를 DistinctExpression 방문하여 Null 허용 여부를 계산합니다.

protected virtual Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression VisitDistinct (Microsoft.EntityFrameworkCore.Query.SqlExpressions.DistinctExpression distinctExpression, bool allowOptimizedExpansion, out bool nullable);

abstract member VisitDistinct : Microsoft.EntityFrameworkCore.Query.SqlExpressions.DistinctExpression * bool * bool -> Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression
override this.VisitDistinct : Microsoft.EntityFrameworkCore.Query.SqlExpressions.DistinctExpression * bool * bool -> Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression

Protected Overridable Function VisitDistinct (distinctExpression As DistinctExpression, allowOptimizedExpansion As Boolean, ByRef nullable As Boolean) As SqlExpression

매개 변수

distinctExpression

DistinctExpression

방문할 데이터 정렬 식입니다.

allowOptimizedExpansion

Boolean

null 값을 false 값으로 간주하는 최적화된 확장이 허용되는지 여부를 나타내는 부울 값입니다.

nullable

Boolean

sql 식이 null 허용인지 여부를 나타내는 bool 값입니다.

반환

SqlExpression

최적화된 sql 식입니다.
