The julianday() and strftime() functions provide alternate ways to format datetime values. Next, let’s look at other useful date functions like julianday(), strftime(), etc. This provides flexibility to store dates in compact formats but convert to human-readable datetimes when required. We can use datetime() to convert between storage formats: SELECTĭatetime(julianday(' 09:30:45')) AS julianday_format,ĭatetime(strftime('%s',' 09:30:45')) AS unix_format This provides an easy way to do date math in SQLite queries! Converting Datetime Storage Formats in SQLite We can use modifiers with datetime() to perform arithmetic on dates/times: SELECTĭatetime(' 09:30:45', '-1 day') AS yesterday,ĭatetime(' 09:30:45', '+1 month') AS next_month These are convenient for extracting the required date or time component from a datetime value. ![]() The time() function returns just the time part: SELECT time(' 09:30:45') The date() function returns just the date part of a datetime: SELECT date(' 09:30:45') SQLite also provides separate date() and time() functions: date() To format a date/time string: SELECT datetime(' 09:30:45') To get the current date/time: SELECT datetime('now') Let’s see some examples: Formatting Dates and Times in SQLite It accepts a date/time value as the first argument followed by optional modifiers. The syntax is: datetime(timestring, modifier, modifier.
