SQL Date Function NOW()

The NOW() function is a SQL function used to retrieve the current date and time of the system on which the database management system is running. It takes no arguments and returns a datetime value.

Here's an example of how to use the NOW() function in a SQL query:

SELECT NOW();

This query will return the current date and time of the system in the default datetime format of the database management system.

Note that the NOW() function is specific to the database management system you are using, and the syntax and date format it supports may vary slightly depending on the system. Additionally, the NOW() function retrieves the date and time from the system clock of the database management system, and not from any external sources.
