Hi

After getting the data from the database to the dataset I am calculating one
more field which involves devision.

Do I need to check ISNULL for TOTFLRAREASQFTNBR when putting this in the
denominator.
Since I already have put a check condition so do I need put one more while
putting the same in the denominator.
I am using below expression for the clculation of the field

IIF(ISNULL(TOTFLRAREASQFTNBR, 0) 0, ISNULL(BLDG_VAL_AMT, 0) /
TOTFLRAREASQFTNBR" +
", NULL)";

Hi Vishnu,

This depends on how the expression is evaluated.

If the conditional expression is false, the true expression will not be
evaluated. So you don't need to use ISNULL to evaludate it again.
