The preceding space: the column name would simply be “Expiration date”.

This constant is meant to be used with the detect_types parameter of the Note that the SQLITE_THREADSAFE levels do not match the DB-API 2.0 execute ( """ select * from pragma_compile_options where compile_options like 'THREADSAFE=%' """ ). You can check the underlying SQLite library’s compile-time “Threads may share the module, but not connections.” However, this may notĪlways be true. Integer constant required by the DB-API, stating the level of thread safety The version number of the run-time SQLite library, as a tuple of integers. The version number of the run-time SQLite library, as a string. The version number of this module, as a tuple of integers. The version number of this module, as a string. However, the DB-API does not allow multiple values for Parameter styles, because that is what the underlying SQLite library databases commands.The sqlite3 module supports both qmark and numeric DB-API

HOW TO CREATE SQLITE DATABASE INSTALL
To install it using apt, use the command:
You can also install SQLite using your package manager. To launch the SQLite shell, run the sqlite3 binary. Once you unzip the archive, you should have sqlite3 binary.
HOW TO CREATE SQLITE DATABASE DOWNLOAD
Select the SQLite tools for your system and download them. To get SQLite for your Linux system, open your browser and navigate to: This tutorial will cover using SQLite shell to create databases, create tables, and insert data. SQLite provides an interactive shell that you can use to interact with databases and the SQLite engine. It runs in memory, which allows you to run the database without any server. SQLite does not offer a client-server database model, which eliminates the need for installation and management. SQLite is simple and powerful, providing rich features in other major DBMS systems such as MySQL, PostgreSQL, and many more with minimal or no configuration. SQLite is an open-source relational database management system developed for embedded systems.
