes calling this method on a non-number field) a 0 is returned.
