SQLite Data Types: A Complete Overview SQLite uses a dynamic type system for handling data types. Unlike traditional databases that enforce strict type rules, SQLite employs "type affinity," allowing for flexibility in storing and retrieving data. This article delves into SQLite's data types, their...

Import and Export GTFS transit data into SQLite. Query or change routes, stops, times, fares and more. node-GTFS loads transit data in GTFS format into a SQLite database and provides some methods to query for agencies, routes, stops, times, fares, calendars and other GTFS data. It also...
This is similar to AUTO_INCREMENT column in MySQL or AUTOINCREMENT column in SQLite. Floating-point number There are three main types of floating-point numbers: float(n) is a floating-point number whose precision, is at least, n, up to a maximum of 8 bytes. realor float8is a 4-byte...

System.Data.SQLite 會將額外的語意套用至數據行類型,並將其直接對應為 .NET 類型。 這讓提供者有更強型別的感覺,但它有一些粗糙的邊緣。 例如,他們必須引進新的 SQL 語句(TYPES),以在 SELECT 語句中指定表示式的數據行類型。 連接字串 Microsoft.Data.Sqlite 的連接字串關鍵詞少得多。 下表顯示可改用的替代...
Savepoints in SQLite¶ While SQLite supports savepoints, a flaw in the design of thesqlite3module makes them hardly usable. When autocommit is enabled, savepoints don’t make sense. When it’s disabled,sqlite3commits implicitly before savepoint statements. (In fact, it commits before any stat...
The biggest difference between Microsoft.Data.Sqlite and System.Data.SQLite is how data types are handled. As described in Data types, Microsoft.Data.Sqlite doesn't try to hide the underlying quirkiness of SQLite, which allows any arbitrary string to be specified as the column type, and only...
