namespace Appeon.ApiDoc.ISqlExecutorExamples
{
    public class ExecuteProcedureExample
    {
        private readonly SchoolContext _context;

        public ExecuteProcedureExample(SchoolContext dataContext)
        {
            // Sets the data context
            _context = dataContext;
        }

        public void Example()
        {
            // Specifies the procedure to be executed.
            // It inserts a person record to database and returns the new PersonID.
            var procedureName = "GetDepartmentName";

            /* StoredProcedure GetDepartmentName：
            
            CREATE PROCEDURE[dbo].[GetDepartmentName]
            @ID int,
            @Name nvarchar(50) OUTPUT
            AS
            SELECT @Name = Name FROM Department
            WHERE DepartmentID = @ID

            GO
            */

            // Sets the parameter values.
            // The parameter direction defaults to ParameterDirection.Input,
            // so you can omit it.
            var idParam = ParamValue.New<string>("id", "4");

            // The parameter 'Name' is Output type.
            var nameParam = ParamValue.Output<string>("name");

            // Executes the SQL statement and gets the department by nameParam.
            _context.SqlExecutor.ExecuteProcedure(
                procedureName, idParam, nameParam);

            Console.WriteLine("Department Name: {0}", nameParam.Value);

            /*This code produces the following output:

            Department Name: Economics
            */
        }
