를 SqlConstantExpression 방문하여 Null 허용 여부를 계산합니다.

protected virtual Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression VisitSqlConstant (Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlConstantExpression sqlConstantExpression, bool allowOptimizedExpansion, out bool nullable);
abstract member VisitSqlConstant : Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlConstantExpression * bool * bool -> Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression
override this.VisitSqlConstant : Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlConstantExpression * bool * bool -> Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression
Protected Overridable Function VisitSqlConstant (sqlConstantExpression As SqlConstantExpression, allowOptimizedExpansion As Boolean, ByRef nullable As Boolean) As SqlExpression

매개 변수

sqlConstantExpression
SqlConstantExpression

방문할 sql 상수 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.
