TFPExpressionParser.HasAggregate function

Declaration

function HasAggregate: Boolean

Function result

Returns true if expression has aggregates

Description

The HasAggregate method determines whether the current expression contains any aggregate functions such as Sum, Count, Average, Min, or Max. Aggregate functions require special handling during evaluation.

This information is important for determining the evaluation strategy, as expressions with aggregates may need multiple evaluation passes or special initialization steps.
