问题
I have this table
training_schedules
- id
- course_reference
- start_date(date)
- end_date(date)
- year_id(int, fk)
on my form, I have dropdownlist for the month, and another one for the year.
Now as you can see there is a mismatch on the month from form and database column. How can I filter the start_date or end_date column using only the integer value from the dropdownlist and ignore the day and year part of the db column?
I saw some examples but using raw query and using date functions of database which is not good if you consider performance because it is not indexable.
Can I achieve this using Eloquent/Fluent Api of Laravel?
回答1:
If you are using mysql u can use the month() function to get month from date
