Question

Been trying to figure this out for a while now.

I am looking to select rows from a database table in MySQL where the two dates are next to each other.

e.g. 2011-07-20 is next to 2011-07-21.

Many Thanks

Neil

I guess you can JOIN using ADDDATE():

SELECT T1.id, T2.id
FROM myTable AS T1
INNER JOIN myTable AS T2
    ON T1.DATE = ADDDATE(T2.DATE, -1)
WHERE T1.id < T2.id;

The WHERE is to verify that T1 and T2 don’t contain duplicates.
