EF Core 3.0无法从Oracle DB视图获取数据

如何解决EF Core 3.0无法从Oracle DB视图获取数据

在使用ORacle Entity Framework Core和.Net EF core 3.0时，我无法从Oracle View检索数据，但是表正在返回数据。

Context..ToList（）始终显示0个结果，没有错误。

该模型是通过Scaffold-DbContext与Oracle DB连接生成的

代码示例：

模型上下文

public virtual DbSet<XxegcXerpSalesmanMasterV> XxegcXerpSalesmanMasterV { get; set; }

modelBuilder.Entity<XxegcXerpSalesmanMasterV>(entity => {
    entity.HasNoKey();
    entity.ToView("XXEGC_XERP_SALESMAN_MASTER_V","APPS");
    entity.Property(e => e.CreationDate).HasColumnName("CREATION_DATE") .HasColumnType("DATE");
    entity.Property(e => e.Division).HasColumnName("DIVISION") .HasMaxLength(150) .IsUnicode(false);
    entity.Property(e => e.EndDateActive).HasColumnName("END_DATE_ACTIVE") .HasColumnType("DATE");
    entity.Property(e => e.LastUpdateDate).HasColumnName("LAST_UPDATE_DATE") .HasColumnType("DATE");
    entity.Property(e => e.MainWhCode).HasColumnName("MAIN_WH_CODE") .HasMaxLength(3) .IsUnicode(false);
    entity.Property(e => e.MainWhName).HasColumnName("MAIN_WH_NAME") .HasMaxLength(240) .IsUnicode(false);
    entity.Property(e => e.OrgId).HasColumnName("ORG_ID") .HasColumnType("NUMBER");
    entity.Property(e => e.ResourceId).HasColumnName("RESOURCE_ID") .HasColumnType("NUMBER");
    entity.Property(e => e.ResourceStatus).HasColumnName("RESOURCE_STATUS") .HasColumnType("CHAR(1)");
    entity.Property(e => e.RouteCode).HasColumnName("ROUTE_CODE") .HasMaxLength(16) .IsUnicode(false);
    entity.Property(e => e.RouteType).HasColumnName("ROUTE_TYPE") .HasMaxLength(150) .IsUnicode(false);
    entity.Property(e => e.SalesmanName).HasColumnName("SALESMAN_NAME") .HasMaxLength(1412) .IsUnicode(false);
    entity.Property(e => e.SalesmanNumber).HasColumnName("SALESMAN_NUMBER") .HasMaxLength(30) .IsUnicode(false);
    entity.Property(e => e.SalesrepId).HasColumnName("SALESREP_ID") .HasColumnType("NUMBER");
    entity.Property(e => e.StartDateActive).HasColumnName("START_DATE_ACTIVE") .HasColumnType("DATE");
    entity.Property(e => e.VanSubinv).HasColumnName("VAN_SUBINV") .HasMaxLength(30) .IsUnicode(false);
});

类定义

namespace MVC_oracle.Models
{
    public partial class XxegcXerpSalesmanMasterV
    {
        public decimal ResourceId { get; set; }
        public string SalesmanName { get; set; }
        public string SalesmanNumber { get; set; }
        public string RouteCode { get; set; }
        public string RouteType { get; set; }
        public string VanSubinv { get; set; }
        public string MainWhCode { get; set; }
        public decimal? OrgId { get; set; }
        public string Division { get; set; }
        public decimal SalesrepId { get; set; }
        public string ResourceStatus { get; set; }
        public DateTime? CreationDate { get; set; }
        public DateTime? LastUpdateDate { get; set; }
        public DateTime StartDateActive { get; set; }
        public DateTime? EndDateActive { get; set; }
        public string MainWhName { get; set; }
    }
}

控制器类：

private readonly ModelContext _context; 
var SalesMans = _context.XxegcXerpSalesmanMasterV.ToList(); // Not getting data here
