Conflict resolution modes
#define SQLITE_ROLLBACK 1 /* #define SQLITE_IGNORE 2 // Also used by sqlite3_authorizer() callback */ #define SQLITE_FAIL 3 /* #define SQLITE_ABORT 4 // Also an error code */ #define SQLITE_REPLACE 5
These constants are returned by sqlite3_vtab_on_conflict() to inform a virtual table implementation what the ON CONFLICT mode is for the SQL statement being evaluated.
Note that the SQLITE_IGNORE constant is also used as a potential return value from the sqlite3_set_authorizer() callback and that SQLITE_ABORT is also a result code.
