# This isn't to be run.  Do not chmod it +x and try - it won't do anything.

# This function will change or create entries in various tables within
# the mythconverg database.
# If the key value already exists in $SQL_FILENAME, then it is changed.  Otherwise,
# it will create the necessary SQL to make the entry if it does not exist.
#
# For the purposes of this function, a key is defined as any unique string of text
# after which a comma and a value or values follow.  E.g.:
# in an entry like this:
# INSERT INTO `videotypes` VALUES (6,'mpeg','',0,1);
# we can define the key as "6" if we wanted, but that would be ambiguous.  So we can instead
# define it as "6,'mpeg'" and we gain the ability to control the values of the fields after
# the first two.  So this function call
#
# ChangeOrMakeEntry "6,'mpeg'" "'mplayer -fs -zoom', 0,1" "videotypes"
#
# would change the above SQL entry into this:
#
# INSERT INTO `videotypes` VALUES (6,'mpeg','mplayer -fs -zoom', 0,1);

# parameters: name, value, table

# Some tables have simple key, value pairs.  Others have several potential keys and values.
# The 'settings' table is a simple key, value pair table, plus the name of the system on which
# the settings hold true, e.g.:
# INSERT INTO `settings` VALUES ('FooHat','Peas with sauce:drizzle','MythTVhost');
