> 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.
