❔ Mixing EF Core and another SQL library

Hello, I need to write some raw SQL queries outside the ORM but EF Core doesn't support that, how good is an idea of adding another SQL library to do those raw queries. It would be nice if I could split queries into seperate .sql files. Pls suggestions, thank you

I checked ADO.NET and it seems like what I'm looking for, is it a bad idea to have multiple db libs like this?

Dapper if anything But EF does let you execute raw queries

I saw Database.SqlQuery but it doesn't let me return objects only 1 scalar value as it says on docs Is there another way?

thx 😄 Hmm seems like [Keyless] creates the table, is this intended behavior?

Angius•2y ago

It shouldn't be creating one

seems like adding Keyless annotation did nothing,

         modelBuilder.Entity("rgm_api.Models.Keyless.Lala", b =>
                {
                    b.Property<uint>("Lala1")
                        .HasColumnType("int unsigned");

                    b.Property<string>("Lala2")
                        .IsRequired()
                        .HasColumnType("longtext");

                    b.ToTable("Lalas");
                });

         modelBuilder.Entity("rgm_api.Models.Keyless.Lala", b =>
                {
                    b.Property<uint>("Lala1")
                        .HasColumnType("int unsigned");

                    b.Property<string>("Lala2")
                        .IsRequired()
                        .HasColumnType("longtext");

                    b.ToTable("Lalas");
                });

this is the result I get in my modelsnapshot and this is from msdn

   modelBuilder
        .Entity<BlogPostsCount>(
            eb =>
            {
                eb.HasNoKey();
                eb.ToView("View_BlogPostCounts");
                eb.Property(v => v.BlogName).HasColumnName("Name");
            });

   modelBuilder
        .Entity<BlogPostsCount>(
            eb =>
            {
                eb.HasNoKey();
                eb.ToView("View_BlogPostCounts");
                eb.Property(v => v.BlogName).HasColumnName("Name");
            });

seems like this issue exists for a while.. found github issues from 2018-2022

I guess it creates a view, then, huh I'd say go with Dapper, then

barcode•2y ago

is it ok to mix ef core and dapper? no possible issues to arise?

Angius•2y ago

Ideally, don't use them to query for the same things, but it should be fine

barcode•2y ago

ty, using ef core to get and update 'simple' queries but I have some 60 liners that dapper will handle dapper works, gonna use it for selection and EF core for everything else, just feels wrong having 2 orms

BananaPie•2y ago

I used 2 ORMs back in the old EF 4~6 days. The old EF was pretty slow on large reads. So I used dapper for that and EF for updating.
