… WHERE some_column = NOT NOW

It took me a while to work out the flawed logic. However, it was still having the desired result because, although in VBA

? NOT NOW
-38707

in Jet SQL

Set rs = CreateObject(“ADOR.RecordSet”)
rs.Open “SELECT NOT NOW”, _
“Provider=Microsoft.Jet.OLEDB.4.0;” & _
“Data Source=/Nobook.xls;” & _
“Extended Properties=’Excel 8.0′”
? rs(0)
0

My point? That Jet operators aren’t bitwise; you have to specify the bitwise equivalent e.g. BNOT:

Set rs = CreateObject(“ADOR.RecordSet”)
rs.Open “SELECT BNOT NOW”, _
“Provider=Microsoft.Jet.OLEDB.4.0;” & _
“Data Source=/Nobook.xls;” & _
“Extended Properties=’Excel 8.0′”
? rs(0)

Did it work? Too bad there wasn’t a preview option.

Thanks

I had a need to discover ouliers from a list of sales ratios based on a factor of lower quartile and upper quartile. In order to return an array I had to use the following formula.

=AVERAGE(IF(NOT(NOT((RatioList>FactLowerLimit)*(RatioList
