The MartView front-end currently expects boolean columns to be non-null for true, and null for false. When generating the boolean columns, you'll notice you've got different optimiser types in MartBuilder. I think you've probably selected the one that says "0/1" or similar. If you change the type to the one that says "1/null" and regenerate then it should work nicely.
In the meantime, a 'quick fix' is to do a SQL update statement that replaces all the 0 values in your existing table boolean columns with nulls. cheers, Richard Moore, Jonathan wrote: > In our mart I have set up a main gene table and a number of dimensions, > with boolean optimiser columns in the main table, using martbuilder. > > In the resulting mart database, I have checked in the columns in the > main table and they have the correct values (a mix of 0 and 1). > However, in the results from martview, filtering to Include on an > optimiser column always returns all records and filtering to Exclude on > an optimiser column always returns no records.
