I am trying to create a query that will show give me all records where >50% or the child records match the comparison criteria. Specific example: I want to see all loans in which >50% of the collateral properties are in our assessment area. The parent record contains the loan number, which has a one-to-many relationship with the collateral properties. The census tracts of the collateral properties are compared to the census tracts in our assessment area. I want a query that doesn't just give me the First collateral property that matches. I want to see only those where >50% of the total collateral properties of a loan are in the assessment area (have matching census tracts).
