The MySQL CURRENT_TIMESTAMP
function returns the current date and time.
This function is actually a synonym for the NOW()
function.
The value is returned in ‘YYYY-MM-DD HH:MM:SS’ or YYYYMMDDHHMMSS format, depending on whether the function is used in a string or numeric context.
Syntax
You can use either of the following two forms:
CURRENT_TIMESTAMP CURRENT_TIMESTAMP([fsp])
Where the (optional) fsp
argument specifies the fractional seconds precision for the return value.
Obviously, if you need to provide the fractional seconds precision, you’ll need to use the second form.
Example
Here’s an example to demonstrate.
SELECT CURRENT_TIMESTAMP;
Result:
+---------------------+ | CURRENT_TIMESTAMP | +---------------------+ | 2018-06-23 11:32:15 | +---------------------+
Fractional Seconds Precision
Here’s an example of using the fsp
argument to specify the fractional seconds precision for the return value.
SELECT CURRENT_TIMESTAMP(6);
Result:
+----------------------------+ | CURRENT_TIMESTAMP(6) | +----------------------------+ | 2018-06-23 11:32:33.766154 | +----------------------------+
Numeric Context
Here’s an example of using the CURRENT_TIMESTAMP()
function in a numeric context.
SELECT CURRENT_TIMESTAMP() + 0;
Result:
+-------------------------+ | CURRENT_TIMESTAMP() + 0 | +-------------------------+ | 20180623113258 | +-------------------------+
You can also use a nonzero value to add or subtract from the return value.
