When attempting to insert a datetime value into a SQLite database, users may encounter retrieval errors such as "Unable to read data." To resolve this issue and ensure successful insertion and retrieval, adhere to the following guidelines:
Datetime Value Format:
The datetime value must be formatted in the following ISO 8601 standard format:
1 |
|
This means the format should be "year-month-day hour:minute:second," such as '2007-01-01 10:00:00'.
Syntax for Inserting Datetime Value:
When using the INSERT statement, enclose the datetime value in single quotes, as seen below:

Use of Parameterized Queries:
To avoid potential formatting issues, consider using parameterized queries. This allows you to pass the datetime value as a parameter, allowing the database engine to handle the formatting automatically.
For example, using SQLite's execute() method with a parameterized query:
1 2 3 4 5 6 7 8 |
