Sqlite commands date between2/4/2024 Result: datetime('now') strftime('%Y-%m-%d %H:%M:%S', 'now')Īs with all SQLite date and time functions, datetime() only works for dates between 00:00:-12-31 23:59:59 (julian day numbers 1721059.5 through 5373484.5).įor dates outside that range, the results are undefined. The datetime() function is just a more convenient way to do it. The following illustrates the syntax of the inner join. The A table links to the B table using a foreign key column named f. The INNER JOIN clause combines columns from correlated tables. The datetime() function returns exactly the same result that strftime('%Y-%m-%d %H:%M:%S'. To query data from multiple tables, you use INNER JOIN clause. Result: 23:58:57 datetime() vs strftime() Here’s an example that uses the Julian Day as the time string. If only the time part is supplied, then the date is set to. If you provide just the date part, the time part will be set to all zeros. The above examples use now as the time string, but you can provide any valid time string. Here it is again comparing the original local time with the modified result: SELECTĭatetime('now', '+3 hours', 'localtime') AS "Modified" Therefore, you may get a different result, depending on your local time. If database is opened successfully, it returns a connection object. You can use ':memory:' to open a database connection to a database that resides in RAM instead of on disk. It then adjusts the time string so that it displays local time. This API opens a connection to the SQLite database file. The reason it does this is because the localtime modifier assumes the time string provided is in Universal Coordinated Time (UTC). In my case, the localtime modifier resulted in the time being moved forward. SELECT datetime('now', '+3 hours', 'localtime') Here’s an example of adding another modifier to the previous example. Multiple ModifiersĪs mentioned, you can add one or more modifiers. Given the original time, this also resulted in the date being moved forward to the next day. In this case, I added three hours to the time. We can modify the previous result by using a modifier. The now time string is converted into the current date and time. Description The SQLite BETWEEN Condition is used to retrieve values within a range in a SELECT, INSERT, UPDATE, or DELETE statement. Here’s an example to demonstrate the datetime() function being used with one argument. Home SQLite SQLite: BETWEEN Condition This SQLite tutorial explains how to use the SQLite BETWEEN condition with syntax and examples. If you provide a modifier, it must be a valid modifier. ![]() The timestring argument must be a valid time string. The syntax goes like this: datetime(timestring, modifier, modifier. A modifier allows you to change the date, such as add a number of days, set it to local time, etc Syntax To use this function, you need to provide a time string, plus any (optional) modifiers. It returns the date in this format: YYYY-MM-DD HH:MM:SS ![]() The SQLite datetime() function enables you to return a date and time value based on a time string and any modifiers.
