How can I get the current time in milliseconds in MySQL?

To retrieve the current time in MySQL accurate to milliseconds, you can use the built-in functions NOW() and MICROSECOND().

Here is how to get the current time accurate to milliseconds in MySQL:

SELECT NOW(3);

The (3) in the above SQL query indicates that millisecond-level precision is maintained. After executing this query, the current time will be returned and accurately to the millisecond.

Additionally, if you wish to obtain a more precise timestamp (such as at the microsecond level), you can use the SYSDATE() function and combine it with the MICROSECOND() function to achieve this. Here are the specific steps:

SELECT CONCAT(SYSDATE(), '.', MICROSECOND(6));

This SQL query will return the current time accurate to microseconds (6 digits).

By using the above method, you can retrieve the current time in MySQL accurate to the millisecond or microsecond level.
