What do you mean.  Are you looking to a where column is null?
Or you want to do a select where the only thing you get us column,null.?

i have a maximum of 80 to 90 columns in my table in that i want to know what are the fields are empty in that particular row . so that next time we can update in the empty field. its possible?
you would need to query for each row individually, or you have to convert the 80-90 column table into a three column table
1,23,null or empty,null or empty
new table/representation (Pivot/unpivot)

IDcolumn (column1), name of column, value
1,column3,null or empty
1,column4,null or empty
not sure what your table design is nor why you would be looking to fill an empty column in a non related row

in this case you will have a select * from newtable where value is null or length(value)=0
