Question

How do i get all the NULL valued records from the table without using below conditions

"WHERE field_name IS NULL OR field_name = 'NULL' " 

Is there any MySQL inbuilt function to resolve this..?

actually this is what question i have faced in one of the INTERVIEW for MYSQL. i’m very much eager to know the solution for that.

I really appreciate with your answer.Please help me out.

Thanks.

you can try this

select COALESCE(colname,0) from table where
colname != coalesc(colname,0);
