I am working with MySQL ver 5.1 on a Ubuntu Linux x86_64.
I am new to both SQL and MySQL.
I have been able to query out most of the data I need from my tables
without any issues but his one has stumped me.
I am trying to query data associated with specific dates.
The dates are not sequential but somewhat sporadic. I would like to
query out data/dates that are every 4 days from a starting date.
2006-4-17, 2006-4-21, etc.
I have tried ADDDATE('2006-4-14',interval 4 day)<=Date_col
but it give me only the next date 2006-4-21.
any help would be greatly appreciated,
