M. m". html. Other database management systems will have similar versions of these functions. • Option 2: Use the more sophisticated date_format() MySQL function. This function takes a series of string specifiers for how you want the date to be formatted. There is a very long list of these specifiers in the MySQL documentation. A completed example to convert the date into our desired format is shown in the following code: SELECT date_format(date, '%l:%i%p, %W, %M %e, %Y') FROM message WHERE mid=52; Result: 4:51AM, Friday, January 21, 2000 This is pretty close to what we said we wanted, and it is much shorter than Option 1.
Here is a working example that will look for the word Sent: and extract the following characters up to the > symbol and then turn these characters into a real MySQL datetime data type: SELECT str_to_date( substring_index( substring_index(reference,'>',3), 'Sent: ', -1 ), '%W,%M %e, %Y %h:%i %p' ) FROM referenceinfo WHERE mid=79; Result: 2000-08-17 18:29:00 Now we have a datetime value that is ready for inserting into a new MySQL column or for performing more date functions or calculations on it.
