I am new to SQL and Stored Procedures so I am not sure this is where I should ask this question.Anyway, in my current project other developers are added many SP into the database. To study how to write SP, I go through some of them. And in one of them I saw a line like below

-- several lines of codesAND pohpoid <> 0 -- several lines of codes
Sp what is this <> code really mean in SQL Stored Procedure?Note : My wild guess is less than or greater than.
