Question

I have a table that has 3 fields, ID, Name, Address. (Name and Address are type String)

There are instances, where the Address is left Null. How do i write an SQL to get all address that are not Null.

My workings so far;

select * from Hotel where Address != NULL

Zero results were printed, after executing this command (even though there are such records stored in the DB). How should i alter the SQL ?

I am using MySQL

Answer 1

You need to use IS NOT NULL instead of != NULL

select * from Hotel where Address IS NOT NULL
