Mysql query by weekday-CodePudding

I want to query by weekday in a given table on a column storing dates. E.g. select * from MY_TABLE where date_column is 'Monday'

I saw a DAYOFWEEK() function in mysql. But this only seems to manipulate the results of the query.

So is such a query even possible?

CodePudding user response：

Use weekday name:

SELECT * 
FROM my_table 
WHERE DATE_FORMAT(date_column, '%W') = 'Monday';

Use weekday index:

SELECT * 
FROM my_table 
WHERE DAYOFWEEK(date_column) = 2 
-- WHERE WEEKDAY(date_column) = 0

CodePudding user response：

The WEEKDAY() function returns the weekday number for a given date.

Note: 0 = Monday, 1 = Tuesday, 2 = Wednesday, 3 = Thursday, 4 = Friday, 5 = Saturday, 6 = Sunday.

you need to use weekday instead of dayofweek
