DatabaseFacade 不包含“ExecuteSqlCommand”的定义

Question

我希望在 EF Core 上运行原始 SQL 删除查询，并且我正在起诉以下指南来帮助我： https://learn.microsoft.com/en-us/ef/ef6/querying/raw-sql

代码：

using (accountingContext db = new())
{
    db.Database.ExecuteSqlCommand("DELETE FROM ...");
}

但我收到错误：

DatabaseFacade 不包含“ExecuteSqlCommand”的定义

我的accountingContext类：

using System;
using System.Collections.Generic;
using Microsoft.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore.Metadata;

namespace WebApi.Models
{
    public partial class accountingContext : DbContext
    {
        public DbSet<User>? Users { get; set; }
        public DbSet<Transaction>? Transactions { get; set; }
        public DbSet<TransactionStaging>? TransactionsStaging { get; set; }

        public accountingContext()
        {
        }

        public accountingContext(DbContextOptions<accountingContext> options) : base(options)
        {
        }
        protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
        {
            if (!optionsBuilder.IsConfigured)
            {
                optionsBuilder.UseSqlServer("****");
            }
        }

        protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
        }
    }
}

.csproj 文件：

<Project Sdk="Microsoft.NET.Sdk.Web">
    <PropertyGroup>
        <TargetFramework>net6.0</TargetFramework>
        <ImplicitUsings>enable</ImplicitUsings>
    </PropertyGroup>
    <ItemGroup>
        <PackageReference Include="CsvHelper" Version="28.0.1" />
        <PackageReference Include="Microsoft.AspNetCore.Authentication.JwtBearer" Version="6.0.0" />
        <PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="6.0.9">

          <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
        </PackageReference>
        <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="6.0.6" />
        <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="6.0.6">
          <PrivateAssets>all</PrivateAssets>
          <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
        </PackageReference>
        <PackageReference Include="Microsoft.Extensions.Configuration" Version="6.0.1" />
        <PackageReference Include="System.IdentityModel.Tokens.Jwt" Version="6.15.0" />
    </ItemGroup>
    <ItemGroup>
      <Folder Include="Resources\Temp\" />
    </ItemGroup>
</Project>

我在这里做错了什么？

Answer 1

以下内容为我解决了问题：

db.Database.ExecuteSqlRaw("...");

不确定为什么我正在阅读的所有文档都建议使用 ExecuteSqlCommand，但最终我偶然发现了正确的命令。

Answer 2

您需要添加以下软件包才能使用 EF 6.0：

不要使用任何其他EntityFramework包。另外，您的解决方案应该适用于 .Net 6.0。

Answer 3

对于 EF Cor，您需要使用扩展 Nuget 包中包含的 ExecuteSqlRaw 或 ExecuteSql 命令 Microsoft.EntityFrameworkCore.Relational

Answer 4

使用 Microsoft.EntityFrameworkCore.SqlServer
