Скачать или смотреть Dapper - Part 2 - Executing Scalar Queries | ExecuteScalar | ExecuteScalarAsync

In this video we will explore how we can execute scalar database queries using dapper.

In this demo we will use SQL Sever database, C# programming language and .NET 9 MVC application.

ExecuteScalar - Returns the first column of the first row as a dynamic type

ExecuteScalar- Returns the first column of the first row as the specified T type parameter

ExecuteScalarAsync{T} - Returns the first column of the first row as the specified T type parameter asynchronously
