SQL > SQL Date Functions

In this section, we cover common date functions seen in SQL. Different database systems have different formats for date-type data, and each RDBMS may employ different date functions, and there may also be differences in the syntax for each RDBMS even when the function call is the same. All such differences are explained in each section. Please note that we do not list all possible SQL date functions in this tutorial. Rather, the most commonly used ones are covered.
