SQLITE_CHANGESET_DATA(3)   Library Functions Manual   SQLITE_CHANGESET_DATA(3)

NAME
     SQLITE_CHANGESET_DATA, SQLITE_CHANGESET_NOTFOUND,
     SQLITE_CHANGESET_CONFLICT, SQLITE_CHANGESET_CONSTRAINT,
     SQLITE_CHANGESET_FOREIGN_KEY - Constants Passed To The Conflict Handler

SYNOPSIS
     #define SQLITE_CHANGESET_DATA
     #define SQLITE_CHANGESET_NOTFOUND
     #define SQLITE_CHANGESET_CONFLICT
     #define SQLITE_CHANGESET_CONSTRAINT
     #define SQLITE_CHANGESET_FOREIGN_KEY

DESCRIPTION
     Values that may be passed as the second argument to a conflict-handler.

     SQLITE_CHANGESET_DATAThe conflict handler is invoked with CHANGESET_DATA
             as the second argument when processing a DELETE or UPDATE change
             if a row with the required PRIMARY KEY fields is present in the
             database, but one or more other (non primary-key) fields modified
             by the update do not contain the expected "before" values.

             The conflicting row, in this case, is the database row with the
             matching primary key.

     SQLITE_CHANGESET_NOTFOUNDThe conflict handler is invoked with
             CHANGESET_NOTFOUND
             as the second argument when processing a DELETE or UPDATE change
             if a row with the required PRIMARY KEY fields is not present in
             the database.

             There is no conflicting row in this case.  The results of
             invoking the sqlite3changeset_conflict() API are undefined.

     SQLITE_CHANGESET_CONFLICTCHANGESET_CONFLICT is passed as the second
             argument to the conflict handler while processing an INSERT
             change if the operation would result in duplicate primary key
             values.

             The conflicting row in this case is the database row with the
             matching primary key.

     SQLITE_CHANGESET_FOREIGN_KEYIf foreign key handling is enabled, and
             applying a changeset leaves the database in a state containing
             foreign key violations, the conflict handler is invoked with
             CHANGESET_FOREIGN_KEY as the second argument exactly once before
             the changeset is committed.  If the conflict handler returns
             CHANGESET_OMIT, the changes, including those that caused the
             foreign key constraint violation, are committed.  Or, if it
             returns CHANGESET_ABORT, the changeset is rolled back.

             No current or conflicting row information is provided.  The only
             function it is possible to call on the supplied
             sqlite3_changeset_iter handle is sqlite3changeset_fk_conflicts().

     SQLITE_CHANGESET_CONSTRAINTIf any other constraint violation occurs
             while applying a change (i.e.  a UNIQUE, CHECK or NOT NULL
             constraint), the conflict handler is invoked with
             CHANGESET_CONSTRAINT as the second argument.

             There is no conflicting row in this case.  The results of
             invoking the sqlite3changeset_conflict() API are undefined.
