FlowFilters problems with vb application

Mct

Hello,

I have a visual basic application working with nav2.6 and i try to upgrade it for can be using by nav 5.0. With nodbc, i display informations through some sql request. In some request, I need a flowfield so i fill a flowfilter like explain in official manual.

{pred SetFlowFilterMultiple, "TableName". "FieldName", 'A
searchString'}

It work well but in majority of my sql request, I need 2 or 3 different information which given to me by the same flowfield (by changing the flowfilter value). With the official method, there's no solution and i think multiply sql request isn't a good solution.
According to you, what is the best solution???
Thx
