** <dt>SQLITE_CONFIG_ROWID_IN_VIEW
** <dd>The SQLITE_CONFIG_ROWID_IN_VIEW option enables or disables the ability
** for VIEWs to have a ROWID.  The capability can only be enabled if SQLite is
** compiled with -DSQLITE_ALLOW_ROWID_IN_VIEW, in which case the capability
** defaults to on.  This configuration option queries the current setting or
** changes the setting to off or on.  The argument is a pointer to an integer.
** If that integer initially holds a value of 1, then the ability for VIEWs to
** have ROWIDs is activated.  If the integer initially holds zero, then the
** ability is deactivated.  Any other initial value for the integer leaves the
** setting unchanged.  After changes, if any, the integer is written with
** a 1 or 0, if the ability for VIEWs to have ROWIDs is on or off.  If SQLite
** is compiled without -DSQLITE_ALLOW_ROWID_IN_VIEW (which is the usual and
** recommended case) then the integer is always filled with zero, regardless
** if its initial value.

** [sqlite3_int64] parameter which is the default maximum size for an in-memory
** database created using [sqlite3_deserialize()].  This default maximum
** size can be adjusted up or down for individual databases using the
** [SQLITE_FCNTL_SIZE_LIMIT] [sqlite3_file_control|file-control].  If this
** configuration setting is never used, then the default maximum is determined
** by the [SQLITE_MEMDB_DEFAULT_MAXSIZE] compile-time option.  If that
** compile-time option is not set, then the default maximum is 1073741824.

** [[SQLITE_CONFIG_ROWID_IN_VIEW]]
** <dt>SQLITE_CONFIG_ROWID_IN_VIEW
** <dd>The SQLITE_CONFIG_ROWID_IN_VIEW option enables or disables the ability
** for VIEWs to have a ROWID.  The capability can only be enabled if SQLite is
** compiled with -DSQLITE_ALLOW_ROWID_IN_VIEW, in which case the capability
** defaults to on.  This configuration option queries the current setting or
** changes the setting to off or on.  The argument is a pointer to an integer.
** If that integer initially holds a value of 1, then the ability for VIEWs to
** have ROWIDs is activated.  If the integer initially holds zero, then the
** ability is deactivated.  Any other initial value for the integer leaves the
** setting unchanged.  After changes, if any, the integer is written with
** a 1 or 0, if the ability for VIEWs to have ROWIDs is on or off.  If SQLite
** is compiled without -DSQLITE_ALLOW_ROWID_IN_VIEW (which is the usual and
** recommended case) then the integer is always filled with zero, regardless
** if its initial value.
