Select current months records mysql from timestamp column

Question

I have a mysql DB that has a TIMESTAMP field titled date. How can I select all fields where the month is the current month?

Thanks in advance!

Answer 1

In my opinion, the following is more readable than the accepted answer...

SELECT id, FROM_UNIXTIME(timestampfield) timestamp 
FROM table1
WHERE timestampfield >= DATE_FORMAT(NOW(), '%Y-%m-01')

Note: This would select any records from the next month as well. That usually doesn't matter, because none have been created.

Answer 2

SELECT 'data of your choice '
FROM 'your table'
WHERE
MONTH'datecolumn'=MONTH(CURRENT_DATE )

replace text in ' ' with appropriate from your database

Answer 3

As of 2020, you can use BETWEEN to handle the query from the very beginning.

SELECT *
FROM [TABLE]
WHERE [DATE_FIELD] 
BETWEEN 
CAST('2020-30-01' AS DATE) AND CAST('2020-10-31' AS DATE);

I know is not the most "automatic" way, but from a SQL perspective it is very friendly and straightforward.

Answer 4

UPDATE

A much better index-friendly way to query your data for a range of dates

SELECT id, FROM_UNIXTIME(timestampfield) timestamp 
  FROM table1
 WHERE timestampfield >= UNIX_TIMESTAMP(LAST_DAY(CURDATE()) + INTERVAL 1 DAY - INTERVAL 1 MONTH)
   AND timestampfield <  UNIX_TIMESTAMP(LAST_DAY(CURDATE()) + INTERVAL 1 DAY);

Note: You don't apply any function to your column data, but rather do all necessary calculations on the right side of the conditions (which are constants and are evaluated only once post-execution). This way you allow MySQL to benefit from index(es) that you might have on the timestampfield column.

Original answer:

SELECT id, FROM_UNIXTIME(timestampfield) timestamp 
  FROM table1
 WHERE MONTH(FROM_UNIXTIME(timestampfield)) = MONTH(CURDATE())
   AND YEAR(FROM_UNIXTIME(timestampfield)) = YEAR(CURDATE())

Note: Although this query produces the correct results it effectively invalidates the proper usage of the index(es) that you might have on the timestampfield column (meaning MySQL will be forced to perform a fullscan)
