> A filter condition is the predicate expression specified in the WHERE clause of a SQL select statement.  A predicate can be a compound logical expression with logical AND, OR, NOT operators combining multiple single conditions.  A single condition usually has comparison operators such as =, <, <=, >, >=, ‘like’, etc.
