The integer part of the difference is the number of full days, and the decimal part represents a partial day. SQLite default timestamps produce a rather unusual output which is not standards-compliant and there are no easy ways to fix that. This way, you get the difference in days. I do all calculations but the timestamp doesn't match with original timestamp, so if anyone could help please I will appreciate. To calculate the difference between the timestamps in SQLite, use the JULIANDAY()function for both timestamps, then subtract one from the other. Just to be sure, here they are again.Hi people, Im sorry to bother but the example works well for 10 digits timestamp but Chrome's timestamp is formatted as the number of microseconds since January, 1601 so I need to convert to seconds, calculate seconds until and finally add the decimal part of EPOCH. The auto modifier causes the value to be interpreted as either a Julian day number or a Unix timestamp, depending on the actual value. We can see that the results are similar, but there’s obviously a difference due to the amount of time it took me to run each example. From SQLite 3.38.0, we can use the auto modifier in place of the unixepoch modifier: SELECT DATETIME(1793956207, 'auto') Result: 09:10:07. This function was introduced in SQLite 3.38.0 (released 2nd February 2022), so it will only work if you’re using SQLite 3.38.0 or higher: SELECT UNIXEPOCH() The UNIXEPOCH() function is specifically designed to return the a unix timestamp. The default value generated by strftime() would actually be stored as Text. Also, we need to read the SQLite date and timestamp values stored in the SQLite3 database and convert them into Python date and DateTime types. Note 'timestamp' is not a data type known to SQLite (see list here). Most of the time, we need to insert Python date or DateTime value into an SQLite table. The CURRENTTIMESTAMP function is a SQL-standard function supported by almost all database systems such as DB2, Firebird, Microsoft SQL Server, MySQL, Oracle, PostgreSQL, and SQLite. Result: 1646695406 The UNIXEPOCH() Function This lesson demonstrates how to work with SQLite date and timestamp types in Python and vice-versa. the unix timestamp): SELECT STRFTIME('%s') It takes no argument and returns the datetime value. In SQL, CURRENTTIMESTAMP is used to extract the current date and time. We can use the %s format string substitution to return the number of seconds since 00:00:00 UTC (i.e. Introduction to Timestamp to Date in SQL In SQL, timestamp is a function which is used to retrieve the current date and time of the SQL server without the database timezone offset. The STRFTIME() function returns a date and time value in the specified format. SQLite provides us with a couple of ways to get the unix timestamp. Dbstat Virtual Table The DBSTAT virtual table reports on the sizes and geometries of tables storing content in an SQLite database, and is the basis for the sqlite3analyzer. And it’s also possible to use the TIME () function to return just the time portion. You can alternatively use the DATE () function if you only need the date to be returned. The unix timestamp is the number of seconds since 00:00:00 UTC. SQLite Android Bindings Information on how to deploy your own private copy of SQLite on Android, bypassing the built-in SQLite, but using the same Java interface. If you have a Unix timestamp, you can use SQLite’s DATETIME () function with the unixepoch modifier to compute the actual date and time.
