Raw SQL queries and Entity Framework Core

问题

I migrate my application to ASP.NET MVC Core and Entity Framework Core and i found problem. I have raw SQL query to entity like this

var rawSQL = dbContext.Database.SqlQuery<SomeModel>("Raw SQL Query").ToList();

But there is no SqlQuery<T> in context.Database. Do you have solution for this problem?

回答1:

Make sure you add using Microsoft.Data.Entity; because there is an extension method you could use.

var rawSQL = dbContext.SomeModels.FromSql("your SQL");

Even better, instead using raw SQL (at risk of SQL injections attacks) this FromSql method allows you to use parameterized queries like:

dbContext.SomeModels.FromSql("SELECT * FROM dbo.Blogs WHERE Name = @p0", blogName);
