I've just been asked whether there are any efficiency differences between CASE WHEN and DECODE. I'd imagined that they would use the same underlying code but perhaps not. Does anyone know which is more efficient (I realise that CASE is SQL-92 compliant and allows use of IN but excluding this is there any efficiency difference)
