Database editing script

The script is a template for changing the default channel numbers in the mythtv database. for UK DVB-T (Freeview) to a more sensible range of numbers, it's pretty self explanatory and can be used as a template by users in other countries wishing to do the same thing.

Specific scripts for UK freeview, freesat and combinations system are available on this page: UK_Channel_Assignments

The script is ideal for resetting your channels immediately after a rescan and saves time messing around doing it manually or via mythweb (my previous preferred route). Change the value in channum below to your preferred Channel Number for the channel defined by callsign. This script references the MythTV config file to get database login details, so you don't have to type them in or include them in the script, edit the path (~/.mythtv/mysql.txt) if required to suit your setup.

To find out what channels you should have, and their xmltv ids, see Uk_xmltv#How_to_find_out_which_channels_are_available_and_what_their_xmltv_IDs_are:. This script doesn't configure your xmltv grabber (you have to do that yourself,Uk_xmltv), it just sets the required id in the channel table.

Please use common sense and back up your database BEFORE running this script, if it eats your database it's not our fault!!

The following SQL statements maybe of use: This will hide all channels where there isnt any guide data available.

UPDATE channel SET visible=0 WHERE channel.chanid NOT IN (SELECT DISTINCT(chanid) FROM program);

And; mark no comm-flagging on BBC channels

UPDATE channel set commmethod=-2 WHERE name LIKE '%BBC%' OR name = 'CBeebies';  

 #!/bin/bash
 
 # Set MythTV channel numbers
