MySQL MICROSECOND() function

MICROSECOND() function

MySQL MICROSECOND() returns MICROSECONDs from the time or datetime expression. The return value is within the range of 0 to 999999. It provides a way to isolate the microsecond part of a time for precise time-based calculations and analysis.

This function is useful in -

• The function is used to capture and analyze extremely fine-grained timing information, useful in scenarios requiring high accuracy.
• The function is used in benchmarking scenarios where the goal is to measure the performance of operations with microsecond-level accuracy.
• MICROSECOND() can be used to calculate time intervals or durations with microsecond-level accuracy.
• MICROSECOND() aids in handling high-frequency data streams that require time-based analysis at the microsecond level.
• MICROSECOND() aids in performance analysis of code or processes that require microsecond-level timing measurements.
• The function is valuable for monitoring network latencies and response times at a very granular level.
• MICROSECOND() is valuable when working with high-precision time calculations, as it allows you to access the microsecond-level details.

Example: MySQL MICROSECOND() function

The following statement will return MICROSECONDs from the datetime 2009-05-18 10:15:21.000423.

Code:

SELECT MICROSECOND('2009-05-18 10:15:21.000423');

Output:

mysql> SELECT MICROSECOND('2009-05-18 10:15:21.000423');
+-------------------------------------------+
| MICROSECOND('2009-05-18 10:15:21.000423') |
+-------------------------------------------+
|                                       423 | 
+-------------------------------------------+
1 row in set (0.00 sec)

Example: MICROSECOND() function with DATE_FORMAT()

The following statement will return MICROSECONDs from a datetime which will come from the CURRENT_TIMESTAMP() and will format it as a datetime expression by DATE_FORMAT() as given in the argument (%Y-%c-%d %H:%i:%s %f) .

Code:

SELECT MICROSECOND(DATE_FORMAT( CURRENT_TIMESTAMP(),'%Y-%c-%d %H:%i:%s %f'));

Output:

mysql> SELECT MICROSECOND(DATE_FORMAT( CURRENT_TIMESTAMP(),'%Y-%c-%d %H:%i:%s %f'));
+-----------------------------------------------------------------------+
| MICROSECOND(DATE_FORMAT( CURRENT_TIMESTAMP(),'%Y-%c-%d %H:%i:%s %f')) |
+-----------------------------------------------------------------------+
|                                                                     0 |
