Implements

IRepository..::..GetDbCount(IEntityFields2, IRelationPredicateBucket)

Remarks

This method performs a SELECT COUNT(*) FROM (actual query) and executes that as a scalar query. This construct is not supported on Firebird. You can try to achieve the same results by using GetScalar and AggregateFunction.CountRow, though those results can differ from the result returned by GetDbCount if you use a group by clause.
