UkrGuru.SqlJson is very easy and fast access to the Sql Server database and EF Core is not involved in this.
I'm an old software developer with over 20 years of experience and have written a lot of unique code in my life. In my practice of working with data, I usually use SQL Server and stored procedures to execute queries of any complexity. Last year I tried to use the Microsoft EF Core framework, but I always lacked the power that I had when using the procedures earlier. Eventually my patience ran out and I created a minimally simple UkrGuru.SqlJson package for modern data processing, and now I want to share this knowledge with you...

}var builder = WebApplication.CreateBuilder(args);
builder.Services.AddSqlJson(builder.Configuration.GetConnectionString("DefaultConnection"))
.AddSqlJsonExt(builder.Configuration.GetValue<DbLogLevel>("Logging:LogLevel:UkrGuru.SqlJson"));
// More other services here ...
var app = builder.Build();@code {
public List<ProductDto>? Products { get; set; }
protected override async Task InitData() { Title ??= "Products"; await Task.CompletedTask; }
protected override async Task LoadData() {
Products = await db.ReadAsync<List<ProductDto>>("Products_Grd");
}
protected override async Task InsItemAsync(GridCommandEventArgs args)
=> await db.CreateAsync<int?>("Products_Ins", (ProductDto)args.Item);
protected override async Task UpdItemAsync(GridCommandEventArgs args)
=> await db.UpdateAsync("Products_Upd", (ProductDto)args.Item);
protected override async Task DelItemAsync(GridCommandEventArgs args)
=> await db.DeleteAsync("Products_Del", ((ProductDto)args.Item)?.ProductId);
}UkrGuru.SqlJson automatically normalizes input parameters and deserializes the result.
Requirements:
- INPUT: Must use a query or procedure with only one @Data parameter of any type, or no parameter.
- OUTPUT: Should prepare the result in one column SELECT varchar or json types. See more examples bellow ...
