Final answer:
To view SQL generated by Entity Framework, use the logging functionality in EF Core or the Database.Log property in EF 6. Configure logging to output SQL to the console or a file, or use an Interceptor in EF 6 for detailed access to the generated SQL.
Step-by-step explanation:
Viewing SQL Generated by Entity Framework
To view the SQL generated by the Entity Framework (EF), you can use several methods depending on the version of EF you are using. In EF Core, the logging functionality built into Microsoft.Extensions.Logging can be configured to log the SQL statements to the console, debug window, or to a file. Here's an example using the console:
using Microsoft.Extensions.Logging;
// ... other code
// Configure logging
builder.Services.AddLogging(b => b.AddConsole()
.AddFilter("Microsoft.EntityFrameworkCore.Database.Command", LogLevel.Information));
// ... other code
In EF 6, you can make use of the Database.Log property to output the SQL. You can assign a delegate like Console.WriteLine or another method to log the SQL to your chosen destination:
using System;
using System.Data.Entity;
// ... other code
// Assign logging function
context.Database.Log = Console.WriteLine;
// Now, when you execute queries, the SQL will be output to the console
If you need more detailed insights or wish to intercept the SQL for modification, you can also use the Interceptor feature in EF 6. This involves creating a class that derives from DbCommandInterceptor and overriding methods like ReaderExecuting to access the SQL before it's executed.
