     sqlite3session_attach - Attach A Table To A Session Object

     sqlite3session_attach(sqlite3_session *pSession,
         const char *zTab                );

     If argument zTab is not NULL, then it is the name of a table to attach to
     the session object passed as the first argument.  All subsequent changes
     made to the table while the session object is enabled will be recorded.
     See documentation for sqlite3session_changeset() for further details.

     Or, if argument zTab is NULL, then changes are recorded for all tables in
     the database.  If additional tables are added to the database (by
     executing "CREATE TABLE" statements) after this call is made, changes for
     the new tables are also recorded.

     Changes can only be recorded for tables that have a PRIMARY KEY
     explicitly defined as part of their CREATE TABLE statement.  It does not
     matter if the PRIMARY KEY is an "INTEGER PRIMARY KEY" (rowid alias) or
     not.  The PRIMARY KEY may consist of a single column, or may be a
     composite key.

     It is not an error if the named table does not exist in the database.
     Nor is it an error if the named table does not have a PRIMARY KEY.
     However, no changes will be recorded in either of these scenarios.

     Changes are not recorded for individual rows that have NULL values stored
     in one or more of their PRIMARY KEY columns.

     SQLITE_OK is returned if the call completes without error.  Or, if an
     error occurs, an SQLite error code (e.g.  SQLITE_NOMEM) is returned.
