date-range

I'm trying to write a query that will check today's date against my table columns date1 and date2 in mysql/php.. This is what I'm after: 'events' table: date1 = start date (XXXX-XX-XX) date2 = end date (XXXX-XX-XX) query: select * from events where 2012-01-18 between date1 and date2 (or equal to date1 and date2) But I'm not sure how to go about it.. any help would be appreciated :) EDIT: Maybe I was unclear.. if todays date = '2012-01-18' I need it to find results if today's date is between the date range of date1 and date2.. So date1 may be '2012-01-04' and date2 may be '2012-01-21'.. so if

To make this question more generalized, I believe it could also be rephrased as: Creating a rolling temporally sensitive factor variable . Though an uncommon requirement, this could be utilized for many different data sources. I have a series of non-uniform time data with > 1 record per day for thousands of users. I want to create a new column player_type that keeps track of a rolling 30 day definition of their behavior. The behavior is defined by what games they play; the column 'games' is a factor of gameA, gameB. There are thus three types of behaviors: Exclusively plays GameA - 'A'

I have a requirement to write a stored procedure that accepts a start date, end date and a frequency (day, week, month, quarter, year) and outputs a result set based on those parameters. Obviously, the simple part is the query by date range, but how do you group by frequency? So if have a set of raw data like this: Date Count --------------------- 11/15/2011 6 12/16/2011 9 12/17/2011 2 12/18/2011 1 12/18/2011 4 And I call my stored proc like this: sp_Report '1/1/2011', '12/31/2011', 'week' I would expect results like this: WeekOf Count --------------------- 11/19/2011 6 12/17/2011 11 12/24

I want to compare two dates (StartDate and EndDate) and check whether one is before the other. The simplest solution is to just do it on the backing bean and "short-circuit" the method. However this validation does not happen concurrently with the other form validations. For example if I have another field that requires validation (besides the dates) and has invalid input, I will only get a message for that specific field. Only if the other fields are valid will I get the date validation based on the backing bean. Anyone have a solution? BalusC However this validation does not happen

I keep a record of logins in a table. I have columns for id, ip, date and time. From that record of logins I wanna fetch logins made only in the last hour. I'm sweeping through the MySQL docs on time and date functions, but I just can't seem to combine them correctly. Can somebody help me? Make use of the DATE_SUB() and Now() functions: select count(*) as cnt from log where date >= DATE_SUB(NOW(),INTERVAL 1 HOUR); Hope it helps you : ) If you want to implement this into a cronjob, you need to specify the start and end. For example, at 2pm, if you want to get the data for the past hour from 13

Having trouble making a SQL query for a small booking system, i have a table containing two entries which holds two different dates and a number. Nr DateFrom DateTo ---------------------------- 1 2015-01-01 2015-01-03 2 2015-01-05 2015-01-08 I want to query where i can enter two different dates and only return the number of the date range in the table that doesn't collide with the entered date range. For example if i enter the dates 2015-01-02 and 2015-01-04 it would return Nr 2 and 2015-01-05 and 2015-01-08 would return Nr 1. SELECT * FROM yourTable WHERE DateFrom > @rangeEnd OR DateTo <
