Cherry25 Posted May 25, 2012 Report Share Posted May 25, 2012 Hello all. I am learning Oracle pl/sql. I want to know how can we find empty columns in a table. (How to find columns which have all null values in it?) I tried using count(column_name), but the drawback is I've to go column by column which doesn't look effective to me. Can u guys pls help me with this.. Thanks Quote Link to comment Share on other sites More sharing options...
me1233 Posted May 27, 2012 Report Share Posted May 27, 2012 When you say empty columns you mean column which are completely null?
