WHERE Clause Examples

Using the date() function always returns a date of the form:
  • YYYY-MM-DD

Where:

YYYY [0000-9999]

MM [01-12]

DD [01-31]

Given a table with the following columns and values for 2016-12-24 00:00:00:
Columns Data Type Values
dtm datetime [1482566400, 0]
dtmstr string “2016-12-24T00:00:00”
dtmlong long 1482566400
julianday double 2457746.50000
Assuming all columns of a row are loaded with a date or time value that contains the date 2016-01-01, the following are examples of using the Date() function in a WHERE clause: 
SELECT * FROM mytable WHERE date(dtm)=’2016-12-24’
SELECT * FROM mytable WHERE date(dtmstr)=’2016-12-24’
SELECT * FROM mytable WHERE date(dtmlong,’unixepoch’)=’2016-12-24’
SELECT * FROM mytable WHERE date(julianday)=’2016-12-24’
