How Can I Successfully Insert and Retrieve Datetime Values in SQLite?

Inserting Datetime Values into SQLite Databases

When attempting to store datetime values in SQLite, users may encounter an error when retrieving the values despite a seemingly successful insertion. To resolve this, it is essential to adhere to the correct datetime format.

The correct format for datetime values in SQLite is 'yyyy-MM-dd HH:mm:ss'. This means that the date should be presented in the year-month-day format, while the time should be expressed as hours:minutes:seconds.

For instance, the following statement correctly inserts a datetime value into a table named 'myTable':

INSERT INTO myTable (name, mydate) VALUES ('fred', '2009-01-01 13:22:15')

To avoid any potential formatting issues, it is highly recommended to use parameterized queries. Parameterized queries utilize placeholders (?) instead of values in SQL statements. You can then bind the values to the placeholders during execution. This approach ensures that the correct formatting is always applied.

The following code snippet demonstrates how to use a parameterized query to insert a datetime value into a SQLite database:

String sql = "INSERT INTO myTable (name, mydate) VALUES (?, ?)";
PreparedStatement statement = connection.prepareStatement(sql);
statement.setString(1, "fred");
statement.setString(2, "2009-01-01 13:22:15");
statement.executeUpdate();

By following the correct datetime format and utilizing parameterized queries, you can ensure that datetime values are stored and retrieved correctly from SQLite databases.
