Select with date dayofmonth()

In this page, we have discussed how to use MySQL dayofmonth() function. This is useful to retrieve the day of a month for a given date.

Example:

Sample table: publisher


Code:

SELECT pub_name,pub_city,estd,dayofmonth(estd)
FROM publisher
WHERE dayofmonth(estd)>5;

Explanation

The DAYOFMONTH() function is used to get the day of a month of the establishment date of the publishers, if the day of a month is more than 5. The statement also returns pub_name,pub_city and estd form publisher table.

mysql> SELECT pub_name,pub_city,estd,dayofmonth(estd)
    -> FROM publisher
    -> WHERE dayofmonth(estd)>5;
