The sqliteonconflict parameters accept a string argument which is just the resolution name to be chosen, which on SQLite can be one of ROLLBACK, ABORT, FAIL, IGNORE, and REPLACE. Open () Opens a connection to the database using the value of ConnectionString. ON CONFLICT - in the SQLite documentation New in version 1.3. Template (3) is used for precompiled binaries products. Template (1) is used for generic source-code products and templates (2) is used for source-code products that are generally only useful on unix-like platforms. Load Extension (String, String) Loads a SQLite extension library. Templates (1) and (2) are used for source-code products. However, sqlite does have its own website and documentation. I can find documentations on core data at apple's developer, but there seem to be no documentation on sqlite. SQL ( string ) ¶Ī Composable representing a snippet of SQL statement. Returns schema information for the data source of this conneciton. I'm currently learning ios core data and I understand that core data is based on sqlite. The method is automatically invoked by execute(),Įxecutemany(), copy_expert() if a Composable is SqliteConnectionStringBuilder: Provides a simple way to create and manage the contents of connection strings used by SqliteConnection. SqliteConnection: Represents a connection to a SQLite database. ParametersĬontext ( connection or cursor) – the context to evaluate the string into. Represents a SQL statement to be executed against a SQLite database. * is also supported with an integer argument: the result is aĬomposed instance containing the left argument repeated as many times as DB4S uses a familiar spreadsheet-like interface, and complicated SQL commands do not have to be learned. DB4S is for users and developers who want to create, search, and edit databases. Will be a Composed instance containing the objects joined. DB Browser for SQLite (DB4S) is a high quality, visual, open source tool to create, design, and edit database files compatible with SQLite. Composable ( wrapped ) ¶Ībstract base class for objects that can be used to compose an SQL string.Ĭomposable objects can be passed directly to execute(),Įxecutemany(), copy_expert() in place of the queryĬomposable objects can be joined using the + operator: the result Being a very lightweight database management system, it was named SQLite. No administration was required for operating a program in SQLite. ORM stands for Object Relational Mapping an API that lets you save and retrieve 'objects' from a database without writing SQL statements. Because of this, there is no way to generate the if-then logic required by the idempotent migration scripts. Richard Hipp, SQLite was first released in August 2000. The SQLite.NET library that Xamarin recommends is a very basic ORM that lets you easily store and retrieve objects in the local SQLite database on an Android device. Unlike other databases, SQLite doesn't include a procedural language. |_ Composed: a sequence of Composable instances.
