modbus device bus_write option modified by scipt

[domotiqa]

here

Code:

searchKey='bus_write'
valueSearch='1'
oldValue='1'
newValue='0'
key='bus_write'
mytable='modbus_mapping'


if oldValue =='' then
  querySql="UPDATE "..mytable.." SET "..key.." = "..newValue.." WHERE "..searchKey.." like '%"..valueSearch.."%'"
else
    querySql="UPDATE "..mytable.." SET "..key.." = REPLACE("..key..", '"..oldValue.."', '"..newValue.."') WHERE "..searchKey.." like '%"..valueSearch.."%'" 
end

db:query(querySql)

I precise that after my script, if I go to modbus the write option is disabled on all element
