SQLite C Interface

Virtual Table Cursor Object

struct sqlite3_vtab_cursor {
  sqlite3_vtab *pVtab;      /* Virtual table of this cursor */
  /* Virtual table implementations will typically add additional fields */
};

Important: This interface is experimental and is subject to change without notice.

Every virtual table module implementation uses a subclass of the following structure to describe cursors that point into the virtual table and are used to loop through the virtual table. Cursors are created using the xOpen method of the module and are destroyed by the xClose method. Cussors are used by the xFilter, xNext, xEof, xColumn, and xRowid methods of the module. Each module implementation will define the content of a cursor structure to suit its own needs.

This superclass exists in order to define fields of the cursor that are common to all implementations.
