Hence, please refer to the documentation for “” to see the complete documentation for this Slots, instead of the generic, and/or polymorphistic slots. If you replace the or slots with, you will use the sqlite specific Transparently use the same lambda object, towards any of the database types Magic supports, without having toĪll of the slots in this project are documented in the documentation for the “” project.

Use the same lambda object, towards any of the underlaying database types, and the correct specific syntaxįor your particular database vendor’s SQL syntax will be automatically generated. Notice - If you use any of the CRUD slots from above, the whole idea is that you can polymorphistically - Flushed cached schemas and connection pools.- Explicitly rolls back an open transaction.- Explicitly commits an open transaction.- Executes an aribitrary SQL statement.- Executes an arbitrary SQL statement, and returns the result as a scalar value to caller.- Executes an arbitrary SQL statement, and returns results of reader as lambda objects to caller.- Deletes a single record in the specified table.- Updates a single record in the specified table.- Reads multiple records from the specified table.

- Creates a single record in the specified table.Such allows you to declare your own SQL statements to be executed towards a SQLite database.
