SQLITE3SESSION_PATCHSET(3) Library Functions Manual NAME sqlite3session_patchset - Generate A Patchset From A Session Object SYNOPSIS int sqlite3session_patchset(sqlite3_session *pSession, int *pnPatchset, void **ppPatchset ); DESCRIPTION The differences between a patchset and a changeset are that: ⊕ DELETE records consist of the primary key fields only. The original values of other fields are omitted. ⊕ The original values of any modified fields are omitted from UPDATE records. A patchset blob may be used with up to date versions of all sqlite3changeset_xxx API functions except for sqlite3changeset_invert(), which returns SQLITE_CORRUPT if it is passed a patchset. Similarly, attempting to use a patchset blob with old versions of the sqlite3changeset_xxx APIs also provokes an SQLITE_CORRUPT error. Because the non-primary key "old.*" fields are omitted, no SQLITE_CHANGESET_DATA conflicts can be detected or reported if a patchset is passed to the sqlite3changeset_apply() API. Other conflict types work in the same way as for changesets. Changes within a patchset are ordered in the same way as for changesets generated by the sqlite3session_changeset() function (i.e. all changes for a single table are grouped together, tables appear in the order in which they were attached to the session object).
