Hi Steve,

The final solution that was provided by the poster would run extremely slowly when dealing with larger row counts and a simple way of avoiding this can be implemented that has practical uses in optimising complex queries in general.

I would be happy to explain with examples.

Please feel free to tackle it. If I don't hear something in about a month, I'll bump this topic.

Hi Steve,

As it's my first article for you it took longer than I expected to format and load onto your system. I still couldn't get the colours from my code to remain, any thoughts?

Just writing to let you know it was sent yesterday and I know it takes a couple of weeks to process.

Many thanks,

Claire
