wview 5.1.2 (Default branch)
wview is an application that controls a supported weather station to retrieve archive records and current conditions. Archive records may optionally be stored in a relational database (MySQL or PostgreSQL). At a user-defined interval, wview will use the archive history and current conditions to generate weather images (buckets and graphs) and Web pages based on configurable HTML templates. It supports serial and USB data loggers, as well as connectivity with a terminal server or serial server via TCP sockets. License: GNU General Public License (GPL) Changes:
This release fixes a bug for Vantage Pro stations that only occurred if there were no records in the wview-archive.sdb database (new install), which caused the wviewd daemon to never retrieve archive records because of a bad LastArchiveTime value ("retrying archive record..."). Image

ndb_delete_all

NDB_DELETE_ALL(1)					       MySQL Database System						 NDB_DELETE_ALL(1)

NAME

       ndb_delete_all - delete all rows from an NDB table

SYNOPSIS

       ndb_delete_all options

DESCRIPTION

       ndb_delete_all deletes all rows from the given NDB table. In some cases, this can be much faster than DELETE or even TRUNCATE TABLE.
	       Usage

	   ndb_delete_all -c connect_string tbl_name -d db_name

       This deletes all rows from the table named tbl_name in the database named db_name. It is exactly equivalent to executing TRUNCATE
       db_name.tbl_name in MySQL.

       The following table includes options that are specific to ndb_delete_all. Additional descriptions follow the table. For options common to
       most MySQL Cluster programs (including ndb_delete_all), see Options Common to MySQL Cluster Programs(1).

       Table 17.16. ndb_delete_all Options and Variables: MySQL Cluster NDB 7.2

       +--------------------------+-----------------------------------+-------------------------------------+

       o   --transactional, -t

	   Use of this option causes the delete operation to be performed as a single transaction.

	       Warning
	       With very large tables, using this option may cause the number of operations available to the cluster to be exceeded.
