When a constraint violation occurs, an immediate ROLLBACK occurs, thus ending the current transaction, and the command aborts with a return code of SQLITE_CONSTRAINT. When a UNIQUE constraint violation occurs, the pre-existing rows that are causing the constraint violation are removed prior to inserting or updating the current row. Use the following when no conflict action is specified. When a constraint violation occurs, the one row that contains the constraint violation is not inserted or changed. When a constraint violation occurs, the command aborts with a return code SQLITE_CONSTRAINT. When a constraint violation occurs,no ROLLBACK is executed so changes from prior commands within the same transaction are preserved. Used to allow returning sub-classes of Cursor when calling query. In addition to SQLite's default BINARY collator, Android supplies two more, LOCALIZED, which changes with the system's current locale, and UNICODE, which is the Unicode Collation Algorithm and not tailored to the current locale. See the Notepad sample application in the SDK for an example of creating and managing a database.ĭatabase names must be unique within an application, not across all applications. SQLiteDatabase has methods to create, delete, execute SQL commands, and perform other common database management tasks. Exposes methods to manage a SQLite database.
