Syntax

public class ReplaceNonRecursiveAggregations : ChangeExpressions, IGenericExpressionVisitor<IEnumerable<Expression>>, IExpressionVisitor, IGenericVisitor<IEnumerable<Expression>>

Remarks

For examle, COUNT(x) gets replaced by SUM(x != null ? 1 : 0), AVG gets replaced by SUM / SUM (with the appropriate null value checks)
