Introduction

While Hornbill measures intrinsically operate on the basis of arranging records within a specific time period (day/week/month/year), when creating certain types of widgets, there may be occasions when you wish to only return data from a specific time frame. SQL date functions help us do this. The date time functions are only relevant to columns that hold a date/time stamp and would be used in your "WHERE" clause criteria.

Date Functions

Requirement Operator SQL Function
Since First Day of this month >= LAST_DAY(NOW() - INTERVAL 1 MONTH) + INTERVAL 1 DAY
Since Last Day of this month < LAST_DAY(NOW())
Since First Day of last month >= LAST_DAY(NOW() - INTERVAL 2 MONTH) + INTERVAL 1 DAY
Since Last Day of last month < LAST_DAY(NOW() - INTERVAL 1 MONTH)


Requirement Operator SQL Function
Since First Day of Last Week (Sunday) >= CURDATE() - INTERVAL DAYOFWEEK(CURDATE())+6 DAY
Since Last Day of Last Week (Saturday) < CURDATE() - INTERVAL DAYOFWEEK(CURDATE())-1 DAY


Requirement Operator SQL Function
Show Last 10 Days Records >= DATE_SUB(CURDATE(), INTERVAL 10 DAY)
Show Last 1 Months Records >= DATE_SUB(CURDATE(), INTERVAL 1 MONTH)


Requirement Operator SQL Function
Show Todays Records >= curdate()
Show Yesterdays Records >= DATE_SUB(CURDATE(), INTERVAL 1 DAY) and h_datelogged < curdate()


Requirement Operator SQL Function
Calls logged so far this week (from Sunday) >= curdate() - INTERVAL DAYOFWEEK(curdate()) -1 DAY


Requirement Operator SQL Function
