Use of decimal in NVL function
I would like to ask about the NVL function. Is there any difference between these?
I would like to ask about the NVL function.
Which is better:
select nvl(col1,0)
from ...;
or
select nvl(col1,0.0)
from ...;
if col1's type is number.
I would like to know if there is any difference between them.
The only difference is in the format of the literal--if you want a decimal point in your result, then use the second form. The values are the same and there should be no difference in performance, since in the case of a null value Oracle just returns the literal that you've specified.
